Hello everyone, new to the forum and G40 life, bought a g40 with a lysholm charger bolted on and setup well!
one issue is its super loud and isnt really practical for daily use!
the throttle doesnt move enough and idles at 2000 on tick over, the rod underneath is bent and held together with cabletie.. not the best
i plan to sort this and see if the charger is bearable at low revs because i love how it pulls and the sound when giving it some,
other option is another charger but not sure whats best and what i would need to convert back to standard g40 charger or a slightly uprated charger...
Please help :)
any comments would be great!
thanks
Can you get a pick up of the G40 throttle body? Have you tried loosening the throttle cable?
In terms of another charger if you were to change an Eaton set up wouldn't be too difficult!
Theres not a great deal you can do about the noise. And eatons arnt much quieter
Might be worth going back to glader? A ported one though :)
Ah you must be the person who bought the red g40 from poole area?
You can actually buy a silencer kit from lysholm. Not sure how much difference it makes though. I think that the charger you have is actually what the G60 engine uses as its really small. But you can run 22psi on a standard pulley which is crazy. Get it all sorted and mapped and that will make some great power.
If this is the one im thinking about, Throttle body is standard iirc, was a g40 cup engine and had wire locking on it.
This the one you got?
http://www.polog40.co.uk/forum/index.php?topic=9243.0
yep thats the one, i think the part holding the cable is bent forward to move the tick over up for race purposes? its held together with cable ties, bit worrying, goes like shit off a shovel
could you link me to a silencer kit, would be very interested
Got a de wedged throttle body if you need one
tbh fella dont even know what that is, a little bit clueless when it comes to g40 engines :S
On the butterfly valve inside the throttle body, vw stuck 2 big wedges inside. Apparently to make it slower or something. But most people tend to remove this to make it less restrictive.
You can tell if your has been done by simply removing the t-piece on top with allen keys. You should see 1 black wedge and 2 screws holding it in place. But it might of been removed already.
And will have a look for the silencer kit. Think you have to order it from usa unless you speak to matt at only charged dubs as he his an authorised bbm seller and could probably get this in for you.
http://www.onlychargeddubs.co.uk/
Will look for kit now.
Also check if it is defiantly a lysholm, as it does look more like a BBM charger as in the link below
http://www.bahnbrenner.com/vw_audi/products/2652/NEW_BBM_G60_SUPERCHARGER_KIT
Right, they dont do them anymore mainly due to a problem with them breaking.
All it is, is a longer inlet pipe with the filter on, and cause of its length and the charger twisting it caused the welds to break after some time. You could see if you could make the pipe work for inlet longer, but i dont think it will dampen out the sound that much. With that charger, its gonna be loud no matter what you do. But if it is a bbm one you will sell it quite quick if you decide to sell it.
On dubforce there is always someone looking into it, not to mention someone off here would snap it up. I nearly bought the charger off sam, who was the owner who had it all done, when he was gonna break it.
Them chargers can run up to 2 bar of boost and on the g60 engine they can make up to 300bhp.
Would be worth keeping if you wanted to get more power.
doesnt look like the one in the link, and have been told its a lysholm, sound like one too!
2 bar of boost!! No way!
If you sell that charger ill swap you for a recently rebuilt jabbasport r1 glader lol
Just saying :P
BBM and Lysholm sound almost the same.
There usually over £2000!
might be a good shout! got any pictures and would it be straight forward swap for the chargers? i.e take mine off and new one bolts straight in?
im sorry i have no idea about G's :/ need to learn quick!
Have a read around the forum dude, you will need to check your ecu chip injectors etc. make sure all the bits arnt specific to the charger. That includes the cam too
Wow thats expensive! Yes it would be bolt on once youve removed all the bracketry from yours. Though its not really fair as like jezza said the lysholm charger is worth £2000 whereas my glader is worth £400 (ported and rebuilt)
Cheers tom, just been thinking about this. Ive got a custom map and an ecu with a lower map sensor and a glader specific cam. But as long as i can get it running and get a cam at a later date. I was planning on getting a remap at a later date so yoof could then put then uprated map sensor in and map it then
Like the Eatons, the only real way to quieten one of these down is to have them sucking through the throttle body instead of blowing through it. At least that way when the throttle's closed you're damping some of the intake noise.
You could always try adding a throttle body on the inlet of the charger as well as retaining the standard one. I'd imagine getting the cable working properly might be a bit of a pig though. Or maybe you could actuate it with a vacuum/boost controlled device.

Is that what the cooper s has on it?
Maybe worth looking at one to get some ideas? Cooper s as standard are quite quiet. The superchcharger isnt very loud at all, compared to how they sound on g40 conversions
Bmw must have got it spot on
well tbh if i dont wantmy setup its worthless to me, if you swing a bit of cash my way i would be very happy to swap!
lysholm are too loud for my liking, sounds cool but i couldnt drive it every day, maybe as a track car which was its owners purpose was.
Here is a G40 with an air raid siren:
http://www.youtube.com/watch?v=epw1EZatQ2Q
Beleive this to be phil j's old car.
And this with an air box (not quieter at all)
http://www.youtube.com/watch?v=JBUN3c8D3Ss
And this is a good one for the sound whilst driving in a built up area, G60 rado though.
http://www.youtube.com/watch?v=dxhDLMrlL4Q
The bracket that is on the car is also custom made.
Sam, you would need a new set of pulleys, charger bracket, charger, outlet elbow, pipe work and then air filter pipe work.
Oh and blanking plate or boost return pipework. I think the injectors are G60? Check if they are green.
Keep the standalone oil system you have though, thats worth keeping.
If you want a set of standard pulleys i got them you can have as they are of no use to me, but if you want PSD toothed ones expect to pay around £200 mark, although some recently went for a lot less.
Charger will cost anywhere between £250-£500 ported or standard. Outlet elbow a few £ and pipe work slightly more cause you got a front mount.
You can sell the charger setup for over £1000, or swap it for someone with what you need plus cash your way. Or sell it and get a G45 charger.

They used to sell new nearer to the £2800 mark i think.
£2800!! Dayum!!
Thats too much for me, youll get a better deal selling it on here as a kit then buying a charger and the other stuff. Might take a bit longer to sell but in the long run
if i had a bit of cash id swap you all my g40 bits and monies
Also i think it sounds friggin awesome!! Lol
Yeah but they wont go much for more than 1k these days. Plus that was a new price.
if the throttle had been placed before the charger, it would have reduced the noise, heat and parasitic load on the engine on all but full-throttle.
Thats why dragster chargers are fairly quiet.
Speak to Jonny Betz and BBM to find out more. There a bit reluctant to give out some info though as i once found out.
hasnt got anything on the end of the camshaft, i assume its standard!
Sam said it was completely standard.
which sam haha? im confused
he was the owner who had the charger put in.
so the engine itself is completely g40 standard?
Yeah i believe so, i will ask sam himself about it.
Yep, standard cup car engine.
Where you located?
im in evesham, Worcestershire, why?
I do like the differant loader chargers that u can go for but after a while i think it would piss me off! A g60 charger is annoying tbo aswell but i like the noise to the g40 charger no to loud and dont annoy me tbo, its up to u mate they do sound cool as hell but are just too load imo but its nice to see differat chargers on polos so i say if u like it and the way it drives stick with it and make it as practical and fun as u can :)
To be honest, the main reason i want it is for reliability, i love the glader i think its awesome and i like how efficient it is. But i plan on alot more europe excursions and i really really really dont want my lader blowing up in a rural part of switzerland in the cold lol

It likely won't, they're not as bad as people make out. My car has done 205k miles on 2 charger services, on the original charger. Keep it serviced and it'l be fine. Thats a thousand times easier than going Eaton or Lysholm. Turbo is the most reliable and less work than an Eaton.
Or, use a different car to go driving around in.
More reliable and less work? Why u people keep saying that, a turbo more reliable than a charger? A turbo conversion needs a turbo, exhaust manifold, downpipe, injectors, cam, oil and maybe water lines, program and a bigger intercooler just to make it run? How is that less work than an eaton? All an Eaton needs is the charger, pulleys from 6n, the brackets and pipework to the original intercooler and it will work trouble-free! Maybe some reprogramming would be ideal but mine was working fine for more than 5 years without one and still made 143hp!
Cheers justin, thats some pretty impressive results! Your running toothies and a 65mm pulley? It still worries me. The horror stories of peoples ladders blowing up after a fresh rebuild. Though ive done 5k since my rebuild, and it feels so smooth to turn by hand, hardly any resistance on the pulley
Not going eaton, not very effcient, they are power sapping and getting expensive now (for the ones with teflon blades)
Justin was saying its cheaper to stay glader than go turbo or eaton. Ive yet to see an eaton make good power too
Turbo is out of the question, too much hassle and just spent £1k on supercharger parts, toothies and ppp manifold, would be a waste, plus you loose that lovely whine :) looks like im staying lader then
Ryan are you talking about a G60 charger in general?
When i bought my G40, it had a standard charger and never had a service. I never had it serviced till it came off the car and that had covered nearly 100k. It always ran an airbox with paper filter. VW never specified a service and i think that without a service they could go on for quite along time, more than the recommend mileage that people say. As mine did twice that. But everyone drives a car differently and every charger is different.
Its when you start putting induction kits on the charger (which let loads of small dirt particles through), 65mm pulleys (especially toothed) then doing the boost return mod (spraying grease inside which dirt sticks to) that fu**s them up. But thats boring not to do lol.
Most of the G60 guys are really against the boost return mod on the charger and also putting the induction kits on. You'd be surprised how many of them actually run standard air box's and some make 250bhp. They also run 68mm pulleys and very few people run toothed pulleys.
Turbo is more reliable than g-lader but its an expensive route to take.
There is a kit that is out for the G60 but could easily be made to suit a G40, with regards to boost return mod. Someone has made a blanking plate with an adapter on it, a 25mm hose and all you do it connect the hose to the breather and then to the charger blanking plate. You've got rid of the return of hot air but your still taking in the oil from crank which ideally the charger wants. Need to look into it though a bit more as i fancy this.

Dont get me wronge i dont think there is anything wringe with the g60 charger and if i could make my box stronger i would do it but all i was on about is noise conparison the g60 has a completly differant noise the the g40 imo i do like a loud charger i think it sound awsome when u here one screaming past you on the motorway but there is somthing i like about the g40 charger that makes me want to keep it.
I can still get 180 ish bhp out of one maybe 190 at a push and in a polo that waighs nothing, i think that plenty for road use. If i was going for reliability i would just go turbo and if i start doing more track i will propibly end up going turbo because of the power increase.
But saying that i cant say anything about eaton and lysholm becuse ive never ran one but there are loud and would do my head in after a while lol
Yeah, ive resorted back to standard air box and paper filter, no need for an induction kit (other than for cold ait intake)
People use too much ptfe spray on the boost return mod, and ive now done it as i wasnt happy with the oily/watery shit going back into the charger (cant be good for apex seals)
G60 chargers are pretty quite imo. On a G40 they sound different with small pulleys but i think of it as more of a droney sound, and then when it boosts it sounds different again. When a G60 and G40 are next to each other both running standard pulleys they sound the same.
Taylor cause your running an airbox and using ptfe grease, with the boost mod, it should be fine.
What you wanna do is try modify the airbox like this:
http://www.swgmotorsport.com/asps/ShowDetails.asp?id=172
That will be the best thing to do. But it might be a tight squeeze lol.
Been g60 researching already jezza? :P
Still cant believe you have both, might just get a loan and buy one lol, so dam awesome!
I do like g60s but i like the idea of g45 ;) maxrpm sell them now but are like 750 :O
And u have to exchange it.
Yeah, im very tempted to get a G45 just to see what all the fuss is about. I like it better than a G60 blower, although the power would be great, i think its too much torque. Not to mention by the time you start getting a G60 charger, charger outlet (which are expensive!) brackets, map sensor, pulleys, custom pipework, FMIC, bigger injectors (as i would think you would go over 200bhp), its soo expensive and a G45 would be a cheaper idea. No mods or nothing, just get it out the box, bolt on and get it mapped.

Ah awesome! I look forward to seeing it :)
Well youve got the highly modified g40 and can only imagine chasing hp's on the g60 will be expensive
One of those g45 chargers came up for sale on here recently. It still went for strong money even though it was used
Any idea the pressure output difference between a 40mm and 45?

A paper filter and an oil breather = a happy charger. I drive my car pretty hard all the time running a 65mm (well 2x drive ratio, standard is 1.6x) on the toothed pulleys. Keep a new filter in, keep the oil good and clean and its not a problem, less hassle and you never need to think about it. PTFE is horrid stuff. Apex seals will be fine with a little bit of oil mist in there, probably better than the sticky PTFE (probably a negligible amount of boost loss without the PTFE)
I have a spare Lader that will probably be sent to be converted to a G45 when I return home. Although my living in Canada seems to be getting extended every month I'm here.
Hmmm thinking about not doing the boost return now. Wanted to do it originally because wasnt happy with oil being sucked back into the engine and loweribg the fuels octane when being burnt
So oil is better than ptfe? I used a bit too much klubber grease when i serviced mine :(
Should i do it or not?
James with the g45 u not think u will need a bigger map sensor? I guess its not that much more boost will be interesting to see the differance in power coparing the 40 to the 45 i recon u will be hitting around 200 with a 45 if u have a high spec?!
Lets not fuck about now. just get this
http://img6.imageshack.us/img6/2459/img9189fn.jpg
ha yh why not lol,
looking at the g45 u get a 0.15bar increase so 2.2 psi
and u can do it both ways so 750 euros if u give them a exchange or 999 euro if u don't!
thats a lot of money for what u get so ur looking around 17 psi out of it when its heathy
shit starts to get expensive lol but still u shouldn't need to do any additional mods it just plug and play
where as g60 will cost a lot more any u will probably go though one every year lol
hmmm best start saving ha
Thats alot of money man! cant see it being worth it!
yh thats what i thought

Id build your g40 as you are now, its probably gonna be the most powerful glader 40 powered g40 on the forum
Once youve got used to it and still wanting more power, then look at other routes, but tbh i dont think you will want too, my g40 has a generic map, no bvh and has more potential YET its still mental fast so can only imagine how yours will be
ill take ur word dude i think thats the best other wise ill have chargers coming out my ears lol
On rolette racing website, who make the G45, it does say that they process an average of 0.35 bar which is 5 psi. So you might need one but think it would be worth asking them what they use. I used to get 18psi with only de wedge and gt inlet and never had a problem.
Now the only thing i never did (wish i did) is get big valves, but i only see 12psi on my gauge now and run somewhere between 170-180 i reckon. Maybe with the G45 i would see 17psi but the airflow increases by 12% which is quite good.
Justin, the G60 engine lubricates the charger from the top of the rocker cover and was thinking that if you drilled into the G40 rocker cover, make an adapter to fit, run a hose from that to the inlet of the blanked charger that way you retain the "lube" properties and can keep the oil going in, rather than ptfe. Reckon it would work the same as the G60? Plus you can stop the hot air from recirculating.
This is what i was trying to find, but making for the G40 charger and then hose to breather.
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=141057161312
Obviously this is well over priced.
That looks like a dam good idea! Put an inline water seperator on there and boom
Would never be able to sort the water problem out as the heat from the block/pipe would cool and form very small water droplets as it hits the cool metal of the charger.
Cool metal on the charger? Mine gets so hot you cant touch it!!
From what ive seen rothelle and max rpm porting is nothing like a good full blend or r1 or g werks not as ported
Mine never gets got. My air filter is down the front bumper so no heat soak at all.

Hmm this is worrying, think mine soaks up alot of heat from the exhaust? Maybe my ppp one will give more clearance?
Maybe a mixture of, decent intercooler, seperate oil feed, oil cooler and relocated air filter keeps yours nkce and cool? Must make a bjg difference on performance and seals lasting longer, my bay has always got stupid hot, sometimes the water gauge gets too 100degrees, thought ive now fitted a lower temp stat
Maybe the rotthelle could produce more boost with porting?
My water rarely goes above 90, unless im queuing up for santa pod lol.
Pete so ur saying a well maintained full blend is just as good as a g45 from maxrpm? Maybe a bit more boost from the 45 but not alot?
I guess u could pull it apart a port it more but u wouldn't really want to after spending £800 on it lol
I think ill keep with my full blend and see how it goes can always change another time if I get bored one weekend ;D

Could you not just use that adapter and use an extended pipe from the regular oil breather system at the back of the block on a G40?
The only other issue with the G60 is where the oil feed / return is positioned, from what I remember it's not ideally placed when its on the PY block to G60 charger mount and adapter.
If you want big power from a G-Lader its got to be either G60 with a 68mm toothed setup or a G45 on a 65mm toothed.
I think reliability knowledge has come on leaps and bounds compared to the old PSD days, things where experimented, disasters happened and now we know whats good / bad.
My dream is to have a PY block with a G60 lader. It'd be so sweet.
All sound fun but do u think the box would handle it? And what People say g60s don't like the faster revving 1.3 and smaller pulleys but I guess know one has tried it so No one can say really I think it would work both a g60 and 45 obviously more power from the 60 but the 45 if u can get good boost from it then I think u could see 200 maybe a tad more g60 210+?

Remember it has a G60 scroll inside it though which will aid to a bigger increase of airflow. The outlet only has 3 fins as well.

There are a few who have tried it. Fella from portugal has done it, few from germany and im sure there have been 2 people from uk that have done it as well.
68mm pulley is a good size for the G60. Almost everyone runs that size.
G45 would make i reckon between 190-200bhp and G60 would make between 210-220bhp.
G75 is where its at lol.

Saying you'd want to give them some well ported 40 casings to ensurr you got best ported g45 back
There must be a reason they done port it on the fancy system when they make then
Yh I know they had a g60 scroll but just didnt sound like that much of a increase but I guess it is,
It not full size g60 scroll tho they have shortened it haven't they?, yh take material from the g40 casing to make it wider inside and take material from the g60 scroll so it fits and machine grooves back in the scroll for the sealing strips. Something to think about because I'm gonna be running a Bvh, 51mm tb, gt inlet, bigger fmic, 1341 bottom end witch all make the boost pressure drop so chucking the g45 on there will bringing it back up again. 5psi more sounds nice!
Yeah but for that money you could buy a good ported g60 charger and the brackets
How much boost does the g60 produce with a 70mm pulley? That way there isnt nearly as much stress on the charger, but still making more than a g45
Yh I guess ur right lol ill stick with my full blend for the moment :) can always do it another time,
Ur still looking at £1000 worth of parts, I've just been told that apartment they are makeing g60s again at vw!
They are making g60's at vw? Why? How? If thats true, i want one!
The vw specialist I work next to told me but he said there at over £2000!
Why are they remaking them? I cant see them selling very many at that price. For £2k you could fit a heavily modified 1.8t engine to your g60 rado or golf
you could get a g75 charger for that
Only saying what I've Been told ask them!
Probably NOS G60 laders, I highly doubt VW have set up a manufacturing line to support a production run in the hundreds, especially when most boosting systems are now supplier based, not OEM.
Jezza- what are you hoping to achieve with breather system mods? If you want the BRV open to atmosphere, and still want oil to lubricate the charger, then remove the pipe from the BRV and stick a filter on it, charger will have fresh air, and still evacuate the crankcase of oil vapour. Moisture presence isn't a problem, things coated in oil tend not to oxidise easily.
G45 seems expensive and pointless to me, G60 with a larger pulley seems more sensible. Gearbox is ultimately the limiting factor to any high powered option though.
Just to lubricate the charger properly instead of ptfe stuff.
I did think about just modding a metal pipe and connecting it to the inlet filter of the charger with the breather hose going into that.
With the boost return pipe still as standard fitment, when the BRV is closed, the charger will suck from the crankcase right? So if i took my current 25mm breather hose off my catch tank and then routed it to feed the blanked side of the charger it should suck the same?
Yeah G60 is deffo a better option than G45. More fun as well i bet.
I think ill see how people get on with it. but I'm sure I will be using a g60 one day

It is a shame the gearbox is the limiting factor, I don't know a huge amount about gearboxes but surely there is an alternative we could use?

the search feature isnt very good anyway. if you search " how to fit an eaton charger" it searches for those words in seperate paragraphs rather than the title. so you get a for sale add that says. " i thought about fitting an eaton charger. but couldnt get the brackets to fit it" lol
i read a post of club polo about gearboxes, it was a long old thread, and there was no real outcome. golf gearboxes are too much of a pain to fit and dont offer any superior strengths, other polo boxes that fit dont use stronger parts. the only option was the s1600 boxes, which are mega strong built for the race cars
but obviously they are insanly rare and cost more than jezza's g60
the dutch must have overcome this problem as they all seem to run 400hp g75 16v 1.5 1w engines
Did you know that the G75 charger has almost double the amount of airflow compared to a G40 charger. Its 1060 ccm3 per revolution and G40 is 566ccm³ per rotation. They reckon a G65 charger would gain 0.3-0.4 bar boost pressure, imagine what the G75 increase is. G75 polo....... would be like having 2 supercharger on it lol

wow! thats amazing! interesting info :)
that must be so efficient! if a proper company in these modern days of technology put some real hard expensive R&D into the g75 they could make a dam weapon!
are those figures with standard pulley? what is standard for a g75? imagine a 55mm pulley on it lol, probably suck the air intake inside itself
If you go G60 then you need to get this:

Standard G60 is 860ccm3 per revolution. To jump 200ccm3 with G75 is quite a lot imo
Not sure on pulley size but i remember someone saying that they did them all on standard pulleys.
Just read that the G75 was 80mm pulley.
That looks insane! not a bad price for the fabrication involved. is basically a plenum chamber? how would a charged vehicle benefit from it? genuine question as ive only ever seen them on N/A cars. and what is the throttle off?
i can imagine a g75 with anything smaller than standard being pretty unstable tbh. i wonder what scroll bearing they use. cant be a normal one, would wear out pretty fast! normal scrolls are magnesium alloy, i wonder if the g75 is just alloy, meaning heavier/ more load on the scroll bearing
too many questions
That inlet manifold is designed to take a G60 throttle body on a G40 engine. The G60 throttle bodies are quite bigger.
This is what i was reading from the website: http://www.roettele-racing.de/shop/themes/kategorie/detail.php?artikelid=52&kategorieid=24&source=1&refertype=9
This G75 charger is already in production. This loader can be fitted without modifications to the G60 . Additionally, we have incorporated our experience with the RS G65 loader . Software of the engine control is being considered and is mandatory.
The technology:
The loader is widened by 15 mm on each side , this is accomplished by new housing halves , which has the result that the primary and secondary shafts have to be manufactured with extra length , more counterweight. The loader attachment points in the engine compartment remain original . There will be two different fuel injection intake tract , once a for motorsports with over size between 100 mm and 120 mm for the airbox. Normal for the air filter connection and The displacer is of course also widened on both sides by 15 mm , the Dichtleistennut is extended to the maximum and the displacer is modified or streamlined in the outlet area . The calculated weight of the displacer is 1050 g, and thus has a maximum speed of 15,500 loader U / min, over bearing damage can be expected. Performance and boost growth , we have calculated only theoretically and remain our secret yet , but if it is clear it will be enough . Wait and see .
We are very excited about the first test kilometers , it is of course reported it.
Throughput calculation :
G40 : 566ccm3 per revolution
G60 : 860ccm3 per revolution
G75 calculated : 1060ccm3 per revolution (However, without taking into account the extended sub-channels , is based on only the enlargement of the chambers to 75mm)
So ever makes about 23 % more throughput than the G60 . The impact of the secondary air ducts we'll see.
News for G75
The speed tests are completed, we have really made the G75 with 16.770Umin on the dynamometer to the limit. Collides with the wall of the displacer is not but still . We are currently building a 6PK 160mm crankshaft , where we can already achieve 16.500Umin and the belt slips no longer guaranteed by a 80mm Pulley . We are currently building a very large boost pressure test system for our Yellow Polo, then the speed and performance tests shall be continued. We are only happy times and go with this charger in the long-term test . This loader we build into a Corrado 8V, so we get sometimes comparative data on the G60 and G65 charger.
Cheers for posting :) love reading stuff like that, its good to hear there is development in the Gladers and polos still :) must cost serious amounts to make that
yeah i was looking at pictures and noticed the extra channels, they should add alot of boost
the stuff they sell on the website is awesome!! theyve put lots of money into developing parts for a fairly niche market
cool though
i see, so that manifold and g60 throttle body would be the step up from 51mm throttle
check this out ryan

looks dam good, pretty good price too
james so dose the tb do on the end of the plenum?
and taylor stop becuse u will make me skint lol ::)
we need to sort out the gearbox thing then g60 all the way ;)
dw James just looked at more of the pics lol
surely u don't need to have it, but lots more power if u do?
this website is amazing!!
they do a chip for the g60 conversion too!
Never been on there website seriously cool stuff! Theyve got uprated charger seals for €100
Haha ryan your falling for the temptation, all those parts so easiely accessible :P
Also the g75 uses an 80mm pulley, imagine it with 55mm
Must be a reason why they run a 80mm pulley running anything smaller probibly wouldn't do it any good!
Yeah too much load on the scroll bearing, wider the scroll walls the heavier and more load on the scroll bearing. Thats why g40 chargers done mind high revving compared to a g60. So a g75 with its all alloy scroll would weigh a tonn and anything smaller than an 80mm pulley would be too fast, too much stress on the bearing

Anything smaller will cause it to run a too high rpm causing bearing failure.
ryan what you mean by this?

Don't worry i've worked it out, i was being stupid ha
