these are now available. :o http://www.maxrpm.de/RS-G45-Lader-convertion-with-RS-modification-G45-supercharger
You supply a pair of decent g40 casings, together with a fecked g60 scroll (only fecked where the apex seals go) they machine the casings 2.5mm deeper each and machine the g60 scroll from 60mm to 45mm. They then port it and fit new bearings/apex seals/oil seals.
If anyone fancies one, PPP and I both have a trade account so can probs sort you one out a little bit cheaper.
-
Pete- I'm just about to put an order in for more stock, so if anyone does want parts then give me a shout, ill be next week when I send payment.
-
ooooohhhhhh.............. I'm seriously tempted by this. Not sure if it's worth sacrificing my std or full blend.......or whether it'd be worth getting another one to split.
Anyone selling any casings and a G60 scroll? ;D
-
How much does all this cost and what are the gains? Do they make much more boost ?
-
The info is in the link.
-
The flow of air is shown for a G40 and a G45, anyone know if that's a standard charger with standard pulley or what spec its referring to?
Also, what's the smallest pulley that would work safely (would it still be 65mm?).
It'd be good to get like-for like comparisons on;
1. Standard pulley & charger
2. Standard pulley & Full blend (equivalent)
3. 65mm pulley & std Charger
4. 65mm pulley & full blend
5. std pulley & G45 charger
6. 65mm pulley & G45 charger (or equivalent max. "safe" pulley).
I'd expect it'd be ideal as a G45 with 65mm but if it can't do that then it might equate to be the same as a standard G60 bolted on. The torque would increase I suppose, having more air rammed through the engine at lower RPM, probably make it spin up even more on the move too ;D

Flow of air is quoted as per revolution, so pulley size doesn't enter the equation. I like your thinking though - how much of a difference would this make compared to a well ported G40 charger and how much porting you could get away with on a G45 remains to be seen.
-
g45 can have same porting as g40. quoted roughly 0.15 bar extra boost. So if 65mm with g40 ported is 1 bar - therefore 1.15 bar g45.
Id also say not to go under a 65mm pulley.
-
Hello Pete,
the G45 is based on the normal G40. The external look is completely the same.
About the extra boost of +0,15 Bar: The increase of the extra boost we have measured with a series pulley. With a smaller pulley, the extra boost can be a little bit more in compare with the normal G40 charger.
Many greetings,
Thorsten

I have just been looking into these and i would like to get one of these but im not sure on it. Would you be able to send out say an R1 charger casings and the scroll? Im not sure if its worth the money. By the time you get the casings and the scroll that might be a few ££ then €700 later. Could easily spend £800 on just the charger for a small gain. Would be easier to just get a G60 lader surely?
-
stock casings and a g60 scroll(which can have some damage). they service and port etc.
roettelle racing do them... they have more details of g65/70 on their website.
-
Hello Jezza-7,
at my last posting, I made a little error about the boost pressure.
The extra boost with the G45 is ca. +0,45.
Many greetings,
Thorsten

Ah thats good to know.
Thorsetn, how much is a G65 charger to buy complete from you?

I really fucking hope he is
-
Yeah gonna look into it :o
Prob gonna do it at the end of the year though as i want to drive the car through the summer this year, unlike last year. And nerburg pencilled in for may.
-
best thing to do is to look out for a used, slightly damaged (apex seal ends) g60 scroll on dubforce or something. (or german ebay) Should be pretty cheap... then casings are easier to come by - or use a g40 charger and sell the scroll.
if you want big powers g60 chargers can be affordable, Was a stage 4 with 5,000 miles since rebuilt on ebay for £400 last week,
-
Hello Jezza-7,
the price for a complete G65 is 1649,99 EUR + 21,- EUR for shipping.
The price is incl. all parts (G65 racing displacer, case parts, all wearing parts, ...).
More infos, you can see here: http://www.maxrpm.de/RS-G65-Supercharger-convertion-complete (http://www.maxrpm.de/RS-G65-Supercharger-convertion-complete)
Many greetings,
Thorsten

Cheers for that Thorsten!
Do you make a complete kit for the fitting to a G40? Like the bracket and a toothed belt kit?
Woukd you recommend fitting a standalone oil kit for the bearings in the lader?
-
Hello,
we do not have a kit with all the parts, you will need to covert to a G60-charger. But most of the parts, we have in our onlineshop like the bracket and the 5PK-conversion kit. Likewise, we have a toothed belt kit, but it's a little bit more expensive.
Sorry about, but please can you explain, what you mean with "standalone oil kit".
Ciao, Thorsten
-
Oh ok i will have a look for them.
It is a separate oil supply for the bearings in the charger. Instead of putting the engine oil through the charger we/some people use a kit that puts better quality oils, that wont be as dirty as the engine oil, through the charger. This helps the charger bearings by giving them a longer life and the tempreature does not get as hot.
When you did the testing did you just use the standard oil lines from the engine?
Many thanks.
-
Cant seem to find the belt conversion kit. How much is the 5pk one and the toothed kit?
With the bracket, would you have to change the tensioner pulley for a toothed one if you went to a toothed belt kit? If so, how much would that cost?
Thanks
James

Hello,
thanks, I understand. This is interesting, but I see no need in it, because:
1) When using fully synthetic oil, you have the best conditions for a good lubrication; even at high temperatures.
2) When you change regularly the bearings (for example all 60tkm or every 2-3 years), you will not get any problems with the bearings.

Thankyou very much for that.
So for the charger it is 1649,99 EUR
For the bracket it is 85.00 EUR
For the toothed kit 229.00 EUR
All together i would be looking at 1963.99 EUR
I would also need the spacer as well for the toothed kit, remember seeing something about that in the description. Could i not use my toothed kit i currently run with the spacer?
Would i need anything else? I know i would have to get a front mount intercooler and all the pipe work plus a remap.
Trying to see if i can afford it as this will be a project at the end september over the winter.
Thanks again Thorsten

Hello James,
when using a G60 with the toothed kit, you need a some "bigger" spacer. When you order the parts, please remember me. There are no more costs because of the "bigger" spacer.
What you still need is a MAP-sensor (pressure sensor), which have a bigger measuring range (http://www.maxrpm.de/Boost-pressure-sensor-250-kPa-15-Bar-MAP-Sensor (http://www.maxrpm.de/Boost-pressure-sensor-250-kPa-15-Bar-MAP-Sensor)) and a modified tuningchip for the G65-charger.
A fitting tuningchip for the G65-charger, we don't have in our onlineshop. But when you give us a list with all the changes on your engine (for example when you still have a tuning camshaft, modificated cylinder head, ...), we can offer a fitting tuningchip for 150,- EUR.
Or as a option it would be perfect, when you can drive to a local dyno next to you to make a optimum engine/software setup.
When the time is there, that you will start your project, please mail us. We will make you a offer for all the parts.
Many greetings,
Thorsten

Thorsten,
Thanks for the information.
Do you sell fully ported G60 chargers? Been looking into the cost of it all and the G65 charger might be the thing i would struggle to buy.
James
-
Hello James,
sorry, when I must ask again, what do you mean with "fully ported". When I understand you write, all G65-chargers are ported (modificated) G60-chargers.
The G65-charger is not a brand new charger. But after all the modifications, it's "like new".
Ciao, Thorsten
-
Sorry, the "fully ported" is pretty much similar to the way you port the G60 charger but not as ported to make it a G65 charger. If that makes sense?
-
gah, the options are endless. I'm glad I've run out of money for power mods or I'd be seriously looking at getting one.
Thorsten; I think it would be of great benefit to you and your customers if you could create a table of power outputs/ flow rates for the various charger levels. It would give customers a quick idea of what sort of difference they could expect and if it's worth doing or not.
-
Hello,
no problem, here is the table with the airflow:
- G40: 566ccm³ per rotation
- G45: 635ccm³ per rotation
- G60: 860ccm³ per rotation
- G65: 925ccm³ per rotation
- G75: 1060ccm³ per rotation
Ciao, Thorsten
-
By the way, the G76 is not still available. I calculate the end of this year for availability.
-
Hi Thorsten,
I have a few questions as I am quite interested in a G45 charger.
If I bought your RS2 conversion (which you rate at 166PSI with a optimized/ported G40 charger)
and fitted a G45 charger, what power gain's should be expected?
Would the MAP sensor/boost sensor need replacing?
Thanks
Mark
-
Good morning Mark,
a normal G40-charger has ca. 0,5-0,6 Bar with a series pulley. The G45 have ca. 0,9 (+/-) bar.
I don't think, that you get a boost pressure more than 1,0 bar. Until 1,0 bar, the series MAP sensor works. (Thank you Andy for your correction!)
My advise ist, that at first you still use your series MAP sensor. After all modifications are made (on your car/engine), you should check your max. boost pressure.
By the way, the boost pressure is not only depending from the G-charger. Modifications like a tuning cam shaft or a cylinder capacity expansion (not to mention a leak in the boost pressure loop) could be could be result in a more less boost pressure.
Ciao, Thorsten
-
Stock MAP sensor is only rated to 1.0 bar (or 200kPa absolute), so if you're running more boost than that then you need to consider fitting a 250kPa/1.5 bar rated item.
-
Hi Thorsten,
Have you tested the G45 charger on your RS2 conversion?
Are you able to post up engine dyno or rolling road output figures from your standard RS2 conversion and then a comparison with a G45 charger fitted?
It would then highlight the advantages that the charger makes to the identical spec and car.
I am aware that different engine spec's will lower boost figures due to the engine working more efficiently.
Currently my G40 is running a ported G40 charger / 65mm tooth belt conversion / GT inlet manifold / de-wegded throttle body / chip and I see 12psi boost (on a budget boost gauge).
Thanks
Mark

Hello Mark,
no, I don't tested it with our RS2 conversion kit.
Many greetings,
Thorsten
