Title: 154bhp upgrade???
Post by: AdzCM on March 27, 2010, 04:07:35 pm
hey, just found this on the net and was wondering if its legit to get 154bhp from the standard g40 with just this?

cant see why not, probibly be the extreme end of the power for that spec though so i wouldnt expect a certain 154.

doubt it,  I reckon 150bhp would be max dependant on additional mods.

Depends on what the cam spec is.  Also you'd need a 2 1/4" exhaust system, if keeping airbox then drill it and also it would depend on your supercharger spec aswell.

I used to find that the stock exhaust would sufficate itself at around 145bhp.

Cam is 252°/276°

Better off getting plugs from GSF and getting them cheaper then getting a decent induction kit rather than the filter. Might see 154 then. The cam is the most money.

Jabba's chip and pulley is around same price as well so it would be better off getting that from jabba. Or getting a chip from andy to suit the mods which would be cheaper. You could get a smaller pulley off someone from here no doubt.

If you look at this and but it individually you could save yourself money.

And the plugs are W4DPO not W5DPO which are standard ones. GSF do them for something like £10 a plug.

That kit is £450.02

Cams are around £230

Plugs are £10.50 each ( £42 )

Jabba pulley and chip £170 i think

and then a good induction kit which could cost anything

That comes to £442 but if you get a chip from andy ( Map # G40002) which would cost £30 and pulleys wont cost alot. You can get ally ones from http://www.g-laderseite.de/eshop/product_info.php?products_id=52 for £44.

Getting the cam, W5DPO plugs, chip from andy, pulley from that site would cost £342 saving £108.

That means you have £108 to spend on an induction kit.

Have a think and look around.

hmm yeah didn't spot the plugs were the colder ones.  No need for them unless big power.  stay with W5.

I think a jabba G60 induction kit 'was' about £60, plus twenty odd quid for the collar and 3" piping  -stick it where the charcoal canister used to live (if youve binned it)

unreal, you guys know what your on about and are saving me money :D

so i should get the camshaft from that site i put up then get the 65mm pulley from that site you showed me [jezza-7] + W5DPO plugs from GSF + a chip from andy + a 2.25" exhaust + a jabba g60 induction kit?

Does the exhaust have to be stainless? will i get it decat?

also, where would i get a g60 induction kit?

thanks again.

I was already planning on removing the boost return pipes so ill fit the filter where the charcoal canister 'lives' lol

Jabba should be able to supply the G60 induction kit. I can ask about them when im over there next week if needs be?
Title: Re: 154bhp upgrade???
Post by: hardchargin40 on March 27, 2010, 10:10:04 pm
you don't need specifically the G60 induction kit, I used to always have it over a G40 one for future expandibility, also liked the noise, lol.

You can just use the G40 one, slightly cheaper... I think the G40 one is actually 'flow rated' for 400bhp so Id think it'd be enough, lol.

If you were after saving money, don't have the cam just yet.  The stock G40 is very good.

Exhaust doesn't have to be Stainless, I used to have a mild steel custom made system, lighter for the track car and cheaper (cost me £220) though last you about 2-3years.  If you need to decat, then you'll need a non de cat downpipe from VAG (it was £90 years back), or cut it off the stock G40 one and get a sleeve welded over with boss welded too for lambda.

Also if, you've got a dremmel, you'd save a bunch or £'s porting your own bits. 8)

I've got a filter collar that I want to sell at the moment. I've got a filter and pipe knocking about too.

Dub diaster is selling a 2.25 system with vw decat downpipe i think. Give him a PM.

This is my induction setup, it's not jabba, just a large K&N with custom made ally inlet pipe with jabba heatshield not in pic though.

Here we go, £80 for the full system. I have seen this as antony lives about 6 miles from me.

Oh ok, its not for sale anymore lol. Cheers antony.

aw ragin :(  £80 seemed unreal.

jezza-7 .... wot diameter is that piping you used for your air filter? - does it just connect straight to the charger with a jubilee clip?
Title: Re: 154bhp upgrade???
Post by: Jezza-7 on March 28, 2010, 09:48:54 pm
If you want i will measure the filter outlet cause its a real good K&N one, and i will measure the bend. I think it cost about £15 to get made up, the black pipe is jubliee'ed on to an inlet collar which is bolted on to the charger. Will get some pics and that so you can see as well as measurements, will do it tomorrow.

That would be unreal mate, thanks, hope its not too much bother.
Title: Re: 154bhp upgrade???
Post by: Jezza-7 on March 30, 2010, 06:30:58 pm
weather was crap yesterday and today was a little better so i went out today and took it off for measurments.

These measurements are internal

Air Filter - 75mm
Alloy bend - 72mm
Rubber bend - 74mm
Inlet collar outer diameter is 75mm

So its inlet (75mm)--->Rubber bend (74mm)--->Allot bend (72mm)--->Air filter (75mm)

It all fits well and i use s/s jubliee's that are done up tight.

The bend angle's are like 90 degress but have taken sum pics to see.

No need to, i have a full blend to go on!
Title: Re: 154bhp upgrade???
Post by: AdzCM on March 31, 2010, 03:04:07 am
cheers man, thats unreal lookn ;) - where did u get the inlet collar? can you buy that heat shield separate from jabbasport? i was havin a nosey on ebay at k&n filters, n that piping shouldnt be too hard to get.

also see your on about a full blend charger - im lookn my charger rebuilt soon, would you reccommend i get a full blend? & why?

sorry about all the q's lol im learnin as i go - really appreciate the photos btw, thanks.
Title: Re: 154bhp upgrade???
Post by: Jezza-7 on March 31, 2010, 05:47:05 pm
No worries, i got my inlet collar from a mate but there really expensive if you buy them new from jabba.

I can sell you one as i have 2. Will pm you details.

I have a full blend purely for extra boost which will increase bhp as the porting of the inlet, outlet and internal parts allows more air to be sucked in and forced out throughout the air flow system but im not sure how much of a difference it would make on a standard pulley size of 75mm, but i have a PSD toothed kit to go on at the same time, and that pulley size is 65mm and will increase boost pressure.

Now i cant remember this but a 65mm pulley will spin alot quicker hence it being smaller but there is a figure for how fast then spins depending what the engine revs are. Will try find it.

The heatshield shoul be easy to get hold of. I think there £20 from jabba, give them a call and ask to speak to brian and ask him.

A little bit more info

Stock supercharger pulley is 75mm so 65mm one makes it spin 75/65 times faster. Normal peak pressure is about 1.7 bar absolute (i.e. 0.7 bar boost above atmospheric pressure) so the smaller pulley gives you about 1.7 x 75 / 65 = 1.96 bar absolute or around 1 bar of boost. Get a boost gauge if you haven't got one and you should see 1 bar as you get close to the red line if everythink is working OK. The 65mm pulley is about the smallest you want to go. A small pulley makes more difference to tuning a G40 than anything else and will increase torque across the whole rev range rather than just peak power.

thanks again mate - that toothed kit is pretty expensive - u get a psd kit?

im looking to put serious money/time into my G now that i just sold my corolla :D

pm'd u btw ;)
Title: Re: 154bhp upgrade???
Post by: Jezza-7 on March 31, 2010, 07:20:03 pm
Yeah i got a PSD kit. I paid £200 for mine.

Someone is selling a kit that is a PSD replica which i think would be ok. All the same at the end of the day.
