vr6 throttle bodies

hello all im new to the site and to vw owner ship what i was wondering is if any one knows what kind of gains i could expect to get from fitting throttle bodies on a 2.8 vrg or is it better to go the turbo route ???

hhhmm let me think about this...

throttle body......turbo........throttle body....turbo..throttle body......turbo........throttle body......turbo........throttle body......turbo....
















































i think perhaps a turbo?

 

yea i know i love turbo's aswell but why would it be better if better at all ?

 

cos a turbo would equal 350bhp

 

under more pressure thought and more chance of poping it

 

I'd expect more from throttle bodies than a throttle body

 

edc1 what was that

 

Pinch

 

I'm guessing what you want is throttle bodies as opposed to a throttle body. If the search is working have a quick go cos soebody on this board has a VR6 on bodies done by Grant Motorsport (?)

 

ok will look and see i can get a turbo kit for it for about 1500 from the usa thats the chip front mounted intercooler oil cooler pretty much every thingthats all im thinking about

 

They don't do much on an internally stock 16v - I don't know about a VR6, but i reckon the same princple applies: You fit them so the engine can breath better and it only needs to breath better if it can induce more air = big cams and headwork

 

Say no more



This is Anthony Dowd's "All motor" (what the Americans call a normally aspirated engine) VR6. It's the quickest NA mk3 VR6 in the world, he's just run an 11.77 1/4 mile. 223BHP at the wheels, and it's still a 2.8 bottom end with well over 100K on the clock....just wait till he goes to a high compression 3.1...it'll be into the 10's. There's already a 2.0 20v corrado on ITB's running in the 10's over there.

Not made by Jenvey then... SF bodies on fab'd inlet manifold block with different length air horns..

 

I'm guessing that vr6 has had a lot spent on the head though? As I understand things the vr6 head is slightly flawed due to its tight packaging, meaning that the flow isnt all that great. this being the reason it responds so well to turbocharging - the turbo effectively reduces the effect of the flow problems as well as providing boost.

 

yes, they are jenvey units, but the manifold and the rest of the setup is Grant Motorsport.

Just like your "badger5" throttle bodies are just Jenvey units.

 

ITB's for noise, throttle responce and true driving fun!!! Turbos have been done to death, N/A power is the way forward for me. I'd go for a 3.1 litre on ITB's if you have the money. Drop Grant a mail at grantley@grantmotorsport.com I'm sure he will sort you a nice road set-up. Anthony's is for race use but shorter trumpets and different engine mounts can keep everything inside your bonnet.

 

Is that the car that was in teh PVW shootout a couple of months back?

 

yes, look out for a full feature next month.

 

Okay - Whats does one do to get one of those 24V units into a MKIII?

 

throttle bodies a lot of money for not really huge power gains, where they do score is in throttle response and drivability. They will only really help if the rest of the engine is built to a high spec, so needs cams over 260 duration and a really good head porting job.

starting with a 24v will give better gains, and the head is already good, so just cams to buy

Although a turbo will make way more power, you have to decide if you can live with the poor throttle response and lag.
