vr6 turbo

[twin eng, twin turbs]

Alluminium flywheel and pulleys,

Im running the standard flywheel and pulley . Why would you play around with the harmonics and balancing of the engine without really knowing its outcome

linished crank or reground if required.

Id get the crank knife edged as well

I have balanced numerous bottom ends as an engine reconditioner and though aftermarket suppliers of alloy pulleys and flywheels say they are balanced when you balance a bottom end you balance the crank first and then add the pulley, flywheel and pressure plate and rebalance them all at once because it will be out of balance! Maybe not by much, but a decent amount will effect the bearings life, put undue stress upon the engine and reduce power and the smoothness of the engine under high revs. Knife edging is a great idea to and will reduce rotational mass as well as reducing parastatic frictional losses.

can you imagine the time, effort and pain in the @$$ it would be to engineer a twin charged setup? wow. it makes me wanna go get drunk to not think about it at all.

Says it all really!

I'd go a blower myself. Love that whine!

turbo ftw.....

VR6 turbo would be a better set up i recon, not a big fan on blowers

Many people have problems with the superchargers on VR6's with slack in the belt, if it is too tight, it puts too much preasure on Power steering, alternator, water pump etc, and eats them for brekkie.
If too loose then you dont make the power, most people struggle to make over 270hp with a supercharged setup.
I have read nearly all of the threads on Vortex on this.
Easy to make power with a turbo

Also Turbo FTW

Bah, what would you know...

Put a puffer on it!

Bah, you own a turbo!

270hp in a mk3 is MORE then enough. The vr6 is a lively bastard as it is, with 100hp more it would be a real handful!!

i have to disagree with all you supercharger lovers.
VR6 is already way too slow off the mark. Youre just gonna make it worse. At least you can make a turbo car boost earlier. Only problem is the power delivery wont be as linear so u create a bit of a straight line warrior

Stuff it then. Lets rip out all the vr6 motors and chuck in 1.8t's?

thats hardly a step in the right direction! VR6 is a sweet motor. Just the 12v is impossible to get power from withough forcing it in there

This is very true.

How many of you have actually seen the VR6 port's incl. the new 24v one.

There are bloody terrible & I can see why they say it's probably one of the worse cyl. head design's in history.

But as bad as they may be, you can still force the stuff in there & it will still work.

Didn't EIP Tuning have a bolt-on kit that produce over 400hp on the stock Corrado 2.9 VR6 in the very early day's?

Bildon motorsport are currently trying to squeeze 250hp + out of a 12v NA VR6. Im not sure how close they have gotten yet but they have some interesting pics of vr6 heads cut away and such



EIP are all but gone now. They were laughed off the face of the earth after messing around so many customers. See http://eipsucks.com/

They did have some nice looking stuff. But were blown away when C2 come to the market in the US.

It's funny how some of these mob's are trying to squeeze orange juice out of apple's!!!!

VW Motorsport were getting 280+hp out of there NA 2L 16V rally engine.

I did read alittle bit about what happened to EIP. Sad & very frustrating story about what they did to some of there customer's.

I just found my old copy of a 1997 European Car with the very early EIP Tuning VR6 turbo's.

2.9L engine. Compression lowered to 9.0:1 with a thick copper headgasket, 12 psi, different Fuel pressure reg., AutoThority tune, 378hp & 419lb-ft at the wheels.

I think the idea is to squeeze what they can cos they service a lot of racing customers that have strict class rules

with regard to the tension in the charger belt, there was a guy on Vortex how is very proud that he had the first cogged vr6 supercharger pulley.

by cogged i mean it has teeth. like those massive drag racing superchargers.
so his belt never slips. he reckons the usual vr6 supercharger, if its got the pulley on it to make, say 8 psi, it might only actually make around 6.5-7psi and not all the time and where its supposed to. but his will because it can not slip.

im pretty sure he had to engineer it himself, making appropriate pulleys for power steering, aircon, and of course the charger and whatever else runs off that belt.

im not debating that turbos can easily make alot more power. hands down they can. i think all i'd really want is around 250-270hp anyway. the reason i'd like a supercharger over a turbo is cos everyone and his brother with his fully sick skyline has a turbo. i reckon blowers are more old skool. and old skool is freakin cool

i've also heard that with turbo's you lose more of the VR grr, where as with the blower you still got it.

if only i had a money tree
