hi i have heard alot of talk about people saying "shud i supercharge or throttle body my v6" so i am wondering if anyone has gone down the throttle body route?
i am genuinely saving up for throttle bodies but was wondering if its worth doing it!?
any advice??
wot management do u run??
cheers

I don't think there is much gain there TBH. Probably putting on 3.2 exhaust manifolds (modifying the better 3.0l cats) would be more beneficial first

Throttle bodies will probablty help a lot but you will loose low down torque so not so ideal for something the weight of an Omega

And the cost of fitting them will easily buy you two superb Omegas.
The only justifiable reason I can think of for fitting them is on a race car. Which is pretty unlikely!

Actualy a kit car or transplant to a lighter vehicle would make sense

Yep, if going for maximum breathing at high revs at the expense of torque at low revs they are ideal, otherwise, certainly not. Probably not something you'd ever want on a heavy car like an Omega, but perhaps if transplanting into a kit car. Jenvey bodies are also not cheap. I'd be having a go with some motorbike throttle bodies instead if on a budget.

I would only consider them after a decent amount of tuning - porting, hotter cams, etc. as the induction setup doesn't seem to be the weakest link on a standard engine anyway.

It would also be pointless to use them with a MAF, so you'd need to have changed to an aftermarket mappable engine management setup first.

There was a guy on vectra forum who fitted jenvey throttle bodies to his gsi with good results, but need custom mapping eg omex etc.

Jenvey were proving their throttle body and trumpet design on an omega v6 when the guy in question had been to see jenvey.

Jenvey definitely know their onions, but prepare to spend a good amount of money, especially afterwards for outlay for stand alone ecu and custom mapping, I think you will find the regular MAF won't cope with airflow, resulting in use of a MAP sensor taking readings from the inlet manifold area.

Jenvey will put you right.

nice one cheers for the input guys. i am lookin to gain more power but unsure which route to take. but to be honest once ive got the cash i will probably just buy something else! i love the omega but to develop i need more grunt

There will be no point in fitting Jenveys only to strangle them by ducting the intakes through a MAF. You need a speed density or alpha-N injection setup with them, hence an aftermarket ECU.

To be Frank, there's probably a good bit of serious tuning you'd need to do on a V6 before Jenveys give you any gains at all, and very few people have trod that path, so there's precious little information that will help you. Unless you're feeling particularly adventurous, I'd start with an engine with a bit more tuning pedigree, myself.
