Ess_three has a 16v and looks to be getting high BHP without a TC or SC.

Yes this is where the nearly 200bhp figure comes from.

He has performance inlet cam, standard exhaust cam, ported and polished head, with matched inlet and exhaust. Along with the other stuff like exhaust, modified airbox, throttle body remap etc. He has shown a 46 ish bhp increase and torque of 160 lb/ft torque.

What I really want to know is if it is cheaper to get better results from the VR6. If it is I will consider the swop, how hard is it to gt 240 to 250 bhp from the VR6, or am I dreaming without boosting it.

What will a similar level of modification give on a VR6, and what are the costs.

Manifold, cams, headwork, remap, how much for how much gain.

Cheers

The vr i used to own was an OBDI. It had filter, jetex exhaust, remap, and it was running 190-195bhp.
I got the exhaust second hand, i got the chip second hand too, my father-in-law soldered a socket to my ECU, so i could interchange the chips myself.
I would say 220bhp+ would be easily achievable on an OBDII, with the above work and a good set of cams.
The VSR won't add any bhp, it just drastically increases low end torque, like a real V6.

Yes Glen has put a lot of time and research into the mods on his 16v and backed the modifications up with RR results, dumping the rubbish ones and keeping the good stuff.
It will be interesting to see the results he gets with his ITB's and revised cam work.

Variable Inlet Manifold. The manifold varies the length of inlet tracts to boost low end torque.

Is this the item made by Schrick (spelling)

Will look at these figures and analise the BHP to Weight ratio of both cars. And then look some more into the costs involved.

I'll post up an analysis of costs when I've worked them out.

Thanks for the info.

Yes, the variable inlet manifold is made by schrick.

Was very expensive new but makes one hell of a difference.

My old vr made 191.4 bhp at Awesome last year, that was with a 6 branch manifold, induction kit, decat and stainless exhaust. Would deffo say that 200bhp could have been achieved with a remap.

I'd say that spending £1500 on your vr would get you 220-230bhp with bucket loads of torque.

Just my 2p's worth - any VR6 will need a small refinery to fuel it, especially if you like the loud pedal  :evil:


Keeping schtum. Mostly.

A heavily tuned 16v will also drink fuel  :rolleyes:

If a 16v and a vr had the same bhp the vr will always drink more fuel.
