What Does Your 4.0 litre Chim Make?
Discussion
Hi folks,
I have been running a post over in the Wedge enclosure trying to establish who has the most powerful normally aspirated 4.0 litre Rover V8 powered car.

This has proved to be an excellent source for my favourite hobby "Wedge Bating"
After a lot of cheating, the best genuine 4.0 litre Wedge currently weighs in at 255hp.
MegaSkirts & other after market ECU's are fine but no laughing gas, blowers or 4.6 litre cars with a 4.0 plenum badge please.
So come on, lets show the Wedgies who's boss.
NB: Early 4.0 litre Grifters are also welcome

Mine made 245hp on Joo's rollers running hotwire (Castle Race Engines chip), bulleted bronze guides (but no other head work), trumpets shortened by 25mm and a Typhoon cam with Rhodes lifters.
Forget exact the torque values but from memory it peaked around 270lb ft and pulled around 250lbft for alot of the rev range, obviously dropping a bit as it reached the top end.

Iain

My standard (except pre cat removal) 4l makes 226bhp. 63k miles and well looked after!
I'd be interested to see dyno runs from people with filters/induction mods/trumpets to see if it's worth the outlay?

It would seem that if that 226bhp is accurate you are doing well as you are and I doubt any small gains would be worth the outlay.I'd be interested to see dyno runs from people with filters/induction mods/trumpets to see if it's worth the outlay?

Come on boys, we can do better than this.
The Wedgies are mocking us.
Sadly I only have 233hp myself, but surely there must me some top performing 4.0 litre Chimps out there to beat the Wedge best of 255?
Nothing I've seen so far on their thread comes even close to my 400's output .........The Wedgies are mocking us.

if only you hadn't banned blowers .......

This kinda supports my theory that peeps who buy Chimaera 400's are more interested in looks and noise (and perhaps posing) than BHP and performance
I suspect most people buying a TVR will have an interest in performance but a lot of the numbers being churned out are just that, numbers.Two different cars on two different rolling roads means very little, add into that they may be measured on two different days weather wise and it means even less.
Take a car in, stick it on the RR, measure it, do some mods/changes/mapping etc and stick it back on, measure it again and that might actually be worth something.
Anything else is just pub talk, but entertaining nonetheless
