e31 head with race cam (.565" lift @ 326/315 dur, sunbelt racing)
12:1 compression, VP109 race gas......264rwhp donc 311 cv ?
"Yes, the type of dyno you use can confuse the issue as Dynojet #'s are always thought to be inflated.
As a rule of thumb with evos/subarus that are under say 500 hp the wheel horse power figure seems to be around 30% less than the power at the flywheel"
30% perdu = 377ch ?
1rwkw is equivalent to 1.341022rwhp.
KW to HP - You type in your car has 209 KW's, it tells you you've got 280.2736 Bhp.
"Converting wheel bhp to flywheel bhp and vice versa
To reflect the fact that % losses are high for low powered cars and vice versa I use the following equations which have been found to correlate well with real world transmission losses.
FWD cars - add 10 bhp to the wheel figure and divide the result by 0.9
RWD cars - add 10 bhp to the wheel figure and divide the result by 0.88
4WD cars - add 10bhp to the wheel figure and divide the result by 0.84
To estimate the expected wheel bhp from a known flywheel bhp just reverse the equations
FWD - multiply flywheel power by 0.9 and then deduct a further 10 bhp
RWD - multiply flywheel power by 0.88 and then deduct a further 10 bhp
4WD - multiply flywheel power by 0.84 and then deduct a further 10 bhp
Remember, these percentages are not "gospel" - they are good realistic averages."

Il s'agit de la voiture de Mark, un des membres de HBZ avec qui j'avais beaucoup discuté à l'époque où j'essayais de comprendre comment fonctionner les carbus Weber. C'est quelqu'un de super cool!
Il restaure d'ailleurs sa carroserie en ce moment avec de subtiles modifications (accentuations des arètes
repainting my '71 240 (carbon fiber hood/hatch)Mathieu - 72' 240z qui va bien!
