Re: Build update - almost there
If it's a manual transmission, then approx. 25% loss is more likely. With an automatic it's 30-35%, depending on the box.
This would mean around 337 bhp at the flywheel.....
I'm very interested in the specs of your "ol' RV8" A friend of mine got some 220 bhp at the wheels with a 4.6, 285 cam and 4 double 45 dell'ortos..... and mine is doing less than that, although it is in very good condition. Perhaps my new setup will improve this; LPG injection, 72mm throttle body, 45 mm trumpets, ported itake, 234 cam. (I already have stage II heads and 45 mm headers....)All planned for next autumn/winter, didn't have the time to install before the beginning of this season.... (I don't drive in the winter season anymore since I ruined a set of wheels due to the amount of salt they use on the road here....)
Very impressive result, I hope to get near!
1989 Dax Mk III, TVR 4.6 V8 with Merlin F85 heads on LPG.
After 17 years, I'm still not bored!
