Very different from car to car, but new Porsche drivelines are very effective. I believe around 8% for gt3 and 13-15% for turbo awd is pretty close. So a rwd turbo would be better than an awd turbo but not quite as good as the gt3 driveline which is remarkably good...

12.5% for RWD and 18.5% for AWD in these cars. Thus, that car is making right around 800 crank HP.

Oh, that's a Tip? That's what I get for skimming posts.
Ya, 12.5% and 18.5% are for manuals. Add another 5% loss to both for tips.

more like divide by .90 or .85 (or whatever you find the accurate number to be).

Incredible power and performance!
KeithA, please keep us updated on your car and how it compares to Chris Green's.
(didnt he outrun your car, although you had major problems?).
If that dyno was done at Protomotives shop (same dyno as mine was done on), here
is my OPINION;
my dyno was 628 RWHP (75 less than this car),
my car is very, very, very close to all performance figures known for the RUF RT12 650,
so I believe I have very close to 650-660 CRANK hp.
628 divided by .95 = 661 crank hp (my car on Todd's dynapack dyno)
703 divided by .95 == 740 crank hp for this 997 Turbo (I have not factored anything
for the tiptronic and do not know how it relates).
I would think 740-770 crank hp would be REALISTIC.
IMHO
