Thanks man! Remember that this is to
ALL 4 WHEELS!
Had we actually made this run on Monday for the shootout we would have had the highest horsepower car in the field.
Oh well!

that 1.32 dont make sense though....I ask because a level 4 aka 600 flywheel HP only does circa 500 RWHP...If you multiply 500 by 1.32 you get over 650 not 600!!

hm...not sure...
if there is a lost of 20% hp due to awd...
don't we just divide the number 586.7hp by 0.8?
586.7/0.8 = 733.375
that's roughly around 733.375hp...
733.375 X 0.8 (20% loss) = 586.7 (if you like to see it ther other way around)
And as for Stage 4 GTR (568.2hp)
that's equivalent to 710.25hp (if 20%)

Based on the information I have a stock 996tt records 320 hp on the GIAC dyno. At 32% that means it produces 471 at the crank. 
Come on guys, it's getting a little deep.

Please explain your math.
I see this:
320 x 1.32 = 422
Pretty close to 415.

Hi Jeff,
I know little to nothing about the Mustang awd dyno. I called two people who had them. One said 25% loss, the other said 23% loss. I did the math like I do it for a 2wd dyno. Take 415 and divide it by .77 (1.00-.23=.77) and you get 415.
Using the same method 320 divided by .68 (1.00-.32=.68) equals 471.
Actually, I am use to seeing the dyno sheet state the standard used to determine the rwhp. It was no where on the sheet. I believe we need that information to go any further. I really don't believe any dyno numbers can be compared unless they are the same type dyno using the same standards. You also need to be using the same gear to compare. Fifth gear will yield higher numbers than fourth gear on the 996tt. The standard for comparison on the same type dyno's must be SAE 1349J June 1990 rev. That way all tests on the same type dyno can be compared regardless of ambient temperature, pressure or humidity. Unless you are using an engine dyno, crank hp is really a guess. Even engine dyno's vary if the engines is not tested with all the same equipment attached. That is to say water pump, alternater etc.
In addition, Porsche rates their power at BHP not SAE. You need to deduct about 1% from BHP to compare to SAE. As an example 415 BHP is approx. the same as 410 SAE HP.
If you disagree please let me know.

Chad,
Exactly who knows what the real flywheel number is that is why we tested all these cars on the same dyno at the same time. Too bad your car wasn't around to compare. Who knows what my flywheel or your flywheel number really is, but my car was the highest powered car of the 9 that actually showed up.

I actually called Mustang and spoke to one of their salespeople who said it is near impossible to come up with a conversion factor to flywheel hp. But he did say it was around 23 to 25 %. Even so if you take 586 / by .75 you get 781 flywheel. or 586 / by .77 and you get 761. Either way it is an impressive number.

Duane,
Yes the RED BEAST will be spending the winter in Arizona at EVO for some additional work! Let's just say we plan to kick some tail at next years shootout! We will have all the bugs worked out by then!
