correct; wheel hp is probably closer to 210/210GTPGuy82 said:that's not at the wheels though, correct? Those are flywheel numbers.

We could only wish that drivedrain loss was only 12.5% - Based on those numbers, FWHP would probably be in the high 190s for the 6 speed and low 190s/high 180s for the automatic.carsuperfreak said:correct; wheel hp is probably closer to 210/210
I could see 15% with a fluid switch.miscreant said:We could only wish that drivedrain loss was only 12.5% - Based on those numbers, FWHP would probably be in the high 190s for the 6 speed and low 190s/high 180s for the automatic.
However, I've been "assured" that the production HP numbers are slightly deflated from actuals (several people have told me that the 3.9 was producing virtually the same curves and peaks as the global 3.6L). So I wouldn't doubt a dyno on a 6sp 3.9 would be in the 200s, but I'd bet flywheel is running about 250hp.
I think you'd see 17% on an M6 (the F40 isn't particularly special) and 20% on the A4. Saab 9-3s see about 17%, and considering they are "siblings" I think the numbers would be close. And the Grand Prixs with the 4T65E's tend to show right at 20% (mine ran 204-206 [three dynos] in stock form with quoted 260hp flywheel).Blackrider said:I could see 15% with a fluid switch.
I'm willing to compromise, I’ll settle on 17% lolmiscreant said:I think you'd see 17% on an M6 (the F40 isn't particularly special) and 20% on the A4.
