What is the percentage of our drivetrain loss?
 

Got the iphone dyno program and it needs a percent for drivetrain loss.

I would guess 25-28%.

Def. report back - I don't have / don't plan on an iPhone but that program is dayum intriguing! Kewl

Niether did I but if you unlock it, you can skip all the at&t BS charges
 

I'll definitely report back, now to think of a good road to go 0-60 on. Supposedly it can tell you the wheel horse power as well.

Surprisingly, finding ^road/opportunity^ can be more challenging than you'd thunk - I've got...
 

...an AC-22 accelerometer (think "G-Tech" but better) and used it a good bit over the years in me various junkerz and seeking out good REPEATABLE spots can prove to be quite the chore (read: good luck trying not to attract 'attention').

Good stuff tho - I'm not one for the latest technowizardry but soon as I heard of such programming for the iPhone I was admittedly quite intrigued.

How cool!

Looking forward to your results, PenisHead 8-).

On that note, what is the best way (fastest, quickest) to launch an A8?

"etc."... like dyno Tappin' Dat A$$? Dare ya.

Thanks, will try.

That works VVVV but the best way is to rev it to 4000 and dump the clutch :)

that would be 26.2% loss
