How do you dyno an A4?
People say to dyno the M6 in a certain gear (4th I think), but what do you do with an A4?
Won't the trans kick-down when you floor it? And if you don't floor it to prevent the kick-down, won't you get lower numbers?
I think I read in the manual that if you start in 2nd from a stop, the trans will start (and stay) in 2nd. Is that the gear to use with an A4?

Most A4' with 3:15 gears or higher are tested in 3rd from 65mph-150 mph.When I had the 2.73's I tested in 2nd from 80mph-120mph.Each

Guess I should have mentioned I have the 3.15s...
I hope to dyno it, add an intake, and dyno again. I'm just not sure if it's worth the cost, since the intake will only be around $250.

We did ours with Breathless Performance at the Birthday Bash. Used 3rd gear to rev. limiter, about 150 mph with the 3.15 axle ratio. The operator will tell you how he wants to run the tests.
Good Luck!

Re: How do you dyno an A4? (CliffB-99)
the key factor is puttin the transmission in the 1:1 gear.....in the A4 it is 3 and in the M6 it is 4
I have driven both on the dyno, gotta go about 70ish in the A4 then floor it ....in the m6, just mash the gas at 40 MPH
hope that helps

Re: How do you dyno an A4? (ALLTHROTTLE&NOBOTTLE)
If I remember correctly, I did 2nd once (by mistake) and the hp came out much lower. Next run, operator told me to keep it down till it shifts to 3rd and then go to redline. So 3rd is the proper gear.
