lost 58hp going a4. Just got the car back with the m6 to a4 conversion. Only put down 370 compared to 428 with the m6. This was with an unlocked converter and a 4000 yank stall. Does this seem right. What would have done locked??

Is it the same dyno and are both numbers corrected to SAE?
It could well be right, but there's likely to be some varience anyhow. Even without any changes you could easily have seen 10rwhp variance in numbers.
Also you haven't lost any HP at all. The engine is just as powerful, dirvetrain loss has increased but it's being used differently. Aftermarket stalls are not as efficent as stock ones, and being unlocked I can well believe the numbers are not far off.

Check out the numbers in my sig. Our setups are similar only I have an auto and I put down 409 HP LOCKED. Unlocked I could only guess how low, maybe 380, 385. Auto cars usually post locked numbers because thats how we tune them, locked. Maybe locked you'd dyno around 395, 400.
Also on another note, you might consider also that locked A4 #'s compared to a same setup M6 #'s are roughly 20-25 HP less. Hope this helps.

Im not really to concerned about these numbers. Im a believer that the auto do better at the track and thats all im really concered about. Just thought i would share my results. It was on the same dyno. Its funny to see the faces on people when they ask me if i put an auto in to make more power and i tell them i lost almost 60 horse. They are so confused. The stall is a blast to drive and i cant wait to hit the track on saturday.

A few years ago we had an LT1 Turbo w/6 spd, had approx 575HP, went to high stall auto, had approx 474HP on our Mustang Dyno. However, his "force" pulling on the dyno straps increased approx 400 Lbs at given MPHs due to the drivetrain's TQ multiplication at the rear axle due to the higher stall.
JOHN563-i know what happens when the light turns green when i'm against an auto.....i usually win. in fact i cant remember my last loss,it's been two years or so. i out 60 foot almost every a4 i'm against,my best so far is a 1.34.
