Is there an Auto Trans only dyno thread?

harshest dyno i went and got a baseline at was at AWD tuning where i got a staggering 138whp lol

highest WHP #'s aren't important, if you want to properly tune your car. run on the same dyno and try to get the best improvements on that same dyno

ive seen cars dynoed at 400whp beat other cars who dynod elsewhere at 500whp. a dyno wont tell you how fast you are or could be.

I'd rather see a smooth plot showing power gains throughout the revband than the final number. Paints a better picture of how your car is running and how good your tuner is. That and AFR.

basically power is the same up to 6k rpms, if there was more drivetrain loss in the AT it would be seen across the entire powerband

I disagree. Auto transmissions always have higher drivetrain power loss than manual transmissions and chassis dyno testing always confirms this. My car has been custom dyno tuned and the AFR holds 12.5:1 all the way to redline. With the same mods and tune MT cars are making 190-200whp on Dynojet so why is my car only making 183whp on the same dyno if not extra drivetrain power loss?

Bottom to top it's:
- OFT ESC OTS 91 Tune
- Delicious ESC Dyno validated OTS 91 Tune
- Delicious ESC Dyno validated OTS e60 Tune

ESC = Phantom Electric Supercharger in case you didn't know.
I'm hitting ~4.9 lbs of boost at 3k RPM tapering off to 2lbs of boost at 7k

Also note that this is on a mustang dyno so it translates to ~220hp/224tq at peaks (although the torque peak could be ignored since it's so short)

Wherever did you find a Mustang to Dynojet conversion factor?


Are you concerned about that massive lean spike when the e-charger kicks in?
