Different dyno, different day, maybe different correction factor? OP's dyno used STD cf which will show bigger numbers than SAE.

yes, you will lose more power to the wheels with an auto. I believe it's roughly 15-17% loss with a manual and 18-20% loss with an auto.

Auto is more like 22-25% actually in my experience.

yea I thought I might have been a little generous with the auto %. after market trans mounts will help with this too.

Also lighter wheels. That's why I am saving for RPF1s

At least you don't have to deal with the RWD format. My buddy just dyno'd his 450hp ethanol fueled 406 V8 and it made 285WHP. TH400 trans.

Sweet! I'm looking at 15s. I wish someone local was selling theirs but no one ever is.
