i was watching a couple dynos today and i was wondering if anyone knows how much hp actually makes it to the wheels in an automatic.

 

The person before me put down 171 at the wheels with his AE (intake and y pipe). I didn't see any stock 2k's dyno.

 

People have dynoed them before, I think...

I can't remember who or where though so I can't verify that. (maybe Russ?)

However... this is the best comparison I can give you at the moment, and it's a big part of the reason why I believe a 165~170fwhp figure for 2k autos.

The stock 2000 Acura 3.2TL 5-spd automatic in the garage. 167.7fwhp... IIRC the CF was 0.96 or 0.98, I forget... but yeah. I expect Acuras to be putting out rated power at the crank (unlike Nissan, who seems to lose 3~5hp over the years as emissions crap kicks in)... so yeah.

Not a good comparison, but I think it's good enough.

 

My auto 2K maxima with only a K&N drop-in airfilter dynoed:

Max Power = 174 fwhp
Max Torque = 172 fwtorque

Hope that helps. Later
