I see you got that by doing about 23% drive train loss. Is this really the standard for the WRX? I just find it hard to say my car has 429HP 468TQ haha.

Why would the dyno matter? I mean clearly one could read 200hp while another would read 230hp, but as power increases you'll still have the % or 30hp difference between. Do dynos have a function on them to show BPH or do you need an actual BPH rolling road dyno?

I am curious. I have the same car as yours ('10) based on your picture. I am Cobb Stage 2, Cobb cat dp and SPT cat back. Don't think I am anywhere near your numbers (330HP/360TQ) especialy if those are at the wheels? I plan on an AEM intake, BCS and refined tune next. I would like 300HP to the wheels and I'd be happy. Just curious, thanks.

I make just shy of 500 chp. Abiet chp/bhp numbers are totally meaningless.

Well I will take all the advice I can get. Thanks for the insight guys. Now, it's just a matter of time and money like everything else.

VS. the stock number from the factory/Cobb map numbers, etc. That's all I'm talking about. Granted if you took a baseline from the same dyno and then modded afterward the number wouldn't matter.
