BHP is basically what HP the engine produces if it were say, tested in a lab. No accessories hooked up to it, no transmission, none of that. The RWHP is the HP that is seen at the wheels and what is put to the ground. It is lower than BHP due to the losses from the transmission, various pumps on the car, friction etc.
Get it? |

Yea so when they say my car makes 323 (I think) it really doesn't?

I'm assuming you have the V6? The engine would make 323 on a dyno, so technically, yes it does make that much. Does that much HP make it to the road? No.
For instance my 2SS A6....rated at 400 HP, I'm only seeing proably around 320ish to the ground. Automatic transmissions have a bigger loss than the manuals do. All this is easily displaced with a few bolt ons though! |

Also, I thought the quick math on loss to the wheels was 15% for the auto and 20% for the manual. |
