from what i can see on it...(wich is very hard to see)
i think it says 142.36 max power...145.31 max torque..

...i thought i read somewhere it 04 ra had ~162hp stock..(i could be wrong tho......who knows)...im sure 05+ if they didnt stay the same, they went up...

They stayed the same throughout the years. That number they gave was at the crank. Still need to factor in drivetrain loss

The dyno graph is in my S&S thread if you want to take a look at it

My brother's car (spec-v) is similar in the respect that his advertised hp is supposed to be about 175 but when his forum stuck a stock unit on a dyno they found it has maaaybe 146hp (?)

You need to consider where the numbers are coming from (at the flywheel, wheels, crank) and what kind of dyno you're using

mustang dyno and the numbers were at the wheels that i was producing.

also got to factor in that the AT eats up more power than MT

that's pretty good for an auto with bolt ons and stock compression...
