260 stock is rated at the flywheel, I put down 250 at the rear wheels. I'm making 310 at the flywheel.

oh...thats gay i thougth it was 260 at the wheels...how much is stock at the wheels?

lol, with an auto Ive seen about 215~220 at the rear. 5 spds are like 225 I think rwhp.

Stock automatics make 210-220 rwhp from the factory just like Matt said.
