I just recieved this months copy of MM&ff magizne and they had a contest between the newest comaro SS and the new '03 cobra. The thing that surprised me most was the chassis dyno results.

The first pull was without changing anything, 381 RWHP and 374 lbs-ft, They then said how Ford had to put a very restricting air silencer on it so the new cobra would pass niose regulations. They then removed it and did another pull......

394 RWHP and 375 lbs-ft!!! If you take into account a 12% drivetreain loss thats 448 flywheel horse power! thats an extra 13 rwhp from a free mod, Just imagine what a new pulley for the S/C would do.

o by the way the SS made 317 RWHP.
