Does anyone have or know where I can find a stock dyno for a cobra. Hopefully someone has one around 1996 but any dyno will do. I have heard that they dyno at 278-285 but its hard to believe cause I thought the drive-train loss percentage was higher then 9%. I would like to see a dyno graph but I am more specifically looking for the drivetrain loss percentage. Thanks!

the only ones i know of stock that dyno in the 270ish range are the 99/01's. the 96-98's dyno more around the 250 area. the average drivetrain loss in a manual car is about 15-18%.

96-98's usually hit 255-260.

99's before fix were hitting 240's and after around 260ish...still low.

01's were in the mid 270's.

I think my car was a freak. I hit 279 with a cat back and chip.

MotorTrend had a dyno comparison on mustangs and fbodies in Feb. '98. basically, the cobra put down 255.3rwhp and 267.2tq and driveline loss (coast down test) was about 35hp which put it around 290hp instead of the advertised 305.
