Mustang Dynos are the most accurate dyno when compared to factory ratings. A stock ls1 that's rated at 350 flywheel hp will make 280 rwhp. Most stock trucks that are rated 275-285 hp will make around 220-230 at the rear wheels. To figure your estimated flywheel hp take your rwhp 208 /.8 (20% drivetrain loss) equals 260 flywheel hp. So considering you only went to 5000 rpm and not to 5800 rpm when your stock cam flattens out, your numbers really are not far off.

 

Some call Mustang dyno's dream killers. Reality check is more like it.

 

let's hope that next time I'll be able to put out at least 300rwhp lol

 

Go to a dyno jet if you want inflated numbers.

 

Yours truly does not like the Mustang dyno. It's a real kick in the pride department.

 

 

..I hope to get at least 300rwhp on a MUSTANG DYNO
