HERE ARE THE DYNO NUMBERS
Impressed yes, scared no.
I've got to say his combo is very fuel sensitive. 100 horse from start to finish on jetting and slight timing change. I did pull 529.8 rear wheel horse and 568.01 rear torque so we are probably closer than we ever have been.
Isn't compettition great!
I wish we would have closed the exhaust to see what increase the open headers gave Brett. We really could have used another hour on his car.
My mustang was pretty well set up from the time we got there. I only gained 9 hp from start to finish.
