347 mustang borla XR-1 mufflers
I am changing from XR-1's to the Pro XS mufflers and i wanted to see the
difference in sound. That is why im using a sound meter. I will post the
video when i put my new mufflers on.
81 F100 burn em down
81 F100, just a little 351W stroked to 427, AFR 185's, perf rpm cam, perf
rpm intake, WC T5, 3.50 gear in 9in, out for a little burnout action
F100 408c Cleveland drag race 1/8 mile
This pass was leaving off of the foot brake at about 3000 rpms. Converter
flashes to 5000, so it hits pretty hard. Ran a 1.903 60', 8.029 @ 89.85.
1.5 turns preload on both sides for Caltracs, 7/7 on Rancho 9000's, 14 psi
in the 325/50r15 M/T ET Streets. Seemed to kinda initially spin and then
hook and bounce.
