Ram Air Induction
i then switched over to my custom dual 4" set up and ADDED 150 lbs to the car (6 point bolt in mild steel roll bar, reinstalled all my A/C stuff and left the A/C belt on) went back to the track and in sinilar weather i ran 11.7 @ 118. a tenth quicker and a mph faster than with the FTRA all will being 150 lbs heavier and having the a/c belt drag on the motor.
I'de say "Ram Air" works.
