Im running a very nice setup turbo setup on low cr fully built typer. Now as far as actual drag racing goes, Ive got a 14" tall FMIC. My bumper is a stock eg front bumper right cut out grill, however its still the factory size grill. Should I cut the bumper up at all and open up the grill for the FMIC? Does it make a difference? Also running a topmount setup , So I was thinking about modding a ebay set of headlights and hollowing out the dr headlight to run a veolicty stack. Is that a noticable mod for the 1/4?

 

Keep it clean leave the bumper alone

 

enough air flow should hit the stock size bumper

 

Ok, I didn't know if it would make a difference enough to do it.
