I dont have an rx-7 myself and couldnt really find the info i needed. He says he runs low 12's with just intake, exhaust, downpipe and some tuning at stock psi. Is that possible and around how much hp would you be making with those mods.

 

It's not possible to run low 12s at stock boost with just those mods, not even with slicks....

EDIT: It may technically be possible but I've never seen or heard of anyone doing so. Most of the good drag racer times I've seen took full exhaust and intake at 12+ psi and drag radials to get to low 12s.

 

i wouldnt dout the person if he said he was running higher psi but he says he is running stock psi. also said he has about 315 hp but i didnt ask if that was a dyno or his assumtion. ill just have to wait till we go to the track.

 

I smell it. Does anyone else? Simple mods like that are not enough to make even the great FD that fast. Not a bad start, but still a while to go.

 

No way at stock PSI. No way at all without lots more than what your friend is telling you he has.
