NOS is really a drag racing application. I was at Automotive Specilaties yesterday while they we dynoing a drag car. 477 CI aftermarket motor in a Firebird, tubed out full drag slicks roll cage etc. 8.5 second car.
It made 485 rear wheel HP off the NOS and 850 when sprayed. They emptied a NOS bottle in 4 shots on the Dyno.(they had 8 bottles with them) and a big tank to refill them in their car hauler.
NOS is for drag cars!!!!!!!!!!!!!!!!!! do the head, cam, header, thing and you have power all the time.... The American mentality is drag,,, I am a road racer, Putnam park kind of guy and NOS has no use there... Floor It,,, especiall with size 15s
