    what ratio does a nostalgia funny car or nitro fuel altered run? I understand most alky fc run a 4.30 or 4.10, how high can a nitro car go?

    No gear rule in NFC. Most are running between 4.10 and 4.56.

    It depends on the rest of your set up like fuel system, clutch set up transmision gearing and timing. Some teams run a 4:30 or 4:56 to get the rpms up quicker to get up on the fuel pump. The 21 gpm NF/C pump is flowed at 4000 rpm(8000 engine rpm), any higher rpm is more fuel.

    so does that mean theoretically that a nostalgia funny car on nitro with a small 671 blower makes about the same horsepower as a alky funny car?

    By the ETs and mph I'd say there were pretty close.

    I agree with Slayer on the HP-comparision and as with the ratios.

    A slight diff in weight though: Top Alcohol FC 2400lbs and Nostalgia FC 2250lbs, if I remember this right..?
