    I think 8500 would be, in the best case scenario, pushing your luck. It could hold up drag/highway racing, but I think on a road course you'd have issues. The Procar m88 engines revved to 9000rpm but
    they were rebuilt after every race. If I built one of these engines, I'd probably keep it under 7.5k for peace of mind. Possibly blowing a ~$10,000 engine for a few extra rpms doesn't seem worth the risk to me. Then again, maybe the available aftermarket balancer works wonders and would soak up 8500 rpm easily.

    I do not know for sure, but I think the s14's stock valvetrain is what limits its rpm potential, which is why BMW kept the red line at 7000. Upgrade the valvetrain you're good to go; the s14's crank is much shorter being a 4 cyl so it doesn't experience the same issues with vibration.
    Ok i respect you. 8500 rpm is not 10k rpm though but the point is bmw was conservative.

    Who hit 720? Is there a dyno?
    It was in Germany http://www.nowack-motors.de/BMW-M-Mo...-58-708PS.html

    Correct Bmw had the s14 revs going well over 10k rpms in the e30 m3 racing hay day. I would love to own a e30 m3 turbo with a gtx3076 reving to say 8500rpms. See if it can give those evo's a run for the money. Maybe even a hta3586 with e85. Hrrmmi or or or the OP goes turbo, and keeps it a 3.6 with a gt4088-gt4094 with proper internals reving to 7800rpms. A raping powerband, and a sound that God himself would love. 4inch exhaust with a 4 inch cutout. Instant tq

    My friends Joakim from Jakan Racing, i belive 8.21sec was the best time he did and 270km/h, 1100kgs on the line race ready.
    He revved close to 9k with his 2,3L S14 , 900-1000Hp´..pretty nice

    That car is from hell.
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.
