    Horsepower Question

    I have heard that the LS1 can safely run around 500 to 550 rear wheel horses until the block starts running into problems (unless it is forged)

    I was curious what the C6 coupes can safely run before the engine might start having problems?

    I actually read recently that an almuminum ls1 can put up with around 1000rwhp. Providing a proper tune, of course.

    hmm.....thats a first for me. I would of swore it was around 500 or 550. I could be wrong though, I've been so out of the LS1 loop the last year or so!

    I'd say 600 safely is the limit. You still have to keep an eye on fuel/spark.
    I've been running 561 to the wheels on my 99 since February of 04 and its still running strong.

    So would you say 600 to the wheels with an LS1 or an LS2? I'm trying to figure out whats safe with an LS2

    Blownc5, how much of ur drivetrain is still stock? im trying to get a ball park idea of how much power my 2000's m6 drivetrain can handle before theres any mods (besides clutch prolly)

    otherwise, aftermarket rear? built tranny? driveshaft? subframe connectors

    red, silver
    97 and 01 vettes

    Of course the important thing in those hp ranges are the obvious valves, springs, hardened shafts, built rear end, etc. JMO of course.

    Uh a "forged" block? Are you talking about block strength? I've never heard of a block splitting on an LSx, unlike the 5.0 community where 500HP is pushing your luck. Heck, I ran 576rwhp/590rwtq for 3 years on a factory bottom-end before pushing a head-gasket (my fault) and the engine looked perfect when torn down. The LSx crank is extremely durable and there are guys that have put down over 800rwhp by using forged pistons and ARP fasteners.

    cant tell u for sure stock c5 clutch, but stock zo6 (c5) clutch is good to about 450 flywheel horsepower. I got about 390 flywheel hp in my vette. so far no problems but im also running street tires.

    450 flywheel hp = at crank/engine, c5z06 have 400 flywhell hp, so 50hp over stock doesn't seem like a big deal. you sure it ain't 450 rearwheel hp?

    Can't believe I missed this, but I'm running a Spec stage 3 clutch/aluminum flywheel. Hardened output shaft too. I haven't run any sticky drag tires either. If over 450hp, the clutch will start going rather quickly!

    450hp not rwhp... wow...good to know man! thinking of getting me a C5 or C5Z06 in 4-6 months.
    probably sell TA, get a more daily ride, I drive TA only 2-3 times a month...
    too little to enjoy really, it's a semi track car... not really daily no more... so c5 full exhaust, tune for now will be a nice daily and wanna switch to M6 since they respond to mods gain 3-4% better.
