    ZL1 Dyno numbers

    So my vendor goes and tells me he just got a new ZL1 for another shop car(outside of his 750whp whipple'd cts-v sedan)....he puts it on the dyno and here is the outcome. He is actually going to bring the car up to AUTOCouture when he tunes my car in june sometime, so i will def be checking it out. He said the car ran 11.43@120 stock....he said tires, tune, pulley, and intake and this car will do 10s with no problem

    500 to the wheels stock... that is pretty strong. Can't wait to see the new GT500 numbers though.

    Interesting, 500whp is a hell of a lot more than the regular SS model.

    Well you still have a fat chance when you have a built motor. You're going to be at 800 whp range. I got nothing on that.

    Doesn't this sound a bit optimistic? I realize it's putting 500 to the wheels, but an 11.43 pass for a car that weighs 4300 pounds with the driver is pretty impressive.

    Or has my morning caffeine not kicked in yet??

    Yeah, that's what I was having trouble with, the fact that the ZL1 has about a half second stock on the CTSV. I didn't think there'd be quite that much disparity considering the ZL1 is only 25 or so HP more than the CTSV, but the V is a bit heavier as well so that plays a part. Could be that the ZL1 is geared better for the quarter than the CTSV...I dunno'.

    Bottom line is you'll be having your hands full when these ZL1's and the '13 GT500's start seeing some mods...Click here to enlarge

    you have to remember, domestics are built to do straight line hard acceleration, ,atched with experienced drivers that have been doing it for 20+ years, unlike the european crowd that does not do this.

    lots of american cars put down low ET with un-impressive mph's

    Yes; agreed.

    I guess I was looking more at this ZL1's quarter mile time of 11.43, comparing that with what a stock CTSV can usually run which is what, 12.1 to 12.4ish (?). The 11.43 just seemed too fast for a car that has 25 more HP than a CTSV and is in the same general ballpark weight wise.

    The new M5 also makes nearly the same exact HP as the CTSV, (weighs a few tons also), but manages a 12 flat (or so) quarter mile run based on early reviews.

    Seems the CTSV, M5, and ZL1 should all be in the same neighborhood performance wise, with a slight edge going to the Chevy for more HP and a few less pounds. But damn...an 11.43?! Props to Chevy.

    EDIT: And yes, all this paper drag racing and comparing HP, vehicle weights, etc. is useless for any real world conclusions...but it makes the work day pass a bit faster.

    Dyno numbers seem a bit optimistic (DynoJet), but sounds about right considering it is a 6.2L with a 2.3L TVS blower on it at what, 12psi or so?

    Stock SS on our Dyno we've seen about 350ish IIRC.

    6.2L with a 1.9L TVS...only the ZR1 has the 2.3L

    torque curve looks very nice, car too heavy though...
    Some people live long, meaningful lives.

    Other people eat shit and die.

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

    Almost 30 whp is a pretty big variance but can be chalked up to correction and weather. We need a larger sample size.

    The European crowd is becoming straightline to a large degree. It all really started with the '03 E55.

    The problem is most I see of these cars hitting mid to upper 4xxrwhp range from what I see. But more are getting done and the results are being published.

    I think from what I have seen thus far the upper 4XX range is a more realistic representation.

    Honestly I would like to see that car with around 325 to 350rwhp. Turbo'd with a slighter lower compression would work. The LS may upset the balance with too much power & tq
