    Great comparison. Might as well compare a Pinto and an Aztec.....

    I come from the n54 world, had the world record for while.

    They make great dyno hp, they do not run right for long
    It wasnt a jab, just an observation

    Why? Everyone wants to compare a gt500 to a c8? Whats the difference? M5 is closer to gt500 than c8 and gt500

    @LostM what are the honest weak points of the n54’s?

    I’m aware that 2jz’s and rb26’s don’t live up to their hype as well from head gaskets and studs to valvetrain etc.

    Well, a lot of enthusiasts may cross shop between a GT500 and a Corvette. I'm not stating that the M5 isn't a great car, but I do doubt that most here would flip a coin between these two.

    My point also.
    M5 is a great car and on paper matches up to the 500 in some ways, but in reality very few cross shopping.

    Starts with misfires. And no one can really keep them from coming back, plugs coils injectors need to be kept.on hand. Try as they might, inevitably, it will start missing
    Fueling was solved after i left, but that was a big thing.

    The autos suck, i was the 1st to attempt to rebuild that at 520hp, that failed

    If you keep them under 600, you can get a few good days in, but after that, its a daily struggle. This is why, regardless of the higher hp dynos through its evolution, the stats, 1/4, 1/2 60-130 never followed suit

    And exactly why I’ll keep to a proven American muscle platform. You can have a daily worthy, boosted Coyote/Modular at 1000rwhp and the rest of the drivetrain as standard proven Mustang fare.
    The DCT is the only wildcard in the new GT500.
    Its all if it can hold 1000hp as many suspect.
    I have personally talked to Tremec engineers standing at their display truck looking at a cutaway Magnum 6spd next to the 500’s DCT and it is beefy. They were confident in their new product.
    Great to have options with so many serious performance platforms.

    Given that Hennessey just came out with a 1200 ho package.

    It looks like it should.


    Sent from my POFS iPhone in a rage cause this is the third try.

    My real concern would be the DCT tuning.
    Mechanotronics (sp?) will hopefully be able to sense more power/load and keep hardcparts happy.
    It’s not like DCT is new, but hopefully the Tremec unit proves to be power mod friendly. The conventional 6R80 and now 10R80 has proven to hold big power 100% stock and that is also tuning dependent.
    As you know, these won’t be cheap!

    At over 80k and probably over 100k for the carbon fiber, the 500 will be crossed shopped against cars that were never before considered including and not limited to the M5. The honest part for me is the 80-100 is too rich for my blood. I need an oxygen mask going that high.

    Yes, after so many issue with that, I went to the E92 M3 ( 4.0 V8 DCT ) and supercharged that. That car was A-****ING-MAZING
    The problem is, as you of all can understand, 560rwhp is not a lot in todays world, when all my friends make 800+ on pump and 1k-1500 on race ect.

    So that got me looking HEAVILY at the gt350, with a TT kit.. but everyone i know said to wait for the 500. Im glad I did. Its the American version of the E92 to me. I had debated just going back to the S/C E92, but then jan 14th happened, and here I am

    PBD and Lund have both expressed they have no insight on the TCU yet. I dont think there would need to be a lot to get started other than increasing line pressure. Given the lack of TCU knowledge 21 days out from my build date, ive come to accept I may not have 800hp out the gate, and settle for just doing ported blower, exhaust and 93/e85 tune, and hope the E85 tune doesnt put me beyond the dcts stock limitations/put me into clutch slipping

    Most here cant even afford a 72k gt500. Lol at cross shopping a new m5, starting at 110k.

    If you don't the cash for said purchase you're not shopping anything, you're looking.
    Cross Shopping by definition would dictate that one could afford 72k for a toy car. Therefore your comment about most not affording is null and void. Near 80k out of the door for a base gt500, 100k is not to far out of the realm of possibility for "most".

    Now that time has set for suspense....

    I’d like to point out that the m5 went 130mph in the 1/4 being awd with just 617awhp and 4200lbs.

    The gt500 will have 700whp and weigh a sliver less.

    135mph will be very uncommon but I personally think it’ll happen on full moons in cold night low altitude environments after a nice hot day to heat up the asphalt/cement

    I know modern traction control engineers earn their paychecks, but you have a lot of faith in this car hooking up.

    impossible.. so ive been reading here

    just read below. trap speed and awd are somehow directly correlated to eachother
