    500hp sc

    Hey guys, I was out at a local car meet..if you could call it a meet. just a few guys hangin out in front of a bbq restaurant. anyways, I was talking about my cougar and what's done to it and my issues. usual car talk bs. then he says that he's currently tuning a tbird supercoupe with a coy miller stage 3 motor in it with an mpx and all the supporting hardware. He says the guy he's tuning for spent 15k on the motor and makes 500hp. I was surprised to hear this news because I've been on here for a couple years and I've been youtubing and streetfiring videos of supercoupes and never heard of this guy.

    anyone on here ever heard of this guy? he's got a black sc with silver striping/trim, lives in south florida on the east coast. I'm more surprised that the guy knew the supercoupe terminology, such as magnum powers, coy miller, m5r2 transmission, cobra irs swap, yadda yadda. its not every day you meet a total stranger that is into these cars as much as you.

    IIRC the SC owners first name is mike.

    re

    There are many sweet high HP cars out there who don't post on this site.

    Heck theres a guy named George he has a pretty sweet ride called SWT SWF something like that I think ! He don't even post here anymore and he owns the freaking website.



    Watch out there always someone faster !

    500 with an MPx seems optimistic even if we're talking about crank hp. At the wheels? Let's just say I'm skeptical.

    I recall meeting the owner of that 90 Anniversary SC. I believe he said he lived in Jupiter, FL or somewhere in that general area. A group of us met him at the Silver Springs All Ford & Mustang show back in January of 2008. From what I remember, his name was Mark and he was fully aware of the SCCoA but didn't hang on the site at all. His SC was really nice and it was obvious there was a lot of money and time spent on it. He did say he had a Coy Miller engine and was working on or had installed an aftermarket ignition system.

    That is all I can remember. I don't recall taking any pictures of his car because it started to rain after we were at the show for just a few hours.

    yep I was in hobe sound just north of jupiter tonight where I met the guy. I dont doubt the 500hp claim, I think its possible with a built motor,mpx, and some sort of meth/alcy/n20 injection. the guy has a stock ecu/harness with a quarterhorse piggy back tuning hardware. Quarterhorse is actually what brought up the convo of his car in the 1st place. I'm gonna have to see if I can find this guy locally and get a few pics and maybe some friendly 1/4mi runs. word around town is that he'll be at bono's in stuart next tuesday for the meet.

    Remember that some of these folks that claim those numbers are basing them on engine dynos, not chassis dynos. Most of the cars over 400rwhp would likely be over 500crank horsepower.

    We're used to rwhp numbers as most run their cars on chassis dynos. But a lot of people, when they talk HP, are talking crank hp.

    Most guys that own old muscle cars talk theoretical crank hp. If hot rod magazine said this cam and heads equals 400 chp, then they have 400 chp. I've met very few people that have actually had their motor or car hooked to a dyno.

    Actually, if the engine in question is actually a Coy Miller engine, then it has been engine dyno'd.

    Most hot-rodders just get a crate engine or build something and their engine shop dynoes it. They put it in the car and forget about it. Those claim Crank HP.

    Knowing you rwhp and rwtq is just a side benifit, of getting your car Dyno tuned.
    The real key is, that your car is setup to effectively transfer that power to the ground.

    Chassis dynos are good for:
    1. Validating modifications you intended to make more power with. (or proving you were wrong)
    2. Giving you your cars power curve so that if you are manually shifting (either due to a manual transmission or a manual valve body) you can get a sense of where you should be shifting. As well as getting a good idea of when you change gears or tire sizes what impact that will have on your shift points.

    #2 can be done with an engine dyno initially, but isn't as reliable once you start modifying. #1 again can be done with an engine dyno, but you have to pull the engine each time.

    I just mentioned it because a few people here have 500hp SC's as well as lots of folks that don't ever come to this website.

    Not a chance. If it WAS him, it would have been 600hp on an top secret "experimental" M90 with no nitrous, factory weight, and runs 8's!
