Video from Saturday night (LEAVINU Vs. GT500 & KB Mach 1 vs. Collins and an R6, etc.)

its a 250rwhp difference aerodynamics had nothing to do with it. The gt500 would have to be 1500-2000lbs heavier than the c6 for weight to be an excuse. But a 75 shot would make perfect sense it would put Marshall at about 515rwhp and 540rwtq. Sorry Marshall but their is no way just like you hanging with a 570rwhp kb z06 not gonna happen NA.

Ford lists the GT500's curb weight at 3,920 lbs in coupe form and 4,040 pounds for the convertible and chevrolet C6 at 3132 lbs... Math doesn't lie

GT500 3,920lbs / 670whp = 5.8 lbs per hp. + with pass(150lbs) = 6 lbs per hp.
C6 3132lbs / 432whp = 7.2 lbs per hp.
C6 Zo6 3132 / 501whp = 6.2 lbs per hp. + with pass(150lbs) = 6.5 lbs per

In reality the GT500 should pull in both races... I mean the numbers are clear. But what doesn't make sence is that Lankhoss car is faster that Marshall's .... So why the GT500 even with a better wheel set-up got beat by a slower car?

Side Note:

GT500 owner should weight his car and do some GPS data logging to figure out why he is so slow.

Good killzzzzz

either marshall is spraying or he built a big cube motor. i just dont think it is fair to the gt500 to let everyone know his mods and let marshall act like nothing has changed on his car.

so here is a good scenario matt(slowhawk) and lankhoss ran about a month ago with matt spraying a 100 shot making 560rwhp and 620rwtq he barely pulled lankhoss. marshall claims 432 rwhp and ran better against the gt500 than lankhoss. so marshall would have been even with slowhawk with slowhawk spraying both light corvettes

power in signature.
If you feel those are not accurate and the car still makes more power then not sure what to say. Thats the power it makes and if you want to spot $50 bucks to see it on a dyno that works for me.

Not a lot of ppl here will offer to do that. For that I take my hat to you sir.

Let me cross post some info here, Coming from another thread:

Also, the driver / passenger in the GT500 are ~215+ each - the driver / passenger in the Z are ~165 and 145 -

Seems a lot of people are calling BS on this video on other forums (Streetfire idiots especially) and claiming that the dyno #'s for the cars must not be correct.

that guy in the white gt500 actually was on the dyno this weekend..and it made exactly 640whp

With this new numbers to back up the math... Lankhoss race make's sense withthe GT500 on 20s

GT500 has a W/P ratio of: 6.7 pounds per hp

&

Lankhoss Zo6 has a w/p ration of: 6.8 pounds per hp


So, Marshall your car had to be lighter that a stock C6 or their is something missing in the equation

The 640 RWHP GT500 is not in this video - that is the white one. He ran the black one with ~670 RWHP. They both had 20" wheels when he ran them.

LOL marshall... you broke under pressure! haha... oh well, i guess its good you came clean.

[RJ's325ITS]

i just dont think it is fair to the gt500 to let everyone know his mods and let marshall act like nothing has changed on his car.

Good point there....

The more I think about the GT500 the more it doesn't make any sence. Assuming his car is runing OK, his torque has to be retarted low like 500wtq, or is a show car with 500lbs in amps and TVs.. Otherwise his whp number are soooo wrong.

[LEAVINU]

his torque has to be retarted low like 500wtq

he said that night his rwtq was over 600.....I think @615/620 if I recall correctly.

No nitrous
stock 364ci shortblock


I didnt ask about ANY of his mods nor did he ask about mine; I wouldnt say its not fair for me not sharing.
