Thanks!

He hasn't had it on the dyno, but generally they are in the 500rwhp range. I've seen a couple over 520rwhp, but I think it's more rare.

Thanks, man! Definitely some of the best races I've had to date, and the dude with the Cobra is cool as hell. Probably the smoothest time I've ever had setting up a friendly race.

Best mustang vs camaro runs ive seen on here in along time.

I was hoping you would edge him out , Gotta bump that 100 shot to a 125

Plus with equal passangers I think it would be door to door

This was a 40 mph roll, both cars in second gear, We're definitely going to run again sometime so I'll ask him if he want's to go from a dig. He's got drag radials so he'll probably be up for it.

curious what did you put down on motor i expected that to be diffrent, i ran 3-4 pullied cobras with my cam only 415rwhp and they were races like that very very close with me or them pulling a tiny bit. pullied cobra usualy makes 460 and a ported one around 510 i would think of good set of heads would just about offset the port and add 100 shot and peace. although you did have a passenger

Crazy I thought you would get him with heads and cam you should be at least 400rwhp and 100 shot should bump you up to close or more than 500rwhp and your car should still be lighter.. Good run but I thought it would be an easy win. Got to love those cobras!

Well put your radials on, then pop the hood and put those two spark plugs back in that pulled out for the first race! lol

Depends on the cam and heads because a good running head and cam ls1 will run with a ported blower cobra. I dont know how he did not win useing a 100 shot of nitrous he must have a mild setup I would think.

Your LS1 must not run to good. A H/C and nitrous LS1 should definitely roast a ported blower Cobra.

That what i was trying to say!!! lol But a bit nicer.. I ran a ported blower cobra and I got him from a 20 roll than when we went a 40 roll he got me ( a car and a 1/2) and he dynoed right at 500rwhp. I kept trying to run him at 20 because I notice his car didnt get up as fast as mine (Untill we went on a higher roll) Not saying every cobra is the same but what Im trying to get at is with a 100 shot for sure you should have won (with heads/ cam/nitrous)

Yup... with the OP's H/C and nitrous he should also have a **** load more torque AND more HP. Maybe its an LS6 cam and regular 243 heads

415rwhp cam-only isn't exactly the norm though... it really depends on his h/c setup.

I have Trickflow 215's and my cam is a 230/236, .581/.581.

My car went 11.63 @ 119.7 mph on motor the only time I took it to the track with this setup.

I'm not big on excuses so I didn't mention it, but for those whipping out their score cards, the first run my bottle pressure started at 950 and dropped to 800 and then second run it started at 850 and dropped to 700.

We are going to rematch as some point with equal passengers and me having a full bottle (like I said, the guy is real cool and is definitely up for it). We'll also do a run with me on motor to show the difference.

GatorFan08, I just got a set of MT radials on the car (295/45R17) so I have no problem with dig runs

As for cam only cars beating ported Cobras, either the Cobra driver can't drive for crap or the fbody was seriously light. I've run them when I was cam only and PSM ran them with his mild head/cam and there was no point at which the Cobras weren't pulling, except for the guy who couldn't drive, and he would still pull ahead of PSM in between shifts.
