T-maxx, Man Just Take It What Its Worth What Do I Get Out Of Posting My Trap Of 113? In Reality I Don't Get A Damn Thing And Nobody Knows Who I Am Either. So I Would Be Lying For What? I Don't Know What To Say, Ok I Did't Trap 113, But In Reality I Really Did! Ps I Also Have A Professionally Ported Tb Open To 80 Mm, Ahpp3, And Asp Pulleys. Not Just A Lid And Catback! Sorry I Guess U Think Im Trying To Get Famous. Sorry No Hard Fellings. Oh And Yes I Have Some Suspension Mods If That Matters Too!

I know that I am new to this fourm but I believe OSCSleeper because I have a 01 SS and my best time at the track with only a LID and the FRA and gutted cats was 13.009 at 112mph and that was on the Eagle F1's. My best time on a set of Nitto's was 12.945 at 110mph. Next I have raced a 03 cobra at the track and on the streets. I have a friend with a 03 and the only mod he had then was a cat back system( I think a Bassinni) I hope I spelled that right. The first race at the track I beat him by a 1/2 a car. My friend said that he was still getting use to the car. The second race was a blow out because I didn't turn off the traction control. The 3rd race was a classic. I cut a .507 light and the cobra cut a .513. By second gear that cobra cam right by me with no problems. Third gear the cobra was a good 1-1/2 cars in front of me and at the top of 3rd it begain to even out . I must say that the car is pretty quick and if the person in it nows how to drive it it's going to be tough to beat it stock. Now this summer I will race him again. He now has the pulley,chip, full exhuast from the headers back(no cats) CAI, and he is having his S/C polished in the inside or something like that. I will have heads AS 5.3 stage2, cam 230/230, pulley, ported throttle body, 4:10 gears,kooks Lt & ORY(no cats)dyno tune and NX100 shot. Do you think I can take him or what? I think I should kick his *** but that's just my opinion.

You all can disagree with me, but I'm trying to make some conservative estimates that back his kill.

A) Say Your mods are probably giving you .3 (.1 for pulley, .2 for lid, exhaust and TB). M6's have been known to run 12.9 stock, so maybe your car is capable of 12.8. Your trap speed suggests this. Plus you had trouble launching at the track, as evidenced by your 60', 1/4 mile and trap speed, so we can't trust those 1/4 times, and your trap speed is So let's say that given traction you could run a 12.8.
C) Cobras have more hp, but they weigh 250lbs more and who knows how good of a driver this guy was and they seem to be inconsistent.
D) If they can run anywhere from 12.6-13's stock, as stated by some of the other posters, and you can probably run a 12.8 easily with traction and your mods, and you went from 10mph, thereby eliminating some of your traction problems, I don't see why you COULDN'T win.

Does it make sense that a 330hp car can beat a 390hp? Maybe, if you stop dyno racing and consider all the factors involved.

What happened to B?

T-maxx

A) On the best day, with the best driver, and with great track prep an Ls1 M6 on Eagle F1's with a lid, and even some tuning might run in the high 12's..Maybe. I have never seen this only rumors.

B)= missing

C) A street race does depend on the other driver. I agree.

D) You say 12.8 easily with those mods, NO. To run a 13 and under It will take at least DR's and or headers. Weight reduction goes a long ways also.

E) Where did he run? Post a time slip please.

The 2003 Cobra puts roughly 355 to 365 to the wheels but is about 300 pounds heavier. If you go by power to weight and factor in the gained hp on the LS-1, a 325 to 330 hp car can beat a 355 hp car. I've raced 2 2003 Cobras. The first guy couldn't shift worth crap so we looked like a freaking slinky (because I was completely stock). The second 1 I pulled in every gear and I'm only running about 360 hp. The sealed ram air helped I'm guessing after about 65 but the major difference was weight. We both had traction issues. At about 115 I had about 2 or so car lengths.

Those are low numbers for a stock '03 Cobra...370-385rwhp is quite common.

unit213

DAl1as- You're making 358rwhp/373rwtq with exhaust mods only...no cam?

Dal1as

Yep. Unfortunately I didn't get a before dyno. The people who worked on my car stated I was one of the stronger cars they've dynoed. In fact Heffners dyno is notoriously low.

As for the hp of the Cobra's. 2 of the car clubs I frequent here in the MD, DC area have a ton of 2003+ Cobras and the average hp stock on the dyno has been around 360.

unit213

Damn good numbers!

My friends and I must've gotten lucky then. We were all in the 380's on a dynojet. There is an issue with clogged cats too. You might here of an '03 Cobra laying down 330rwhp...that's why. Just fyi...

2 of them I remember were brand new. Weird. They were on a dynojet though. I'll check again. Maybe I'm wrong.

Here is one instance Until Just so you know I'm not making crap up.

One of the board members here (Seahawk) who's a local ran a 12.75 @ 109mph with nothing but an SLP option equipped (SLP lid, suspension and dual/dual exhaust) '01 Firehawk that had MAF ends as his only mod... this was on Firehawk SZ50s, no DRs and no weight reduction. So it is possible...

>>what do you mean they where on a dynojet though?? is there some other kind of dyno and if so what is the difference?

[QUOTE=ESMsilver00SS] Mach 1's have the '99 - '01 Cobra DOHC motor with 305 HP. QUOTE]

Actually ... the only thing similar about the 99-01 cobra motor and the Mach Motor is that they are both 4.6 DOHC.... they are a totally different motor ... different design block totally different heads diff. cams ... nothing is the same

well all i know is an 03 cobra with a 100 shot is fast lol. bunch of us went out racing, it was a vert, he said it was stock so we were all expecting to show him up, well only one of us beat him but his car would rape everyone else too, i was sad, need more power! my friends step dad has a cobra and SOTP feel yeah its fast but i dont think it would take me at all. then again its stock and there is a lot of potential out of these, cold air kits good for like 25-30 rwhp i have seen thats good, but boost also goest up 1 lb so you have to be careful lol

99-LS1-SS

I ran a 12.574 @ 108.34 on stock F-1's with no weight reduction and I had hooker shorties (which suck)with cats and only a few bolt ons.

2000WS6Vert

I've raced a Mach1 on the street....the guy couldn't drive very well...so we went from every speed imaginable to try and take driver skill out of the equation. I took him from every speed.....I would start to inch away as we hit 70 mph...and I had nothing but a lid on my 3.23 A4 vert.

As for newer Cobras......at the track I've seen them run 13.0-12.8 @ 110-113......heck....most stock M6 LS1's are very capable of those times....let alone slightly modded ones....and a stock A4 with a torque converter can run those times all night long.

Yes, there is the Mustang dyno which dynos lower.
