Look at your e.t. vs. trap. This is exactly why an LS1 running your exact e.t. would start pulling hard in 3rd and trap much higher for the same 12.00 e.t. You might pull a 12 second LS1 off the line, but by 3rd/4th gear(end of 1/4) he would be starting to pull past you as indicated by a 118-120mph trap. You too would have problems with the 3rd gear "phenomenon."

WTF? I noticed that all the 3rd gear rapeage is on mustangs.....ever consider it might be when the stangs loose power. I dont know, but I can see some of you guys are underestimating the power of cobras.
Couple issues of carcraft ago, I saw an SN95 Cobra 4v running low 10's on motor. It was a 331ci 4v cobra motor, i was damn shocked and it wasnt even running boost. If I were you guys I would watch out for boosted cobras because I have seen some mean *** ones take some money from a couple locals at the street race hangout. Those 4v motors for being so small make insane power with boost.

Was the Cobra you saw running low 10's red, with a navigator 331ci? If so it was probably Al Papitto and it's one of the quickest n/a modulars on the planet. Not something you're going to encounter much, if at all.
Yes, most cars can be fast with with boost.....

I raced a 97 cobra from a 45-120mph roll, all i had at the time was an intake, and he was stock. by the time we hit 120 i had about a car and a half on him. we raced again with my current mods from 50-110 and i had about 3 cars on him this time. idk much about the big v8's but from ur sig, it looks like u have the mods that should easily give u the win.

About the whole gear + power adder issue on a '96-98 Cobra...my buddy has a '96 with SLP ORX/Loudmouth, an intake, 4.10 gears, and the smallest Kenne Bell (1.8?) running 6 psi...soon to be pullied. He dynoe'd about 355rwhp with a dyno tune and all the listed mods. I never got to straight up race him from a dig, but I cruised with him a few times and had a chance to kind of get into it. I have full intake/full exhaust/3800 stall/3.73's in my car, and maybe 100 lbs. of weight reduction. I don't put down as much as his car, that's for sure, but he hammered it, I did the same maybe a split second later, and I was slowly starting to pull on him. From 40 to like 80mph, I had gained maybe a fender on him. His car is fast, but FI doesn't do as much as I would hope for that year of 4V.

Surely if I had some skinnies out front and some minor suspension mods and was willing to drive the car harder it would have went 11.30's. I never dyno'd the car (none in my area) but the guy I sold it to said it put down 455/385 at the wheels. These cars do have a lot of potential as stated previously and blower kits as well as the cars themselves are relatively cheap. They are something to watch out for when modded.

A roots blower is probably the worst type of blower to put on a 96-98 cobra. The heads flow like crazy but lack velocity. If he had put a centri blower on it with 8psi and everything else stock 400rwhp is easily achievable. 130-150rwhp is about the norm when bolting on a centri blower for the 96-98's.
RedneckZ- I'm talking about dig racing not roll racing. Once the ls1 gets into 3rd it may start to make up ground but it's too late. I leave the rolls for the fat chicks.

Take a look at the trap speed guy, 122 in a 3600 pound car w/driver and your going to get ball park #'s around 450. As I stated, I did not dyno the car, the new owner did. I could really care less about dyno numbers anyway, track numbers is where it's at.
