Bob Cosby's Cobra,Damon Phillips and Mike Smith all went mid 13s at 101-103 MPH stock with no mods(98s). Mike Smith actually hit 105MPH and 13.2-1ss against guys from LS1.com back in 1998. Cobras SHOULD be faster than GTs but most are not. They are undergeared and very tough to get the numbers with because they are hard to launch. Once moving they are easy to run fast with. You must shift them right at the redline and powershift(risky with the weak t45)-one miss and the EEC cuts you out in regards to timing. I can't drive a 96-98 Cobra(98s despite the same rating seem to run the fastest stock) to save my life stock. I can hit good traps(102-103 in good air) but my ets suck because I bog or blow the tires off. Mike Smith could hit 1.9s with stock tires and 327 gears-thats insane. He could ran at least 13.5s at Cecil,Atco and MIR. David T at the time had the fastest stock LS1(low 13s at 106MPH) but the showdown never happened. Mike's 98 dynoed 255 at the Woodbridge dyno.

The Gt produces more low end power so they can run with a Cobra of those years sans top end which is why they trap less. Dynos especially peak power means nothing. The Cobra is heavier as well I believe.

 

And i've seen a bone stock GT dyno 238 rwhp. So the Cobra did 28 rwhp more not 45 flywheel hp!

 

Somebody that actually knows what they are talking about unlike MauriSSio!

 

what did he just post was the fastest 96-98 Cobra?what was the trap speed? What was the E.T?now you said the fastest GT you know of hit 13.7 stock! Last i checked the times he posted were much better! so now you know the potential of the cobra in stock trim!

lol and once again,Steve Y gets

 

my friends 96 Cobra has hit around 107.2MPH w/ 4.10's, Cutouts and pullies. would would your car trap with the same mods? 101-102 most likely. Also, what did YOU dyno?

 

Ok I was wrong about the Cobra e.t. and trap speeds. But you were wrong about the rwhp and weight of the Cobra.

 

Your right, probably 101-102 mph. I have never dynoed my car. Countless others have dynoed cars like mine but bone stock to the tune of 225-238 rwhp.

 

whatever dude,lets just end this rediculous discussion and annoy the hell out of other people for a change

 

I saw a good running bone stock '96 Cobra put down 240 rwhp once (must have been a dog), then other's have put down 265 rwhp. The same car's rwhp sure varies a lot. I've seen LS1s vary from 282 to 321 rwhp, both stock. At least we both learned something, right? I agree on ending this!

 

I am going to say you both made good points, thanks for ending it though.

 

The fastest time i've heard that MMFF went with a stock '96-98 Cobra was 13.7. They must suck at driving those year Cobras compared to these guys.

 

Mine went 13.6 @ 104 at Atco back in early 1999. I know it did, because I was driving, and as much as I hate to admit it, I'm no better than Evan Smith, and likely worse than him on a true street tire. I also witnessed Mike Smith going 13.4 @ 105 in an identical 98 in the identical 100% bone stock condition. This was at E-town.

Just because it is or is not in MM&FF does not mean it did or did not happen.

 

So did Mike Smith do a 13.1 in a stock Cobra?

I know that. I am just surprised that MM&FF doesn't have the best time for a stock '96-98 Cobra, that's all. They usually have the best time for any stock car or at least come very close to tying it.

 

Yup. Cecil County raceway in late 1998. He backed it up on several runs that day. At the time, there was video of the run and a walk-around of the car, and several F-body folks vouched for it. However, I never quote that ET when discussing 96-98 Cobra's simply because it is so much better than any others that you will hear about. The hardest part about getting one of those cars to ET was the launch and a clean 1/2 shift. He had it down. Went through his first clutch inside of 18,000 miles. I only had my 98 at the track twice, and never figured it out. My 13.6 @ 104 was with a pathetic 2.18 60 ft....and horid spinning on the 1/2 shift.

 

Pretty loose term for stock tho. Seems like most guys with 320rwhp stock LS1s always have a 'lid' , or catback, or something small. They might be out there but you just can't believe whats stock and what isn't anymore. Heck, GMHTP took a 98 Formula and did a bunch of free mods to it and gained around 10rwhp. They probably still called it stock too
