I know ive seen vids of a cammed bolt on ls1 beating a 03 04 cobra with a little less than 500 hp. Am i crazy, because ive had a few people tell me there is NO WAY. If any of you guys have some vids of a race close to these #s id like to see them and here what you all think.

ive also heard of all bolt ons with 224 cam possibly pulling on cobras.. i would like to know also. i know it takes atleast a big cam or a h/c setup to run with one atleast.

Had a friend with a bolton/cammed ls1 TA, I was 420rwhp at the time and I would pull three cars from 50-110. I have no clue what his dyno# were.

If the driver know what they are doing, and the suspensions are close to equal (mainly referring to the IRS on the Cobra) It does not take that much more RWHP for the Cobra to keep up. An F-body is going to need either one BAD *** cam, a bad cobra driver, or more than just cam and bolt-ons to beat a 500 RWHP cobra.

(just my opinion)

i have a full bolt-on camm'd ls1 camaro, dyno'd 390 hp and i raced my friend's 03 cobra putting out 436 rwhp and i would win by a fender from 20-125, it was so close it could have been a driver's race but i also have 150-200 lbs weight reduction. I dont have a big cam but i'd expect a 420 rwhp ls1 to hang with a 470 hp cobra, probably not 500 tho

Oldbones

Remember the stock 03 weighs 3650lb without driver so it takes about 35 more hp for the cobra.

SSilver Bullet

^^ i agree thats the message i was trying to deliver

SSilver Bullet

btw nice cobra, must haul *** with 640 hp, tons of torque and weight reduction

Oldbones

It's fun Just a 100 shot Just got it together this winter so no times yet.

It would be an easy win for the LS1, im guessing it will put atleast 7 cars on the cobra. BTW nice car oldbones, I like the hood.

Well my car without me is 3350 with me is 3520. Lets say with driver the cobra is 3820 so 300 pounds more for the cobra. That would be a 35 hp difference??? I suppose that sounds right. That said i still need pulley some kind of ram air, cut out not to mention i still have ls1 heads and intake. Im looking at tsps prc heads not sure which ones yet. What heads do you guys think would do the best with my cam?? And where would that put me with the rest of my bolt ons plus the heads and an ls6 intake. If im at 390 hp now and 372 tq if i add all that stuff shouldnt i be in the 450 460(minimum) range all motor??? does that sound right?? only 2 more grand lol plus the juice. is a 150 shot safe for me( im thinkin tnts power ring system) ?? I think thats all the questions i have for now lol

Sounds like you must have a snake lined up already!

If you are making 390 than the 150 shot will give you more than enough power to take down a Cobra with less than 500 RWHP

dae04383

Yea there are a few around here i just wanted to see what kind of weight hp difference there is between me and them. There is one tt03 and a t03 around they are way over 500 i think 650 to 750 range. Im hoping with some heads finishing my boltons and a 150 shot i might be able to run with some of them, but i dont know. lol SO where my car stands now i could take a lightly modded 03 04 does that sound right.

dae04383

give me some idea on heads there are too many out there. Is there anyone that has the prc's from tsp????

Oldbones

Your doing it backwards, match the cam to the heads not the otherway around.

well that was a useless post.... speaking of

I would say the ls1 needs a little bit more hp to take on a 500hp cobra. a 420 hp just isnt gonna beat a 500hp unless there is a big weight difference

Publix

Trust me the LS1 will win, I know a lot more about cars than you ever will, you

dae04383

I dont want to get another cam yet so i need to match it this way.So what heads would work the best with my setup/cam. Those prc's supposivley have produced 50 hp gains alone. I want to talk to someone who has them installed with a similar cam as mine.

In a perfect world the cobra should win, but if you watch them at the track (and this is coming from a prior ford guy) the ls1's usually seem to have the favor. Maybe all I seem to get to watch is bad drivers, but I've talked to a couple guys around the 500hp range with their cobras that were only running high 11's- low 12's, and getting beat on by some bolt on fbodies. From a roll race its going to be a lot closer but no one seems to be able to cut good shortimes around here and thier et's are crap because of it. There was a VERY fast one at the track one night though that had a built AODE and was cutting some 1.5x 60's and doing very well.
