Nice run, H/C LS1's are definitely quick.

Unit..How much psi are you running to make 620 whp? I actually just picked up a KB 2.2 and have my 60# injectors, just need a BAP and cooling mods.

Sorry to get off topic

 

19psi (2.76 upper pulley/stock lower).

That's through stock cats with only 18.75* of timing. Zero cooling mods here.
Stock rails, stock pumps, 55lb injectors w/ a BAP.

 

Power over the curve huh? I'm guessing you mean power under the curve.
Ever see a graph of a positive displacement or a roots blower car? The area
under the curve is downright nasty, far better than a N/A LS1 generally
speaking. There are other reasons why LS1's hold their own nicely.[/QUOTE]
yeah weight is one of them against a cobra, at least for me, ima a no options car, lol

 

Yep, my bad, power under the curve.

I'd like to see a dyno graph, for comparisons sake, between an 03 Cobra that is stock and a 01/02 LS1. Anyone got one of each?

 

Nice, I have a 4# lower so im wondering what I should do. I am buying the KB off Red Shift, he said he has a 17 and 19 psi pulley. I may not get the cooling mods, a few people have told me I dont neccesarily need them. Im also going to be on stock cats, the Bassani OR X pipe was just too loud for me. Thanks for the info

 

Unfourtunately I dont have any Vid's or Digital Pic's of the car or even my car yet.(except for the engine and engine bay from one of my old post) https://ls1tech.com/forums/showthrea...16#post4610316 Me and my brother want to run both cars together, I wanna try to get a digital video camera for the run,
me on a 150shot and him NA. The power should be close but he's alot lighter than me . I think He'll be eat'in Oatmeal for Breakfast. Again Great Kill Krab!

 

Ask and ye shall receive...

LS1...


03 Cobra...

 

421 WHP on a stock 03 Cobra? I would say 360 to 380 WHP is more normal from what Ive seen at the local dyno. Almost 450 FWHP is not at all.

 

sounds about right....nice kill
