You don't know anything about twin screw's do you?

It's the second pic that wins out, nice broad, FLAT TQ curve.

Topend has more to do with torque bud not hp. Its common knowledge that roots have that weakness. Look at the torque dropping off after 4k. You proved my point thanks. Now does anyone have a turbo dyno sheet.

My 03 Cobra ran 7.22 @ 98 mph with 130 hp LESS than your friend has so If he can drive you might be in trouble.
A KB cobra with 550 to the tire should run mid tens all day and the stories about the rearends breaking are a little blown up.
I have watched a ton of cobras run in the tens with stock rears. If you let them wheel hop they will break right away.

Good luck and go get him.

I'm baffled by the lack of knowledge in this thread. Incredible.

My vote goes to the blown LS1. However, a KB Cobra is a bad ****. Trust me.

Ditto

KB cobra's are no joke, with a good tune and fuel system.

You, sir, know your KB Cobras. A fuel system is needed past 600rwhp. It must be upgrades past 500rwhp.

...and it's ALL in the tune!

Yes indeedy it is getting deep in here. As far as tq falling off after 4000 rpm, dude are you ******* dumb? The car is dynoing 490+ rwtq from 3000-5500 rpms. That is a great tq curve. You need to stop playing on the internet and go race.

I give the nod to the ws6 but it is still going to be a very close race.

those graphs are pretty confusing.... why dont they cross at 5252?

I think it will be close. With both cars making equal HP, I would think that the KB Cobra would have the better low end, which would give it a slight advantage off the line(with traction). You are a 6 speed, so you can get right into the powerband or the ATI, which helps, plus the lower weight. It would be a drivers race like everybody else said. Just make sure you get a video!

They do....At 5250 they are both at 500

If the KB hooks up I'd give him the win.

I went 10s with that power in my SS. My buddies 03 had 550+ 11.3s.

My vote goes to the LS1, but anything could happen.

Then your buddy is a shitty driver. I went 11.29 with 460rwhp.

I know some gentlemen that have gone 10.8-10.9x on nitto drag radials in KB Cobras. And the sad news is that they are full weight. I'm not saying exactly what their hp/tq numbers were, I think they were a little higher. They did trap 133 in the 1/4. Good luck, make sure to cut a good 60'.

??? Every single setup out there loses torque as rpms go up past peak tq. You havent got a clue. Roots and screw are 2 totally different chargers.

I attached a turbo dyno sheet from TTi's website. Do you see the torque fall off as well. There goes your theory.

Try to get a video of the race, regardless of the outcome I think it would be a good match.

LSONE, the top graph is HP, the 2nd graph is tq.
