I race a '03 Cobra the other day...he walked pretty good after 1st gear! It's bone stock! And he pulls from my friends '02 ZO6 from a 70 roll and the vette doesn't catch back up till well over 100! And the guy with the vette is a badass driver so there is no driver error! (he runs 12.0xx @ 115 in his BONE STOCK ZO6) That cobra is fast and that's all there is to it!

Thx. I think that's a common misconception. Although in this topic, I think the area under the curve goes to the LS1 not so much just because the Cobra is blown, but because the Cobra is a blown 4.6 DOCH. If you put that same blower on the 5.7 ohv Ls1 (with the same compression as the 4.6), it'll dominate the 4.6. My Vette in the comparison I made was blown, but had a power band very much like an n/a car (took a lot of tuning to get there)....whereas the Supras band looked like pike's peak

I try to explain this to people ALL OF THE TIME and its as if the just cant understand it . . The way the power is delivered and the duration of the power thrue the RPM's has alot to do with the trap speeds . A car with a blower has power spikes as to where a car that makse the same power with out one has a more steady apllication of power . More power thrue the entire RPM range instead of some power to a ton of power. So a car with less max HP can trap higher then a blower car for the simple fact that it can provide a steady line of High power and torque .Not just at high RPM's .

i dont see where it wins "under the curve" anywhere.

Of course the Cobra wins the "area under the curve" battle.....it's got 390 hp compared to a stock LS1. We're talking about equal hp cars. Compare it's dyno to a LS1 with 390 hp or a LS6 and you'll get the idea. What's funny is that my lil turbo 6 with 322 rwhp makes more rear wheel torqe than that Cobra!
....although it's band isn't as broad.

Find a dyno of a 390 hp ls1 and compare....or come up with another explanation why one car's consistantly faster than the other with equal hp. I said I haven't seen a dyno of the ls1, but based on it's superior quarter mile performance, area under the curve is a logical explanation....along with weight and gearing.

now, take a look at the cobra
mods:
pulley,tune,exhaust, cai. classic graph.
btw, i don't think your lil v6 put more torque than a terminator
the 03 cobra would win base on price/performance

. We all know the Cobra has More HP . Thatsa point that dont need to be made . Well , I take that back , there are still a few out there that refuse to aknowledge its great power and potential .
BTW , yellowvette , what kind of times is the 300 putting down . One of my best friends had a 300ZTT that dynoed 370 to the wheels and it would not and could not break a 13.2 ...Have no clue why ! It ran fine ." It was an auto though "

It seems to be it is the area under the curve.
MaruiSSio, we all know that the Cobra comes with more HP. We were trying to figure out why a LS1 with similar peak RWHP seems to trap/ET better. No matter if it is 450rwhp or 360rwhp.
I took MaruiSSio's numbers above and compared them to a 362rwhp Firehawk with the following mods:
-Ported Throttle Body
-Descreened MAF
-MSD Wires
-NGK Plugs
-QTP Stainless Headers
-QTP Merge Collectors
-QuickTime Electric Cutout
-QTP Off-road Y-pipe
-Speed Inc Dynotune
-------LS1---03 Cobra-------
RPM HP HP Dif
3000 190 195 -5
3400 235 225 +10
4000 275 268 +7
4400 315 293 +22
5000 350 326 +24
5400 360 348 +12
6000 355 364 -9
6200 350 366 -16
6300*** 362
Interesting numbers. As the stock LS1 cam dies off earlier the Cobra continues to make power. I'll try to find a similar rwhp dyno with a cam that extends the RPM range.
This is using the following dyno. The differences in the red and blue line are the tuning:
