A guy on this board that goes by Greenbean or something like that has a full weight camaro with 424rwhp and is trapping 119mph. Where are these lightened fbodys?

Yes, but us GM guys don't have forged internals from the factory w/ warranty...

Real easy to swap that pulley and make 450+ at the wheels without breaking a sweat.

 

$1500 isn't sh*t in the scheme of things...

Hell, a good exhaust system from headers back on an ls-1 can run over $2000 and we sure as hell won't put mid 400's hp at the wheels.

 

Hate to tell you, but leadsled posted a ton of 03 Cobra sigs and most of the guys making mid to high 400's (450-480rwhp) were only tapping 115-118mph, some of the 480 guys got close to 120mph, but they are too damn heavy. Thats why dyno numbers dont mean squat for the cobras. I would say dyno queens, but I have more respect for them then supras

If you havent seen them run at the track, then atleast go to stangnet or something and check people's sigs.

I met a guy that made 485rwhp in his 03 Cobra and he trapped 119mph. I also know a guy that has 430rwhp in his Firehawk (full weight 3700+lbs with driver) and he traps 120mph. Those are REAL WORLD examples.

 

I think there is a rule here, that you need atleast 1 post before you can pull the bs flag.

$3000???? I haven't seen a gold plated exhaust yet. I have what is considered the most expensive exhaust, at $850, and I could have someone custom fabricate stainless steel headers and I still wouldn't get to $3000.

 

Wow that was so insightful now how about you go shutup and sit down.

It just depends on the driver. I also post quite often but only in the lounge and that don't seem to add posts to the counter FYI

 

Hmm...OK, thats 1 out of the whole list! Weight reduction?? Most likely. Look at the rest of the cobras on the list.

 

If a 420 rwhp LT1 that weighs 3450 lbs. can trap 120, then why can't a 500 rwhp Cobra that weighs 3670 lbs. trap 124? That's only a 220 lb. weight disadvantage and an 80 rwhp advantage.

 

That is the question of the day.

 

Well it may be only one, but that proves it can be done. Like I said before it depends a lot on the driver.

 

I'm sure you could find your answer by looking at the dyno charts. Peak hp numbers mean little. Maybe the Cobra makes 500 rwhp for only a window of 1k rpms, but what about before and after that window? The Ls1 car might make peak power for 2k rpms or more (I've never seen a dyno on one). Look at the torque band too. Where does it peak? How flat is it?

Here's a good example. My first supra made 435 rwhp off bottle (pump gas), my supercharged vette made 443 rwhp on pump gas. The Supra made peak power at 5k rpms and only held it from 5k to 6k. Torque peak was up there too (can't remember the #'s). My vette on the other hand made peak torque much lower (with an unbelievably flat band) and held it's peak hp for a broader range of rpm. The vette trapped at 122 wheras the Supra trapped at 117. Almost equal peak power, equal weight, different traps. It's all about the area under the curve.

I seriously doubt that with 4.6 liters and an intercooled roots type blower pushing a lot of boost.

 

yeah, thing makes full boost pretty much off idle. if anything i think its FAIRLY safe to assume it would have a better tq curve than the ls1 if anything though i could be wrong.
