I call BS. He doesn't have one. Nor does his dad have an 02 SS. If he had ever drove an LS1 he would know they don't feel fast off the line. They feel fast in the upper RPMs and they really seem to pull hard at about 60-70 mph. I assure you an 03 cobra will feel faster than an LS1 off the line.Kilgore Trout said:What kind of car do you have?
I checked his previous posts and in one of them he says he has an 01' GT 5spd.Kilgore Trout said:What kind of car do you have?
03ghoststang said:here are some dyno graphs
here is the SS dyno
View attachment 495303
and here is the one for the Cobra
View attachment 495304
so there is a huge differnce in TQ curves
but non the less they do pull harder than our GT's
poorcollegekid said:yes...true...but also remember the IRS isnt as efficient as a straight axle. which really gives the fbod the advantage...but once theyre running...the LS1's ass SHOULD be grass to an 03 cobra. The LT1 will feel faster than an LS1 off the line...and by off the line i mean up to 30mph then the LS1 will have it. running through 1st gear in an LS1 is pretty wicked. but to the thread starter...gears...tires...suspension....thats what you need.
I think there are two sides to this. One is how FAST the car actually leaves the line and the other is HOW it deploys the power.HWYSTR74 said:what do i have to do to my car to get "quick starts" off line? ive driven an 04 SVT Cobra and that was pretty fast but I just dont get the same kick off the line as i do when I drive my dad's 02 Camaro SS (LS1, 360hp) any suggestions?? Price range within reason i mean dont tell me swap my motor. lol thanks guys

But even in an auto by 60mph you will have gone thru 1st gear, in a M6 probably 2 gears. The engine will perform the same in each gear. 4000rpm in 1st gear the engine will be producing the SAME torque and bhp as 4000rpm in 4rd.wanta5.0 said:They feel fast in the upper RPMs and they really seem to pull hard at about 60-70 mph.
undoutably, but 0-60mph times are probably pretty similar (manual gearbox). And how fast doesn't always accurately represent the sensation.wanta5.0 said:I assure you an 03 cobra will feel faster than an LS1 off the line.
Funnily enough this is a debate thats been on going on one of the LS1 forums.ponysarepretty said:The LT1 pulled hard from the line, the LS1 pulled hard in the upper range... but they all pull hard compared to the 2v...

The main difference is OHC to OHV. Push rod engines usually produce a lot of low down grunt. The 2v SOHC unit is much more of a rever and makes it's power higher in the rpms.
The Cobra has an advantage of a positive displacement blower which will make lots of power down low also. But many have trouble launching with the IRS so the sensation may well be different.

LT1 vs LS1
In fact the LS1 produces 90% of it's torque by a mear 1500rpm. And at 2500rpm it is producing ~340lb ft. The LT1 only has a PEAK of 325lb ft which is at 2500rpm.
People tend to think that because the LS1's PEAK torque is at 4400rpm it has no low end. When in fact it is considerably stronger down low than it's predecssor. and keeps pulling almost to the red line.
The only way to get the same torque from a 2v 4.6 is with a postive displacemtn blower. Although the new 3v unit does a very good job STOCK.
To offset the way the power is delivered you can alter other parts of the car, such as final drive ratio and sticky tyres. This will all imporve the sensation (and make it quicker too) but they won't however affect 'how' the power is delivered.
Yeah, I've noticed a few people on here saying that the LT1's will pull the LS1's off the line, I really didn't feel like getting into a big debate about it so I never bothered correcting them. Having owned [and currently own] and raced many LT1's and LS1's, I can say yes, you are correct.300bhp/ton said:I think there are two sides to this.
