Do you feel the LS2 is a disappointment?

[Blade]

It dynoed in at 343 rwhp and 335 ft/lb torque.

[Anomaly]

Why would I? It's an improvement over the LS1. Isn't that the goal?

[Narcosynthesis]

:weaksauce:

[WTFBEES]

I'll make that decision after we get more than 1 C6 dyno'd.

Yea, no kiddin huh? :lol:

Btw, the LS2 was just an improvment on the LS1...it wasnt made to be a barn burner. I'd say GM did a damn good job of that.

[Wolfgang]

You remember how it reacted to JUST LTs. 30 rwhp gain. That means that GM has restricted the shit out of this car. Wait until we see some bolt on LS2s.

[briantech]

LS1: ~295 rwhp
LS2: ~350 rwhp


Considering all they did was bump the "1" to a "2", i think its respectable.

I'm more dissapointed in the LS6. It should have like 600hp!

[esandes]

with small bolt ons it will go ~400 RWHP. that's not bad at all.

Wait until we see more than one ls2 on the dyno.

wait till we see a broken in ls2.

wait till we see a factory freak ls2 :) :)

I can't believe people complain about 350 RWHP while getting 24+ mpg, we are so nit picky these days. :yup:

like everyone else has said:

#1 - one car has been dynoed, well i'm sure more now.
#2 - they're not fully broken in. i bet they'd make a tad bit more power once they get some mileage.
#3 - longtubes = 30 rwhp gain, and even MORE torque! :eek:

i'm w/ briantech - the new LS6 or whatever will come in the new C6 Z06 better be like 500hp at least.

I'm not dissapointed in the least bit. Those dyno numbers are off of a car with almost no miles on it. I want to see a dyno of an ls2 with about 5k on it. Then start modding. Noone have even scratched the surface on the potential of this engine. I think it's a little too soon to be bad mouthing it.

Bullshit. Please show me a dyno sheet of a bone stock trans am throwing up 310 rear wheel.

maybe one or two factory freaks have hit it but the average stock LS1 camaro / trans am is not anywhere near 310rw. Figuring 14% tranny loss thats like 360 crank horsepower.

no way. you're saying stock LS1 formulas were underrated by GM by 55hp?

What rock have you been hiding under? Lots of 02s dyno'd in the 310 area. My friends 02 M6 WS6 dyno'd I beleive 308rwhp with just a flowmaster muffler, which everyone says is detrimentel to performance.

My A4 02 WS6 dyno'd 310rwhp with a flowmaster muffler and heavy ass 17x 11 rims in the back.


Yeah yeah I know you said stock but the mufflers arent known for adding horsepower and the big ass rims are known for robbing hp.

The 310 rwhp was pretty standard for 01 and 02 stock M6 LS1 f-bodies. The most recent dyno day I went to, I saw several stock ones dyno 315+ rwhp.

I don't think its ridiculous that anyone would call the LS2 a disppointment. They're just hitting the streets and we haven't seen that many dyno numbers of these things after they've broken in and with mods. Someone posted a dyno sheet from a pre-production 05 GTO and it did about 350 rwhp. Thats pretty damn good.

[LS1MONSTER]

I thought the LS6 was doing just fine with the stock factory rating at 405hp. The LS2 is rated pretty much the same.. ehhh go figure I guess.

The car only had 45 miles on it. :rolleyes: At least give the thing a chance to break in. That can make a substantial difference.

I think they'll be making around 350 rwhp or so w/ some break in miles on average. Thats about 40 rwhp more than the average 01+ LS1.

no way. you're saying stock LS1 formulas were underrated by GM by 55hp? They were under rated IN THE F BODY. The same motor listed as 350 HP in the 04 GTO is the same motor in the 01-02 F body basically. The 305 HP for Z28, the 325 for SS/WS6 and even the 345 for Firehawks were all underrated. Pretty simple stuff.

:rolleyes:I think they did a little more than just bump a "1 to a 2". How can you be dissapointed in the LS6? Its closer to the motor you have in your own car than the LS2 is. I'm w/ everyone else.... 295 rwhp may be what a stock 98 Ls1 like your own is putting down, but the newer ones, 01/02 are putting down a lot more. I know of one bone stock that put down 327 rwhp. yea, it was prolly a factory freak, but nevertheless.. 310 is not unattainable from a regular 01 or 02 stock LS1. Think about it... better intake and cam. It may be hard to grasp this idea, but a 98 LS1 wasnt the most powerful LS1 made...

BTW, arent you the guy that was blown away by a Z28 that you tried to run from a roll in 5th gear going 70?

Here is another dyno result from MTI in Houston.
335 rwhp

Remember folks, they're not going to give out all the new LS2 HP the first go round, there wouldn't be any left then for the next few years to improve on. I'm sure every year you'll see a bump up on the HP ratings.

As far as that pre production GTO LS2, I'll take that dyno pull with a grain of salt.;)

Actually it's NOT a better cam in 01-02. The addition of the LS6 intake made too much top end power so I heard so they threw that truck cam in to tame the top end down and bump up the bottom a bit. Didn't the 99 have the biggest cam?

[gsdz28]

I think it is way too early to determine that, those cars that were dynoed did not even have 1000 miles on them.....also when LG added headers the HP jumped by 40.

so once the engines are broken in, will can look at the dyno, and it's pretty obvious they are going to respond to mods well!

LS1 has 350hp, LS2 has 400 hp, so all I was saying was that an LS6 should have 600 hp. cause you know, 6 is bigger than 2, which is bigger than 1. it was a freakin joke, based soley on the number attatched to the "LS".

Moved to the LS2 Forum. :)

[DANSBIRD]

I think the motor has potential, but im sure there are some bugs to be worked out.... After looking at pictures and stuff, I am kinda thinking the 02-04 Z06 is the best one of all. The more im seeing the C6, the less im liking it. Dont get me wrong, it looks good, but the only reason i think id take one is for the simple fact it has a new, bigger engine.

This is just odd to me b/c normally, the newer version of anything looks better than the previous. There is only one exception iv found to this rule besides the vette and thats the silverados. I think the style before the current was the best looking of all.

I guess if you wanted to directly compare the C6 to a fourth gen f-body, then yeah it's not underrated like the f-bodies were with their 305hp rating, and easy 290hp rwhp results.

But the dyno results from the C6 so far (LG, Cartek) are totally in line and legit with a 400hp factory engine rating for the Gen IV LS2.

All this fuss is unneeded. Attention should be on modding it and tuning it for more, not whining about how it's 2hp under what a factory 400hp should be putting down.

What people forget is WHY F-bodies were underrated. GM didn't want to steal any of the flagship's thunder! Since the Corvette IS the flagship sportscar, there is no reason to underrate it.

Look at the C5- GM didn't underrate it, did they? LS1 based C5's made the same rwhp as the f-bodies (ie 340-350bhp), they didn't underrate the Z06 (most put down ~350rwhp), so why would they underrate the the C6?

This is an example of people hyping something up to the point that they are disappointed when it falls short of thier unrealistic expectations.

GM promised a 400HP Corvette for the BASE model, and guess what? They delivered. :cool:

When was the last time GM offered 400bHP SAE in the base model Corvette? I believe the answer is "never."

[Chief Pontiac]

What a dumb ass thread.

[Z28???HP]

This thread is pointless... The LS1 went under revisions year after year to only keep improving on the performance. GM will more than likely be doing the same with the LS2. Lets wait and see a few more dynos of LS2 powered cars/trucks and go from there. We know the stock manifolds are holding back power and more than likely they've detuned the engine a little bit as well.

So crack open a beer, sit back, and relax because more dyno numbers are coming!

Absolutely. How can a C6 that's substantially better than the base C5 it replaces in every way, not to mention cheaper, be considered a disappointment?

If there's a problem, its with people's unrealistic expectations.

EDIT: If we're talking about just the engine, this thread is still dumb. 343 to the wheels on a brand new engine and people are bitching. Give them a couple thousand miles to break in for God's sake!

[motorman]

as a owner of 3 previous C-5 corvettes and now a owner of a C-6 corvette i can say that the LS-2 has a lot more HP and torque than the LS-1 because you can feel it driving the corvette. the torque management systems on these cars to prevent damage to the drive line is what hurts the chassis dyno runs.last july i was at the corvette engine factory in canada to watch a engine dyno run of the LS-2 and it pulled 407 HP while i was there

Guys-

I had BPP in Florida put in an air box and LT headers on my C6 and the RWHP went from 348 to 385. Dont know how to load images yet, but if you want to see pix I can shoot you an e mail.

BTW- my car is not a Z51 - and I had the guys put in a cross drilled brake kit from a C5 and it fits perfectly.

Also, I hear that the cam the Ls2 has is a 2001 Z06 cam, Dave Bush from Cartek is working on getting in a hotter cam as you read this!!!!:D
