From a roll the LS3 is tough, I know mine pulls hard from a rolling punch.

Read up some more on the 5.0, they arent maxed out from the factory. Mod for mod, these engines are pulling very close numbers to eachother. The 5.0 gains more on the tune as mentioned by UltraZLs1.

As far as mods listed, what are they counting as "exhaust"? longtubes, x pipes, axle backs? or x pipes, axle backs? or just axle backs? Now if they said "full exhaust" then IMO, it means longtubes, x pipe, axle backs are installed. What about the tunes, handheld tunes?? or HpTuned by a shop or even dyno tuned? Alot of variables in here, but that SS did pull away.

Nice video, wish there was a better breakdown on each car's mods

I know this is an old thread but I thought I could shed a little light on the discussion. Rather then go into a long debate as to why I will just say I sold my Z28 and bought a 2012 5.0 mustang. Now just an over view of mods and results:

Steeda CAI
Boss 302 R intake manifold
SCT tuning
Factory 3.73 gearing

Results. 424 rwhp
Track. 11.6 @ 119.3 on a tire
12.1 @ 119.8 on the stock 19's pirrelli's(race compound or something)

Now for the story for you to decide....

Ran a guy with 2010 SS last night three times. His car has Longtubes, Magnaflo cat back, CAI, Fast intake and Dyno tune. He said 452 rwhp. Six speed car

On the roll: Dead even pull to 122 mph ( end of 4th for me) 2 times the same. We each moved around a few feet on the shift but it was pretty much dead even.

From a Dig: I won by about three cars. The SS/LS3 was making allot of torque and would not hook up like my (honestly) wimpy (torque wise) 5.0 I would walk him through two gears and then ride the lead out to the end.

I know the guy in the SS for a long time. He can drive. Its just that the SS works like a GT500 mustang. Too much bottom end grunt for the tire to hook as hard as the little 5.0. JMHO and a little real world info.

Nice info.... strained my brain a bit.... Vince M. right? How are you, still have the LT1 car?

What are you shifting the 5.0 at?

spray

Close LOL!! Its Vince! No sold the LT1 motor years ago. Traded it actually for the powerglide transmission in LTL homer/Bad Z's drag radial car. The little bugger has had my glide for 2 years!! LOL!! At least it held up to all the power he is making!!

Good info Spray. 452 seems a bit much for a bolt-on ls3, or that that normal?

spray

Honestly I don't know if 452 is possible or not. That is what the owner said. Mathematically I would say it seems a little high but I am a little out of touch with the latest in chevy land so I can't comment. The owner is a pretty straight shooter so...? This new technology with the valve timing is really different when it comes to trying to guess hp. The 5.0 (mine exactly) has a huge HP curve (huge average hp above the torque curve) from 5500 to redline. When I shift the car it loses like 5 rwhp (the difference in power between 7500 and 5500) so it certainly keeps trucking along. It never actually slides back into the torque curve on a shift. So it is really difficult to compare the power numbers with the Camaro SS. They are very very different but yet perform exactly the same. I will say this though....A poorly driven 5.0 will never ever win a race. You have to drive the car like you hate it!! ***** out or nothing. Bad shifts, Wrong gear selection, wrong shift points and the thing will fall flat on its face. It has to be in its sweet spot or the car is a stone. The average driver with a 5.0 will never get its maximum performance. He just doesn't have the skills to make the car perform.

I guess it could make that with all bolt-ons..... Hell I'm gonna be lookin for 420+rwhp (after the addition of a fast 90) with a crate ls6 rated @405 hp. A ls3 is rated like 30 more so it could be possible.

spray

Its like the video at the beginning of this thread. I am not saying the mustang would win the race but the guy in 5.0 drove his car incorrectly. He needed to have that car in a lower gear at the beginning of the pass ( to be in the hp curve). He probably could have made it allot closer or stayed even. Instead he tried to use the torque of his engine to keep up with the SS. Bad move the 5.0 will lose driven like that every time. It needs RPM!!! Once each car is in their respective power bands I think it would be close. The torque of the LS3 is substantial in comparison to the 5.0 as is the HP curve of the 5.0 in relationship to the LS3/SS.

The guy in the mustang in the video lost before they even honked the horn and hit WOT. IMHO.

450 is high....a typical full bolt on LS3 sees right around 420 RWHP.

Cam cars settle in the 450 - 470 rwhp range.

spray

BTW my buddy with an C6/06/LS2 vette with kooks headers/X pipe and corsa exhaust and Fast intake/CAI/Dyno tune and some other small mods made 446 rwhp on a dyno jet. He beat me by 2.5-3 cars 3 out of 3 times (on his street tires) and went 10.88 @ 125 on a drag radial. Good luck with the LS2/6. nice engine.

Power under the curve/average HP advantage must lean heavily towards the Camaro.

JHL88

this is right on the money. and its the IRS if anything that kills the launch capability for the camaro. that and the low profile tires

5.0 does make more peak power fwiw

450rwhp with bolt-ons and a fast sounds like a blown up dyno number! The fast on a bolt-on LS3 has really not shown any gains because the stock intake works so well. He's not telling you the hole story... maybe his intake and throttel body are ported and seen a nice gain? Hes likely around 430... it would cool if he did make that without a cam though!

I think the big problem with the SS and getting out of the hole is gearing, and no one is putting gears in yet and getting some real testing! There is only one guy I can think of that ran a gear with bolt-ons only and he picked up .2 in his 60ft....( 4.33s ) ran 1.6 60fts and 11.7s! That shows what could be done with a gear and tires, the stangs come with the better grearing already! These car's bog down or spin and trying to keep the revs up is not easy without really slipping the clutch.

Word. I have 4 runs at the track and its a tightrope getting launched without spin, bog or wheel hop and then go thru at 110mph in 3rd. Love to have some 4.10's but GMHP just went 12.55 compared to 12.77 by installing a clutch and 4.10's. Not worth it.

Isnt the camaros like 400-500lbs heavier?

sweetC5

On stock rubber right? That .2 was the gear and nothing to do with the clutch thats for sure! The stock clutch is pretty good on these cars and some times and after market clutch can make things worse. I dont think a clutch would do anything for a mostly stock car other then having to adjust to driving the new clutch. Some sticky tires is were he could take advantage of the new gear and really work on that 60ft! What esle does he have for mods?
