LS3 Camaro with Bolt Ons

[68droptop]

I think someone will get one into the 10's NA pretty quickly, but it is not going to be done w/ bolt ons alone. Heads and cam for most people should put it in the 11's I would think, but I've seen a lot of different cars w/ the same stuff done to them run very different times at the track. It's all about who is working on the car, who is driving, and if they know their stuff or not.
I'm not jacking around with it though, mine will be getting pistons (lower the compression), heads, cam and either a procharger or turbo. That, I think, will put it in the 10's

Damn, I want my SS to sound like that vette. I hope 10's is possible on a NA H/C LS3 5th gen.

I've seen it particularly difficult to get into the 10s with a stripped 4th. Gen, with a big stick, big stall, big gears, and good driver. A car that weighed some 3200-some-old-pounds with the driver barely scratching 10s leads me to think a stock LS3 car, will run bottome 13s on street tires and low 12s on DRs and a big stick. I'd love better numbers than that, but a 3450 lb. 4th. Gen. stock, ran a BEST of high 12s on street tires, an those cars were making 310+ horse to the tire. The math just doesn't seem to be there...

Prove me wrong

With a full interior, possible on 20s if we can't find an 18" wheel to fit over the rear calipers? I think not. 10s NA with no power adders will be tough with the Camaro, just because it'll be weighing in at 3900 lbs race weight.

Okay, you can't compare a 3200 lb C6 to a 3900-4000 lb Camaro. It just doesn't work. If you want to compare it to anything, look at the whp numbers for <10.99 GTOs. Fully dressed they weighed much closer to the Camaro.

When your comparing you also need to realize where and when those times were achieved...a car that ran in late november at ATCO wont run the same times in GA in August...DA is your friend.

I would agree with LSxJunkie the GTO is a nice comparision as it the G8...unfortunately the GTO doesn't have the advantage of the LS3 and the G8 actually weighs more and no M6. Your gonna have to make rough estimates.

One thing about comparing 4th gens to 5th gens...Sure the weight will be more...there will be a host of launching issues d/t a new platform (suspension, wheels, tires etc), but although 5th gens are handicapped with more weight, you also have an LS3 and not an LS1. 500 rwhp cam only on a M6 LS3 is possible...no so on a LS1 and you've got 100hp more stock (if the old 10rwhp = 0.1) then the LS3 more than offsets the weight disadvantage of the 5th gen...not saying it has the capability of being a faster NA stock short block ride, but something to think about.

I was just reading up on the LS9. I didn't realize that GM started beefing up the LS3 in 2007 and even more in 2008, and ALL GM LS3 based engines have the heavier duty block that comes with the LS9 from now on. That's good to know it could handle the supercharger.

I also didn't know that for every pound of boost, that is a 7% increase in HP. The LS9 puts out 10.5 lbs of boost.....

[DGthe3]

10.5? Seems high. I figured it would be around 9 or so, which is theoretically 716 hp off of an LS3. Density losses from heat and optimization for supercharging should bring that down 10%, back to ~638. Guess those losses are higher than I thought.

here is where I was getting the 10.5 lbs of boost

Not sure what you guys think of their credibility. I assume I will shortly find out

[radz28]

I believe 'TWIN is right - 10.5 lbs. max' while the LSA is around 9 lbs. or thereabouts. I think they need that much pressure because of getting that intercooler to fit under the hood of the 'Vette too. It just seems the LS9's intake may be a little more difficult to push air through than the LSA; that's just my VHO though. I BET a crate LS9 is pretty underrated though; I'd like to see what a good exhaust system would do to power numbers. I'm not sure how restrictive the intake side is, but I bet it could be improved.

I also think I remember reading that for every 10 degrees F cooler you get he air, it is 1% increase in power....that's why cold air induction is so important with or without a supercharger.

I think I got that info for BANKS

Yes, I'm quoting myself but here are a couple vids with Mr. Bank's take on FI and CAI.

Hopefully You'll enjoy it.

I really enjoyed his take on the future of musclecars. Very cool.

the block may be able to hold a s/c, but depending on the amount of boost, you will need to go to forged internals like with the LS9

nope, 10.5 is the set max for the LS9. and 9 lbs is the max on the LSA tho, im sure there's plenty of ways around that....lol

the LS9 s/c is also bigger than the LSA. something to keep in mind as well.

I'd love to see some LT's on an LS9.

[TLSTWIN]

Yep, SPEED. I also thought the thought of the future of the muscle car was interesting as well.

My biggest beef with a diesel has always been the sound and smoke. I loved the way his race truck sounded and NO SMOKE

I would be game for that!

How about his street legal 200+ horse twin turbo firebird

sorry for the
