GM put stronger tranny and internals on their boosted vehicles for a reason. I suggest make your engine and tranny stronger before boosting or go all motor.

AGP TT or LSA

And drag radials

As people are saying, it's not just as simple as psi, becasue of all the other factors. But I can tell you that a totally stock LS3 car will make 700whp at about 11psi on the AGP kit. On something less efficient like a supercharger or single turbo kit, that absolutely will not happen, so you can't really compare. Add with an aftermarket cam an otherwise stock LS3 could make 700whp at 9psi because it's getting a lot more air mass through the engine at less manifold pressure. Also a huge factor is the 60-80hp it takes to run a supercharger, turbos don't have that extra drag on the engine so that is free power to your wheels.

While technically speaking, you're right...I think these comments are confusing the hell out of the guy here. We are talking about a stock LS3 here and a guy who doesn't know a ton about modding or boost looking to add some to it. And when adding boost to a stock LS3...you want to be careful with how much boost you put to it. You know that Unreal.

kenny17,
It all depends on what you really want out of the car. If you want a kit that will deliver you the most HP on a dyno run...you can't beat the AGP Twin kit. But you will have a little turbo lag off the line. If you want to get down a 1/4 mile the fastest, then there might be better options for you. Seems that the centrifugal chargers like the ECS kit consistently post the best 1/4 times. And if you are looking for a street car, the positive displacement top mount superchargers (like the LSA or Maggie or others) make a pretty damn fun instant hit type of car.

Now of course...all the different systems can be made to beat the other. So you'll get the vendors and their fanboys touting things. And the truth is, they ar all good options. We're lucky to have so many great options for these cars.

Your best overall value power adders will probably be the ADM LSA positive displacement charger....or the AGP Twin kit. But there are many other options (Whipple, Kenne Bell, Magnusson, SLP, Edelbrock, ECS, Vortex, Hellion, etc, etc, etc). All have put huge smiles on people's faces. All have their place and do things just a bit different (power delivery, install ease, hp limits).

People need to learn boost basically means nothing. He can make 800rwhp at 10psi or 15psi. Same cylinder pressure.

So no, you don't want to be careful with how much boost, because boost doesn't matter. Cylinder pressure/power does.

I can see you need to stick to your guns here Nick. Like usual. And I aleady said...you are technically right. Yes, you can design some really messed up camshaft that will allow the LS3 to make 30 psi in the manifold and only push enough air through the engine to make 600hp and live just fine. But who the hell would do that? Not every thread needs to be about how to make 1000 hp and the technicalities that you understand.

The OP here clearly doesn't have a ton of modding knowledge...he's asking if each turbo produces 8 psi on a twin set up??!!! You think he understands what your saying?? And I'm not holding that against him. We all start somewhere. So all I'm saying is that he is asking about modding a STOCK LS3. And with the forced induction kit options that are out there...you absolutely need to be careful with how much boost you put to it.

A lot of your comments range from irresponsible to insane. We all know that you're an AGP fan boy. Hell, so am I. I have their kit and have had numerous conversation with both Ben and Kevin before, during and after my purchase. They are great guys running a great company that makes a great kit. You popping in to every thread saying things like boost pressure doesn't matter and 1k+ rwhp is a walk in the park really is doing them a disservice. Neither of those statements are true and make you seem ignorant, arrogant, or both. I also find it somewhat ironic that the biggest cheerleader for AGP on a Camaro board drives a supercharged Corvette. A little more self awareness would go a long way.

I understand his point but again a stock LS3 will not live at 20psi. Unless you are running race gas or E85 and one hell of a tuner not happening for longevity. Most folks are going to be running pump gas on their builds anyway so 20psi would be a risk I'm not willing to take.

[AGP Turbo]

It's this hugely critical concept that helps people think more clearly about how things actually work. The overly extreme numbers are part of explaining the concept. I thought this was a good discussion much like you find on more technical forums. Camaro5 has always been quit behind on advanced thought.

[jman123]

I made 678whp @ 8psi. e85 and a pretty big NA Cam.

[Gearheaded]

What you have here is one person explining why sticking to a PSI number is literally an old school train of thought, and the actual number is almost irrelevant; then a few guys refusing to let that thought go lol.

PSI is cause and effect, not what you base reliability on. Why is that so hard to accept?

The dude lives on the forums and always has to be right even if it means throwing out some ridiculously stupid comments. Does it on corvetteforum and not surprised to see it here.
