That's right boys and girls. If GM builds it with any type of forced induction, we will buy the first one and be the first ones to hit 500whp on the stock motor. People who know who we are know I'm not joking.

What are you talking about?

AGP Definetly has a good reputation in the industry... cant wait to see this car being modified! :)

Kevin; If you would, please talk a little about the merits / drawbacks when comparing supercharging to turbocharging and their application to a street car. Also touch on the strengths and weakness of each. Thanks

Here's an article about turbo vs supercharger that I found informative: http://www.superchargersonline.com/content.asp?ID=19

If you wanted to simplify the SC vs. Turbo argument, here's what I always use as a guideline.

1. Supercharging will usually produce more low end torque, at the sacrifice of top end horsepower.

2. Supercharging is not usually as easy to "crank" the boost. It requires a pulley change, belt change, and can sometimes be a bit costly depending on setup.

3. "bolt" in upgraded superchargers are not usually easy to find.

Just my 2c.

This is a nice simple explanation of the differences.

If we were only talking about running 8psi of boost then it would be a toss up. The SC would have no lag but the turbo would have no drag on the motor. But in our case we are talking about running 18psi every day and maybe 25+ PSI on race gas. A SC is just too far out of it’s efficiency range and would have to be geared to drag heavily on the motor to make that much boost.

What sorts of issues is one likely to encounter...say after 25-30K miles of everyday street use? (on either system) Are the turbo oiling issues after engine stop resolved? Any reliability issues from running 18 psi boost long term?

The old issues of turbo oiling problems are long gone. Any good turbo will live 100,000mi easy, I really wouldn't be suprised if the long term durrability is better than a SC now days. I don't of anyone who has run a SC for 100,000mi. w/o a rebuild, it may be posable but they seem to need rebuilt every few years. 18psi daily is no problem at all if tuned right.

Z1500 - Do you anticipate offering complete kits for FI, or will your goal be more of creating "one-off" cars for racing applications? (Perhaps I just didn't find it, but I only saw individual parts for turbo systems on your website)

Thanks for the info.

We'll have a complete bolt on 500hp kit.

Would it be better to snatch the the first Solstice with the 2.4 ecotec or wait for the later one with the super or turbo charger allready on it. I only ask because I wouldnt want to make a bad step early on.

I'd wait and see what the NA solstice comes with, in terms of engine internals. In the past some NA ECOTEC engines have come with powdered metal connecting rods which may only be good for 280 hp or so. Supposedly the turbocharged/supercharged ECOTECS showing up in Saabs and Saturns have forged rods.

The other big problem is the compression ratio. If the NA comes with a CR of 10-11, you won't be able to add much boost easily. You could swap in a new rotating assembly, if need be, but that's not exactly a bolt-on mod. :) The forced induction version, when it comes, will probably have forged internals standard and a much more boost friendly 8.5 or so CR.

So, to answer your question, wait and see what the production NA version has engine-wise before deciding. I'm probably waiting for the turbo/supercharged version, but who knows.

Thanks I figured I would wait but since its still kinda up in the air whether the car will have a turbo or supercharger on it I didnt know if it had a supercharger on it rather then a turbo would it be more of a pain when bolting on the turbo from the company posted in here.

Good question. IMHO, if we say that going from NA to turbo is 100% effort, than going from supercharger to turbo is maybe 20-30% effort. That's effort, not cost :). If the production Solstice comes with a supercharger instead of a turbo, it will still be fairly straightforward to remove the supercharger and add a turbo kit. By virtue of the supercharger from the factory, the car will already have:

* Forged internals (hopefully, this is the big one)
* Ignition/fuel maps in the engine computer for positive boost, and accompanying sensors. Hopefully we can avoid having to go stand-alone.
* Upgraded fuel system (bigger pump, bigger injectors, etc.)
* Intercooler (maybe)
* Bypass valve (maybe)
* Hopefully, enough room to add necessary plumbing once supercharger is removed.

What you'd need to add then would be new exhaust manifold and turbo, some manner of boost control, some intake plumbing, oil lines for turbo, and some tuning. Oh, and an idler pully or similar set-up to blank out the supercharger. Even for factory turbo cars, a lot of aftermarket upgrades use a different turbo and exhaust manifold. I'm looking forward to details on the boosted version no matter which route they go. :)

Stephen has really nailed it pretty good.
1)
I wouldn't even consider buying this car if it were N/A.
2)
If it comes supercharged then it will be expensive to upgrade to 500hp because it will need soo many parts to install the turbo and replace the supercharger. But at least you can sell the supercharger for a few grand to cover some of the expence.
3)
If by the grace of god this thing comes with a turbo from the factory. :eyebrow: 500whp will take about a month.

So basically forget about the NA motor and Pray for a turbocharged motor but if it has a supercharger instead its not the end of the world
