I have taken the time to read this entire thread. If I missed anything, I apologize, but I have a few questions.

First off, thank you for taking the time to explain your area of expertise. I am torn between Supercharging and Turbo-Supercharging my Camaro.

I have an SS with the LS-3.

You mentioned the cooling of the Turbo system by undercar air flow. Are the turbo's in your system mounted under the car at the exit point of the exhaust manifold, or are they mounted at the rear?

I read where with a properly sized system, there is relatively no "turbo lag." Can you explain this a little more. I am very intrigued by this.

My next question has to do with some of the dyno graphs that have been posted. It seems that unless I'm reading them incorrectly, there is a huge in-rush of power, starting from near idle up to around 5000-5500 and then the powers drops off. Is this common. I was under the impression that Turbos created power up to and beyond the RPM capability of the engine. Is there something in the way the boost comes on that reads differently from the "blown" engines on the Dyno. The blown engines seem to make torque hard and fast and build HP all the way to or almost all the way to the red line. The charts shown here seem to show the turbo engines climbing abruptly and then peaking and dropping back off...

I know there is some professional difference of opinion related to this, but at the same relative boost level, if a turbo system provides more net gain, is there any relative difference on the long range strain on the engine? Would it be prudent to go ahead and put forged internals in the short block, or would that be un-necessary at moderate boost levels? Is it recommended to put a fuel booster or different injectors on a supercharged engine. I would not want to lean an engine out and risk breaking a piston through ring binding against the cylinder walls....
I never really knew the way a waste gate worked until reading this thread, and a question related to that is is the waste gate adjustable in small increments at any time or is this something should only be done during a dyno session? For example, could you have a hand held tuner and
"adjust" the waste gate from say 6 to 8 lbs of boost and just plug in a different tune....I guess if would be a boost on the fly so to speak...

I've ridden turbo'ed motorcycles and they are amazing, and therfore I am leaning a little towards a turbo system... I'm also a fan of sleepers. To me there is nothing more satisfying than knocking the smirk off someones face as their much more expensive car is suddenly trailing far behind a car they just knew they could smoke.

If I was to buy one of your systems, do you have a recommendation for an installer you have used in the Central South Texas area. I live between Austin and San Antonio... I'm still a couple of months away from purchasing, but I want to have my ducks lined up when the time comes...

I apologize for the long post... but really want the information from someone that has been there done that....

Anyone else with arguments for something else, or supporting information, feel free to chime in...
