super charger
My wife & I own a 89 vette.My question is.Would IT be worth more with the paxton supercharger rebuit (700 dollars) installed? It has all the same calloway options i.e ground effects louvered hood to cool the engine.

Callaway cars are worth what they are based on the name and limited production.
You can add enough parts to try and make a "clone", but it still won't be a Callaway or have the same worth.

No, it will be worth less. The general rule (for various reasons) is you deduct for performance - or most other - modifications. Superchargers are not plug and play, they need extensive other modifications to make them even halfway reliable, and even then, that's what you get, halfway reliable.

I agree, if you're looking for a well thought out and reliable supercharger for a c4, than you need to talk to Gregg at Blowerworks.

Okay, you convinced me. He should throw a $700 supercharger on a 24 year old car.

Thanks for the unbiased Callaway testimonial. And yes its true also that by merely picking numbers you can win the lottery, although its possible your odds might be better with Callaway. Just for a moment though, consider the original post about a 24 year old car, a $700 supercharger (rebuit), and resale values.

My supercharged 85 has survived the last seven years, i pulled the 170,000 mile engine to fit a new 383 engine with forged internals late last year to go for more boost.
The old engine was in great shape no damage to the pistons or ring landings, if it is set up and tuned correctly they are very reliable.
Still its not a good idea to go over 6 or 8 psi boost on a high mile standard engine.

My point exactly, as long as it's done right(as with any mod)supercharged vehicles are very reliable.

Wow!!! This certainly brought on some debate....I believe that I have made a decision and will not put the supercharger back on. Not because of value but because there are other thinkgs I want to do with the car.
I know that I will never recoup what I have into either of my vehicles, just wanted a litte input.
Thank you all.
