Supercharger information
I need some information about superchargers. I want to supercharge my 1999 GMC Yukon 5.7L engine. First off, is it true that it is safe for a stock engine to have 6-9 lbs of boost? And second, does a 160 degree thermostat help prevent detonation? Your replies are appreciated.

I think this is probably the best site to go to when you want to find out what you need to do for a supercharger. I don't think 6-9 lbs of boost is ok on a stock engine, the website says around 3-4 lbs of boost.
http://www.blowerdriveservice.com/recommend.htm Tells you everything you need to do and how it will help your engine and supercharger perform.

HAHAHAHAHA oh my shit... This site has the biggest number of delinquents and idiots I've ever seen. You've no clue how much time I spend laughing at 60% of the posts made on this forum. I think of AF as more of an Entertainment place than a Automotive Information meca. Seriously now, how often do you read something here that makes you go "hmmm, well gee golly I never knew that..." This isnt a flame at AF at all, Im just saying... AF in general isnt the most Educated place on the Web. Startin WIF ME!

Well, you're starting with the 350 in your Yukon, right? You engine has 9:1 compression and cast pistons. I would say 3-4 psi boost would be about as much as I would push.
If you get a set of 8:1 forged pistons, 10-15 PSI shouldn't be out of the question. Add a rising rate fuel pressure regulator, and you're in business. Then you have to worry about the strength of your crank and rods. The crank should be good for it, but I wouldn't trust the rods under that level of boost. Considering the cost of a blower, a set of pistons is not much, a couple hundred. You're basically paying $2000-$3000 for a 4 psi, or an extra $400 for 10 psi. If you really want to get into this, get a forged crank, rods and pistons. You can get a nice 383 kit with all forged components for a bit over $2000, and coupled with the blower, you'll be making 500+ hp.

That is the direction I would run. My brother had a 94' GT, that was his dream, so live it for him!

No problem at all, and I stand by my statement.

Well, now re-reading your original post I see that you were refering to the Site that you posted as being a place for information. I thought you were stating AF as the best place for knowledge on Supercharges and such things. My mistake. Whoops... but....
I was refering to AF in general, not just Street Racing. And My original statement still stands... Hope I didnt offend you.

 This is of course a great time to replace the cam while the engine is upside down on a stand. You can buy everything as a kit and have a local speed shop build it for you. I agree with Redneck, you get a lot of people passing through here who don't know wtf they're talking about, and I wouldn't want to take advice from them.

Like me for instance. I know about certain cars and such. The rest I leave up to the other guys.
