hey everybody i know are engines dont like superchargers because of the high comression. . .but now how can you lower the compression so you can slap a supercharger on the lt1.. .because i have the funds right now to get s/c but in the future i dont think im going to have money for a rebuild for a long long time . . i have 85,000 on the car and i herd that lt1 will only last 30,000 if your lucky with as/c is this true??well how can i make the engine last?? thanks for checking out my thread

 

man no way if you go wiht a nice mild set up liek a 4-6 psi s/c you will be fine just have to do some tweaking to your fuel system..it's when you get to the big boys liek a 8-9 psi s/c and are running unitercooled you need to check you head and your engine will get messed up good style fomr detonation

 

well i plan on going with a small s/c powerdyne 4.5 dont bash me i know folks on here dont like that setup . . but im goig with it . .its cheap and not to bad for the engine . . you think the lt1 will last??

 

ahh man whatever i would d the same less hastle less to worry about well yeha just check the applacaton and you will have to re-do some of your fuel system new pump ect but yeha if you take care of it and do all the proper maintence stuff you should have no problem man best of luck let me know how it works when i get the cash im gonna be doing the same you got the set up i want the y2k's and everything haha

 

ttt

 

will my lt1 handle the 4.5 ??anybody running with the powerdyne??

 

Dont waste your money on a powerdyne. The whole goal of this is to go fast, right?

It is all in the tuning.

I've pounded the crap out of my motor w/ just 6psi. My fuel is there, and my spark is certainly where it needs to be. I expect my car to live forever. But- I'll never know. My new motor goes in this winter!

run a mix of race gas and pump gas and very good tuning is about the only ways to keeping it alive. 85k is a lot to throw boost at. I would be very careful, your not going to able to beat on it.

 

How about dropping the Dynamic Compression Ratio with a cam swap? It will help a little. But the static compression really gets those temps up and the hypereutechtic pistons are fagile.

A 4.5 Powerdyne will get you somewhere in the neighborhood of 110 HP. Nitrous kits will net you more power... it almost isn't worth a supercharger unless you get above 8 PSI and more. Personal opinion.

 

nawim cool of nos im anti nos lol . . out here in cali thats a ricer thing . .imma just go with powerdyne for now then go with heads and a cam
