I was just wondering if a stock LT1 could handle around 8 or 9 PSI? I have an opportunity at getting a Turbo setup for cheap and I was wondering if I could handle a low amount of PSI. Any input is appreciated! Thanks, Tyler

 

More like 5 maybe 6. 9 or so is not a low amount of boost. It's not a 4 banger ya know

Depends on the tune and how the system is setup. If you're running an intercooler and an alky kit with a good tune and good gas, it should work ok for a while. If not, well... you'll probably find out what a shattered ringland looks like. Either way you will end up rebuilding it sooner or later.

 

i can show you pictures of 2 stock motors worth or destroyed ring lands. running a 5-7# spring in my wastegate. that was on a safe tune. these motors do not like boost much. it will be fast for awhile so have your fun while you can.

 

With the stock compression being 10.4-1 it is not set up too well for boost, if you intercool it and keep the heat down you may be able to run a few more pounds than a non intercooled setup.

 

I ran a 7 psi Turbo Tech kit for about a year and a half before I broke one ringland.

 

Thanks for the info. I think I'll steer away from the turbo at this point in time. I really don't have the money or time to rebuilding my engine. Thanks for your help!

 

Is the ringland part of the piston?

 

Why yes it is, it is the metal in between where the ring grooves are. I actually broke the one between the first and second ring.

 

Why Thank-you very much, I had the idea of what it was, just wasn't quite 100% sure.

This is a stock GN hypert. piston. You can see what the ringland looks like pretty easily. The reason these hypers last down into the 10s in TBs is due to the reinforcement ring buick pressed into the top to strenghten the ringlands. Makes for a strong, light piston. But forged are definitely better though.
