86 blazer turbo
 

i have an 86 s10 blazer slammed on the ground, i put a 3.8 liter 229 ci bored .40 over edelbrock aluminum intake, mild cam, and stock heads, edelbrock 650 cfmi was wondering if this motor would handle a 16g turbo only using 8 lbs. of boost.

thanks

What are you running for compression ratio?

thats just it im not sure but the pistons are just cast they're not forged or anything. so im not sure what its compression is.

thanks

You really should try to figure it out even if it is just an estimate. If you are looking to run 8psi or more, you need to be down around 8.5:1 CR or you'll be putting some mighty expensive gas in!

how would i find out

RE: 86 blazer turbo
 

Head/piston/rod/crank specs would get you close.

If most all of those components are stock, you are probably looking at 9:1 to 9.5:1 CR. Depending on programming, you may be ok, but you would definitely have to get a good tune!
