just wondering if i can safley run 6 lbs or even 8 lbs down the road? most sigs i see have 8.5:1 CR. thanks

 

shouldn't be a problem - I'm running 6# on stock CR

 

hey, i didnt know you had a blower? what kinda times have you put up? any dyno numbers?

 

I ran 18psi on my engine with C-12 and a junky intercooler with no problems and compression at 9.8:1. It blew the heads off at 21psi though

 

blew the heads off!!!! well i dont plan on goign that high on boost!

 

I run 10.5-1, with forged slugs, and a proper tune. I run 7-10 psi after a intercooler. I ran with the stock compression 10.3-10.5/1 with stock hypercrap slugs for over 95,000 miles and many years. Can it be done yes, but as I said before, get a proper setup and drive smart and it can last a long time.
