What'ss the highest boost level for 93 octane?
 

safe boost level ?????

Wow... Care to be more specific?

What's your current compression ratio?

20-22 psi to be safe

assume you have a tbe

when boosting more on race gas, arp headstuds is recomended

I run 22psi personally with zero knock.

I run between 21-25 on pump gas, no knock.

22psi on 92 octane here. no knocks so far.

I have heard of people running up to 25 psi, thats a really thin line though, I try to run between 22-23 psi, make sure you get a fuel pump though, or your going to find out what fuel cut really is.

i heard anything above 24psi and you start to loose Turbo efficienty(sp?) on the stock turbo....some one know of this??

yea im running 22-23 psi daily

What mods have you done to your car? Your specific level of tune can influence knock resistance, and as a consequence, the amount of boost that you can run safely.

it all varies depending on mods and your particular car and fuel,

we have run the evo ix's 25psi on pump.. no knock...

cb
