What is the highest compression that anybody is running on the street with an LS motor and pump gas?

 

I am running 11:1, but I know of others running higher on 93 octane. I will say, under load in 6th gear around 65-75, I get minor pinging.

 

Dont know, sure its easily 11.25 to 1 at least.

 

Hell I am sure people are running WAYYYYYY higher than that...

The LS2 comes stock at 10.9:1

 

There are alot of guys running around in the 11.75:1 area. Not great in extreme heat and can be prone to knock if the tune isnt pretty good. 11.25:1 is enough for just about everyone to make good power on pump gas. Why push it to the max for 10-15 extra hp?

12.04.1 here on 93 pump gas we have drove on very hot florida days with out any KO but with that being said i run a healthy cam witch helps the DCR and makes all of this possible

 

My new setup will be 11.8 to 1.. running on pump gas.

 

i was 11:7,when i get up again it will be right at 11:9 . dcr is where it's at, at 11:7 i was 9.0, at 11:9 i will be at 8.7x with a slightly larger cam.

 

same i am running really close to 12 with 0 KO but i live in MI and my evans pump keeps me around 170ish
