all I wanted to know all the Turbo and SC guys. what compression are you using right now and what fuel management are you using? i wanted to know how many guys are running stock 10.6:1 compression? how is boost and daily driving?
Also for who went from stock compression to a lower compression. how is Daily driving since your compression is a little lower, how is the power at the bottom of the power band? im just wanting to know. i have a civic and im trying to deicde on what compression i want to run. right now i like the idea of having 10.5:1 compression. I dont give up power down low but i also have turbo up top. yes i know tuning is key if your going to run that high compression.

 

First decide on your budget, and go from there.
It's not just the compression ratio, but more of a problem of cast vs. forged pistons and tuning.

 

well i boosted on 10.6:1 it was sickening , thne i built a block for 9.8:1, and i was really impressed and suprised, im getting a new shortblock this week that 9:1, i am really suproised ther power that was amde form that too even at low boost.

sickening in a bad way?

 

Definitely no more than 8 or 9 lbs on your stock internals. Take it from me....i fryed my b16, it was due to a whole in my actuator line but i still wouldnt run much more than that. Listen to what every one is saying though. Forged everthing. And yes tuning is very key.

 

in a bery good way , i made 295whp on 8psi on the 1st tuning session , full exahsut and no timing in it yet. i pumped it up to 11psi stock bottom and ran like a champ .

Well my bottom end is built and so is my head.

 

all mota powa!

 

guy locally runs 10.5:1 on his fully built gsr. hes makin almost 600whp on about 23psi and soon to be upped to ~30psi after he upgrades the stock fuel lines.

at 23psi he's running race gas correct? What psi does he daily? could you tell me about his setup a little more?

 

yea he runs race gas. its still a street car technically but it doesnt hit the streets too much. the low boost is 12psi b/c thats what waste gate spring he has. he cant go lower than that. not sure on the specifics of his setup but its FULLY worked over

 

ok great. anyone else boosted?

i your bottom end is already built , why are you concerned with the compression now ? just stick with what you got.

 

just wanted to know. I have a dart block.

 

im running 9.3:1, and the low end is still plenty strong.
