Is there anyone here who has lowered the compression on their engine to 9:1 and drive the thing on a regular basis. I see nigel got lower compression pistons, but is his car running with these yet. I am in the process of getting my engine built but would like to know what it feels like to drive a maxima with lower compression when not boosting. Will the power loss be that dramatic?

 

you plan to drive aorund n/a on a lower comp block?? power loss will be noticeable, but will that even work without tuning??

 

But he is boosted, so he needs the lower compression.....

 

right, meaning when you drive around and are not punching it and boosting. just when you are tooling around town. Yeah i know all of our roads are wide open, but still i wanna know .

For the short time that i have had the turbo, i didnt really feel any turbo lag, but I want to know if when i lower the compression will i be smackin that horsey waiting for the turbo to spool

 

I know hes boosted...I read it wrong though, but in his first post he said-->

"but would like to know what it feels like to drive a maxima with lower compression when not boosting"

I thought maybe he meant how it would feel if not boosted, like say he was going to be driving on it for a little bit with the turbo not installed. didn't know he meant when not boosting or just cruising I got your email Corey, give me an hour

 

I've thought about this and I think I would rather have a higher compression ratio and lower boost pressure than the other way around.

But that's just me and the kind of driving I do. I ruined the driveability of a motorcyle I once had by moving the power way up into the high rpm range. It was a kick in the pants that 1% of the time at high rpm, but it was a dog cruising around town. So I'm wary of that now.

 

How are you lowering compression, if you are doing strong lower compression rods and pistons, just turn up the boost.

 

you'll lose around 30 HP throughout RPM powerbands.

FYI, 300zx TT with no turbo (blown, vacuum leak as usual, turbo seals bad, etc etc) has around 165 HP.

and RAMIUS83 (Errrik), did you lower the compression? if so, how?

 

Erik has not lowered his compression

 

thanks pmb thats exactly what i wanted to know.
