-16 to -19 , 8:5.1 , 160 psi all 6 cylinders compression test.
I did put a .098 MLS HG on with the lower compression pistons and the compression dropped to 130 psi.. I lost some spool up and power. I think this was supposed to give me a CR of about 8:3.1? Im going back to the stock thickness MLS HG

* Im also curious to what kinda of Compression #'s people are getting with thick HG and/ or lower compression pistons?

I have a VAC mls hg, .140"(8.9:1). Compression reads 142-147 psi.
I pull about 17 or 18 inches of vacuum at idle.

I'm running the VAC motorsports .140" gasket on my Technique Tuning Stage II turbo kit and i'm registering -20" with my DEFI boost/vaccuum gauge.

My car pulls 17-18 at idle I thought this was kinda low but after some research I found this is about normal for my set up.

after urbo charging my car i see alot of smoke coming from my crank case breather. i put my hand in frount of it, and it's isn't oil or anything. just vapour. dosen't even stick to my hand. my hand is dry. i jujst can't remember that when i was n/a. dose any have this happen to them.

i had a catch can on the car. but i was reving it with out the can on and thats when i seen the smoke. i'm going to put the can back on and see if it builds up in the can and how fast.

Maybe you're leaking coolant into the oil and what's coming out is steam?

I'm not sure what my consumption is, due to other issues I haven't been able to drive the car as much as I would like. Consumtion is low, if that's what you need.
