Hey Float,

I know your running either 9.1 or 9.5.1 pistons in your motor. My question is this, when you do a compression test do you get a higher reading than you normally would with standard lower compression pistons?

Hope that makes sense!

Yeah, youll get higher numbers. How much higher I dont know, but I would guess somewhere around 175psi for the 9.0:1?

yea 190, that sounds more like it.

Im seeing 145 across the board, but it doesnt smoke under boost or decel. I think I got me some 8.1 pistons......leakdown test tommorow will confirm I suppose.

time for a 2871 with the .64ar

Someone please buy my MINT s15t28.
