Also this motor didnt like to run richer than 13.2-4 on 91 octane it made less power on 12.9-13.0!!!

I know about one member who gained like 20whp with 86mm 12.5:1 CR CP pistons.

So you got pretty basic setup including B18 Tri-y header, 3" exhaust, custom IM, N1 cams, 88mm 13:1 CP pistons and thats making 238whp?

Its time for standalone and ITB´s next year.

What are the numbers? I cannot read anything on those pictures.

I cannot see the axis of either graph, the maximum value, the correction factor, smoothing grade, etc...

Right but I thought he was doing mid 220s on86mm bore. So this means mid 250s on 88? I mean a little of the power is the added displacement and deshrowding of the valves just by opening the cylinder bore. I thought this build was in the 230s that's why I was a little confused

Car made with 88mm 300ZX pistons 209whp pretty much stock bore stock compression #'s
I made a couple of passes to get a baseline before I replaced the pistons I didnt thought that a old school piston and rigs could rob that much hp but no I believe it...
But seems like the bump in compression and better design piston are very significant!!!
