Boosted_B_Series

I need a little help and need to roughly calculate my compression for this season.

I have a few things in my setup that changes compression a bit.

Please correct me if any of my figures are wrong.

My setup:
ITR head
High compression skunk2 valves
GSR Block
LS Crank/Rods
GSR CP pistons

If my maths right:
High comp valves add + 0.4:1 compression
GSR CP pistons with LS stroke add + 0.5:1 compression

So If I use 9:1 pistons I land somewhere in the 9.9:1 compression range.

I do not know any rough calculations for the ITR head on the GSR block

Any insight, comments or suggestions on this will be greatly appreciated.

Thanks for your time,
DK

just use a comp calc and type in the physical measurements you have
