It's basically physical dimensions of the HPFP piston and chamber, you can measure the piston if you open it up.
Or just a "ballpark" percentage change of the piston area and then volume re-calculation will do, if you don't want to open it. Adjust later if control looks wonky.

Just calculate it, like everyone does

is this the right way for the  calculation
RQUAHDPK = ( 10 / 2 ) ^ 2  what dose the ^ mean when doing the calculation i tried but i didn't get close to what it should be


 for VHDP it would  be what RQUAHDPK =  then x 3.14 x 5?

^ means for example  2 ^ 2 = 4

X ^ n = multiply X with X self for n time ...    4 ^ 5 = 4*4*4*4*4

In your example ( 10 / 2 ) ^ 2 =  5 ^ 2 = 5 * 5 = 25

The  for VHDP would be 25x3.14x5= 392.5 dose that sound correct

Would SKHDPMX stay stock since it uses stock spring?

I suspect my posts have went "missing". I did post that SKHDPMX isn't anything to do with spring, it's the stroke of the inlet cam.

CDLs have 0.4mm more stroke than A and B series EA113s.
