Thank you again for correction. So, 25 hp is what we needed to set for std engine, than modified could be 33-34 hp from crank.
Yes we tested both std, but one new earlier this year with 27 hp, other little used, just month ago 27.7 hp.
We didn't change blowdown, but rise cylinder until mid range started to drop. This gave 1.2 mm base.
