Adding a point to compression in the 7/1 to 8/1 range inproves normaly asperated HP about 4-5%.

However, with this we have to give up about 3.7 psi of boost or about .25 bar. Going from a net of 1.8 to 2.05 bar is about 14% more HP potential.

That is say4- 5% more pre boost HP chasing say 10-14% plus on boost HP assuming the motor can operate efficiently with the increase in boost.
