Thanks alot guys I dont see how I would lose power by switching to a 59 A/R the reason I didnt make anymore power this time was because I ran out of RPM the curve was still going up at 7500RPM.
This Turbo is not even at its best til 15psi at 10 psi its not even hissing. Hopefully John will email me the chart.
we also let off at 7000 the third run because the EGT got to 1350 f.
Is this high ? many other turbo car owners avg. 1600 f
