I was wondering what would be the gains of pulleing up the S-trim from

6.66/2.95 to 6.66 2.75... RPMs are as follow.. 46200rpm and 50116rpm respectively..

I only see 8psi with the first combo and made 555rwhp with it. I will take it to the track tommorrow to see how it goes with that power... What would be my gains??? will I loose with the S-trim by spinning it that fast and killing efficiency up top???

I want the fastest 150mph sprint possible... Thanks
