What about when you factor in straight 272's into the equation...The powerband gets shifted higher, what RPM is everyone shifting at with this setup?

 

I have been shifting mine at 7650-7800 rpm area. But I have a dynoflash so my fuel cut and rev limit are moved up . I did a couple runs with my HKS type-1 turbotimer with the 1/4mile readout and I have been traping 2-3 mph more at 7650-7800 than I did at 7200rpm . My traps where in the 111-112mph on pump . I have buschur stage 4 with 272's and a few more other goodies. My ATS twin is broken in now so ive been practicing alot more

 

I think it would be good to shift a little after peak hp that way your rpm doesn't drop too much and get little hp and can keep some of its hp/boost.
