Has anyone "de-stroked" an LS1 for boost?

Right, that is why I said I was going with a bigger turbo. I will also use a big cam to kill some torque. I am starting to lean towards a LS7. I am very interested to see what a big cam will do to the torque in one.

BTW, turning 8000 rpm would require a dry sump system as well.

well have any of you seen or heard of brammo/spectrum 5 racing?
they built an ultima GTR for street racing. they used a LS6 that i think was bored out and short stroked! they said the top end could take 10Krpm!!!! but this was in a 2200lbs car with a tranaxle that could only take about 650lbsft os they went high rpm, high boost, high cost! but the thing still made 1300bhp at about 9psi or something! insane!
here is brammo's site http://www.brammo.com/content.php?content.4
and here is some more info (and pics) on the spectrum site. click on cars and then the GTR project! http://www.spectrum5racing.com
thanks Chris.

I think the stock pcm stops making corrections at like 7500, and it just keeps the same value at 7500 onwards. Not 100% sure.
For 9300 rpms you would need a solid roller and an intake manifold that flows up there. The only LS1 I know of that has gone 9300 is Judson's NA motor.
