a fantastic 409whp at a mere 12psi, at 17psi, it made giant mid range power. top end dropped off because the injector size are too small. we should've gotten 750cc injectors, but no one expected this amount of power at just 12psi. 486whp could've easily been achieved with 750cc injectors. possibly just a little over 500whp. another problem was due to clutch slippage. again, no one expected these numbers. so a stage3 exedy clutch was opted for. now we have to get an exedy twin plate with flywheel.
