What really sucks is you spool at 4.5k and you only have till 6.5 before you redline... But that is some SERIOUS power!

The spool got alot better when I fixed the hole in the a/f chart, but I ran once after that on a different graph. The car was loading up until then but the numbers for the last chart were 500 rwhp/465 rwtq @ 19 psi with the a/f's at 11.5 across the board.

7m-gte/HKS 1.2 and ARP bolts

Blueprinted (and balanced) I believe means precicely machined so when they spin they are completely even and dont have more weight on one side of the axis than another, which would make them want to wabble. All it does is pretty much make em more reliable at higher RPMs and less likely to distort and spin bearings and such at higher power levels. If there is more please feel free to chime in.

Why is there such a small gain in power when going from 19psi to 26psi? 500rwhp vs 557rwhp ???

I might be getting to a point where the a/r on the turbine is causing too much back pressure. I talked with SP when I bought the turbo and they said in this configuration that it should do around 680 to 700 hp at the flywheel so I figure if I can get 600 rwhp or close at 30 psi I'll be happy and then I might change a/r's and go to a .81.

When I built the engine all the pistons, rods, combustion chambers and such were brought to the same weight as each other. ie all the pistons weighed the same, all the rods weighed the same and so on.
