Finally, my motor went.

I drove it around last night, the valve springs alone have made a noticable improvement in power above 6600rpm. With the oem springs the car was probably experiencing valve float robbing the power. The dyno will tell the story. I was going to do more work (cams, maybe valves), but I need my car squared away and dialed in for an event coming up. However, expect a good gain because this thing is going to be tuned for some crazy boost levels .
