When the throttle was blipped at the end, I jumped clear out of my seat! It looked like the tachometer was pegged during the blips, but I guess not possible to hit 8 grand.
It easily goes to 7000 (last throttle blip) but, that's all I want to take it to. I'm guessing the peak hp should be around 6,500-6,700...about the limit of what the intake and 920 heads are.
