I did another run up to 7250 and I peaked at 6750 still. I'm guessing that at 6750 I'm just outflowing my aftercooler. I do have a dyno graph showing peak hp at 400.22 but it's not a nice pretty one like this so I didn't post it. There's pretty easily 410 in this thing. I've all ready got measurements on a bigger cooler core so I'm going to have to see what I can fit in there.
