561 RWHP!?
I'm going to have to buy the issue just to find out what OTHER mods they have... They must be runnin some tremendous boost.
And I hope they've built the bottom end of that motor!
10 pounds of supercharged boost is iffy, and 12 or more....
Well, I hope they have an engine rebuild planned.
