63, that's pretty sick. I take it you sacrifice some low-end for that speed crash?

No, the axial has much more mid-range torque, even though the powerband falls off fast, it still makes a little more power than a Vspec.

For an offroad engine a good .28 always makes more power than a good .21. Displacement. The powerbands tend to be more peaky though with quicker fall offs, but they make more power just about every except for getting past 30 or 35krpm. But even then the .21 offroads fall of the power band quickly after that.

The trade off is fuel economy, I haven't seen a .28+ that doesn't gobble up fuel. My Rossi 528xr made tons of power and would pull some insane RPM. With a 15t clutchbell it had seen 57mph in a nearly 11lb LSP-R truggy with tons of KHZ on it. When I put it in the Jammin truggy, which is much lighter it was far faster.

Still, if I was nice to it, I could eek out 7 to 8 minutes a tank, and balls to the wall in an open field I could guzzle a 150cc tank in 5m or less.

There comes a point though when there is too much power for a track, and the extra power is wasted because it can't be put to the ground. Which is why good .21s are so popular, even in the Truggy classes. Fuel economy is a big bonus.

Course, for bashing, I really don't care about how long the tank lasts, so its a hot mod 528xr in my Jammin CRT. mash:
