Great torque number on that engine, Brent...

[Yellow Truck]

It would be very interesting to see the charts.

[blykins]

The graph shows a hp peak of 6000, but I think the graph indicates more of what happens through the entire run, even when the operator starts backing off the water valve (it's a Stuska).  I would go by the tabulated chart; I think it's more accurate in this case.  This is a little cooler water temp than what I usually run, we were previously hitting it at 170-180 degree water temp, but we had cooled the water back down right before this pull and just went ahead and ran it.

Remarkable torque curve. I've been reading about the influence of primary header diameter on peak torque RPM. Not sure I understand it, but curious what the header diameter was on that pull.

This is such a cool build, I'm very curious what the idle was like.
 RPM, it work ok with power brakes?
