A Cummins ISX on the dyno.

A Cummins ISX on the dyno that was 100% loaded making 411hp to the wheels, the manifold is glowing red hot because this engine has power creep. The truck should only make 360hp at the wheels.

Nice!

The glowing is not due to "power creep", they will all glow red in the dark if the turbo is hotter than about 950 F, like at peak hp.

Way too hot for turbo. Id say just about killed it.
