A) Yeah, that surprised the hell outta me too.

B) Not sure I understand what you mean by "throttle trim", but my understanding of it is that the two diesels provide a shit-ton of low end torque and then once up to speed, the blown nitro burner provides a tremendous amount of hp.


Well, the rig got rolling with a lot of noise and smoke from the two V-12's, but the butterflys on the V-8 weren't open.
A bit later, the V-8 throttle opens.

I'm assuming he pins the throttle on the V-12's, and uses the V-8 as additional (or not) as necessary.

Maybe the butterflies don't open far enough to notice until the v8's over 1,500 rpm and the diesels are getting over-revved.

A) There's tractor pulls outside the US? I'm stunned.

Interesting thought.  Diesels reach or are just above peak, the V8 adds some extra twist.
