Anyone else running tubes this big on 1050-1100 hp range. My dad’s combo has 2 1/8 to 2 1/4 w/4” collector, smaller intake plenum as well & made roughly 80 ft lbs more trq.

Not completely, last year I had a brain fart while adjusting the close rate on my throttle stop. I left those numbers in so it only stayed closed for .5 tenths of a second @ 3800 rpm. It went 8.69 @ 159 lifting after the 1000 ft. Air was roughly 4400 ft.
