Whats wronge with pulling your pud? Anyway back OT… My trained eyes have built in flow benching software, and I say those manifolds will flow 342CFM @ 3340RPM with an egt of 1201F thus putting the turbochargers efficency range at a 2.34:1 ratio with the igntion timing of 23.5 degrees. Should dyno, in FL, at 865WHP and 654Flbs/Tq, with 285-35-R19 Mt street scramblers red compound, directional tread on 31Psi @141F tread surface temp, with a given ambient air temp of 78F on C16 fuel, with 18psi of meth injection at 45% throttle input to redline.
