Went to Rockingham Dragway NHRDA event and dyno'ed the Fummins.It did 563hp and 936ft.lbs. torque on a Mass Diesel performance Dynojet.A little low for what I have done.The AirDog 165 is set at 40psi,but as soon as you hit the throttle it goes to 20psi or less.I had the operator pull to 3500,4000 and 4200 rpms.The chart showed peek power at 3250rpms with torque little before that.I don't know what boost was or egt's.The smoke didn't clear up completely,but wasn't real thick black either.My set up is as follows:
98 180hp 12V,benched pump 468cc with 181's,but have 7mm dv's in it,5k,100 plate,AFC set at like 40psi full forward,Weston 5x.016,22 degrees timing,Maxspool 2.5 cam,63/68/.70 over 75/96/1.32,63's waste gate set at 18psi,.010 head gasket and o-ringed,ported head,dual feed,AD 165 40psi.Really was thinking power would be somewhere in the mid 600's.What's y'all's take on it?
