Weird it was making 24 hp per psi going from 4-10lbs. Then 20 hp per pound from 10-13lbs, Then 28hp per lb from 13 to 15lbs! Does that mean the timing was probably not high enough at 4-13lb range? Or do you think the compressor wasn’t at its happy spot on the map in the lower boost levels?
Can you setup the boost to come in at X rpm (or MPH) with the Holley like you can with the MS3? Seems like if you could pour on the boost over 6k you could get your peaky 4 digit power level dyno number without pounding on it so hard at low RPM. Should be a lot easier on things if you only make “big” power well above peak torque.

Any regualtor will work with the right fittings. Head to your local big box (Menards, Home Depot, Lowes, etc) and grab one. If you can find a lower resolution (0-30 psi) would be best. I use one off an old air compressor, it just takes smaller turns, but works fine.

yes, it has 4 different rods in it, and 100K mile rings and a fresh harbor freight 3 stone hone

Hey denmah, in one of the vids you mentioned something about Cameron's fix that lowered trans. temp. Can you elaborate? I just ran into an issue with reduced flow to the cooler. Lost the trans. but hoping to avoid it in the future.
. Congrats! I wonder if it can crack 1K on just higher boost...
