I ran WITH knock sensor enabled, no signs of KR on 89 octane, once in a while you WILL see knock on dyno but not on water but not very often.

Boosted, biggest pulley (3 1/8). I think the crank pulley is for a 3.3, sees 7.5 psi boost around 4000, tapers to 7 by 5800.
724 ft lbs tq, 753 hp, 9.5 cf at j607. Going to try next size smaller pulley, my dynos rated at 1000 hp, at 3500 the brakes not controlling the 700+ft lbs of tq once its hot so might not work.
fashioned a air duct to get cooler sir to tb, was seeing 120+degrees intake yesterday fwiw.

Picture of dynorun printout w big pulley

I
2 7/8 pulley (medium) thru mufflers, made 9.55 lbs boost, a mefi3 boost multiplier table ends at 7.35, went from mid 11 afrs to mid 12s, owner does NOT want to try little pulley, i dont really feel like rewriting tune anyways for a pulley he's not going to ever run. Thought about pulling mufflers, would defiantly need more fuel, would have banged 800 then. Saw 800 on depac (the frc, ie, friction factor adds a little fwiw. The bore is wrong on printout, oso wont let me edit photo, i just saw it rereading it, still learning new software

Ffixed the printout, it reverted to a different bore from a std file from previous 502

Thats impressive........Whipple claims 750-775hp with the 3.3 on the 525 EFI.............with a cooler....8-65lbs injectors in the rail

this has 2 80 lb injectors and 8 42 lb injectors, total of 496 lbs, the 8 65s comes to 520. This cam is better than 525 efi, heads are ported but less cubes. I bet the whipple on 502 525 makes a bunch more tq too

we also saw 9.55 lbs boost with med pulley, with this dinky innercooler i wouldnt be inclined to put it in boat with that, saw 58 celcius intake temp

What do you think the fuel efficiency is compared to Roots, Procharger/Vortech, Whipple? In between roots and Pro/Vor?

whipple fuel consumption sucks in my opinion. Bsfcs at 11.5/12.0 afr were in mid
.600 to close to .700 during these runs. I saw bsfcs on dyno w procharger closer to .500 to .580 so were talking 20% more fuel. Now, did adding the extra injectors before blower like a roots carbed motor fire hosing fuel in hurt bsfc, prob but didnt see kr even in the 9.5 lb boost run at 12.5 afr so its giving some latent cooling i think.
