Base pressure is 50 IIRC. I'm running a walbro 255 as a lifter from our custom fuel cell to our custom surge tank and then two 044 pumps out of that. I'd have to look up the IDC, but I have ID2000 injectors so it's probably getting up to 50-60% at this power level with the low rev limit.
Mikey I'll be curious to see how this works out. If I was just going to run drag passes I think I could get away with it for a while with careful monitoring and tune tweaking, but I'll only be running a few drag passes with it. I'll mainly be running it around road courses so it will be taking sustained abuse. Regardless of how this holds up in the near future, one of our built shortblocks is going in because the stock shortblock is a ticking time bomb at this power level.
