Good to know. I’ve been screwing around with the water box/flow control yesterday. I got it up to a sizzle. But I didn’t think of putting a jet in line as well

The jet screws into the stinger inlet. They cone with a 120 I believe. Just check it’s in there.

So part of my issue was my enhancer. So I’m going to run a stock ignition until I can get my hands on zeel or tl. Does anyone know hoe much advance I can run my ignition?

Still tuning my novis 48s (ls1's) but am at 145 pilots, 125 mains, 2.5n/s and 19psi pop. Running pfp dry, total loss, pump gas, oem 155 with a skat 6/12 5mm cutback. Top end pulls hard but not quite happy with bottom end yet so going to bore my exit nozzle from 88mm to 90mm and see if that helps.

Did you ever open your nozzle to 90mm and did it help? Running a super similar set up at 87.75mm right now and feel like I’m missing out on a little on the pump end but also don’t want to go too big this early on in my tuning.

Not yet had some other issues to sort. Will be testing this weekend and if everything is sorted and nothing has changed will bore next week and report back after testing

I know this was already addressed, but peak fuel pump pressure
is ~7.5psi and idle is near 3.5 psi, no matter what size fuel pump
is used. You didn't list if your return line was modified, but if it
was not, I would expect it to load up on idle.

3.5 to 7.5psi from a small ~17cc weed wacker to a Mikuni high volume
pump.

My return is modified and I’m running a 60 main
