And just to clarify, a walbro gs340 is a 255lph pump.

I really wanna see how this thing runs out too. I've got a s366 kit I built we are gonna throw on my buddy's 6.2 Denali daily driver and see how it keeps up. only looking for about 450 out of it. I'm gonna build another kit and max that turbo out on my LS1 shop truck and see what kinda power and boost it can make before it falls on it's face. Its got a big hot side so shouldn't be too restrictive there like a lot of the 65-68mm turbines are.

Dyno'd today. Numbers are coming when we can get the graph posted. Cam obviously is to large for the setup and bleeds a little boost off on top as a result. Steven realizes this though.

Thanks for posting Martin. Ill get with him and switch/stack some springs and see what it does on 12-14psi. I think it would make close to 600 on 14psi especially with that much timing.

The cam is large so it's affecting spool time. Mainly the overlap that it has and it's late intake valve closing event.
Reversion city right now until the piston speed becomes high enough to "break free" of that reversion around 5000rpm. Then you see power come in.
I call it "V-tech mode".

Gotta go at least 15lbs!

Top port of the gate is open to atmosphere. Bottom port is referenced to intake. He is just using a spring in the gate to control boost for now. He picked up the car today and on the street it makes 11psi. So obviously its making more power on the street than the dyno. Trying to talk him into a little street run between us when it dries up. Like to get some video.

Nice, I think once you get the new spring in it and get it back on the dyno it should come in a lot faster. I bet it is starting to blow the wastegate open quite early and making spool suffer.
