Guys,

Getting ready to head out late this morning, and I'm thinking about fuel pressure. As stated early on, fuel pressure has been ~38lbs at idle and up to zero manifold pressure, and ~50lbs once the transition into boost has been reached. This may change now that we have the stuck injector working properly, but in the event it's still showing low.....

ATI says boost fuel pressure should be 62-65lbs. I'm reading the manual, with instructions for adjusting fuel pressure, which I can handle, but it's not specific on one point: Is this adjustment only for fuel pressure in boost condition, leaving the idle pressure at ~38lbs, or is it for the full sweep? My setup has the ATI pressure regulator.

Thanks. Brad.

Gimme Fuel

ProCharger's fuel regulator systems are notoriously crappy and inconsistent. A great investment would be to install a good fuel pump, good regulator, and have a custom tune done. Talk with Smitty (Articfriends) some more. He has done many, will be great insurance, especially with a 496 engine.

Good luck testing!

At idle, with no boost (quite the opposite, under vacuum), you would expect the engine to want stock fuel pressure. The boost referenced fuel pressure is needed when you start building boost but not before.

Yeah I seen you got a Sierra.

Did you cut the old filter open?
I know it's least of your worries currently.
I just wondered if they were as chintzy as I remember inside.

Hope the injectors resolve everything!

Guys,

Oh my God…..

Smitty said it was going to be night and day. I can’t think of any other way to describe it. I don’t think the boat was running right when we bought it. It is now.

As I stated initially, we had propped down from a 28P Bravo prop to a 26P Bravo, trying to make it a bit more water sports friendly. The tattle tale said 71, but all we ever saw on it with the 28P was 67-68MPH. After propping down, the best I could get was 65, and that was at about 4700RPM or so. Today, we saw 71MPH, with the engine tickling 5100 (just shy of the 5250 rev limit I had Whipple set it to), and still had the top 20-25% of the throttle to go. I never put it on the firewall.

My wife got a video of the boat launching and throttling up, but the resolution sucks and it’s REALLY bouncy. Just suffice it to say it LEAPS on a plane, and the acceleration is off the hook.


I’m happier than I’ve ever been with this boat, and I was a pig in the mud when we initially bought it.

I need a bigger prop. Seriously….. Anybody got a 28P RH Bravo they are looking to broom? Maybe a 30? I may have to talk with BBlades about some lab work to a 28P it I can find one available.

Thanks. Brad.
