I'm curious on two things. Who are you guys running for boost gauges for your superchargers. Also for a DDM supercharger is the center fuel rail needed does it make a big difference in performance and reliability. Thanks in advanced for answers.
Boost gauge

I'm not using a boost gauge, and I have center rail fuel on mine, I wouldn't say it adds big performance to engine, but it does evenly distribute the fuel better to all 4 injectors and has a little more volume for a more stable fuel supply on long hard pulls, plus it looks great!

I am running Koso X-2 digital boost gauge along Shift Glow for other items monitored
The fuel rail by DDMWORKS is great for that added insurance of fuel on "Demand".

It seems like less than 350hp the rail isn't needed. But it does look really good.. I ran my Hahn with the stock rail forever. But once I changed to a forged engine I added the rail. And the rail has provisions for a return fuel line.
I have to add this.... I believe that thier have been engine failures because of a lean condition on one of the cylinders. Dave can tell yall about that .

As far as Boost guage for a supercharger you can go fairly cheap. You have a max amount of boost based on pulley size. With a turbo you could have a spike and you would need to release that immediately.

I think I want to do the fuel rail. No boost gauge though.

Typically on a supercharger install, we install the fuel rail to make sure we have equal distribution of fuel to all cylinders. We also rarely install gauges on the supercharger installs, unless the customer just wants to see needles move around, but typically there are better things to spend the money on.
Hope that helps,

Painter is putting my order together I will have him order one. Thanks

Sounds good, I am getting with him later today also. Are you part of the group up in Indianapolis that we are coming up to install?
-
Yes I am

@bjk81 I thought you were doing the big kahuna package from DDM. The big kahuna package includes the center feed fuel rail. The boost gauge is really not needed. Just had mine installed in Maggie Valley and love it.

That post is when I was trying to make a decision on stuff. I am doing the Big Kahuna.
