Default Norgren regulator - anyone using one?

This guy: Pressure regulators R07-100-RNAA

I plan on running an MBC until I'm motivated enough to sort out the EBC on my MSPNP. So ... has anyone used this regulator before? I assume it's a bleeder unlike the Hallman/turbosmart variants.

This regulator is meant to control the line pressure between an air compressor and a tool.

What leads you to believe that it would be suitable for use as a boost controller on a turbocharger?

There are many inexpensive ball-and-spring boost controllers which would be entirely adequate for your needs.

I have a couple of those at home, work good for pneumatics on robots an ****. Never thought to use it as a boost control device. You put as much pressure as you want on one side (within reason) and on the other side puts out what you set it to.

Because it is what Turbonetics (and others) use in their MBC kits.

now if you used a relief valve inline before the pressure regulator, you'd be in business...

what sort of business? I dunno.

This is the exact opposite of how you want a conventional boost controller to work.

This is what some people are doing (though now you're into it for $$)

Which is why I'm somewhat confused as to how it works.

this is why i asked if you had an EWG... the keyword is: pressure differentials.

I've got a Forge IWG 'can' which can be converted to a dual port IWG (has an NPT plug on the other side of the piston).

Thats true. The IWGA I have on my EFR is dual port, so its not just ewg's with dual port.

It limits the amount of pressure which is applied to the "other" side of the can.

IMO, the performance of this device is likely to be inferior to that of a ball-and-spring unit, inasmuch as that the system as a whole will retain the gradual opening characteristic typical of "conventional" wastegate actuators.

okay, you'd basically "tee" the upper port of the wastegate and the regulator from the boost source. then from the reg. out, to the lower port. I vise versa, i dont want to think too hard.

since the dual ports work on pressure differentials, you can now tune the difference of boost above and below the diaphragm and control the level in which it operates.


think about it this way, you're using the top port only currently, right?

Boost enters, it pushes the diaphragm, the rod extends, the wastegate opens.

if you put the same amount of boost on the lower as the upper, then the wastegate does not move, since the boost cancels itself out, and the diaphragms defaults closed.

now, if you put a regulator inline, and put in more boost up top then below, you'll reach a point where the upper pressure can overcome the lower + preload and the wastegate will open, just not fully, i.e., MOAR BOOSTZ.

tl;dr: brain = smart.
