I am looking getting a new Rising Rate Fuel Pressure Regulator.
Am running 60 PSI base.
What are you guys using?
Thanks.

 

depends on fuel pump.. But the best i've used are Weldon..

 

You must be running ID's?

On the same note, what's the highest base pressure you can run on EV1 Bosch 1600's and still get good spray pattern/atomization?

 

Yeah....4 X ID2000's and 2 X Bosch 044's.

 

I am running a Weldon regulator, with 75psi base.

 

i ran a 50 psi base pressure with my bosch 1600 units, now going to 75 with me bosch cng units , aeromotive 1000 black top 1:1 was used with the 1600 injects , but im not decided either way on the next unit, thinking hex drive aero unit , meh

 

If your budget can afford, get the Kinsler piece, otherwise the Weldon.

 

I've had the 1600's in the bench quite a bit for testing a few years back before we started doing the 2000's. This really depends a bit on your injector drivers and how much control you have over them. They'll start needing a lot of current for higher pressures (70+), but linearity will start to go eventually. Haha, as if they weren't non-linear enough already! Atomization actually gets pretty decent at higher pressures, but the cone of fuel gets a bit wider from the already very wide spray angle. This means even more fuel on the runner walls, which kinda negates the whole point..

So in the end I guess it really comes down to a whole lot of experimentation!

 

I run SX-15402 with my a1000 pump
