approx 12mpg and that is mostly joyrides, burnouts, stop and go traffic 35mph max between my house and the dyno lol

i would bet it gets 18 or even clears 22mpg with alll highway lockup driving nice etc

Same here with both of my Derale holders, junk.

from what i hear from people who wire for a living all these fuse holders will do that over 10amps

That is amazingly good! This (with a full exhaust) truly is a fantastic all-around setup for a fast daily driver.

Try using the car audio stuff from companies like Stinger.

You just use the factory fuel filters with built in regulator and not rising rate regulator? So at 17lbs your at 41psi fuel pressure? Or is your base higher?

Stock return truck rail 58 psi all the time no rising rate

Saw your comparison pics to the 88/83 that is helpful!

Think the S480 clone will make low-mid 900's at 25PSI?

denmah

yeah according to the math 930 range should be 25~

i think it can definitely get close

So 41 psi in to the manifold

I would think the stock regulator is manifold referenced, so it will be running 58 psi across the injectors no matter the manifold pressure.

Sorry if you posted it somewhere but when will VSRacing start selling these S480 clones? I'm thinking about using one on my LQ4 Fbody now after reading this.

Actually, I wonder if it'll even fit in an Fbody? Lol.

Stock regulators are not referenced.

I was just listening to a podcast with Scott Clark and he said they are working on a TAC module.

Some of them are

I would guess denmah just has the reference line removed. So no vacuum or boost applied means 58psi all the time as measured at the rail.

And roughly 41psi delta across the injector with 17psi boost in the manifold.

Where can that podcast be found? And what do the initials TAC actually mean? Lol

Anybody actually confirm this is a rising rate regulator (or at least a reducing rate unit) vs it being just a pulse damper of some sort?

Typically they drop lrrsdure when there's vacuum. That's the reason for the vacuum hose. I know some raise for sure because a dry nitrous system can pressurize the regulator to increase pressure.

From my experience it acts like a 1:1 rising rate regulator.

See the below screen shot of one of my logs. Fuel psi is roughly ~61psi at 2 psi boost. Then jumps up abruptly when my hobbs switch kicks the second fuel pump on but averages ~71.5psi at 10 psi boost(highlighted area). Same relationship has been recorded on 17psi logs.
