ESS G3 Smallest Pulley size without fuel system

[SheepDog]

It’s so tiny!!! What was your PI fuel pressure reading there? That timing is very nice, I see a max of around 20 degrees with mine.

it's constantly targeting 2900, and bounces above and below

Im gonna pulley down to the 105, so I can move as much air as a 120 at sea level.

What fuel pressure are you seeing at idle?
Edit: as in what lift pump pressure at idle?

 

[SheepDog]

Down around 6200 RPM, Im seeing close to 25 degrees. Can't do that on pump gas, even with a 150MM pulley.

Right around 900-1000. My idle is 800 RPM though.

Lift pump is at 52-54 PSI. That is what Dr. Wengerd asked me to set the pressure regulator at, and it is indeed right there.

Sorry the actual lift pump pressure. In your pic it shows 61 psi but what is it at idle?

So you are seeing around 9 psi of boost since the FPR is 1:1. That’s not to bad considering your elevation!

Great observation. I was curious about this myself, as I have not yet installed a boost gauge.

Well thank you my friend! All it takes is to have fuel issues and you start paying attention to those things especially running 18 psi of boost. That’s why I have a AEM fuel pressure gauge in the dash so I can monitor it constantly. I will say since the new fuel hat was installed and the third pump is on a Hobbs switch we have seen a peak pressure of 76 psi vs 68 previously. You have seen me say it before and I’ll say it again proper fuel and tune and you can get a lot out of these motors!

Very true. 18PSI is kill mode.

Don't play that dumb 'is it safe on 93' game. As @Cory S said, keep it under 700.
Personally I think a return system is all hype.

We shall see what it will handle. The true test is how that fuel pressure is holding through a pull. The 76 is just a peak recall and I haven’t had the time to actually log it yet unfortunately the car hasn’t even left the driveway in a week… ok I actually drove it around my cul de sac this morning so I don’t get flat spots on the tires!

On gasoline. 100% truth. My buddy puts down 833 on a Mustang loaded Dyno with 93 and WMI with just a DW400 and BAP. Through 100% factory active exhaust.

I'm on a 122.5mm. Car pulls timing with my local 93 & Florida heat.

In cold weather, it will pull all the spark.
