This is a g2 vs a g3 on the same pulley 105mm and same fuel. Same everything except the unit itself. Yes it's a bit more than 7psi but if you look over both curves everywhere it is making more power so that would also be the same for a larger pulley. Ess has said the psi difference is negligible...

If you run the same pulley on a G2 vs G3 no matter what pullley it is the G3 is going to make more power everywhere in the curve. Down low it would not be perceivable but up top could be as much as 30-40hp more.

You can send it in for a rebuild though if I recall it's like 500 bucks or something

Did you have a steel flywheel

Its not that I didn't think it wasn't doing anything. I wasn't aware they are constant voltage like I was saying in my post I thought the bap only over volts paste 50% throttle. Since I had the bap on with a different fuel pump, the w525 and it was reading 65 psi at idle then when I put the...

Then why would it not be the same with the walbro vs the dw400 The 525 showed 65 psi with the bap

Purchased a used vortech boost a pump about a year ago. Used it with the oem fuel pump and a walbro 525. At idle the low side pressure would be around 65 which is what the ecu commanded. Then I switched to a dw400 and my low side pressure went to 80psi constantly unless I'm giving it a lot of...

Do you know what pulley you're going to use for that? I hit 880 on the 100mm but on e50 so I was thinking maybe a 90 on e85 would be around 1000

I think that would be pretty short. I have the 3.73 and really like that. I agree a centri should be easier on the clutch. I just put in a rxt. The stock one wasn't slipping though. Even still though the kit does get into power early. Around 3200 I'm making 500 ft lbs and by 4700 it's making 600.

Jealous lol jk idk. I hadn't heard anything about that. If they actually had questions you would think they would come in here and ask rather than bashing it in another thread.

Oh definitely. For a 15-17 there's nothing else needed. For the price these are an awesome buy. I'm a fan of their fuel rail crossover. These can even be used in a return style if you want. There are ports at the front and back and side of the rails.

Kevin and I have these https://www.boombaracing.com/mustang-gt-fuel-rail-natural/ The feed line is a different feed style because the crossover is in the middle of the rails. The crossover supply is 8an so its pretty big. Fuel comes to the driver side middle rail then the passenger side...

Could be? I'm not sure. It's gotten better that's for sure. I have about 500 miles on it. There is no slip anymore but still some chatter.

I see. I had thought you were talking about starving the high side since the new rail is setup differently but the sensor youte talking about is the low side sensor. I guess I could see how maybe there is less of a drop in pressure simply by how the rail is setup but I don't see how you couldn't...

That is confusing. So the lift pump pressure reading is on the rail taken from the driver side sensor and the pid "rail pressure" is the hpfp's own sensor

The pids I use are lift pump actual and lift pump desired

Can you explain more though? When I log I see rail pressure and lift pump pressure. Lift pump is the low side I'm assuming there is a sensor within the pump? An average at idle reading for that would be around 65 psi. But the rail pressure is in the thousands. If that sensor is reading the rail...

It would seem that hasn't negatively impacted the pressures though.

Fueling should be golden with that on pump gas.
