i do have 2 of them. but never seemed to need the 2nd one. right now I'm seeing mid 10afr on 18psi.
they are seeing about 14.5 volts. -8 feed. -6 return

i just don't see how the car would be making 500whp right now.lol

I didn't know those claimed 90gph at 73psi that's darn good for the money. I just bought one to put on the new project.

i just dont see how it would be making anything less than 600whp right now at that boost level. and it feels pretty damn fast as it is.
i see about 10psi in first gear than 2nd and 3rd gear right around 18ish.

17* degrees up top.

One would definitely think that it's making some steam on 18 psi. You sure that 2nd pump isn't coming on? Lol.

i have it on a switch to turn on manually, so yes. lol.

fuel pressure never dropped on 8psi or 14psi. it wasnt till i turned it up to 18psi that i seen it drop FP in 3rd gear under WOT. went from almost 80psi to 55psi.

Heres a comparison to the walbro 450, which plenty of people are making well over 700whp on e85 withit. The AEM flows alot more after 80psi compared to the 450.

This explains why i can make 18psi on this on3 88mm turbo on E85 and 80lb injectors on a single AEM 380 pump. These pumps are beast.
Ill be cranking it up to 23psi and hitting the dyno in a week or so.

Figured this is good info on this aem pump since i couldnt find much on it

What's duty cycle on those 80# injectors? It was suggested by more than one person that 30-40% more injector is needed when going E85 as to not max out

Did you have a trans brake or no?
What will the converter stall to on motor? 2300 seems super low?
Using the anti lag or the 2-step? Screen shot of settings maybe?

Just trying to get an idea of what that turbo will take to come up on a 5.3.

Looks fun!

I was just testing it for fun. Havent messed with it
No transbrake just the antilag from MS.

2300rpm builds 1psi.

Converter stalls up to 2800-3000rpm on the foot brake so i gota bump up the antilag rpm next time i try it.

My boost guage must be off by 2psi or so.
Log is showing 16psi max.
