Have the following setup:

ID1000
Returnless AP2
Dw300 fuel pump
SOS Spercharger Novi 1200
Upgraded heat exchanger
Stock exhaust with decat
4bar mapsensor
NGK BKR8EIX
Competition Clutch Stage 3

Im hitting 100% duty on E85 at 7600rpm.
Max psi is 9 at about 8 000rpm

I think that this is wierd? Or is it normal?

I have a smaller pully home and now im thinking about installing this and go for 13psi on gas.

Please help me!

That's weird. Maybe your fuel pump isn't hardwire to your battery with a relay.

 

It is, but something have to be wrong....!
Can someone send me a picture of the hardwire-install?

 

My ID1000s hit 100% duty at around 7000 RPM and 15 psi on E85 as another data point.

 

Thx man!
I will check my relay and hard wire again, so i didnt f@#k it up.

It sounds like i should get away with 10psi and E85 on my setup

 

Run a bigger fuel pump (hardwire it) and bump the pressure.

 

Returnless AP2

There's your problem. Do you have a gauge on your fuel rail?

 

I don´t have a gauge on my fuel rail
Hmmm.. I think I will tune it on gas instead... Then I cant be low on fuel?


This is my hard wire. Cant be wrong?

Good catch... I never pay attention to the returnless part.

 

Well, you'll certainly have more headroom on regular gas, but ultimately you'll want to do a conversion to a return style fuel system. If you're set on the ID100s then you'd need to bump up your fuel pressure but you can't do that effectively on the stock returnless.
