SHO Nut FPR Setting with PowerDyne Setup

[BigCaney]

Well after a long time off the road installing a PowerDyne setup, my SHO Plus is almost ready to roll again.

I am running a Walbro HP255lph fuel pump and F4SE Blue top 36lbs fuel injectors. I am having trouble getting the motor to run. I am curious to know if my SHO Nut Fuel Pressure Regulator (basic kit) should be set at the stock setting of 39psi or at a different psi setting ???

Thanks for any help or suggestions.

Unless your running out of fuel as in injectors are hitting over 80% duty cycle just set it for 39psi relitive. The instructions are all on his site if you need them.

Pretty sparse info there Chief. What exactly is happening? What means are you using to tune it? Got spark? Got fuel? Anything else recently installed, or just the fuel system components and the SC?

I don't think you can run the basic fpr kit with a hp255 fuel pump.

Why ?

Yes you can, that's why Josh made this kit. It uses the same FPR as the higher version that Josh sells.

I am running it right now and it works.

If u just threw the injectors in it won't start. Anytime u change the injectors u need to tell the the computer. Unless u have a tune already. But like toolman said we need more info.

I have been working with the same injectors in my turbo car . Like others have said you need a tuner to change the injector values . A tweecer or quarterhorse will get you running again . If you need help finding values for the 36's pm me .

Running Now

Not exactly what was going on, but it seems to be running like a champ now.

I have a few more things to do before I can take the first road test, but it sounds great, starts great and takes the fuel great. I only hopes it does as well on the road as it does on the jack stands.

Thanks for all the input.
