Looking to bump the volume off my pump.
guys running strokers and 24lbs injector, any changes to the pump?/ Pressure?
Almost gdne my summer honey do list and I want my blower on.

300 hp total I need 190lph~ pump? anyone try a v8 pump? I do have a renix non HO.
Or skip it and try a walbro 190/230 kinda pump, and convert the pickup un the tank?
I was going to use something like a vortec FMU to have varible pressur eon the rail..
Ideas?

I've got 30# injectors in my stroker without any pump issues... Do you happen to know what the stock pump is good for, volume & pressure?

Hesco told me that the stock pump is good for 275 HP. I've never had a problem in 3 years with 26.5 lb injectors.
Walbro does make a 250 ltr replacement for the in-tank pump; and Holley makes a 250 ltr in-line pump.
 
That's great to know.. Was told it was a 110lph pump.. Toi get to 275 I think it;s about the 150lph ranger. i think 275 is very do-able with 6psi.
Maybe I just need the rising rate regulator.
 
The factory pump has been working fine for my stroker running FMS #24 injectors. In addition to the injectors I have an Apexi SAFC to adjust the fuel curve and havent had any issues with it yet.

What are you using to add the suplemental fuel when boost kicks in?

AARON
 
Looking to add a vortec FMU. Still not certian on the ratio yet. x1 x2 x4. Will use boost pressure to change the pressure.
Not sue if I need to changre my MAP senor to accept positive boost yet.
How do you like the Apexi?
How much Hp does the stroker put out?
 
Am running Accel 24lbs Fuel Injectors, Hesco adjustable FPR, and stock pump. If memory serves me, the FPR is set at 31lbs at idle. (Vacuum increases pressure under acceleration).

I'm using the stock pump, stock regulator, 24lb injectors, and MAP adjuster set at 5.15v. Engine runs perfectly (knock on wood) and delivers excellent gas mileage.
