Can I run a low pressure fuel pump??
Max psi on the pump is 20 psi, I am looking at running (6) 1680 cc injectors on a pp turbo set up? Th epump is a Mallory Comp 250 for Alcohol.
|
what flow at 20psi? how many lph?
|
250 gph - Free Flow
260 gph at 6 psi -8AN Inlet/Outlet |
That sounds like a carb pump for alky. I would be concerned with the spray pattern coming from the injectors going that low.
|
What pump should I be looking at??:scratch:
|
I just run a vane type pump that was made for a Ford truck, they run about 90psi if needed and will flow over 100 gals an hour. Its regulated down to the standard 40 psi +or- range for injection.
With out doing the math, are you sure you need 6 injectors that big??? |
I'm looking to run a gt45 comparable turbo, lt10,p port on methanol. Where can I find the ford pump at? Part number? I have not purchased the extra injectors, I have 2-850's and 2-1680's. I was going to put the extra 2 on the motor. My setup only has 4 bungs.

I'm only trying to feed about 250 hp. You might be better off with a Bosch 0 580 254 957. Rated at 90GPH@70PSI. I was a little off on my fuel flow of my pump, it does about 40GPH.
Real quick figuring, your 4 injectors will feed about 800hp on gas, I don't know how many more pounds per hr alky needs, IIRC its about twice as much from hanging around my dragrace buddies, so, maybe 400-500hp? The next concern would be the pump surviving the alky, IIRC they have some with a lubricant mixed in, that might be what you need. |
