Enderle-hilborn Help Needed

[BLOWNDEAVER]

HELLO, I am currently trying to make a decision on fuel system: kasse hydro-540 bbc,11-1 comp, littlefield 10-71 (30 percent over),birdcather ,58 nozzles,running methenol,hilborn 175 series pump,and it is a 4, is this pump to BIG, or can it work with hi-speed? please help!!!!!!! :cry: :argue:

It can work with what is called....a pump taylor. This is nothing more than an additional bypass that bypasses fuel back to the tank all the time....thus making the pump act smaller than it is. BUT...you should call one of the guys that flow systems and let them at least ballpark you with a starting fuel curve. Or let them flow the system.

I think that you will be ok with the Hilborn pump that you are using, from what I have found it should put out around 7.03 gpm at 1800 rpm with 50 psi.
I run a simular set up (498ci, 8-71@45%, enderle bird), the exception being that I run a enderle 110 pump that flows 13gpm, and my nozzels are staggered from front to rear (59,58,56,54). Like Fiat said having the system flowed is a good Idea that could save you big in the long run.

HELLO, the info i found shows hilborn flows 17.5 @8000 rpm and enderle 110 flows 13 @8000, i cannot compare pumps @ 1800 rpm, does someone know enderles flow # @ 1800 rpm, tell me if i am seeing this wrong,

From the Hilborn site:
The first digit of the serial number stamped (not cast) into HILBORN pump castings indicates the pump volume.
PG175 series
#2 - Large engines with high percentages of nitro and blown engines on methanol.
#4 - Very large engines, high percentages of nitro, and blown engines on nitro.
I think a PG175 -2 has about the same flow as a 110 Enderle pump. 13 gpm.
A -4 pump is probably like a 990 or 1100 pump in an Enderle.
Here are Enderle flow numbers. Can't find Hilborns.
80A-0 Pump 4.5 gpm
80A-0.5 Pump 5.5 gpm
80A-1 Pump 7 gpm
600 Pump 9 gpm
110 Pump 13 gpm
990 Pump 15 gpm
1100 Pump 17 gpm
1200 Pump 19 gpm
Like I said....Call Hilborn and tell them what you want to do. Save yourself a lot of grief.
