Title: Hilborn mechanical fuel injection Post by: Kiwi on September 16, 2009, 20:43:56 pm Couple of questions, Hilborn mechanical fuel injection with the tall stacks. Now the look is nice, but I understand that they are not useable on street use as they have little or no driveabilty on part throttle.
Can a electronic system be used to run it? Title: Re: Hilborn mechanical fuel injection Post by: Zach Gomulka on September 17, 2009, 02:43:20 am That would be cool. I don't see why you couldn't, but I'm no fuel injecton expert by a longshot ;)
Title: Re: Hilborn mechanical fuel injection Post by: Neil Davies on September 17, 2009, 10:45:12 am I'm fairly sure that there is a Hilborn style EFI system for V8s. I seem to rememer reading about it in Street Rodder or something like that.

Title: Re: Hilborn mechanical fuel injection Post by: rick m on September 18, 2009, 16:43:33 pm The answer is yes...you can convert the old HILBORNE to run on the street. I have a lot of V8 buddies who have done it. As one stated, it takes a little more dialing in as you won't have a mass air flow sensor but you can use other controls to fatten up or lean out the fuel curve with a programmable unit controlling the injectors.

Rick M It is Hilborn not Hilborne. Title: Re: Hilborn mechanical fuel injection Post by: Mike Lawless on September 21, 2009, 04:42:21 am I've been running it for a couple years now on methanol. There are certain valves you can employ to clean up the midrange and idle, but be prepared to use a lot of fuel.
