Can a hilborn injection system be made streetable on a 283 sbc? And when I say streetable I'm thinking taking a 2000 mile trip or driving every day around town.. I love the way they look
they can be turned into EFI and are very streetable! I think a company in Canada sells the whole conversion for them but not sure of the name. I am sure people on the HAMB will know them.
My Hilborn is converted to EFI, with Accel Gen7 as the controller. I want an extremely driveable car, but I have to p*** emissions too, which I have no worries IMO....
Although possible, unless you're a good machinist with an intimate working knowledge of the mechanical compe***ion stuff, who's willing to fabricate vacuum lines and chambers, idle circuits and/or pumps or maybe even modify a p***enger pump off a Mercedes (good luck finding a suitable doner for a V8, especially one reasonably priced), it's not terribly practical for a many mile everyday street beater to do the mechanical stuff. Like stated above, one modified for EFI would give great divability, reasonable fuel economy, good power output, and is almost affordable if you buy one already done. If you're on a shoestring and want to do it yourself, there's a lot of information out there to help you out and several manufacturers that supply complete electronics. I believe it's Hilborn that sells a manifold with EFI injector bungs cast in for the electronic injectors themselves. You can make up the vacuum chamber and lines to the individual ports yourself, make up individual fuel lines or adaptor fuel rails for each bank. All and all, a VERY do-able and practical deal and if you're a little inventive can be made to look almost indistingishable from the mechanical ones. If you're not up to doing it yourself, I seem to vaguely remember an outfit in AZ that sells them complete, probably lots of others out there too.
Hot rod Magazine ran an article years ago on how to make a mechanical fuel injection work on the street. It would not be as good as EFI IMHO but it has been done. Sorry I do not remember what year or month the article was in. Will look when I get a chance and see if I can find it.
Mechanical fuel injection for the street can be done, but there's a reason you don't see it much if at all.The maintance factor its something you'll have to mess with all the time.
That truely does look sweet. I was envisioning the multilength stacks sticking out the hood, and was concerned about how you keep dirt out of your engine on a daily basis. How do you filter the air for daily use?
the biggest problem in making a mechanical injection system streetable is the barrel valve. they are designed to have full fuel flow at about 1/4 throttle. the next biggest problem is the constant(daily) tuning you need to do to get the engine to run properly at the current weather conditions. after that you biggest problem is that your fuel economy essentially goes in the sewer system. it can be done, but are you willing to make the sacrifice in the time required to educate yourself, and to constantly tune the system? at one time i actually considered this, and i still have the articles and books i bought(cant find them right now as they are ****tered under piles of books and magazines). but i realized that the effort to have mechanical fuel injection on the street wasnt worth the effort to me, unless i can find a rebuildable system from a six cylinder mercedes............................ efi is the better way to go
You can get an EFI system direct from Hilborn. It will still need some tweaking, but it is the way I chose to go. Doc.
Thanks guys! For mine I figured I would have to run a filter for daily use, though for short jaunts to shows I have stainless steel screens at the base of the stacks... For longer drives I simply made a stock 426 Hemi 8 barrel intake....
I know the mechanical syastems can be done for street on a blown motor... I can think of 3 or 4 guys without EFI on their injected street g***ers. But there are tricks to be sure. And, these are supercharged engines, not naturally aspirated (though I can think of guy with a natural aspirated mechanically injected street hemi as well). Even though the bugs are worked out on these guys' systems that I have run across, bear in mind that these engines are gas guzzlers what with the constant-flow injection.
