Ive searched through pages and pages of people asking about how to make a hillborn set up run on the street.I cant find any info other then that.can someone point me in the right direction.Any links?I would like to learn how this system works.Does anyone have an exploded view of parts involved in making this system work?i know its a kinda vague question,but try to help me out.Are there any decent books on the mechanical fuel injection?Thanks, pat Edit:i dont want to run on the street.I just wanted to know general info on how the system works.
I have one of these and some other parts for sale if interested http://www.kinsler.com/Cat_32_Pgs/Cat_32_4_09_Pg_115.pdf Check out the kinsler website also. They have fuel delivery drawing in PDF files. Mike at Alkydigger is very helpful and so are the folks at kinsler
Not trying to talk you out of it cuz it's cool as hell but mechanical injection is built more as an on/off switch rather than an adjustable throttle. But I'm sure you realize that going in. Obviously running mechanical fuel injection on the street demands more than a little bit of your attention while driving. In the example I have attached, the driver is manually manipulating the air/fuel ratio while driving by using the fuel shut off in the same way we would use a manual choke. In other examples I've seen folks using the Kinsler Jet Selector valve and adjusting on the fly. It can be done, just may not be as user friendly as you may want. Here is a feature from Hot Rod a little while back that do***ents how one guy did it and how he made it work. Just an example of one way to do it. I'm sure there have been other successful set ups http://www.hotrod.com/techarticles/hrdp_1201_mechanical_fuel_injection_breakin_the_rules/
I've got a friend with a 33 Willys street car that has made it work for years. It's currently in a two page spread od Street Rodder magazine. The car runs a really big inch Chevy and he drives it everywhere.
With the price of Megasquirt being so reasonable (let alone the fuel savings, driveability, al***ude adjustments, etc.), I don't know why anyone would want to drive Mechanical Injection on the street anymore-
Isn't there a Cheap$$$ ACCEL stand alone Electronic Fuel Injection control box that can be used in conjuction with elec injectors to convert to electronic,??? That would be street friendly & better mpg
Some of the uneducated want to do it because it sounds cool, some of them try it and get it figured out others do not. If you are a tuner by nature and like to tinker it can be fun. Some of the other uneducated want to run EFI because they have no understanding of tradition. They are the same guys that suggest that a TPI is better then a carb because carbs are not reliable enough to drive everyday. Patric, If you are serious what you really want is one of the Pete Jackson units that move the ****erflies away from the heads. They are nearly unobtanium. You also want to run a Pete Jackson stepped byp***, it will not give you an idle circuit but it will give you a mid range and a high range so they you are not running all the way on or all the way off all the time.
Patric, This has been hashed to death here, but the main thing mechanical injection does NOT do is respond to vacuum signal. You can add a vacuum referenced byp*** valve to the basic Hilborn setup and make it a LOT more streetable.
I don't find the driving experience / feel that much diffent than a dual carb set up. It's the MPG that limits my driving.
when this subject comes up i ask this question in hopes someone who knows more about EFI will respond, i really like the look of a hilborn setup but understand they are not ment to be used on the street, i'm sure it can be driven but not like an every day driver, the look of the EFI injectors is just not right so does anyone think you could replace the barrel valve with one large injector, large enough to supply the engine on it's own, remotely located and plumed into the distrubtion block, all run from a mega squirt or some other kind of computer.
We've built a couple of Injected cars we ran on the Street. Although they're short distance cars for the most part. This is what we're building right now. We're in the middle of this Crower Injected '51 Henry- J. Anyway what we've done is, and this is the short list. We used a belt type remote Hilborn Pump Drive, Hilborn 150-1 Pump, Kinsler Dial-A-Jet (Holds 8 Pills) Now find the pill size it seems to run OK on, and then you can go either side of it depemding on mostly the weather. Richer (smaller hole) or Leaner (bigger hole) We're sure you already know this. We made a surge tank out of an old Moon Tank with a Center Pivot Holley Float Bowl with (Hi Flow Needle & Seat) Adapted it on the back side of the tank placed as high as possible. Now in this way you can run a Fuel Cell in the trunk, and pump fuel forward to what is now a Surge Tank (Moon Tank) When it fills up the Holley float bowl shuts it off just like on a carb. Now that two gal+/- of gas becomes a reserver for the Hilborn Pump that's feed by the AN #12 line out the bottom. Also these tanks have two buns on the top for two #6 return lines. One from the Hilborn pump main byp*** and one Hi speed off the barrel valve if you run one. We don't run a High Speed for street, but the second return line can also serve as the bleed off line from the three (3) Way Main Shut Off. Last photo will give you a rough idea on plumbing. NOTE The second photo. See the pill holder that would normally be the MAIN Byp*** & Jet (Pill) holder off the pump. In this case it only serves as the poppet & spring for idle tension on the poppet. Take an old pill and drill it out WAY BIG like 5/16" and use it just as a spacer for the poppet valve spring to sit on. No main byp*** (pill) needed when you're running the Dial-A-Jet it's now your main byp*** with eight pills.There are several other tricks as well, but not enough room on this page. Our hats are off to Alkigigger Mike for his help and misc Imjection parts on this build. Also if you can grasp this idea. A friend of mine V Groved the barrel valve Spool from the flat so it comes off idle more gently. Make sure you V Grove the flat on the right side! LOL MAGOOZ Anyone can run an EFI, but it's not a true Old School Mech. Fuel Injection. Just make sure you have a high stall if an Automatic like 4000+ Call Alkidigger Mike 1- 615-483-6830 for parts he's a GREAT GUY!
A stack injection can be electrified, it gots done all the time. Some setups are still a little problematic as with the ****erflys that close to the head when things warm up the blades have a tendency to get a little loose in the barrels. I think that some of the newer computers are able to compensate for that. With some engines it is easier to hide the fuel rails than with others.
Yes i agree this has been beat to death,but i do not wish to run the hillborn set up on the street at all.Just for racing.I was just wanting to know general information about how the system works.
Alkydigger was brought up earlier. Here's a link to his mechanical injection TECH page: http://www.alkydigger.net/technicalinfo.php If you still have basic questions after reading through Mike's info, FIRE AWAY!
Go to HRE.com and buy Jim's fuel injection book. It's pretty informative and worth the small cost Al in TN
Right on.Yeah i haven't read all of that yet.I'm starting to get a better idea.It will be easier i think when i have all the parts in front of me.
I'll have to get that book when i scrounge some more cash..I'm barley going to have enough for the setup.
Had a fella here in mid Mi. that ran a 4 port on a 671 ***isted 464 big Buick. Maybe he was lucky, maybe he knew what he was doing, but that thing ran wonderful on the street. Only thing was that in the morning he had to give it a manual drink to get it going. After that it would start right up and run fine. This was about 15 years ago, and now the car ( chop/ channel '32) turns up right down the road from me. Car still runs strong, but not as streetable as it used to be. I'm ***uming that the new owner is not as knowledgable as the original. This guy was supposed to build me a blown 350 with a 4 port for a mud racer, but his business kinda went south and I was lucky to get my stuff back. Turned the build over to Reichert in Owosso. Everything in the build went fine but to this day I can't get the thing to run right. I tried carbs on it and that didn't work well either. Now I'm thinking that it might be in the MSD arrangement. Either way I don't think I'm gonna put the injection back on. I called Hillborn to inquire about the electronic conversion, and they scared me with the price. Might not be a lot for some people but....... In the first place I'm in way over my head with $13,000 in a small block that has been setting on the stand for 12 years. Oh the wonders of our hobby.................
Go Electronic....but try to hide it as much as possible. I use Megasquirt MS-1 $150 + Some soldering time... They www.diyautotune.com or www.glensgarage.com also sell them pre-built allready. + sensors and stuff you might need. The MS-1 only does the injectors / batch fired i.e. half the injectors fire at the same time. MS-2 also does spark and some hybrid sequential injection... MS-3 on top of that does true sequential and boost control, transmission control etc. MEGASQUIRT IS MUCH CHEAPER THAN MOST OTHER SYSTEMS! There's a forum where you can get help with testing, setup and tuning. www.megasquirt.info www.megamanual.com www.m***tra.com www.msefi.com www.ms3efi.com Megasquirt was developed by street/hot rodders that thought everyone should be able to afford EFI. Here's my Hilborn setup. http://www.jalopyjournal.com/forum/album.php?albumid=30451 I'm also building a MS-3 for my Potvin setup. Mechanical is for Hard Core Gas Guys...They Don't mind people crying behind them...IT IS COOL THOUGH! EFI is almost as cool, much smoother, SAVES GAS...AND it'll make ur ride go FASTER! just noticed, gotta run out and inspect some grenades! Tommy
alcohol anyone? no but seriously, I don't know much about these set-ups but ill be reading all this, in hope that I will get to run this one soon. hopefully on the street, we'll see..
Subscribed Man I've been needing some info on this topic myself. Thanks for all the info that's been posted so far.
