Should've.Didn't.It would definitely look great,but how do they go? Are they remotely streetable?

I have seen sevaral on Holden sixes. All at the drags though.
From what i gather, unlike a carbie which has three stages (idle, middle and top end) mechanical fuel injection only has two stages (idle and top end)
Now, this is not from personal experience, just what i have picked up looking at the topic, i believe that yes you would be able to drive it on the street, but the fuel economy would be absolutely shithouse just cruising around town. Also you will probably foul plugs continuously. Mostly ment for WOT applications.
That said, is there any way you could graft two or three pill boxes in a series to give you different fuel levels at different rpm???
Cheers.

I have no real experience with that setup yet believe with much stuffing around it could be made to work.
A lot of the light aircraft use Lycoming engines and mechanical injection is common on some of those engines.
Anyone who has flown light aircraft are probably faimilar with the mixture lever beside throttle and the leaning/richening that goes on while watching exhaust gas temp and the mechanical injection guys have to do this just like the carby guys.
Mechanical injection is a pain convert it to electronic and have hassle free motoring.

I've got that same setup as in your pic, only mine is a one piece manifold, never used it though and couldnt find much info on it, or anywhere to get parts for it??

a few cars used mechanical injection. porsche did, as did 50's corvettes i think

Squillions of cars used mechanical injection, eg. during the seventies the Bosch K type continuous injection system was popular and worked well. Some cars (eg Alfas) had diesel-style timed pumps that also worked very well. It's possible to get systems like the one in your photo working on a street car but it's difficult to get right and keep right. The main problem is that because you'd be running petrol instead of methanol and because it's a small engine the flow rates (especially at idle and light throttle) would be tiny, and even with small nozzles flow consistency might be a problem and possibly even distribution. Full throttle should be OK tho. To be honest nearly any of the other injection systems would be much better on the street - EFI, Bosch K or timed mechanical. If you really want the open trumpet look you'd be better off with a MAFless efi setup.

Hi, I also have a mechanical McGee setup and was trying to find/get help on setting up to run it on the street. I got some good info and it was all bad. Too much fuel at idle right through progressive band and it would be nothing but trouble. Iam now trying to find somebody that can convert from mechanical to EFI on the old McGee. I still want to run this system as it is going onto an Irving alloy head.
Cheers Steve

i was told to convert mine to efi, but im not that fussed about running it on the street( i bought a set of triple webers instead) i just want to set it up on a motor i have here. i found a little bit of info on similar set ups on www.kinsler.com

Hi Wot 179,
i have seen a few people use those type of injection on their cars at the strip but doubt you could use it sucessfully on strip i did see in the latest smachine mag there is like a old gasser with it on but running methanol on the street is like the roulet wheel at the casinos if the cops catch you using it.i have added a few pics of dads fed he first used new hilbourne mech injection and he now has this new engine with supercharger that uses a 2 throat hilbourne injection setup i have been involved in tuning both these engines and from what i can seen they have nothing to meter fuel inrelation to the butterflys and the amount of load on engine just idle and flat the barel valve just has a small slot that widens out as throttle opens but hey they do work very well well the new stuff dad has does, not so sure about the older type stuff but would think it would simalar. were you going to use it with alcohol or pump fuel?,
Thanks Hayden

You can change the metering by running different scrolls in the barrel valve. Don't forget you can also have high speed leanouts as well. I had a big block chev once that come with a hilborn setup with jetting for petrol and methanol. Used Methanol cause it had to higher comp for Avgas and C16 was 2 dear. Best bet is talk to someone like Ken lowe or someone that flows mechanical systems. There is a Lx hatch in brissie that runs mechanical setup on pump fuel and has worked out well.Hi Wot 179,

Hi
My company SONIC injection can modify your McGee manifold for EFI. We did it with our own McGee before deciding to a NEW Injection manifold with heaps of improvements. They are CNC machined for either mechanical or EFI. I can supply them with Trumpets or air cleaners. I also offer difference throttle blade angles for street or full race applications. I'm assembling the prototype this week if anyone is interested in photo's of it
