Scott Fuel Injection

[FrankBoss]

Talking to a buddy today he told me about a mechanical fuel injection he bought in the late 50's wich worked over a strongberg carb base.
The name I reconized but the format was nothing I heard of before.
he claimed it worked well and the cost back them was a little over 20 dollars.

So I did find a little on the web about the the injection on the web.
has anyone tried a mechanical injection on our sixxes.
salt flats or some drags???

Why would you when electronic fuel injection is so readily avaliable?

maybe he thinks like i do and hates to trust his car's life to a bunch of computer chips and wiring harnesses which fail at random. truth is, i have dreams of doing similar to my 300, but i havent researched it yet

Well I am a mechanical engineer and I trust electronics more than mechanical systems

But I mean, why trust your transportation to complicated things that use electricity and combustion which can fail at random. Just stick with a horse

Most old mechanical sytems for racing had idle and main circuits only, there were no intermediate circuits so drivability is horrible, if even possible.

Even systems like the Bosch K-Jet are prone to needing a good sorting-out.

An old FI setup would be cool on a period car. Otherwise - more trouble than merit.

I was thinking of race only system... I know englisser has a MFI for the 2.3 and 2.0L that the sand rails and a few off road trucks run.

everyone talks EFI and thats kewl I rather look at the odd a diffrent options.(you might as well asked me why I dont put a V8 in my car)
and EFI isnt for everyone, I have a mega sqirt and I havent even got passed the program parts just like the guy I bought it from. So if a road less ventured, why not look anyways. isnt that what this site is about?

anyways I love Vintage stuff and if I could afford a few older rides I would.
with early mechanical it was used in place of carbs and later put on top of blowers and has a legacy in the vintage drags. all those thing I dig. And who knows something old becomes something new again.

So I was wondering if anyone looked at this route or knew much about the old Scott injection. I have used Bosch MFI and it was a little more complex than a racing system. Maybe I should look at hilborn and how it works, the scott system seems a little different.

this is the only forum I really could think of asking such a question since the group is so inovated to devlop something different.

How did that stuff differ from the Rochester stuff in the 50's and 60's? Was there anything other than the rochester stuff offerd for street cars in the US back then? I know of those systems but never really looked into how they worked.

I know some of the pontiacs and vettes had it as an option. I hear its worth big bucks if you got a trailer queen but if you want to drive it you are better off with carb(s).

As long as Im asking..... was Cadillac the first with multiport electronic fuel injection in '75? I think it was known as the Bendix system. I know GM did TBI in 81 and cadillac had their 'digital' TBI then. From what I have seen most of the other FI systems till the 80's were bosh like mechanical systems.

8) mercedes benz had a mechanical fuel injection system in the 50's on their 300sl and slc sports cars. in fact that is one idea i was pondering, find the injection pump, as well as the rest of the system, from one and adapt it to one of my sixes.

 

[FrankBoss]

the Boch, Carter and Benz injection is more complex than these systems and yes these are really a full out race injection system.

if your working in a street machine they use one small carb and two FI units the carb was the primary and the FI was secondary to keep from loading up in traffic.

The period of time these came out was in the 50's and the options on cheap carberation was limited. the Strongberg was king due to they were everywhere, Cheap and easy to tune. Manifold wise it was very common for multi carbs rather than one big carb becouse there wasnt much choices in 4 barrel carbs(Not Like today) so the hot rodders slapped more carbs on to gain performance. Well Scott Fuel Injection was the next step kinda ahead of its time. the guy only manufactured these for about 6 years but his fuel injection won three years of NHRA event and was manufactured by M/T for a long time.

Now this might sound like its totaly out of date tech but its not any different than the tripple one barrels on a log intake.
I didnt know if anyone had any background working or racing with a Scotts Fuel Injection. Even the Modle called the Blade was itreeging to me becaus of the shape , it could be manufactured in a smaller scale and mounted to a Log intake..

a little food for thought.

There is a mechanical throttle body injection system still available that is primarily used in light aircraft. It is reliable (duh) and highly tunable for mixture. But it is not cheap. A single unit costs something around $3000 and that does not include pumps or plumbing.

Good call! There is a cheaper (yet still with a good reputation) system called the ellison:

The EFS 3A is the right size for a 200-250 and is about $850 new. I was getting ready to buy one for $600 (used) about 7 years ago when I stumbled upon the correct aircraft carb that I needed.

 

[FrankBoss]

Those are very very kewl... what about older aircraft injection would that be a option for speed...

I would like to know more bout racing injection as much as possible.. older injectors for super chagers and such... what about Boats? I know some of the vintage boats had machanial injection in their racing applications.

I'm not a engineer by any meens but I feel a nitch here that I might want to venture.

... what about Boats?

Injectors units don't know what kind of engine they are bolted on, They just look at throttle position, and the better ones also measure airflow.....and then meter fuel accordingly. Racing boats? Most likelysame eqp. as drag racing.
Pleasure boats? Most were carbed, but whatever injection systems you find will usually be auto-based.

"Older aircraft" = needs replacement parts to make work = either expensive or very hard to get.

 

[FrankBoss]

I guess what I'm really into on this is the Drag racing aspect...I live really close to a track....

yes Drag boats ... older wooden boats from the early 60's...

I havent found anything on the web about Vintage drag injection other than sales...no blogs on repair or how they function....

[prostkxy]

there was a setup called a mcgee mechanical injection take alook at this
