hey this may seem real dumb but i was thinkin .. if u were to make sumthing similar to this ...

but with litleholes like real small with little injector nosels and bolt it on the end of some kind of plenum ? i solrta made a pik in paint its real didgey but i tried LOL

the maroon parts are the inlets for the furel air mixture to go to the head... the yellow is the mixing chamber and the green is the fuel thing with th little injectors.. i was thinkin.. i reckon it would only work with a turbo
o would it work if u had say.. 5 psi boost.. and ur fuel pump was running say 10 psi? with a malpassi rising rate regulator? do u guys get what i mean ?

The holes look abit big. The finer the fuel "mist" the better the combustion.

Sure it might work, but making jetting adjustments to the device would be really hard. Also, Injectors are best placed pointing directly at the intake valves. If you look at most factory setups, this will confirm what I am saying.

I'm not sure what you are trying to say based on your pressures and all. Injectors are much better at pulsing the required fuel into the engine, this thing wouldn't be responsive enough. It's like the difference between using a spray gun or an open ended garden hose for painting your car.

It's good to see that you are interested in these things. I used to live near an industrial airconditioning factory, and I used to get cool guages and stuff (they were probably completely inaccurate, as I would find them in the big bin out the back..

Well if your going to run that, why not convert to LPG, it has a higher octane rating than pump gas.

It could work. You would need some way of controlling airflow, like a butterfly valve. But the nice thing about fuel injectors is they spray a nice fine mist of fuel, so it mixes well. In other words, you wouldn't need little holes in a circle like this to mix air and fuel together.

What is that part? A propane thingy?

lol haha nah im not guna run it i was just thinkin of ways u could run a blow through turbo setup with out going full injection.. and i aint boxin no carb in.. ( no offence 1200rc) but boxing carbs looks sad.. .. and u cant intercool a suk through.. and injection is just tooo much.. its hard for me to explain dattodude.. i used that thing as an example.. i was thinkin like geting say four little nosels made just real fine 1's and running fuel through them and have 1 of them hiclone things punt in behind it to get the air spinin and mix the fuel air mix up real good?

Woody, you might like mechanical fuel injection, like a Hilborn setup -- no computers, no electronics, simple setup.

dd tell me more?

ddgonzal... tell me more.. please .... i had a look n i like the idea of dimlights plenum thingy.. i reckon it would work well with a turbo set up.. just as long as u have 1 way valves, good fuel pump that shuildnt fail n a malpasi... oh and u would most probly need a hiclone ( a little thing that goes in front or behind were ur fuel comes out and makes the air fuel spin n mix in real well )
people feal free to coment.. i would like to have a gfo at this.. im getting a SERIES 3 BLUE BIRD next week and i might have a play with the ca20 ne way cyas

They should have mechanical FI stuff.

This thing looks like a very basic throttle body injection system. For the purpose of the exercise, i will overlook the fact that it is not throttleable.

Bendix electronic TBI systems were a factory option on Dodge, DeSoto & Chrysler cars in 1958, decades ahead of the industry, but the design shown here seems to spray fuel into a large plenum chamber.

In the event of a backfire, this plenum amounts to a small bomb under the hood, but the best way to make a small bomb perform like a big one, is to compress the ecplosive. 5 psi is not a lot, but it will increase the performance.
This is why is why modern engineers use the multipoint injection design with the injector located adjacent to the inlet port.

Woody, you are not the first, & won't be the last, but i think that you are trying to re-invent the wheel here.

There are a number of very good books on the subject of injection, & also on turbocharging that have names for the various parts, so you won't need to keep calling the diferent pieces "thingy" You need to know how to read to get the best from them though.
