4- barrel VS IR injection

[Caprimaniac]

Well. For those who's interested I now have lots of pics and details on the Moon crossram manifold for the 302.

I can post it here if someone is interested.

Let's see how this setup looks like (I've omitted the carbon trumpets because of reasons mentioned above...):



The distance from the butterfly and injector to the valve head, the distance is 13".
The spray direction from the injectors have been added. Spry pattern has 15% sread to each side (not in drawing).

How will this work: cold start and idling? (At WOT, it will hopefully work very well, uhu?)

Rune,

I like your idea with the injector, but I would lay it over to aim at the centre of the runner rather than the floor.

Is that using the 30mm (thickness) Jenvey throttle bodies?

Hi.

Yeah, Gaz- that's the Jenvey 30mm's.

The injector angle is fixed on the bodies. The picture of the manifold has some distortion, and the angles are not 100% correct. I have tried to extrapolate to put the bodies on the manifold as they will be in the real world.

Therefore, I cannot alter the direction of spray. And that is one of the concerns....!

But let's have a look at another drawing. This is the Inglese IDF manifold with throttle bodies. This is even worse, yes?


I do have the possibility, though, to buy an IDF maniolfd and bolt on the reverse plates..... Is there someone who've tried this on the 302 and found enough room between the TB's for fuel rails????

Oh yeah, Lovehamma. That's really something.Looking good, i think. Some chrome details and a black hood with a scoop. A little "hot" but not too much of it.

That's a great Stang. Wouldn't be embarassed to show up in that one either... Actually I'm not a great fan of Mustangs but this one has it all. Looks, style, (on paper) a great suspension setup & a really great engine. To be honest, if it was me doing that Mustang, I wouldn't put that much into looks. Gunmetal flat grey & no plastic styling except a needed front air dam + rear huge wing, I guess is mine cup of tea in the Mustang department.

Yup, Gaz- been looking at the TWM systems. (Apparently they do not have crossram for 302?). As you can see, the injectors sits a bit closer to the heads on the TWM system and on the Hilborn for that matter, than on my drawing.

The only "true world example" I've seen on injector position experimentation on a (Ford?)V8 was some 1500- 2000 hp turbo engine (by, if I remember correct one of the guys that rune the EFI university). They found maximum horsepower by placing the injectors about 4" or so above the ports and not, as on most inlet manifolds, at the port openings in the heads.

I'm now thinking- after you posted the "reverse IDA plates": Why not fabricate some for the IDF's and run the manifold I already have? By any chance not much different from the Moon or Hillborn setup for yhat matter. Would save me plenty of cash as well.

Have to measure to see if there's room for the fuel rails and injectors turned towards centre of engine. I'm into the thinking booth.

Call me in a month or so....
