well with gravity or without has very little significance because the change in elevation from top mount to bottom mount is only a few inches. the fuel pressure is constant anyways and will feed the injector no matter what.

on another note. the ITB setup i have is meant to have the injectors on top but in the late 90's the series swithes to a different chassis, rolt i believe, and the chassis space frame was in the way of the fuel rail so a new set of ITB's was created.

hes what im talking about:


and this


i will soon have pics of the model in Pro-E(3D modeling software i use)

 

they use sidefeed injectors? hmm.

 

no they have top feed injectors but the whole injector fits into the housing so it is not effected by vibration.

considering atlantic cars had almost no suspension, lol, i guess it was a good thing.

 

Im wondering how the plenium will look given the room to work with

 

oh you will like it. i have one of Bobby Rahal's old Indy 500 motors at my shop. huge turbo'd ****. the plenum on that thing is a very nice design and very compact too. i will try to replicate it.

stay tuned for pix. the plenum is part of the reason i wanted to place the injectors on the bottom.

 

Wow, cant wait to see the results!

 

I was kinda wondering, is it me, or how's he gonna make 4 work on 6 ?

If the Head is set up for it, I don't see how it can't make more power.

 

i have the two black ones in the pics in previous post and one more silver assembly. each assembly is for 2 cylinders.

the two black ones are from a 4age 4 cyl motor. the silver one is getting shipped to me as we speak from Jack Crone Racing in California.

if each assembly is for 2 cylinders, and i have 3 assemblies, then simple 2nd grade math yields a total of 6 cylinders worth of ITB's.

hey guess what i have a 6 cylinder engine...i think it will work
