Nice progress - the angle of your fuel injectors looks very steep?

The angle is 45 degrees. No space to have more..
Take a look on this page, I did some reading about this angle problem before I made the inlet.

I had to chuckle at the irony of a hotrod magazine talking about EFI... still times change.

I think you'l struggle with cold start personally, could you not mount them on the underside? A change of injector type might also be beneficial, assuming these are single pintle EV-1?

Fuel pressure and spray pattern are critical if you're going to avoid fuel droplet formation, and the poor AFR/idle quality associated with it.

Nice project though  8)

I dont know  :) This is the first car I'm building, so I guess time will show if it works or not :D
Ev14 with 4 or 5 holes.. QSP fuel pump, think it will have 3 bar of fuel pressure, using an-6 hoses..
