What size nozzle?
 

Hi all,

What diameter nozzle should i use on a d.i.y. cold start system?

Thanks

O.K. then i'm gonna go for 1mm.

I would think upstream pressure and the desired nozzle "spray pattern" would need to be known ...for anyone else to offer an opinion on what nozzle size to use. Look at any one of the industrial supply places ( at least here in the States)...like McMaster-Carr, Graingers, for guidance..

Hey...is this a continuation of the 1970 engine-in-a-1973 car "cold start thread" ???

I think you should link this question to that thread..didn't know the history..sorry..

I used a cold start injector out of a 2.8 Chevy V6 on my d.i.y. efi.

Cheers,
