Mi16 Injectors

As I'm in the process of fitting my Jenvey bodies to my Mi16 it got me thinking about the injector requirements.

 

I'm hoping for around 190/200 bhp.

piper exhaust cam

4-2-1 manifold 2 1/4" exhaust

45mm bodies

 

Will the standard mi yellow injectors be capable of providing enough fuel for this. I have had a search through previous posts but I'm still not sure what the outcome is !!

 

If not what would be the preferred choice, I'm going to be running a 4 injector set up

I would have personally said that you're asking a bit much of the injectors at that power level and standard fuel pressure, and would have little if any margin for safety left in the duty cycle at full load. From what I've gathered and worked out, in the region of 180-185hp seems to be the safe limit for Mi injectors on an average NA engine.

 

Something like GTi-6 injectors would probably be a better bet, as they're easily and cheaply available, the same fitment and flow about 20-25% more than 1.9/Mi16 injectors with an improved spray pattern too. From memory, Mi16 injectors are around 214cc and GTi-6 injectors are more like 260cc

Excellent thanks Anthony,

 

I did come across a few saying Gti 6 injectors then I started reading about saab injectors etc. Basically didn't know what to believe.

 

Regarding fuel pressure, I was going to just leave than as standard or would I be better with some means of adjustment on this ?

 

I'm just using the standard fuel pump if that makes any odds ?

Standard fuel pressure and GTI-6 injectors will be more than adequate for 200.

Don't mean to spam but I've got a set for sale that came off Sartys bodies. They were cleaned last year and with this setup it made 240bhp iirc.

Gti6 injectors it is then.

 

What is the standard pressure ? I was thinking 3 bar ??

 

How much are you wanting for the injectors mate ?
