Injectors

[Weatheralls Auto]

This will be for a 3500 Turbo.
Thinking I should run 60# injectors.

1, What type to get multitech 1 or 2?
I have a rail here from an old 3400, it has the Fat injectors on it.(multitec 1s? )
Also have a rail from the 3500, has shorter and skinnier injectors (multitec 2s? )

I can't use the 3500 rail, but those injectors will fit the 3400 rail, and are shorter which will give more clearence?

So which ones should I use?
Where is the best place to source them out?

60lb/hr injectors? what kind of HP target are you looking at?

[Weatheralls Auto]

Not much boost, 6 to 14 max!

60 is just what has been recommended so they are not maxed out.

The more reading I am doing it seems I could go lower.

But when I asked this before, some said 42.5 would be the lowest?

[robertisaar]

maybe at 14psi, would they be necessary...

when you start playing with injectors that large, it'e because you're spinning the motor a lot faster than normal, have great VE at high RPM or LOTS of boost or any combination of the three...

i believe you can calc a fairly accurate number from RPM at peak torque, BSFC, and peak TQ numbers...

L67 injectors (36lb iirc) or the Lucas 42.5# injectors will be plenty, 60# injectors are huge and will take alot more to tune down.. Im running 42.5# inj on mine.

I think I have some l67 injectors available to me,
So with DD I see about 340Hp and 345Tq
Will have an adjustable FPR and High flow pump.
So these 36lbs should be more than enough according to http://www.witchhunter.com/injectorcalc1.php4
