Perfectly happy with my factory 997.1 intake, but considering going to dual injectors. I have seen several of ya'lls bad *** intake setups, but I am wondering what is the lowest cost way to run dual injectors? I am not looking for a better intake manifold.. just two bosses for injectors

 

if you are using 997tt intake I don't think you can do this because its plastic. so unless you make a spacer to sit under it for the second set of injectors, but that may just set the intake too high up. most people are using the twin injector stub manifolds from magnus. I have a second set of rails above the first set, set higher up.

 

Ya, Magnus + GT2 is probably the way to go. I really dont *need* it, but would like to get away from a single 2000cc injector.

 

I cant see how you would do it with a stock 997TT intake, I don't there is enough space for a spacer.

 

Yep, that was my assumption.

 

 

ESmotor built a great intake monifold that run 12 injectors .. you can PM them to check

 

The pics of my intake above is the Esmotor setup. It uses ISC/Magnus lower plenum for dual injector, GT3 RS 4.0 upper, and ES Motor billet center section. After mock ups for fitment I had everything coated in that ceramic/matte black by Driversource in Houston.

 

Looks inexpensive

 

its not so bad when you spread your costs out over 2 years like I have .

 

Just curious to learn if there is any benefit running the secondary injectors higher than the first set? Wouldn't it be easier to get the Magnus stubs?

Thanks!

 

 

Thanks for the input.

I know it's hard but Is there a rough estimate to when one would need to run a dual injectors set up?

I'm currently running ASNU 1500's, would like to know how much power should I expect before needing a dual set up.

Thanks!

 

 

I should probably add - while it’s possible to get those numbers out of a single set I wouldn’t call it a good idea. If anything goes wrong with the fuel system to lower the maximum available output you could find yourself with a seriously expensive situation.

I would suggest building at least 20% headroom into it if not more. Fuel system tends to be the thing people always overlook. While not as sexy as some other parts, the engine only uses air and fuel. Why we spend so much trying to get air into the engine but try to run the fuel system at 110% is one of those mysteries of life.
