autonomics injectors
 

Alright I was looking for some help on finding the right size injectors from you 12a turbo experts out there
IVe got a stock s4 and manifold (using stock boost control)What is the boost limit on the s4 anyways???
anyways Ive got a rebuilt 12a streetport with the autonomics<<
throttle body and i was wondering which size would work good with that fuel rail
IVe looked into the injector sizing calculators and they all ask for hosepower but i honestly dont know what this car will have

I believe the boost limit is 14 or 15psi. I have an S5 turbo and am hoping to squeeze 15psi out of it. Other than that I can't help you sorry

try 650's on them you can get those from gslse or from na fc. if they dont work you might have to go smaller.

What are you using for fuel control and how many injectors are you using? You injector choice will depend on the # of injectors you are using, the fuel rail itself and whether you need low or high impedence ones.

Please post pics of this Autonomics set up.

on this autonomics setup there are 4 injectors on a holley style intake manifold.
Injector impedence dosnt matter because I am using megasquirt
I was wanting to use the injectors avalible off of autonomics because they offer the 4 injectors (remanufactured) and the fuel rail for 200 bucks. THe sizes availible are
Lucas 18Lb
Ford 24lb
ford 30 lb
ford 42lb
airsenseors 52lb which are the remanufactured injectors

This throttle body was designed for domestic parts from what I can put together

does anyone have a good idea for that sizing?

Since you are going Megasquirt, shoot for injectors that will support 300-350 hp. The stock turbo will not get you there, but that should give you enough fuel to stage your injectors for starting and for when boost comes on.

Stock S4 injectors are 4x550cc. First injector upgrade for the TII guys is a pair of 720's.

Keep us posted on this setup. I almost went this route instead of the TII I am prepping now.
