Want to run a/w injection to suprchrgd Porsche

CarreraSC · 06-21-2008

Hello,

I have a Porsche 993 with a TPC Eaton Supercharger without intercooler. I would like to lower intake temps to reduce heat soak during road track events. What is the best setup for this application?

I'm assuming you have this set up.

The Stage 2 kit with a DO4 to DO5, for up to 6 to 9psi applications, Not sure how much your running. I would add a 2 bar map sensor to the set up. I'm not familiar with what the ECU piggyback comes with. This would be the best set up if your wanting to go progressive. If you want to use a Stage 1 kit go with the low boost kit with the same size nozzles.

If you do have a 0 to 5 volt MAF sensor you can also use the voltage faced controller to reference that.

That is my setup. Max boost is 5 lbs. Uses extra injector with split second system. I would like to use a system that triggers at a preset boost level.

Then the Universal stage 1 kit will work for you using a DO3 nozzle or a DO2 depending on how much timing your running.

ok. How does the activator work with boost pressure setting?

dvldoc · 06-30-2008

The pressure switch works off of boost pressure, You set it to come on at 3psi of boost it will activate the pump at 3psi of boost and any pressure above that.

Can you explain how I would connect this pressure switch to my current setup?

Very simple you just tap into a boost line, The same hose you would hook your boost gauge to.

I received the kit today. Where should I mount the nozzle?

The easiest place would be the elbow right after the air filter, second would be the metal elbow right before the supercharger.
