N\A turbo question?

Tyler,

My set-up is: a mild-street-port S4 6-port motor (9.4 comp rotors), T04 turbo, external wastgate w/10 lbs spring, 720cc secondary injectors, TII AFM, Stock S5 NA ECU, etc.

The build thread link below, start with post #52

This car has run great for me, even though I have to peddle it around 6 psi cause it has a 10 lbs wastgate spring.
After 6psi it starts running lean.
If I put a TII fuel pump in it, it would probably help.

So assuming you have a TII motor and TII ecu, then making sure you have the TII fuel components, you could run that motor with the 9.7 comp rotors on the stock TII boost (8 psi?) for now until you get a aftermarket ecu.

But don't take my word for it.
My motor is the spawn of 2 to 3 different rotary experiments over the past few years using what I have. One of my rotary friends calls it "satan's rotary", lol.
