I finally got the 42#/hr Stage 2 injectors in the mail, and today was a beautiful (but hot) day to put them in!
Out with the old:
In with the new!! WIth a supercharger pulley upgrade, this will give me 50+ more HP.

Big is better!
I am likeing the air stuffer in the photo. Have you taken the car out yet a driven it? If so how do you like it and did you need to flash the ECU?
Still waiting on the pulley installer!
I did take the car out for a run, and it drives just like stock, but the redline is moved up to about 7200 RPM. Pulls a little harder, but I havne't put the smaller pulley on yet (waiting on the guy to show up with the tool) which will up boost from about 12PSI to around 14-15. As soon as I get the tool, I'll pull the blower, swap the pulley, put it all back together, and take it to the track tonight. There will be video! And yes, it required reflashing the computer to increase the redline, and change the injector flow values. Before, the injectors were maxed out around 5000 RPM, now I'm banging the rev limiter at 7200 and injector duty hasn't gone over 80%.
Nice that really should help
Nice that really should help with the launching of your car.
