Im looking to do a pulley setup in my 03 cobra. I picked out a Steeda 2.81" supercharger pulley, steeda idler pulley and sct programmer. is this a decent setup for street use? If not let me hear wut u guys would reoommend to do? Im looking to make some decent horsepower without blowing my car up.
 
i would go with a billetflow 2.93 upper, 2lb lower, and a 100mm idler. You could also upgrade to the billetflow idlers. Then get the blower ported (stage IV) and get it dyno tuned with the SCT x-cal 2. Easy way to get 500rwhp.
 
I wouldn't go with anything smaller than a 2.93 on the stock blower. Any more boost than that really just turns the M112 into a giant heat pump and heat soak ensues. If you want to run something smaller than the 2.93 or want to add a lower get the blower ported first.

The SCT programmer is a great choice, just don't rely on the tune that comes with it. You'll want to get the car on a dyno and have a pro tune it. Those tunes that come with the handheld tuner from the manufacturer are really not that good. Spend the extra money to have it tuned properly.
