My Stillen super charger story....

Osiris

I will try to keep my review fair and to the point. Keep in mind i am not a professional driver and i don't have any track experience. so the point of view is that of your average joe daily driver with a led foot and past speeding tickets to show for it!

So my setup is as follows: Stillen super charger, high flow cats, cat back exhaust, and racing oil cooler. *Obviously the oil cooler has no impact on performance; just cooling. I should also note that i originally started out with the silver (lower psi) pulley and above config minus the high flow cats. Without the HFC, the car had more noticable power, however, I did not feel the added power until i hit 5500 rpm and above....at that point the car took off. I was told by more than one person that it was very quiet for a super charger.

In come the High Flow Cats; with this addition alone, it was like someone took the cork out of the bottle. Not a major power increase, but enough of a change to notice. The car flowed better from 1st to 2nd to 3rd primarily in the below 5500rpm range. At this stage the car had been tuned by Horsepower Logic in West Palm Beach and was pulling 343WHP on a Mustang dyno.

Next change was the original pulley (higher psi). With this addition, Horsepower Logic did a re-tune and now the car is pulling 390WHP on the Mustang dyno (see below). The power comes on in direct correlation to the throttle position. And i have to say, with the addition of the high flow cats, the car now has a distinct sound on the outside. Before, people were saying they didn't really hear much from it. Now it sings!

I know some of you will ask, so, i use 93 octane, and according to Horsepower Logic the car is running at approx 9.5 psi. This is my first car review, so i apologize for anything i left out; let me know if there are any questions. Here is the dyno:

*i'm sorry, but i don't have a pre-super charger dyno
