Stillen supercharger long term reports

brucelidat

If I was to go turbo, it would be the Fast Intentions kit.

The drawbacks of turbo vs SC for me are:
1. no CARB sticker

2. Much higher cost, I have a 7at so tranny upgrade is needed also

3. turbos are much more complicated meaning a lot more potential for small things to go wrong or get loose, etc. which means more maintenance (I am a novice who doesn't know much about this stuff so it would be to the shop for me)

4. I have never driven a boosted car, but am told that until I am pressing the throttle down pretty hard, no boost will be made which means I will only be getting the power when I am accelerating hard whereas with SC, I am always getting some boost at all levels.

Not quite. You'll still get boost at partial throttle. It's actually a challenge to keep a turbo car out of boost. You'll likely get more boost at partial throttle than with a sc setup.

Exactly, with a centrifigual SC such as GTM or Stillen the blower has to spin up like a turbo to provide boost and does around 2500-3000 RPMs (slightly different per kit). Now if someone produced a roots blower for the VQ then yes you would have boost at anything over idle as it instantly builds.

It looks like you have been working towards getting a supercharger from day 1 (Live in Cali, bought a 7at, 4.08 FD, headers and full exhaust). Supercharger seems like the next logical step for this car. Especially if/when Uprev gets enough control over VVEL to take advantage of the extra exhaust flow. People are going to recommend you to go back to stock exhaust manifolds and cats, but I would never do it. Not for the few horsepower Stillen says you'll gain back. It's cheap and easy to just add more CFM instead (pulley down, or impeller swap).

Take your time deciding. Both SC and Turbo cars are fast. When you compare apples to apples, they both get the job done (And by apples to apples, I mean comparing a 450 whp SC car to a 450 whp turbo car). But, they both have very different characteristics. Find a way to drive both, or at least ride in both. I did not. I had the Stillen first on my HR. Then later drove a Single Turbo Z and realized I made the wrong choice. Educate yourself on the differences and how they both work. That way, no matter which one you choose, you can set it up the right way the first time.
