Vortech?

[5-TWENTY-3]

I'm lookin into supercharger for my 3.0 (yes I know it's the worse car for mods) and after readin a few bad reviews with PES I'm lookin for some alternatives, vortech makes a badass supercharger but sadly it doesn't seem they make anything for the a4. Anyone know of some good superchargers that you can throw me some links too or give me feed back one any superchargers you have.

The PES hardware is fine, you should just get a custom tune. Then pick up an exhaust. Like the Thermal setup I'm selling. :P

^^ I love my Thermal R&D Race exhaust, sounds great if you like it loud. can't imagine how sexy it would sound on a 3.0 with a SC.

and like sand said the PES hardware isn't the problem, it's their tune, so get a custom one and you should be good to go.

checkout this site, it's dedicated to supercharged Audi's and VWs. http://scaudi.com/ tons of great info there.
Good luck.

Buy a 1.8. Seriously though, that's my stance on it and I have a 3.0. I'd never screw around with trying to turn a N/A motor into a forced induction motor, but that's just me.

GREEDO IS RIGHT. Unless you have deep pockets, and lots of patience for a car that will never run properly.

In order for an aftermarket to grow, you need to have a few people think outside the box...

As for the Vortech S/C - I was looking at them for awhile. I wanted one that was a self-oiling unit (so I wouldn't need extra oil lines). I contacted them a few times and they never got back to me about the compatibility.

The problem with a Vortech is that they have to spool, which in turn leaves you with two bad points: parasitic power that needs to spool. And coupled with an expensive price tag like most of the units that Vortech offers, a twin-screw roots charger just makes so must more sense.

I agree completely, but there just wasn't, and won't be, enough demand for the 3.0 for any reputable companies to invest serious time into making anything for them. It's much easier for companies to run with the 1.8, since it's already turbo charged, than it is to start with the 3.0 and have to build from the ground up.

Personally I don't mind this because I'm happy with the 3.0 for what it is and know that I'll never be dumping a boat load of cash into modding it for more power. If I wanted a B6 with options to build I would have bought the 1.8 OR I'd look at doing a swap (VR6 or a 2.7t...I'd be more inclined to do a VR6 swap). Time and money spent on building a 3.0 just isn't worth it (in my opinion).

What about a centrifugal type supercharger. Maybe you could go that route instead of one with a custom manifold. Probably still won't be cheap, but you never know until someone does it.
P.S. I'm just throwing stuff out, I don't know much about them, but the look similar to turbos.

^That's what a Vortech charger is. The problem is that centrifugal superchargers have a high spool point, meaning they don't produce max. boost until a higher rev-range (think: turbo), where-as a twin screw roots charger is an almost instant boost in any rev-range.

The benefits of a centrifugal charger are that most of the time they can produce a higher boost spike (since the correlation between engine RPM and charger-blade speed is not direct), and the fact that they don't go directly into boost all the time (which could make them a lot easier to tune) since your lower RPM-range won't spool the charger enough.

Just learned something, thanks.
