Magneson supercharger on a 2.5

[tim986]

I have a kit on my Boxster they work well only down fall is the squashed part of the pipe leading to the Supercharger from the intake.

To tune mine properly I added a UNICHIP piggy back and disconnected the 7th Injector as the standard ones will flow enough fuel without it.

What i wanted to do was work out a way to enlarge the squashed part of the pipe make up a smaller pulley for the super charger re connect the 7th injector and run more boost.

But I bought the 996 Turbo so the 986 got put on hold.

Any how what you need to do is buy a unichip an old one will work fine ( i bought mine from a guy on this site for 200 bucks) put it on a dyno and properly tune it.
A custom ceramic coated exhaust (keep the heat away from the supercharger), a bigger throttle body and a IPD Plenum will also need to be added if you want the maximum out of it.

After a lot of playing for I ended up with just under 180kw at the wheels which for the little 2.5 on 5psi of Boost is wicked, thats the same power as a 3.4lt 911
.
If you want to re-fresh the super charger before you fit it you can get a rebuild bearing kit on ebay for around $100 bucks.

Good luck with the build brother, they are such a brilliant car to drive up in the mountains.

Cheers,
