I would basicly only trust Dinan and AA to do the job right in terms of forced induction. Neither of the two companies cut corners or push things to the edge. With that said, I don't think your going to see a forced induction kit for the e46 M3 for a LONG time, and when and if we do, it will be very expensive. At least 20k, give or take a few 1000.
I think the real place to look for more HP is the M3 CSL, find out what BMW did to strengthen up the engine enough to raise the RPM limit to 8500? and get that extra 47hp and keep the motor NA. |
The car did not have 47 hp extra, 7 more bhp than 343bhp stock. All the speed gained on that car was by weight reduction. Many people on this board don't undestand (not talking about you) that weight is hp and that all that matters is hp or toque per per pound. There's SO much weight that can be shaved out the E46 M3 it's not even funny. The simple things that come to mind: HEAVY back seats, seats that are fully powered and heated add in the neighborhood of 150 lbs, the moonroof is heavy (I have no moonroof). Then you can start lightening the body components, taking out the radio, ac, thinner glass, etc. The CSL comes within 10 seconds of the 996 GT2 on the nurburgring, currently the fastest production car in the world. So, with mostly weight gaining measures, a stiffer suspension and wheels that were almost slicks it nearly got the top time at the ring, but then again it's not a production car, yet at least. Why take an engine like the S54 and use forced induction is beyond me.
