Re: let me clarify I have a 330i but I am looking. (archive)

I would not go with an ESS supercharger for the M Coupe because they do not have a kit that uses the new Vortech line of superchargers yet. I believe they use the Powerdyne units which use an internal lubrication system that has proven to be problematic. ERT may... have a Vortech unit but the kit does not include higher flowing injectors which I believe is essential. Dinan is very expensive and offers the lowest amount of boost something like 5.5 psi. Conservative, pricey, but well thought out. RMS I have heard basically is like the Dinan supercharger only you get more power (7-8psi), it is a bit cheaper, has everything you need, they use new Vortech supercharger, high flow injectors, will reprogram your computer, etc. Turbocharging is very expensive and will cost you 10K or more for the Active Autowerks turbo. However there is potential for tremendous amounts of power. They have just worked out the bugs in the software for the OBD2 cars. If you want to go naturally aspirated there is also an engine offered by Racing Dynamics for the M that gets 308HP but the cost is 13k or more.

Do you have the same informatino for the M coupe?
