I'm seriously considering putting a supercharger in my 2004 M3 (end of extra weight b/c of convertible issue for me then).
BMW would like to see me Dinan products. The positive is that my warranty will still be valid after installation. The negative is the HUGE costs.
The original product I am looking at is the vf-engineering supercharger (see http://www.vf-engineering.com/
) which is about $12K (US) installed, has 3 year warranty but if something goes wrong my BMW warranty would be null and void. However, it seems like a great product and problem free. You get about 450 horsepower and torque goes up to about 330 (yes, apparently it is like flying). They are made for BMWs.
My questions is, had anyone any news from anyone who actually has installed the vp-engineering supercharger? Comments please!!!!
Thanks in advance!
P.S. Check this video, made by vp-engineering for their supercharger.
