YES DINAN DOES OFFER SUPER CHARGER FOR THE E39 540 AND WILL PUT OUT MORE THEN 400 HP N MORE THEN 400 FLBS OF TORQUE AND WILL SPANK AN M5! THE KIT WILL BE OUT IN ABOUT 20 DAYS! AND WILL RUN ABOUT $12,999 AND LABOR IS ANOTHER $1500, I KNOW CAUSE I SPOKE WITH BOB FROM DINAN AND I AM GETTING ONE! YOURS TRULY, NICK
... or at any rate, it'll spank a *stock* M5. The nice thing about the 540/SC is that it weighs roughly 300lbs less than an M5. It's quite a package. FWIW, I also spoke to Bob last Friday, and my M5 (now with Dinan suspension) will be getting the Dinan SC as soon as it's available. With well over 500 HP, the M5/SC will spank just about everything on the road :) Ben
