Engine mods in N55 BMW Race Car

CRG3 · 03-26-2012, 10:12 PM

Autoweek had an article today on the BMW Bridgestone Series Race car:

http://www.autoweek.com/article/2012...NEWS/120329861

Thought everyone would be interested in the N55 engine mods and subsequent output.

"Built for the Bridgestone Production Cars category of South Africa's Wesbank Super Series and set to debut on March 31 at the Killarney race, the new 3 is a collaboration between BMW South Africa and ADF Motorsport. Due to series regulations, the N55 six-banger was left untouched internally, though ECU, turbocharger and exhaust mods bump the horsepower to 402 and the torque to 442 lb-ft, despite a 40-millimeter restrictor plate on the turbocharger inlet and a do-not-exceed boost threshold of 10.15 psi.

The car also underwent a weight-shaving program, sampling liberally from BMW's M Performance Parts bin. The diet has the car down to 2,998 pounds, a savings of roughly 600 pounds over a U.S.-spec 335i sedan"

Put on a tune, DP and a meth kit and you will have just as much power... I have no idea where all the money went in making this car. Does pulling out panels cost that much or a collection of BMW Performance parts? lol
