[BMW M3 VLN]

If you use the VAC stroker kit that is based off of the ALMS M3 PTG race car mod you will want to go with the BMW AG Motorsport cams 316 and I wanna say 304? When you do the big cams you need to delete the vanos system. It gets in the way of the larger cams. Also the factory race cars didnt have a mass air sensor, they did use a carbon intake similar to the CSL just no giant flap to worry about before hitting that side ways filter. Also BMW AG Motorsport offers a less resteictive filter for shorter events. Incoming Air was monitored by the stand alone EMS by Motec. I have some spares of the larger cams from BMW AG Motorsport division if anyones interested?

The very first E46 M3 GT race car in the ALMS made its appearance in 2000. It was a wide body GTR powered by the S50b32 that Thomas Milner owner of PTG had stroked out to a 3.4 liter. Then came the prototype P60b40 in 2001 and the inline six dressed the same as the V8s racing right along side oneanother but the obvious difference showed in the performance. Later in 2004 came the P54b32 race engines producing 420HP FROM 3.2 LITERS. BMW. AG Motorsport offered an evolution kit to the P54b32 bumping horse power to 437 while still remaining at 3.2 liters.
