Mac Performance
 
Dual CP3 kit, a much need accesory when wanting to acheive that 500hp+ build.
all kits come with a full plug and play setup.
 
Possible to mount this kit on both iron and aluminum blocks.
It contains all the necessary parts for a complete conversion.
 
Increase fuel supply AND reliability with dual CP3 high pressure injection pumps. Two independent pumps are far more reliable than even the highest quality modified single CP3.
Decrease drive load & stress on the factory timing chain system.  The M57 timing chains have been known to fail even in stock applications, while driving a stock displacement R70 CP3 pump at stock fuel volume.
Avoid increased drive load on the already highly stressed timing chain system.  This occurs when the factory single R70 CP3 is upgraded to a higher output single R90 CP3, and is largely dependent on the fuel volume being commanded / supplied by engine tuning, injector size, etc.
The additional belt driven CP3, instead reduces load on the factory timing chain drive system by over 50% since drive load is transferred to the serpentine belt system (which is more appropriately suited to handle increased drive loads).
Dual CP3's also allow for the second belt driven unit to be over-driven at a higher RPM based on pulley ratio, and thus supplying a higher volumetric flow rate per engine revolution.
This kit is compatable with either an  R70 or R90 CP3 (some R70 and R90 CP3’s from non-BMW applications may not be compatible due to various vehicle specific configurations from Bosch).
Individuals who have already replaced their factory R70 CP3 with a larger displacement R90 CP3, have the ability to conveniently utilize their original R70 CP3 as the second belt driven pump and in return reduce timing chain drive load below that of a factory single R70 CP3.
