Brian Crower cams for the 2008-2013 Mitsubishi Evolution X are manufactured to exacting precision. Brian Crower high performance Evo camshafts are ground on state-of-the-art CNC cam grinders to ensure accuracy and tolerances to within .02mm. Every Brian Crower Evo X camshaft profile has been prototyped and dyno tested for proven horsepower results prior to being produced. By grinding cores in high volume, Brian Crower, Inc. is able to pass the cost savings on to the end user. Brian Crower produces first-rate cams at affordable prices.
All Brian Crower Evolution X cams are checked on a high speed, sub-micron accuracy measuring gauge. Brian Crower uses an Adcole Camshaft Measuring System with individual measuring heads for each cam journal and cam lobe. This instrument has .01 micron resolution, taking one datum point each 1/10th of a degree or 3,600 data points per revolution. Up to 200 Brian Crower cams per hour are checked for errors in rise and for any chattermarks.
Evo X cams are available in 272°/272° and 280°/280° specifications. We suggest using Brian Crower Evo valve spring and retainer kits for the 272° cams, and it is required with the Evo 280°/280° cams. Don't let the pricing fool you, these are excellent cams for your Evo at a great price.
Brian Crower 280 degree cams have a longer duration profile and added RPM potential. Intended for fully built engines, Tuning and ECU mods recommended. The BC valvetrain kit below is required for engine longevity.
