Camshaft STREET (Columbo & Bariani) 12.0mm Lift More Performance Increase
[ARST-1]
$225.00

STREET PERFORMANCE INTAKE CAM

(NEW -- No Exchange Necessary)

This is a great street performance upgrade for all Weber cars. This 12mm  C/B INTAKE CAM is the tried and true Columbo & Bariani street performance camwith good low end torque, better midrange and a lot more top end than a pair of C/B #425 10.9mm cams.  Duration 254 degrees @ .050" lift.  TOTAL DURATION 292. 

  • Installed as INTAKE CAM it makes a smooth step up from stock cams, and brings the engine power a pleasant boost by raising the torque curve mostly on the top end.
  • Install with our 10.9mm Columbo & Bariani ARSM-2 as exhaust cam to maintain low end and mid-range performance. 

PORTING:  Cleaning up the bowls from valve seats to back guides is quite sufficient for street performane cams without enlarging the runners.  Full porting is marginaly appropriate for street unless you plan to do track days.  Enlarging the ports enhances gain from midrange up and pays handsomely above 7000 rpm.

VALVES:  Enlarging the window into the chambers with our 1mm oversize valves is equally valuable and lets cams have full affect for both street performance and race.

HEADERS:  Cam and porting do make a big difference on their own, but these enhancements will only reach their full potential with our Spruell Motorsport free flow headers.

FEATURES:

  • The base circle is unduercut to 1.025." (standard is 1.080") on this high lift 12mm performance cam to eliminate lobe interface with follower bores.
  • Bolt in with no clearance issues with any piston. 
  • Use our basic VSS12 performance valve springs
  • We strongly recommend upgrading to VSS12-1 springs for 11.6 and 12mm lift cams.

All new and reground cams should be installed with new followers.  There is risk of damage with old followers. We can only guarantee satisfaction with Spruell Motorsport followers.
