Camshaft STREET 11.0mm Lift High Performance
[SA424]
$395.00 $348.00

STREET PERFORMANCE

Our street performance 2.0 10.5 test engine made 171 HP with very good low end torque and idle.

Street High Performance upgrade for all Weber and Spica cars. Our #424 11mm cams are similar to the factory AUTODELTA 11mm 1750/2000 performance profile with the modified opening profile for  good lowend torque and idle.  Midrange and top end are superb with no flat spot. Duration 254 degrees @ .050" lift.

There are three setups.  Mid-range will be about the same with all three setups. 

  1. A pair of these will be aggressive enough to be strong up to 7500 RPM, with great top end for track events and still be docile enough for street.
  2. For street performance with emplasis on low end performance, substitute our 11mm 425 cam on the exhaust side.
  3. Enhance top end for those track days by using our 12mm #445 intake with a #424 exhaust.
  • Bolt in with no clearance issues with any piston. 
  • Use our basic VSS12 performance valve springs.  

FEATURES:

  • Bolt in with no clearance issues with any piston. 
  • Our cams have super durable lobes that are first hardwelded before precisioon regrinding.
  • To minimize lobe interference with follower bores with high lift performance cams, the base circle is undercut to 1.030."

All new and reground cams should be installed with new followers.  There is risk of damage with old followers. Unfortunately, there are inferior quality followers on the market and we can only guarantee satisfaction with Spruell Motorsport followers. 

CAMSHAFT EXCHANGE CORES REQUIRED

Sorry, but we are no longer able to fill customer camshaft orders without exchange cams in hand.  Even after we upped the core charge from $50 to $75, very few cam cores were returned  -- NO EXCEPTIONS.  ADD $65 FOR SET OF FOUR FOLLOWERS.
