Kelford Cams- suit Nissan SR20DET NVCS Turbo, 268°/272° / 12.00mm/11.50mm (V-188-B)

Spring pressure must match the cam profile and rpm limit. Too little causes valve float; too much causes wear.

They allow fine-tuning of cam timing, especially useful after head machining or when running non-standard cams.

For the Kelford Cams V-188-B, it is recommended to use KVS93 or KVS93-BT valve springs, especially if you plan to run over 2 bar of boost. These springs are designed to handle the increased loads associated with the higher lift and duration of these cams.

The 268°/272° duration provides a good balance between fast spool and top-end power, making it ideal for applications such as drifting where quick throttle response and high RPM performance are critical. This cam profile is designed to maximise airflow while maintaining drivability.

When installing the V-188-B camshaft, it is crucial to ensure that the valve clearance is set correctly. The increased lift of 12.00mm for intake and 11.50mm for exhaust may require adjustments to prevent valve-to-piston contact, especially at higher RPMs.

The V-188-B camshaft features a rocker ratio of 1.55 for both intake and exhaust. This ratio amplifies the lift provided by the cam, resulting in improved airflow and performance. It's important to ensure that the rocker arms are compatible and in good condition to achieve the desired lift.

When using the V-188-B camshaft, ensure that your engine's head is properly machined to accommodate the increased lift and duration. You may need to check for adequate clearance and potentially adjust the valve seats or retainers to prevent interference during operation.
