Why choose matched valve springs for performance cams?
Spring pressure must match the cam profile and rpm limit. Too little causes valve float; too much causes wear.
Do I need adjustable cam gears?
They allow fine-tuning of cam timing, especially useful after head machining or when running non-standard cams.
What are the recommended valve clearances for the Kelford 188-A camshaft?
For the Kelford 188-A camshaft, set the valve clearances to the manufacturer's specifications. Typically, intake and exhaust clearances should be set according to your specific engine setup, but a common starting point is around 0.10mm for both.
What type of valve springs should I use with the Kelford 188-A camshaft?
It is recommended to upgrade to Kelford's KVS93 or KVS93-BT valve springs when using the 188-A camshaft. This ensures proper valve control at higher RPMs and prevents valve float.
What is the expected power range for the SR20DET with the Kelford 188-A camshaft?
The Kelford 188-A camshaft is designed to improve low to mid-range power and throttle response, particularly when paired with 54mm-60mm turbos. However, actual power output will depend on the entire engine setup, including tuning, fuel quality, and boost levels.
Do I need to adjust the timing when installing the Kelford 188-A camshaft?
Yes, when installing the Kelford 188-A camshaft, you should consider adjusting the cam timing to the suggested centre lines of 108 degrees for intake and 112 degrees for exhaust to optimise performance.
Can I use the Kelford 188-A camshaft with stock components?
While the Kelford 188-A camshaft can be installed with stock components, it is advisable to upgrade the valve springs and ensure your engine is properly tuned to handle the increased performance characteristics.
