Tomei CAMSHAFT SET PONCAM SR20DET (R)PS13
TA301B-NS08ARegular price $959.99
Utilising cutting edge VLAC profile technology the PONCAM 258° camshafts combine the stable idling and low to midrange performance of a 256° camshaft together with the top end performance of a 264° camshaft.
In addition, they also feature the highest lift amount that’s compatible with the stock valve springs for increased flow rate and higher output. The PROCAM is designed for larger turbo setup and high rpm us making it ideal for drift, track and drag race applications.
The VALC profile allows the valves to open faster and for longer. This translates to faster lift and increased area under the 'lift curve' (see fig. ①)
which in turn generates more power. (Greater area under the 'lift curve' = greater air intake
Unlike the valve opening, the VALC profile ensures that the valves close at a slower rate, helping to prevent common valve train related issues
Highest lift amount that's compatible with the stock valve springs for increased flow rate and higher power output.
Machining each lobe to the strictest tolerances allows for smoother and more precise adjustments in valve clearances.
Based on: 12.50mm max lift, Φ32 base circle
