FAQs About Tomei PROCAM 282/282 Camshafts
What are the specific duration and lift specifications for these camshafts?
The Tomei PROCAM 282/282 set features a massive 282° duration on both intake and exhaust, with a high lift of 11.30mm, designed for maximum top-end performance.
Is it required to upgrade the valve springs when installing these cams?
Yes, due to the high lift profile (11.30mm), high-performance valve springs and retainers are absolutely required to prevent coil bind and valve float at high RPM.
What is the VALC profile and how does it benefit the VR38 engine?
VALC (Velocity Acceleration Lift Control) optimizes the cam profile to maximize the area under the lift curve for power while ensuring the lobes do not exceed the lifter edge, preserving valvetrain reliability.
Are these camshafts suitable for a stock turbo setup?
These are highly aggressive camshafts best suited for engines with significantly upgraded turbochargers and built internals intended for high-RPM racing applications.
Do these camshafts retain the factory Variable Valve Timing (VVT) function?
Yes, despite their aggressive profile, the Tomei PROCAM 282s are designed to work seamlessly with the factory VR38 Variable Valve Timing system.
