We offer valve reliefs on our pistons, also know as Fly cutting for larger cams, and lower compression ratios for higher boosted engines. This is a great addition for high-performance engines, some race applications, or those that are towing heavy and need peace of mind.
We engineer these parts for your success.
The reentrant bowl design is used to increase the temperature in the bowl to lower hydrocarbons. The reverse flow area in the pocket of the piston creates a hot spot that can lead to piston failure.
After the fatigue of the alloy, the exhaust gasses act as a cutting torch and start from here ending in a crack across the piston in the same axis as the wrist pin.
Knowing this we machine and Delip the area causing these issues to relieve it from generating these hot spots, and shortening the dwell time of the reverse flow area.
