Brand: Tomei
Product: Bery-Ring Exhaust - R35
Part Num: 161109
SPECIFICATIONS:
Material: Beryllium
FEATURES:
The function of which valve sheet is asked, is maintaining air tightness with a valve, and generally wear resistance is required. However, with the engine used by high rotation and high load, the cooling performance of a valve sheet becomes very important further, and it is greatly concerned with an engine output. When engine is high rotation and high load, it is impossible to achieve high output from the engine if cooling performance of the cylinder is low and knock limit does not become high, since the temperature of the circumference of a cylinder head rises unusually. In racing engine that temperature needed to be carefully controlled, how much you can cool the circumference of the sheet ring is the important issue, and the technique of using high heat conduction metal, such as copper for a sheet ring, has been taken. Copper has one of the highest thermal conductivities through all metal that enables receiving heat from cylinder and cool it down quickly by transmit the heat to the cylinder head. (Degree of heat conduction: 1.silver, 2.copper, 3.gold, 4.aluminum, ... 10. cast iron - STD). Tomei select beryllium copper alloy (BeCu) that can secure mechanical intensity most in the copper alloy, which has ideal fatigue resistance and wear resistance while securing a preeminent cylinder cooling performance. Tomei named it bery-ring and applied to the high performance turbo charged engine. of market share in the world with beryllium copper so that tomei can offer this super-high grade material beryllium in affordable price.

Adjustability, strength and ease of movement Review by Wesley
Cusco quality, allows for caster adjustment up front
Cusco quality Review by Wesley
Easy install, makes a good difference
Noticeable Difference, Fast Shipping Review by Wesley
Ordered this and a few other Cusco items for my ER34. Easy install, great quality
Fast Shipping, Tein great for upgraded Ride quality Review by Wesley
Great Tein Quality, Fast Shipping, Very well packaged
Perfect for GTX Turbos, where the internal wastgate is too small. Review by Philipp
The quality is typically HKS perfect.The price-performance ratio is very good and there is no other option on the market where you can increase the spring preload. It would be nice if HKS would bring another 40mm version onto the market with a smaller housing. Because it's not that easy to accommodate such a large wastgate in the engine compartment.
