Upgraded valves designed for high horsepower applications! Our valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs. With every valve design, we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. It’s unlikely you will find any of our competitor’s valves with stricter dimensional tolerances than our Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere! Optimum high flow rates are achieved by ensuring that our valves are manufactured with the best angles for each application. We consider back cut, under cut and valve head angles for each application to produce the optimum high flow rates for each application. In 2006 we introduced our stem Superfinishing as a standard addition to all of our valves at no additional cost. When our Superfinish is combined with our Black Nitrided valve, it reduces the surface roughness to 1/3 of our chrome coated valve. The end result… unsurpassed performance and durability. Our exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for greater strength at higher temperatures. Black Nitride Coating: This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life. Please see below for more benefits of our Black Nitride valves. Black Nitride Coating Head Diam: 30.50mm Material: Black Nitride Groove Type: Triple Groove Length: 105.65mm Stem Diam: 5.95mm Size: Std

Generally, an intake valve is the name for a valve that allows air or fluid to pass through it, typically during the intake phase of an engine's operation. In your car, the intake valves allow an air and fuel mixture into the engine's cylinders where it can then be compressed. The valves shut during the compression phase and the spark plug ignites the air and fuel mixture, creating a force that propels the car forward. If these valves aren’t working properly, the engine will create less power and it can damage the engine over time.

The exhaust valves in your vehicle allow the exhaust port to be sealed during the combustion process, so that the engine can run at top efficiency. If the timing belt or lifter breaks, this can cause the piston to come in contact with the valve and bend or break it, causing an improper seal. This will cause a rough idle, misfires, and a check engine light condition. Be sure to replace your bent or broken valve today and keep your engine running strong.

Upgrade your M52B28 Engine with Cat Cams, a leader in the performance-aftermarket camshaft industry. These Camshafts will increase airflow into the engine by increasing the overall lift and duration over the factory cams. With their Sport cam setup, you can run all factory valvetrain, with no valve spring upgrades necessary! The VANOS (VVT) system on the intake camshaft changes the valve timing: M52 /B28: from 115° to 90° (exhaust: 105° fix) The data are shown for full intake retard (disengaged VVT). Check the distance between valves and piston to be 1mm at least with VVT engaged. Wrong installation will cause severe engine damage!

One major hurdle for a track-only car is the limitation of the hydraulic valve lifters in the M50, S50-US, M52, S52-US, M52TU, and M54 engines. These effectively limit your revs to 7200-7300 RPM as the valves 'float' at higher revs, leading to piston-valve contact. By converting to a machined solid lifter, and upgrading other areas of the engine, you can configure the valve train to withstand high RPM running. Not only can you tune for more power, you can help prevent damage during a mild mechanical over-rev.

This kit includes the mechanical spacers to convert hydraulic lifter tappets to solid lifters. The lifter bucket remains in place with the Schrick solid tappet replacing the original. These work on all M50, M52, S50, S52 and M54 engines and were proven in normally aspirated as well as supercharged engines. A custom camshaft is required.

Professional installation and setup is mandatory as these require complete assembly of the head, checking valve lash, then dis-assembly and machining of the Schrick tappet to spec. This kit includes enough spacers for 24 valves. We also carry individual parts, if you are looking for single pieces. This price is for a full set of 24.

For the US E36 M3. Schrick 264/256 degree camshafts boost mid-high end power for that extra motivation at higher rpm. Low-end torque is not seriously affected due to the M50/M52s VAN0S System. And, higher profile cams work extremely well with an upgraded intake and exhaust. When upgrading the cams there are other areas you must take into consideration. Higher-flow fuel injectors, larger mass-air sensor, and custom programming are strongly recommended. Turner Motorsport sells complete intake & cam packages that boost power to over 290hp. See the Engine section under Camshafts for more info.

These Schrick camshafts are the same specs as the stock US S50 cams -
Intake: 252 degree, 10.2mm lift
Exhaust: 244 degree, 9.5mm lift

With original S50/S52 cams in short supply, and a new set running over $2,000 from BMW, you can source new M3-spec cams from Schrick. These are the same specs as the US S50 engine and very close to the stock S52 cams. These make a great upgrade for M50 (325i, 525i) and M52 engines (328i, 528i) with the proper tuning. These bolt in just like the stock and M3 cams with no special hardware upgrades required - use your stock valve springs, lifters, etc. But for reliability we recommend replacing the lifters, valve springs, and retainers with new stock parts on high mileage engines.
