Engle Master 2 Cam Kit - W-100 Grind With Phosphate Coated Cam Followers With EDM Oiling Hole

These super strong and lightweight chromoly valve spring retainers are designed for use on VW Type 1 aircooled 1200cc to 1600cc engines, making them ideal for both performance builds and high-quality engine rebuilds. Manufactured from Chrome-Molybdenum steel, they offer exceptional strength while keeping overall valvetrain weight to a minimum.

Each retainer is precision CNC machined to exacting tolerances and then heat treated to deliver outstanding durability and resistance to fatigue. This ensures consistent valve control at higher engine speeds and significantly reduces the risk of retainer failure compared to standard pressed steel versions. Thanks to their strength and accuracy, these retainers are considered virtually unbreakable under normal performance use.

These chromoly retainers are suitable for use with single or dual valve spring setups, providing excellent versatility whether you are building a mild fast-road engine or a more aggressive performance motor. By reducing valvetrain mass while increasing strength, they help maintain accurate valve timing, reduce wear on valve guides and stems, and improve overall engine reliability.

Sold as a set of 8, this kit supplies enough retainers to fully equip one complete Type 1 engine.

Fitting Notes & Additional Requirements

• Fits VW Type 1 aircooled engines from 1200cc to 1600cc

• Compatible with single and dual valve springs

• Designed for performance and upgraded valvetrain setups

• Always check installed height and spring compatibility during assembly

• Professional engine building practices recommended

This heavy duty valve cotter set from ENGLE is designed for use on all aircooled Volkswagen engines fitted with 8mm stem valves, making it suitable for both standard rebuilds and high-performance applications. Valve cotters (also known as valve keepers or collets) are a critical component of the valvetrain, locking the valve spring retainer securely onto the valve stem and ensuring consistent, reliable valve operation.

Manufactured to ENGLE’s high standards, these cotters are made for strength, accuracy, and long-term durability. Their precision-machined profile ensures a positive, secure fit between the valve stem and retainer, reducing the risk of slippage or failure under high spring pressures and elevated engine speeds. This makes them especially well suited to engines running heavy duty single or dual valve springs, performance camshafts, and higher RPM limits.

Correctly fitting valve cotters is essential for maintaining valve control and preventing catastrophic valvetrain failure. These heavy duty ENGLE cotters provide peace of mind in both road and competition engines by delivering reliable retention and consistent engagement with the valve stem grooves.

Supplied as a 16-piece set, this kit provides enough cotters to fully assemble one complete aircooled VW engine using 8mm stem valves.

Fitting Notes & Compatibility

• Fits all aircooled VW engines with 8mm valve stem valves

• Suitable for Type 1, Type 2, Type 3 and Type 4 aircooled engines (with 8mm stems)

• Compatible with standard and performance valve spring retainers

• Ideal for use with heavy duty or dual valve springs

• Always inspect for correct seating during assembly

These Engle 28mm phosphate coated cam lifters with EDM oiling holes represent the ultimate lifter upgrade for high-performance VW Type 1 aircooled engines, particularly those running high-lift, aggressive camshafts and increased valve spring pressures. They are widely regarded as a must-have component for serious fast-road, race, and endurance engine builds.

Each lifter features a 28mm diameter head and weighs approximately 100 grams, providing the ideal balance between strength and controlled valvetrain mass. The larger lifter face distributes load more evenly across the cam lobe, reducing contact stress and helping to prevent camshaft wear in demanding applications.

The addition of a precision EDM (Electrical Discharge Machining) oiling hole through the lifter face is a key performance advantage. This EDM hole directs a constant supply of pressurised engine oil directly onto the cam lobe–lifter interface, significantly improving lubrication where it is needed most. This dramatically reduces friction and heat, extending camshaft and lifter life—especially critical with high lift cams and heavy duty or dual valve springs.

The phosphate coating further enhances protection during initial start-up and cam break-in by providing a sacrificial lubricating layer before full oil pressure is established. When combined with proper assembly lube and correct break-in procedures, these lifters offer excellent reliability and longevity.

Manufactured to Engle’s exacting standards, these lifters are precision finished to ensure correct rotation within the lifter bores and consistent performance over time. Supplied as a set of 8, this kit is enough to fully equip one complete Type 1 aircooled engine.

Fitting Notes & Additional Requirements

• Fits VW Type 1 aircooled engines only

• 28mm lifter head diameter

• Approx. 100g per lifter

• EDM oiling hole for direct cam lobe lubrication

• Phosphate coated for improved cam break-in protection

• Strongly recommended for high-lift and high-RPM camshafts

• Always use proper cam and lifter break-in lubricant

• New lifters must always be fitted with a new camshaft

• Professional engine assembly recommended

The Engle W100 performance camshaft is one of the most popular and proven camshaft upgrades for VW Type 1 aircooled engines ranging from 1200cc to 1600cc, making it an excellent choice for fast-road and street-driven engines. Designed to deliver a smooth, usable power increase without sacrificing reliability or drivability, the W100 is ideal for small-displacement performance builds.

This camshaft provides improved valve timing over stock, increasing airflow through the engine and enhancing torque and mid-range power. It is particularly well suited to engines running twin carburettors, mild compression increases, and free-flowing exhaust systems. In a correctly matched setup, the W100 delivers a noticeable performance gain while maintaining good idle quality and everyday usability.

The W100 camshaft is manufactured to Engle’s exacting standards using high-quality materials and precise lobe profiles to ensure consistent performance and long service life. It is a favourite choice for classic Beetles, early Buses, and other lightweight Type 1-powered vehicles where street manners are just as important as extra power.

Important Fitment Notes

• These camshafts require an early-style 3-bolt cam gear

• Compatible with up to 1971-style oil pumps only

• Camshaft supplied on its own – cam gear is not included

• A suitable 3-bolt cam gear must be purchased separately (see associated products)

Correct component matching is essential. Always confirm oil pump style, cam gear compatibility, and overall engine specification before installation.

Camshaft Specifications (W100)

• Application: Street / fast-road use

• Duration: 276°

• Duration @ 0.050″: 236°

This heavy duty dual valve spring set from Engle is designed for all VW Type 1 aircooled engines, offering superior valve control for high-performance and high-RPM applications. Dual valve springs use an inner and outer spring working together to provide increased seat and open pressure, significantly reducing the risk of valve float and maintaining precise valve timing under aggressive cam profiles.

Engineered to Engle’s exacting standards, these springs are manufactured for strength, consistency, and durability, making them ideal for engines running performance or race camshafts, higher RPM limits, and heavier valve train loads. The dual spring design also improves harmonic control within the valve train, enhancing reliability at sustained high engine speeds.

These springs are commonly paired with chromoly valve retainers and heavy duty valve cotters to ensure maximum strength and safety. Due to the increased spring pressures, it is essential to check installed height, coil bind, and valve guide clearance, as some cylinder heads may require machining for correct dual spring fitment.

Supplied as a set of 8, this kit provides enough dual spring assemblies to fully equip one complete Type 1 aircooled engine.

Fitting Notes & Additional Requirements

• Fits all VW Type 1 aircooled engines

• Dual spring configuration (inner and outer springs)

• Intended for performance and high-RPM engines

• Strongly recommended to use chromoly retainers and heavy duty cotters

• Cylinder heads may require machining for dual spring clearance

• Always check installed height, coil bind, and spring pressures
