W-140 Camshaft, .465 Lift, 313 Duration, Off-Road Comp

OVERVIEW

When you are ready to move beyond the limits of a street-friendly cruiser and step into the realm of serious competition, the Engle W-140 Camshaft is the legendary choice that delivers the high-RPM punch you crave. Designed specifically for competition drag racing and aggressive off-road builds, the W-140 is a high-lift, long-duration beast that transforms a standard Type 1 air-cooled engine into a high-performance powerhouse. This cam is engineered for the builder who isn''t afraid of a radical idle and demands a power band that screams all the way to the top end. With its .465-inch lift and 313-degree advertised duration, this camshaft provides the massive valve opening required to feed large-bore cylinders and high-flow cylinder heads, ensuring your Volkswagen stays ahead of the pack whether you are hitting the dunes or the drag strip.

Crafted with Engle''s signature billet strength and uncompromising reliability, the W-140 is built to withstand the extreme stresses of high-performance racing. This isn''t just a component; it''s the heartbeat of a precision-tuned engine. To extract the maximum potential from this grind, you will need a supporting cast of high-quality valve train components, including dual valve springs and chromoly pushrods. Because the W-140 is designed for "bolt-on" style gears, it offers the timing accuracy required for high-revving applications. When you choose Engle from Appletree Auto, you are investing in decades of racing heritage and a camshaft that has powered more winning Volkswagens than almost any other brand in the industry. Prepare for a significant increase in mid-to-high range torque and a horsepower curve that doesn''t quit until you do.

PRO TIPS

1. Prioritize a Proper Break-In Procedure

The first 20 minutes of a new camshaft''s life are the most critical. You must use a high-quality assembly lube on the lobes and the faces of new liftersnever reuse old lifters with a new cam. Upon initial startup, immediately bring the engine to 2,0002,500 RPM and maintain that speed for at least 20 minutes. This ensures the cam lobes are properly splashed with oil and "mated" to the lifter faces. Always use an oil high in ZDDP (Zinc) or a dedicated break-in additive to prevent premature lobe wear on flat-tappet setups like the VW air-cooled engine.

2. Verify Component Clearances

With a high-lift cam like the W-140, "drop-in" installation is a myth. You must check for "lobe-to-rod" clearance, especially if you are running a stroker crankshaft, as the cam lobes may physically strike the connecting rods. Additionally, you must verify "valve-to-piston" clearance and ensure your valve springs do not reach "coil bind" at full lift. Because this cam produces .465 inches of lift, dual valve springs are mandatory to prevent valve float at the high RPMs this camshaft is designed to reach.

3. Optimize Your Induction and Exhaust

The Engle W-140 is a high-duration camshaft that moves a lot of air. To see the performance gains you are paying for, you need to match it with the right supporting parts. This cam performs best with a pair of dual carburetors (such as Weber 44 or 48 IDFs) and a large-diameter merged competition exhaust system (1-5/8 inch or 1-3/4 inch). Using a stock restrictive exhaust or a single small carburetor will "choke" the engine and prevent the W-140 from reaching its power potential in the upper RPM range.
