Engle VZ-15 VW Performance Camshaft - For 1.1 Rockers

• Old-spec cam originally designed for racing classes that required 1.1:1 rockers
• Pulls well from idle to 5500 RPM
• Best in stock or near-stock displacement engines, 1200 to 1700cc
• Great cam for smaller racing engines used in spec classes
• Fits Type 1, 2, and 3 engines from 1200cc (40hp) to 1600cc

The Engle VZ-15 cam is an old-spec cam originally designed for racing classes where 1.1:1 rockers were required. It must be used with stock ratio rockers, since high lift with stock rockers puts a lot of stress on the valve train. Make sure your lifter bores are in good shape before installing. A stock carburetor will work, as will duals to match the displacement and cylinder head flow.

More modern cam grinds and higher ratio rockers have surpassed what this cam can do, but for those on a budget the VZ-15 may be just the ticket. The VZ series cams are rough on engine cases, so sleeving the lifter bores will help reduce wear. Expect a noisy drivetrain due to the fast ramps and high lifts.

All Type 1 performance cams are 3 bolt early-style or flat cams. The cam requires a separately sold bolt-on cam gear and must be used with a flat cam style oil pump.

VZ Series Camshafts are designed specifically for use with 1.1 rockers only. VZ series camshafts with high lift and stock rockers are an inexpensive way to get more lift, which expands the power band by increasing bottom-end torque. Engle's VZ cams put more stress and load on the lifter bosses and valve springs, causing extra wear on the engine and drivetrain. This series was originally intended for limited class racing that required stock ratio rockers.

Please Note: EMPI, along with many other engine builders, racers, and auto enthusiasts, recommends using an engine oil with ZDDP or ZDTP, or a ZDDP/ZDTP additive in your oil, for all flat tappet camshaft engines.
