The Engle TCS-20 camshaft is Engle's mid-range TCS (turbo cam, 112° lobe separation) cam and a great choice for turbo engine builds with more performance oriented parts. The cam has a power band that comes in at about 1500 rpm and it pulls up through 6500 rpm. 1.25 rockers will bump up the revs on both ends with a range from 2000-7000 rpm. Dual springs are a must as turbo engines build RPM quickly and single springs are more prone to floating in turbo applications. The more headwork and carburetion the better to let the TCS-20 dual cam profiles work.

Engle TCS Series Camshafts are designed with different intake and exhaust profiles.

The intake profiles of TCS camshafts lift higher and are open longer than the exhaust profiles. The lobe centers on the TCS cams are ground on 112° lobe centers (instead of the standard 108°). The different cam lobes help to improve exhaust scavenging, increases torque, and helps improve power making the most of all the fuel in the combustion chamber. The higher lobe separation helps for turbo applications where the increase boost pressure can cause pre-detonation. It also helps to reduces intake and exhaust overlap which can help boost loss and improve engine idle.

Installation Notes:

All Type 1 performance cams are 3 Bolt, "early style" or "flat cams" and fit Type 1,2 & 3, 1200cc(40hp) to 1600cc based engines. The cam requires a separately sold, bolt on cam gear and must be used with a "flat cam" style oil pump. You can add the gear with the option above, or check out the links below:

• VW Flat Cam Gear - Bolt On
• VW Flat Cam Gear with Adjustable Timing - Bolt On
• VW Straight Cut Flat Cam Gear with Adjustable Timing - Bolt On

New lifters should be installed whenever a new cam is being used. Never reuse old lifters with a new cam! Here are a few of options to consider:

• Stock VW Lifter
• VW 1 Piece Billet 28mm Cam Lifters - Set of 8
• VW 1 Piece Billet 28mm Cam Lifters with Oil Hole - Set of 8

JBugs along with most 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!
