Web Cam Type 1 Camshaft, Grind 218, 1.1 or 1.25 Rockers, 00-382 is designed for 1.1 and 1.25 rockers, and it's specs are .455" Valve Lift with 1.1 Rockers, 280 degrees of advertised duration, and 242 degrees of duration at .050" checking clearance. This is an awesome turbo cam in turbocharged street engines when ground on a 112 Lobe Separation angle! For a Type 1 get this on a 105LC. This is also a great choice for bus and type 3 engines in the 1800 - 2100 cc range.
We refer to this cam as the "Turbo Plus" cam. This cam likes good flowing heads, and is a FANTASTIC cam for mild turbo engines when used with a 112 Lobe Center. It's also great for Baja Bugs and Class 9 SCORE cars. The cam looks like it's aggressive due to the pointy lobe, but it's actually not. This cam just doesn't hold the valve open at full lift for very long, which gives some people the impression that it's "aggressive". This is a great bus cam for small and medium sized engines (Mild strokers)!
This cam works fine even with stock heads, but it's performance is much better with some porting, and especially if larger valves are used. Expect a power band from 1000 to 5500 RPMs, the more head work and carburetion the better the top end will be.
We recommend HD single springs for 1.1 rockers, and dual springs or beehives for 1.25 rockers. Use a compression ratio of 7.75-8.25:1 in Type 2s and Type 3s, or 8.75-9:1 in Type 1s.
If you choose to use this cam with 1.25 rockers, you will get another 2-300 RPMs at the expense of valve train life.
LOBE CENTER: The proper term is really "Lobe Separation Angle", but people more recognize "Lobe Center" so that's the term we have used here. Lobe Center is a VERY complex topic, generally speaking a smaller (Narrower) Lobe Center will improve low end power at the expense of top end, and a Wider Lobe Center will do the opposite. Of course, duration does the same (more duration helps top end at the expense of low end), but it's just another way to further refine your power. If you do not know what Lobe Center to choose, the VW Standard is "108 Degrees" and you won't go wrong with that (if you didn't know, we would send you "108 Lobe Center").
We offer a range of Lobe Center options for guys that have researched the topic thoroughly, and want to order a cam with a specialty configuration.
CAM CLEARANCING: Select the Cam Clearancing option for stroker crank on long stroke engines! It's needed on all 82mm or longer strokes, and SOME 78+mm crank/rod combos (VW or Porsche journals). It depends on the size of the big end of the connecting rod, but USUALLY the bigger the rod journal the bigger the big end of the rod. Generally speaking H-beam rods have a smaller "Big End" than I-beam rods do, but the only way to know is to check. If you aren't sure, just pay up for the "Cam Clearancing" option for the most room on your engine build.
