wałek rozrządu ze zbyt długim czasem otwarcia zaworu Explanation: street use because it produces so little power at low RPM, causing poor drivability. (See What's a 3/4 Race Cam?) In order to gain power with a high performance (longer duration) camshaft, you must have an engine which is capable of reaching the higher RPM levels. For example, no matter how much duration you have, a stock Model T motor is never going to turn 5,000 RPMs. To achieve higher engine speeds you must have a head and manifold that will flow freely and a high enough compression ratio. As an example, a stock Model T has a 4:1 compression ratio, poor air flow and a poor head design. Several years ago, we discovered that all of the reground camshafts available were too big, i.e. too much duration. This is called overcamming an engine - a very common mistake when building an engine (see Monroe). One dyno test showed that a stock cam (218 degrees duration) produced the same peak horsepower and up to 15% more midrange power. The midrange power is extremely important for driveability with only two forward gears. http://www.tildentechnologies.com/Cams/CamPerformance.html -------------------------------------------------- Note added at 2 hrs (2018-07-01 23:03:15 GMT) -------------------------------------------------- cccccccccccccccc Po angielsku się też mówi o aggressive camshaft, czyli o wałku z agresywnymi krzywkami, więc overcammed byłoby ze zbyt agresywnymi krzywkami. |
