WHAT IS A CAM AND WHAT DOES IT DO IF YOU GET A BIGGER ONE? AND WHERE IS IT LOCATED ON A '98 300EX?

 

Jiz,

Contact Lauri Dunlop at http://www.webcaminc.com

They have all the info on the cams you could want.

 

I WENT TO THAT WEBSITE AND IT DIDN'T HELP ME AT ALL. I'M TO STUPID TO FIGURE OUT BIG THINGS LIKE THAT. I HAVE NO CLUE WHAT A CAM IS. THAT WEBSITE WAS LIKE READING SOMTHING IN JAPANESE AND I DIDNT' UNDERSTAND ANYTHING. PLEASE HELP!

 

jiz:

Basically, a cam is a metal shaft with oval shaped lobes surrounding it. In most cases (as far as atv's go), it is located directly above the combustion chamber of your cylinder. As it rotates, the shape of the lobes determine how far your valves open (lift), and the length of time your valve stays open (duration). Therefore, the more lift and duration a cam has, the more fuel/air mixture is delivered into the combustion chamber, usually increasing horsepower or torque (depending on the specifications of the cam, or in other words, the "grind" of the cam).

However, be warned that a camshaft by itself will not increase your horspower dramatically. To achieve optimum results, it must be combined with other compatible mods (higher flow filter, exhaust, carb, etc.). In addition, if you purchase a "wild" enough cam, it may also be necessary to purchase stronger valve springs and have your rocker arms hardfaced in order to maintain the reliability of the engine.
