Hi cam are cams that are mounted at hi altitude to snap hi quality images.. They serve to increase speed by using the most advance.... Just listen to boosook.any expertist can brief me why people use hi cam to increase speed? how does it work? what are different with normal cam?
"water drop shaped" - the word you are looking for is "cam profile". High cam is where the cam profile loop is bigger to provide more valve lift, and the cam profile curvature is smaller to provide longer time for valve lift (for more air intake or more exhaust out)its very technical, try reading "how engine works" first at www.howstuffworks.com
for high cam or performance cam, the degree of the "water drop shaped" thingy the moves the valves at the camshaft is different from stock. different degree gives different loop time. longer open loop time will give u more air thus more fuel is mixed thus better combustion = better power.
correct me if im wrong.

u made my day.. LOL!Hi cam are cams that are mounted at hi altitude to snap hi quality images.. They serve to increase speed by using the most advance.... Just listen to boosook.
sifoo.......Hi cam are cams that are mounted at hi altitude to snap hi quality images.. They serve to increase speed by using the most advance.... Just listen to boosook.
anyway, hi cam will exert more stress to your valves because of the more sharp curvature on the cam profile, which might shorten the life of the stock valves.. correct, sifu sekalian?Hi,if i change to hi cam...do i need to install piggyback/safc as well?

and now gasoline price went up ad, dun use high cam lo.. use more fuel oni.. haha
no ah? i tot i read it somewhere.. when i found the info then i paste back here la.. ahhanope... valves are not wear n tear item... sharp curvature of the cam lobe means higher lift on valves to allow more air/fuel to go thru....
camshaft with high lift recommended to upgrade stiffer valve spring... stiffer valve spring allows valve to go up and down fast and precise so ur piston wont hit ur valve...
sifu sky,i'm using 4g13p...satria mmc batch.i plan to install hicam to increase torque.what duration do you suggest? do i have to change the valve spring as well.how much ar?:hmmmm:nope... valves are not wear n tear item... sharp curvature of the cam lobe means higher lift on valves to allow more air/fuel to go thru....
