roller cams?

Question

what is the difference between a flat tappet mechanical cam and a mechanical roller cam?

Answer 1

if you're buying its well worth the money to get the roller
its about 30 to 50hp more with matching roller rockers
less heat
less friction
more power
dont settle for less

Answer 2

The lifter on a flat tappet cam is just that-flat, a roller cam has roller lifters which have a steel roller on the end where the cam meets the lifter, it allows you to grind a cam with more lift per durration=more power, and no break in time, they do cost a bit more, but dont really wear very much.

Answer 3

A hydraulic roller cam is extra acceptable for street applications. a strong roller cam is extra so for drag racing. strong rollers enable for larger raise which facilitates extra air and gas to bypass into the combustion chamber. notwithstanding the challenge with intense raise camshafts is that the valves would come into contact with the piston because it strikes up and down. If there is not any longer sufficient clearance between the piston and the valves, you'd be bending valves which isn't strong. For a street rod, a hydraulic roller cam is your maximum acceptable decision. no longer in user-friendly words do they function easily, in addition they provide more advantageous reliability and longer existence.

Answer 4

regular hydraulic [flat tappet] cams&lifters are simply fine polished flat bottomed lifters riding on a cam shaft on a thin layer of oil................while roller cams & lifters actualy have a roller bearing in between to improve responce while reducing friction!

Answer 5

you just answered your own question,
if it's the difference in the cam itself.
Roller tappet cams can have more aggressive profiles on them that flat tappets are not able to follow properly

Answer 6

there is a roller on the bottom of the lifter to cut down on friction. this frees hp and allows more radical cam timing :)

Answer 7

get you a solid roller cam and you can tighten it up everyday.LMAO!!!!!
