Crower, Comp Cam, ETC there cam specs are like Pri-Sec-Mid

If there are 3 lift and Durations how come everyone says there are 2 profiles on VTEC cams, when there are 3 lobes that are different?


Wouldn't it be really be 6 cams in one engine instead of 4.

beacause there is 2 profiles, but 3 different lobes.
outer 2 and then the middle one

 

Alright that clear up my understanding, thanks.

So it would be 6 cams in one engine, as I was saying above.

I'm not stupid, each lobe has different specifcations meaning the 2 outer lobes arent the same.

That would be 6 cams in one engine.

 

six cams in one engine? hrmm.... thats a lot of vTAKKKK
no matter how different the lobes are there are still only two cams

 

Maybe your "mid ship civic" has six cams...

I did'nt know this is where retards try and take a whack at tech questions.


No not six cams EQUIVALENT TO 6 camhshafts since all 3 lobs have different specifications, if you not gonna anwser my question why bother making stupid *** comments.

 

the primary and secondary lobes are different but work at the same time in the ''low rpm cam'', they are different to promote swirling and a more even burn in the combustion chamber.
the mid lobe, well is the high rpm cam lobe.

 

Six different cam profiles - two cams - simple.

 

but when you are in vtec, the out lobes arent doing anything, so they are disregarded, on the middle lobe is doing the work. there is still only 4 valves per cyclinder
