Sam,
Thanks, I just started shopping for cams and was not sure which to go with for the cash. Crowers sound like they might be the best bang for the buck.

No problem guys.

The biggest thing I learned is what different cam company likes best....lift or duration. JUN is by far a duration company. They have much more duration than others on the list but hella less lift. Good for people running high dome pistons but adding lift really helps more IMO.

As for mixing/matching cams. I wouldnt do it. Maybe a JUN II Intake/JUN III Exhaust but still yet they are made to work together as a set. If there was duration/lift/power to gain by mixing and matching then they would do it themselves.

Another thing I learned.....I was really underestimating the JUN II cam. That is a hell of a cam that almost no one uses(Joey does I think). It is closer to JUN III than I thought it would be. Probaly just a little less power over 8200rpms but mainly thats it!

Yes he did. You may be able to find the post on Honda Tech. I think I've got the link saved somewhere, I'll see if I can find it.

So the Crowers are no good. Well then I guess its JUN3 cams for me. But I have heard of people having problems with the JUN 3s binding the valve springs even the JUN springs. Anyone have any feedback on this. Fact or Fiction? I have a B16A1 and i want to get the most out of it without taking the motor down completely. I have been told the JUN3 will give the most HP.

fiction........I have never heard of this in a JUN setup.....

The cams beaking however is not unheard of...But onyl when abused and taken where they shouldnt be. They become very unreliabele at around 9700 or so. But then againnnnwho cares about 9700?

nice compilation Sammy ! , if you hear of Jun cams or most other cams causing binding of the springs, it is almost always an installation error, where improper installed height was used or not checked. Sometimes the wrong springs are used with the wrong cams, but usually it is a problem with the installed height.

im just curious, have anyone dyno skunk stage 1 vs ctr/itr cams? Do both of them make good mid range power? To me from looking at the specs, it seem like skunk stage 1 will make more power since it has more lift and dur. ? What you guy's think ? dyno polts will be excellent thank you!

Anyone know if the Skunk2 Stage 3 cams will have the same problems I've heard the Skunk2 Stage 2 cams have had? I'm talking about the lobes on the shafts wearing out after a while...btw make this post sticky!

This page is a sticky at the time.

I have not heard of any problems with the "new batches" of Skunk2 cams. Skunk2 admits that there were wear problems a few years back with their cam but I have not heard of anyone having a wear or breakage problem ever since the "new batch" came out. Atleast I have'nt heard about it here.

My two cents:

1. Kick ass research. Way to go!!

2. I'm sure that most of you will know this, but for those who don't.
Since the max flow through the intake ports is determined by the port geometry, adding lift will only help till the port flow is maxed out. After that any extra lift won't help(unless turboed). Whereas adding duration will always increase the amount of intake charge flowing into the cylinder, regardless if the port flow is at its max.

Just something to consider for those without head work.

the people that break cams are the ones who dont have a clue were the valves need to be lashed at or what spring to run not knowing that info will result in binding for sure.to much spring pressure.

which cams would be good to use in my ls/vtec engine. I have the stock 1st gen b16a cams and the vtec engagement is very mild, in sound that is anyways.

I was thinking of just changing the intake cam but I want to find one that will "POP" the loudest when VTEC engages.what makes the "POP" louder lift or duration?

please help me. thanks, Daniel

OMG.

You dont want pop...or a noticeable transition. You want a nice smooth transition when you hardly know that VTEC.

Unless you want to just have your car sound good and not have it make power.

Look at the post below this one for LSVTEC advice.
