samkarp samkarp Post Master Sr Registered: 02/11/00 Posts: 5807 Loc: Milwaukee WI	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! _________________________ ~Sam Karp~ SCCA-Milwaukee "Autocrossers always make good road racers, but road racers do not always make good autocrossers."-T.C.

CSPCRX CSPCRX Jr Member Registered: 08/09/01 Posts: 390 Loc: Peoria, AZ. USA	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. _________________________ Vic 86 CRX SI (B16 Powered) (SM2 Solo2, HPDE-3 NASA & TA-C Time Attack) 13.627 @ 98.36 03 Protege5 07 Harley FXST

SIMPLE4012 SIMPLE4012 Post Master Jr Registered: 03/17/00 Posts: 1975 Loc: LAKE GROVE, NY, SUFFOLK	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? _________________________ Former Hondata tuner and currently Joe Mama

JSIR JSIR Post Master Sr Registered: 11/06/99 Posts: 6411 Loc: London, Ontario, Canada	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. _________________________ 02 S2000- Summer toy 12 Ford Explorer - Daily driver/Winter ride

SiBirdie SiBirdie Jr Member Registered: 03/29/01 Posts: 547 Loc: So cali	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!

samkarp samkarp Post Master Sr Registered: 02/11/00 Posts: 5807 Loc: Milwaukee WI	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. _________________________ ~Sam Karp~ SCCA-Milwaukee "Autocrossers always make good road racers, but road racers do not always make good autocrossers."-T.C.

DeeC DeeC Newbie Registered: 04/18/02 Posts: 30 Loc: Wpg., Canada	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. _________________________ DeeC

b20crex b20crex Newbie Registered: 12/07/01 Posts: 45 Loc: clinton mi usa	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.

tegmandan tegmandan Newbie Registered: 02/16/02 Posts: 39 Loc: Cleveland Ga, USA	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 _________________________ 94 teg gsr

samkarp samkarp Post Master Sr Registered: 02/11/00 Posts: 5807 Loc: Milwaukee WI	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. _________________________ ~Sam Karp~ SCCA-Milwaukee "Autocrossers always make good road racers, but road racers do not always make good autocrossers."-T.C.
