You're asking me why you would want to upgrade just one cam? I don't know why you would, but in your last post you asked if an Evo VIII could make decent power with one cam. I have no idea why you'd ask that then say that I'm wasting your time when I answer the question. You're not making any sense.

 

I think that the stock factory VIII cams are a staggered setup. The intake cam is longer duration than the exhaust cam. Correct me if I'm wrong, though.

You could, theoretically, change either the intake or the exhaust cam on an Evo VIII to, let's say a 264* and leave the other cam stock. This would be a really mild setup. No one has done it as far as I know.

Is this something that you are seriously considering doing to your Evo? IMO, you would be better off doing both cams as this is proven to provide the greatest increase in horsepower at a minimal sacrifice in driveability, especially if you stay with 272's or milder.

Now, your question as to whether the Evo would make power with only one cam, was probably asked without really thinking about what you were saying, right? The Evo engine is a dual overhead cam design, and thus by definition the infernal contraption requires two camshafts(one exhaust, the other intake) to achieve at least a hope of internal combustion, even on 91 octane **** gas.

 

so i talked to this guy supposedly his specialty is in cam instalations and he told me that my problem maybe that the cams need some degree .,is this true ,is this the same as alingning the cams for timing?as you can already tell i know nothing of this so no jump on my case if i sound ignorant,thanks

 

They need some "degree"? That's all he said? Maybe he knows what that means, but you don't (as you admitted). It's possible the cam timing is off, and it's possible he's referring to using cam gears to retard or advance the timing to make the most power. A more knowledgeable person like MalibuJack or Zeus probably knows what that guy means.

It could have to do with the complexity of the MIVEC and the installation of the intake cam going wrong. Since the shop who installed the cams was not an Evo shop, you may want to have this guy take a look. I would want someone who has experience with doing cams on a _Evo_ MIVEC head, though.

 

thanks im not sure if your'e being sarcastic but it does make sense so im going with it ,thanks

 

No, not being sarcastic - just trying to help.

 

hi everybody ,hey wartalon thanks for everything ,i just came from the reflash although the number werent what i expected but nothing that cant be fixed,the car ran smoothly and made 401whp the first then 398 ,preety much stayed around there so im happy ,and yes you helped a great deal man thanks again ,later

 

Haha, wtf, you were expecting more than 401whp??? Jayzus...
