I would like to know if someone install those camshaft on your EVO and degree the cam by refer to the centerline, which is 104/112? What's the teeth shown on the cam gear? My car is JDM EVO7. Appreciate if someone can provide such information.

 

That will vary depending on the engine build up, if I understand you correctly. I think you are asking where to put your adjustable gears in order to get the 104/112 location? Normally that would be zero and zero on the gears unless machine work to the motor has changed the distance from the crank to the cams.

 

I had HKS 272/272 camshaft before and I need to change my gear to -4/-2 in order to match centerline 110/110 as stated by HKS. That's my question on Compcams.

 

Bump?

 

It's impossible to say. The manufacturing of cams is not perfect.

But when you run the cam straight up (0 cam degree on pulley), that should then equal the centerline values the manufacturer recommends.

99% of people on this board just put the cams in straight up and don't degree them. But the fact you had to adjust your HKS cams so much concerns me. I degreed a pair of HKS 272's and they needed only about a half cam degree or so to be right inline.

Did you degree your HKS 272's?

 

Honestly the HKS 272 seems to be such a reliable cam and grind. I would suspect the reason you had to go -4/2 to get them to 110 is because of an issue with your block or cylinder head skimmed maybe. And if this is the case, then I would just run the Comp cams at that same setting.

Best case is to degree the cams but failing that I would run whatever you ran for the HKS 272's and in doing so you are hoping the 272's were not the ones off it was the geometry of your motor.

 

The motor is full stock. Putting HKS cam 272 straight on and found the car has loss power. After degree the cam and make adjustment on the cam gear like -4/-2, the car become much more responsive again.

 

That is odd... I don't know. It's just a guessing game if you don't degree the cams properly. In the case of guessing, do what you did with the HKS cams, install them straight up and tinker with them.

 

For HKS cams, I degree them properly with cam degree kit in order to get -4/-2 on cam gear to achieve proposed centerline 110/110. I just want to have a reference point on compcams.
