Hey..

I just put CTR cams in my stock B16A2 (170 HP JDM)

I hear the vtec kick in (5800 rpm) and it lacks power until 7500 rpm..

like my stock A2 cams were better then the CTR's.. is there anything i need to make these cams wake up??

 

Also put the same in my 00 SiR (Ferio) just recently. Pulls harder (and faster) in the mid rev ranges now that when vtec kicks in I don't feel as much pull as when I did with the stock cams. Is that what you're experiencing too?

I don't claim to be a tech guy at all, but I think since the difference between the, um, normal lobes and the vtec ones in the stock cams is bigger as compared to the difference between the ones in the CTR cams, the "shift" to vtec is much more noticeable in the stock cams. (Anybody care to confirm or correct my very crude and unlearned analysis?)

Have your car dynoed and tuned to be sure. Peace.

 

While the cams alone may add a few horses, they will work better if they are used in conjunction with other parts that increase the efficiency of the airflow through the motor. I.E.-ITR intake manifold/TB, ECU reprogramming, cam gears, etc. Also like it was mentioned earlier, dyno tuning.

And especially higher compression. A good idea would be to get some adjustable cam gears and tune the cams on the dyno to where you want the power. This isn't really a bolt-in kind of thing, it requires a little more work to see full benefit.

 

You need tuning man, take it to a dyno. I had the same thing with mine, noticed a drop in low end and mid range.

 

do you see the same prolem when going with Skunk stage 2 cams, or JUN stage 2?

 

Yes.

You will see these problems with any cam change if you don't have other necessary mods to get benefit out of the particular cam..
