HKS 272 ex cam on IX

Renoevo, yes your right 23 psi is correct. Sorry to throw everyone off by my post. I don't understand...... if the intake and exhaust cams for the ix don't get any power gains at all, unlike the evo 8 do then why do vendors sell these products and have shown us and proven power gains with both cams and just exhaust for the ix? But some of us with ix's don't see it. Why?
u might have to wait until HKS releases their MIVEC controller to the states. only then will we know how the IX will do with a cam or cams. but yeah try it with a cam gear & see what happens...

hey let's see some more definitive facts like... same car same dyno same day just the cam swap, just one cam.
and let's hear why people think that there is a discrepency.
i think the way the mivec is set up the exhuast lobe centerline is at the most retarded position it could possibly be. so any addtion to the retardation through passive duration increase isn't helpful for making power.
then the intake cam is seperated by 5 degrees so the low end is great. of course there is a flaw in my theory because retarding the exhaust cam to the max would then make for a an intake that is retarded even more to make up for it.
so maybe in the end the exhuast cam has very little effect either way. and it's mostly in the intake which then can sweep the most efficient low end and then optimise top end. it is true the most important valve event is the closing of the intake...
thots people.

However, people AREN'T making power with the exhaust cam, and only the one car owned by TT made great power with the $900 cams. They may advertise based off that one car, which is proper and in no way false, but we just haven't seen regular Evo owners make good power with them...dunno why.
YOu really would have expected 400whp on pump gas with just the basic mods and cams? We haven't seen any other IX hit 375 with those mods, so I don't know where your high expectations came from. Did you think this car had a lot more mods or something? People haven't hit 400whp on alky and big boost, so I wouldn't have expected it on pump gas with the cams either. Unfortunately, we haven't seen ANOTHER IX make this power with the cams yet...
