Need suggeston about cams wth following specs:
272/272 adv
242/242 at 1 mm
11.3/11
26-66/64-24
If I made correct calculations specs are
LCA-110/110
Which positon should be zero point for mivec cam (evo9)?
manufacturer suggest 112 like peak timing for both cams...I understand that this is evo 8 intake lca more or less, but how it correlates to 130 for all mivec intake sftermarket cam?

With an EVO 9, the intake centerline is advanced from its very retarded base position using the MIVEC table. That is a very long duration cam, and I would consider advancing the exhaust cam about 2 degrees.

For exhaust already checked all position s +/- 6 degrees from centerline. Best power at +5, best torque at -5. But what about intake? I can move it equal to 1 tooths i.e 100, 114, 128.
The reason why MIVEC is on the intake side and not the exhaust is because the engine is much more sensitive to changes on the intake side, most particularly, the closing point of the intake valve. In consideration of that reality, unless the Exh LC is deemed to be significantly out of kilter, I see no real reason to do anything with the exhaust cam on a MIVEC engine. More or less everything the user needs is a matter of tuning the intake cam LC (and LSA) dynamically with respect to rpm and load.
Ok, thanks. Wasn't planning on changing the exhaust cam timing, but was just checking your thoughts. I got an adjustable cam gear because it was much lighter than oem
hi ted, What would you recommend For evo 9 Mivec Wagon
tomei 280/280 11.5mm lift solid type
Atp GTX3582R turbo bolt on turbo
Arc IC And pipe
twin plate cusco
How many cc Injector have to use ?
What is the setting for the cam Gear ?
You will use MIVEC to adjust the cam settings electronically while the engine is running. You do not need an adjustable cam gear. One who understands cam timing dynamics and the programming can do far more with MIVEC than an adjustable cam gear.
If you want to lighten things up on a MIVEC, you can find an adjustable cam gear that is much lighter than the OEM unit. But those things tend to be cumulative...so you may not notice anything from just that.
I have a Evo 1 and I've just fitted new Kelford 272's and a custom td05 20g 6sl2 11 blade billet wheel but I'm finding it very laggy ie peak torque around 5000rpm
I've set the cams to +2 ex and +1 in
What else would you recommend to get earlier and maybe higher torque
