How much does mivec on the evo9 help with spool in rpms of a big turbo compared to a evo 8 that has no mivec?

 

huh? the 8 does not have mivec,
but I think you mean cams right, your talking about lift not timing overlap correct?

 

I didnt say the evo 8 had mivec

 

oh I read that wrong, sorry.
well it helps spool a little bit maybe 200rpm, but the big thing about it is it provides more torque. more air during the low RPM helps "push out" the combustion exhaust, increasing VM which is a good thing.

 

Like how much more than a evo 8, what do you mean?

 

well say about 15 or so, you get more area under the curve. I guess do a search for dyno graphs so you can see.
