Correct thats exactly what it does

Think of it this way the car now has the ability to advance and retard not only the spark and fuel but can now in conjunction with the electronically adjustable intake cam closly maximize the compressor map of the bigger turbo utilizing the cam gear to provide the most efficient way to spool up then to maximize top end. As a system its an awesome combo allowing the careful tracing of the most effective portions of the compressor map of bigger turbo. I would like an autocross guy to put a TME on the 9 and see what a tuner that has controll of the mivec parameters can do to spoll and midrange torque.

i believe the MIVEC helps the spool, and the bigger turbo helps the HP up top.

thats my 2c

 

Here's my sheet from past times. Hoping to see much better results with a slightly more aggressive (11.1AFR) tune this time around in May.

How much peak hp do you think the 9 would make with the stock EVO 8 turbo and MIVEC?

I would dare and say -- very little difference. Probably more torque available down low, but would still yield maybe the same overall peak.

Shiv has new maps (ie., the V3 maps labeled non-smart 330+) that are more aggressive. Have you tried them? I tried Evo Joe's Stg 0+ maps from here
(https://www.evolutionm.net/forums/sh...hlight=houston)

For my set up, I lowered the boost map a bit though. Here is Evo Joe's set up tuned by shiv:

 

Peak is perhaps similar. I believe the Mivec zeros out at 6000rpm. Which is fine if you always drive there. But before hand it's a pretty big difference. The other issue is that the 9 head is supposed to have better cooling.

 

they revised the cooling passages which aids in helping the engine to be less knock prone

 

How is he making 30+whp more power with the same mods? That's crazy! In fact, he's doing what a IX does with just a reflash! Is this on 93 oct? Catless?

I just realize that he is on 93 and catless...
So that will make a bit of a difference from your set up.

 

I agree you will surely reach ineffiency of the compressor map sooner than with the 9 turbo but you would be able to improve upon any evo8 with the help of the MIVEC. See Ted Bs posts on alternate cam gear settings and the huge torque increases he saw over all other evo8s. He manually did what the MIVEC does to the low and mid range but without the non on the fly adjustability couldnt utilize the most effiecient curve through the whole RPM range.

 

Wow. What a difference just catless with 93 octane!! Impressive!
