How does one find out about ancillary changes for the IX? Sure, Mitsu will tell you about MIVEC, but they're not going to mention a higher flowing fuel pump.

By way of comparisions a Evo 8 on the same dyno would make about 320 max on the same 100 octane
A full Buschur Stage IV on 100 octane would have a hard time to make the same power - in fact it would be in most cases about 20 whp down
I knew the Evo IX was going to make insane power levels when I was in AZ on this past Sat and dynoed over 300 TQ and WHP with a similarly modded IX on a Mustang dyno with 91 octane - that is equal to about 325 - 330 on this Dyno Jet which is again about 25 - 30 whp more than a Evo VIII would make on similar mods

I'd like to see someone put an EVO9 16g on a bone stock EVO8 and see what the results are. The IX numbers are impressive.. but not enough for me to even consider trading in on one.
Anyone know off hand if Buschur has had any 9's on their dyno?

But seriously technology and design is what makes for great turbos and
really outdid themselves with this new unit. It spools very fast and makes mad power ! Great combo

I apologize if this has already been discussed, but are the IX's higher torque figures more a result of the new snail, the variable intake cam, or a combo of both? Until now I always thought engine stroke was the overriding factor when it comes to turbocharged cars putting down more TQ than HP, but I believe that's always been the same on the 4G63.

Also - notice the variation in the shape opf the TQ curve from 3600 through 5100 rpms
The IX stays much flater and broader through the 4500 - 5100 range while the 8 seems to fall flatly all the way down
Its the MIVEC working which is keeping the TQ greater in the mid range
More boost generally equals more TQ so the 3500 TQ figure is much closer between the two cars
However - if you look at the TQ at 7,000 rpms you will not a serious advantage for the IX over the 8 - and the MIVEC is set to zero advance after 6,000
This shows the turbo makes most of the power while the MIVEC helps alter the TQ profile

I think I did about 5 dyno pulls in a row at the same power level and drove the car to veirfy how it was pulling
Today I dynoed a evo 8 and the dyno is still working 100%
The facts speak for themselves
