As I have said I have never owned an Evo before my current 2012 so I have no basis of comparison. I just know that overall I have not been very impressed with the Evo. I do like the car and do find it fun to drive (unless stuck in traffic). But I dont think it has lived up to the hype. But that is probably because I am stock.

I have also noticed mine has very little power after 5k. It is pretty much from 3.6k to 5k is all I get out of it. It will squeze out a little more power from 5k to 6k. But I havent really ever gone over 6k cause there is no point. I rarely will take it over 5k cause the power gain just isnt worth it.

 

it would be less than ideal if the cam profile is different and people needed to change them to make otherwise normal power- that is $$$$ we try to avoid our clients doing cams unless the head is coming off for a build!

mitsu "oh no, we are out of evo X cams..."

tech #2 "just use these TA cams... and copy the mivec tables over"

LOL!

lol. well if you ever wind up pulling a set of '12 cams and i would love to hear the lift + duration specs on it.

 

My own view point on this:
No matter what I do with MIVEC/boost/timing/fuel I am 15-20 whp below MR's with the exact same mods as me (on the RRE dyno I make 300-305, identical modded MR's make ~320, GSR ~340)
I've narrowed it down to 2 potentials areas:
1) There is a difference in the cam profile for some odd reason; it doesn't make sense for a car company to have 2 different sets of cams for the same long block, it's just not cost effective. But, I would be interested to pull my cams and send them out for measurements against MR's, just to be definitive
2)It's an aspect of increased clutch pressure; since tuning my SST, I have notice 2 things a)my car hooks up a whole lot faster b) my numbers peak at 5500 and fall after 6000. Before I had slip at peak torque (no shocker there) but my car peaked at 6500 (I'm on a TD-05 not TD-04, just to be clear).
I really think that tuning for more clutch pressure reduced my peak whp; perhaps the 12's have a different SST CPRU table?

 

Can you explain why you think more clutch pressure, thus less clutch slip, would reduce whp? It would be the opposite. Unless whatever you are using to measure WHP, isn't actually measuring wheel torque directly.

To be clear, are we talking software dyno or real dyno?

 

I wanna cry if this is true....

 

Yes sorry I wasn't clear, this was using my "VD Road of Testing"
I'd really like to get on the dyno and use my current tune in two ways:
1) Completely as is, inclduing re-done SST tables
2)Completely as is, except change back to prior SST tables (from like 4 months ago)
Being VD there is the ever present option that it was recording cluthc/wheel spin.

However, my prevailing "20whp less than MR's" is on the RRE dyno. I was at about 290ish with stock cat back. Changed out to full 3" TBE (AMS Widemouth DP, 200cell spun metal HFC, 3" Magnaflow CBE, 3" I/C w/ 2.5" piping, AEM intake with 3" inlet, GS 3-port, odd n' ends) added 1 psi to 26 1 more * of timing and made ~300. Same equipped MR's make 320-330 (3" TBE, I/C, Intake, 3-port)

 

i really doubt clutch pressure would have an effect on power and don't think the problem is limited to the MR.

anyone think mitsubishi would change the cam profile of possible their final production year? if so what would be the reason? only thing i can think of is the thought that aggressive cams blamed for a failure, possibly shortening timing chain life? all speculation of course... we need a mitsu insider.

 

2013 is the last production year for the X.. Also, I called RRE and they've said they haven't noticed a trend in 2012's being down on power.

 

Yes, in VD, if there is any clutch slip, the torque/power is artifically higher because of the way that dyno software works.

Which makes VD pretty much useless on the SST cars unless you have ZERO recorded clutch slip.

 

This is just a random thought...

There is a new timing chain on some of the 2011s (very late ones) and 2012s. The links are double the thickness. Is it possible that could cause a bit more drag than normal? Just throwing it out there on the differences between the years.

 

Really? "20** is the last year for the Evo" has been circulating for years. Basically since the MY11s came out.

 

Mitsubishi has said that 2013 will be the final production of the current Evo X. It's no big surprise, the current model has been in production longer than any other Evolution, twice as long as the 8 or 9.

Reports are that Mitsubishi is currently working on the XI.

Only time will tell, but the car is due for an Evolution soon, 6 years is a long time for an Evo production run.

Back on topic.

I had planned to go to Cobb today and do a dyno pull on the car in stock trim. I had to re-schedule for the 7th. I plan to pick up an AP when I go, gonna run a baseline for the car before I do any mods. I'll post up results.

 

Here is my Dyno done at CBRD recently on my 2012 EVO X MR. The baseline is total stock other than wider wheels (18" 9.5 265/35) . The non-base line is the typical bolt ons including upgraded frame turbo (BBX Lite ported).
