Chris came in a few weeks ago to get his EVO IX reflashed. We had a pretty busy day on the dyno and he didn't have the time to get custom tuned. So we flashed him with our off-the-shelf ECU reflash. His car is 100% otherwise.

He came him yesterday for a dyno test. No custom tuning. Just a few pulls to see how much power it is making. Here are the runs as tested on 91oct.

WHP and Torque:


Boost and AFR:


Stock IXs, by comparison, put down 230-235whp.

Man I Was So Happy To Achieve These Number's On A Stock Evo IX Mr With Just Shiv's Vishnu X-Flash, Baffled And Amazed To Describe It, If You Just Got Your Evo Or Have One And Plan On Modding It And Is Reading This Go With Vishnu You Seen The Results It Absolutely Crazy..... Ohhh Yea " To Shiv " Weather Permitting I'll Get You The Results On My Runs At Infineon This Saturday During Bracket Drags I'm Hoping To Pull Sum Crazy 1/4 Times To Back Up All That Power You Gave Me I'll Post The Slips Saturday Night If They Let Us Run. hahaha I'm Just Another Happy Customer. 275whp My Friend With A Gruppe-S Tuned Sti With Turboback Is Like How The Hell You Get That Much With A Flash. I Told Him With The Power Of Vishnu ha ha GOODNIGHT EVERYBODY

 

Well its threads like this that make me happy. Im going to be getting a xflash on my stock IX at dyno4mance. These numbers make me happy in the pants region ...and just think ill be running a custom tuned flash with 93 and not that horrid 91 you guys have out on the left coast

btw grats on those sweet numbers MyLuckyIX

 

Running all that boost on 91 oct. just scares me

 

okay.

 

I have My Trust In Shiv And His Product And I'm Not At All Worried The Only Thing That Scares Me Is Not Living Up To The Cars Expectations, Other Than That Everything Is Running Fine, And I Push The Car Real Hard When Raced....

 

i think it would be a safe assumption to say that Shiv would not run that type of boost on 91 unless he was absolutely sure that the car wasnt knocking all over the place. Im also curious to see how much farther Shiv can take this with some custom tuning. I guess if he doesnt do it on Chris' car, he'll have to do it on my car but with 93.

Shiv, have you found the IX's to be more knock resistant than the VIII's even with 91? Does the redesign of the coolant passages in the head have something to do with it or is it the mivec pulling timing? Inquiring minds want to know

 

I Wish I Could Of Got A Custom Tune But Cash Is In A Bind Right Now As Soon As I Get Rid Of My Other Car I Can Start Putting More Money Into My Evo, But Next I Plan On Doing The Vishnu Sig. Exhaust And Then The Vishnu Cam Gears Hoping To Pull 300+whp,,," Shiv How Can I Get That Vishnu Tuning Decal That Go's On The Rear Window Am I Worthy Of It Yet " ; )

 

Correct me if Im wrong but you would only want to put a cam gear on the exhaust cam since the intake cam has the MIVEC cam gear. Unless Im mis-understanding your post, I think cam gears would be counter productive.

 

I'm Not To Sure Lets See What Shiv Will Say

 

From what Ive read the MIVEC cam gear on the intake cam is infinitely variable. Putting the gear on the intake cam would limit you to a set timing, and that would negate the purpose of having MIVEC. As far as putting one on the exhaust cam, I could see that as having potential if someone is able to identify a timing setting for the exhaust cam that would work well the ever changing setting of the MIVEC cam. Im curious to see what Shiv has to say about this as well.

 

I'm not questioning shiv's tuning abilities at all, in fact I plan on getting tuned by him this summer. I'm just saying that 24psi on 91 is scary because on an VIII this would be suicide...apparently the MIVEC and IX ECU allows you to run this much boost safely. Hats off to the IX and shiv!

 

Just wait till this thing get's a custom tune....

 

Hmm.. he's running way more boost at the lower rpms - clearly showing that magnesium compressor wheel spooling up faster. Shiv really tuned my car very conservative. Notice how the IX really loses boost in the upper rpms where my boost falls less (this isn't an apples-to-apples comparison, but interesting to look at). My AFRs are also richer than the IX's (which might attribute to more prone to detonation or could be just a really conservative tune), but more flat. I think with an 11.1 AFR target in the mid-range (assuming no detonation), I could get another 10-15awhp.

FYI, we don't get the magnesium compressor wheel in the states.
