A local brought his new Evo 10 over to our dyno today to get some baselines.

I can talk about the 10 but pretty much everyone has seen the photos and reactions about it already.

Here is some data. This is a low-reading Mustang dyno.

100% stock Evo 10 with 840 miles.

Three baseline pulls back to back:



Boost and AFR: (23psi peak dropping to around 13.5 at rev limiter / AFR 9.7 to 9.4 up top)



100% Stock Evo 10 overlayed with a 100% Stock Evo 9 on our dyno: (Dotted lines are the Evo 9, solid are the Evo 10)



100% Stock Evo 10 and 100% Stock Evo 9 boost and AFR: (Dotted lines are the Evo 9, solid are the Evo 10)



My observations:

It's rich as hell. It was actually choking on itself from 5500 rpm or so to redline. The Stock Evo 8's and 9's do this as well, but not until around 6900 and to a much lesser extent. I would give a good guess that it might be running a bit too much timing up top for 91 from looking at how the curves are. It looks like Mitsu put a 3 bar map sensor on the 10 so logging boost through the ECU without buying a "JDM" map sensor will probably be a reality when Evoscan/Mitsulogger is updated for the 10.

I'm excited by the possible potential of this car from just tuning it, when we can.

We should have a couple more stock 10's coming in soon to get more data.

 

^yea. did you see how much power it picks up when its tuned/ leaned out!

 

Damn cant wait to see some reflashes and other mods on the X.

 

damn, this car is running rich as hell!

 

Wow blue looks sooooooo nice

 

someone needs to strap in a universal aem ems and lean it out then dyno

 

Thanks for sharing the info man!

 

I am worried as to why they have the boost taper off so fast and get so rich in the upper revs. Was Mitsu having problems with the tuning? That is alot of peak boost from the factory. I hope we are able to steady out the boost and lean the tune out with still having safe tune with no knock. Thoughts??

 

So if i read it right, the X does that numbers in higher boost , but more richer, right?
The same time IX it does it, less boost but leaner? Also over 5000 rpm the IX makes more power and tq?

 

Thanks for posting. I think this is the first Mustang Dyno charts posted.

Just for ***** and giggles, do you happen to have a dyno chart for a stock IX from the same dyno? Just curious to see how the curves differ.

 

LOL did you even read his post?

He has both graphs up there.

 

That's good tq.

 

Funny. The IX is not only lighter but more powerful, too. Thanks.

 

Ummm....yeah...I ride the short yellow bus

 

the 9 is more powerfull wow
thanks for sharing this
