razorlab's simple build(s)

After selling my beloved 400hp E85 2010 Ralliart Sportback, I picked up a 2013 VW Golf R. Drove that for almost a year and decided to get rid of it and pick up a 2014 Evo GSR with the SSSL package (Sunroof, leather, HID, Fast Key, upgraded stereo, etc) and get back to Mitsubishi.

Hey look, it's a stock 2014 Evo GSR:

My idea going into this build was to see what the car can do with "simple" modifications along the way.

For example, I was always curious what a relatively stock Evo 10 could do on E85, nobody was really doing this because most people modify the car a bit more before getting tuned, which brings us to this first round...

I baselined the car 100% stock with about 500 miles on it. Then I tuned it with no physical modifications to the car. Only an ECU tune.

You can see the results of this here:

Red plots = 100% stock
Blue plots = 100% stock with ECU tune

Image


Then I put a couple more miles on it, and at around 950 miles I tuned the car on E85 with only these modifications:

ID 1000cc injectors
Blaqops fuel pump kit with Walbro 255
Speed Circuit resonated test pipe
GM 3 port boost solenoid

That's it. Basically two power mods and two fuel mods (for E85). The car sounds pretty much the same as stock and obviously looks 100% stock.

Green plots = 100% stock
Blue plots = 100% stock with ECU tune
Red plots = With modifications listed above, ECU tune and E85

Image


So now I wonder no more what a Evo 10 will do with E85 and almost no modifications. I guessed the car would maybe do 100whp more then stock and I was within 2whp of being right. Keep in mind it's also not just a peaky gain, the whole power curve is so much fuller now the car is just a joy to drive now. Power on demand. One thing to note is that I am purposely keeping the low end boost down as to not overwhelm the stock clutch. I could get a bit more torque out of the car but I am currently choosing not to.

This is an AMAZING value for the money. The car is totally transformed power wise.

Now, as you can see in the plots, the car is a bit choked up with the stock intake/filter so I'm going to install a AEM intake very soon and see what difference that makes.

I also have a set of Bilsteins from a MR and Swift R springs I will be putting on the car soon.


Alrighty, update! Added an AEM intake

I guess these intake thingies work. ;)

Red plots = OEM intake
Blue plots = AEM intake with no tune changes

Image


I was actually surprised it ran less boost down low but not surprised it ran a tad more boost up top.

Not a bad gain. Guess it was pretty corked up.

Next I tuned it a bit for the AEM intake. I decided to keep the boost lower in the low and mid range (stock clutch) and raise it a bit 5,000 rpm up.

Red plots = OEM intake
Blue plots = AEM intake with no tune changes
Green plots = AEM intake with tune changes

Image


Even more gains. :) Pretty impressed actually.

Full gains from after tuning:

Red plots = OEM intake
Green plots = AEM intake with tune changes

+33 whp / +12wtq

Image


Full gains so far from OEM bone stock:

Blue plots = OEM stock Evo 10
Red plots = Intake, Test Pipe, 3 port BCS, Injectors, Fuel Pump, E85, tune

131 whp / 93 wtq

Image


Pretty darn happy with that.

Now to figure out why my IDC's are so high at 92%. I suspect the in tank fuel hose...

Interesting results!

Is there a build soon to follow? Or is this it :dancebanana:

I think you should try a cosworth panel before you go aem.
I have a HKS panel sitting around that I could throw in and see what it does. Might be an interesting test.

I did it awhile ago on the 10's on the Mustang dyno at GST and saw almost zero difference between the OEM panel and aftermarket panel when tuned (not tuned was a different story), but that was on 91 oct and not the boost I am running on E85.

Might be worth a try.

This is just proof that the car's safe potential is mostly underutilized from the factory. Imagine what the naysayers would have thought had the X come from the factory with just a more aggressive tune and upgraded boost solenoid? Even on 93 the gains would be noticeable and would totally change the initial perception of the platform.

Razor, you've always impressed me with your professional, scientific approach to tuning, and I always loved your Ralliart build. Glad to see you back, man.

I forgot what a stock 10 felt like. It's sloooowwwwww... my first WOT in this 10 when it was stock was very underwhelming... probably one of the reasons I added 100whp before it even hit 1,000 miles....ahahh

Welcome back sir!

Carry on with scientific research and awesomeness.

Leaving the current gain over stock graph here.

Tomorrow the car is getting some attention to it's looks and handling instead of power. New wheels, tires, Bilsteins, swift spec R springs and alignment.

Very surprised by the intake gains, especially since the AEM intake reuses the factory snorkel. I always thought the narrowest part of the snorkel (where it meets the box) was the restriction on the stock intake. Now I would guess the filter is most restrictive on the stock system which makes me wonder if similar gains can be had with just a drop in.

Any dramatic temperature differences between before and after intake logs?
 
#37 ·
The secret is running the AEM intake without the lid. ;) It's a good compromise between a totally open intake and this. It still shields a good amount of heat. I ran the AEM intake without the box on my RA Sportback because it wouldn't fit and never ran into problems actually.

I discovered years back on a 500hp BBX evo 10 that the lid creates a vac at higher airflow and actually causes the induction tube to collapse. Took it off and boost went back up and HP went up. Obviously that proved that the OEM snorkel is a restriction at some point.

Thanks. Useful. Keep it coming!

So I found out that you have to basically slam the Evo 10 if you don't want XXR's to stick out ghetto style in the rear... big bummer as I'm not planning on slamming the car so I think I might be selling these wheels. They look great other then that though. :-/

I need the ride height and the Spec R springs are pretty much perfect for me....

I'll try to get better photos over this weekend.
