Pure Tuning Evo IX Parts Dyno Testing & Results BASIC PERFORMANCE UPGRADES THREAD

[Keith-PURE Tuning]

Mitsubishi Evolution IX MR with 1500miles on Odometer.

Parts testing will be progressive with parts being bolted on taking convenience in mind. Parts are bolted on without tuning unless specified. When we conducted these tests we tried to take it from the consumers view which was to bolt on the parts and eventually get them all tuned in.

Test are performed on our Mustang Dynamometer MD-1100-AWD-SE

Fuel: 93 octane
Atmospheric Temp: 69Deg
Relative Humidity: 55%
Stock Intercooler was retained of the duration of these tests

Stock Vs ARC Intake Box, Greddy Titanium Catback Exhaust, DC Sports Downpipe, Custom Aluminum Upper Intercooler Pipe by Pure Tuning w/HKS BOV & Hallman Manual Boost Controller. The boost controller was still set at stock boost level. The primary purpose for the BC was to smooth out the boost curve which it did. :mitsu:

Tuning was required at this point since the air fuel was starting to lean out at the bottom end. We wanted to bolt on each part listed on this last test and dyno them one at a time, but time caught up with us and with the customer deadline approaching we bolted on the remaining parts and tuned everything in place.

Final Boost Level was 22psi on 93 Octane

We performed these tests to show that bolting on parts can still result in very good horsepower numbers without tuning. I still feel tuning is still one of the best modifications for any car on any setup, but most people like to purchase a number of parts before they get their car tuned because if they change or upgrade parts after the tune it will need to be tuned again. After performing these tests on this Evo IX I was shocked to see how flat and stable the A/F was on the stock computer up till the last test. I personally feel people don't give the stock computer on the Evo IX enough credit. The final graph does show the parts with a fully custom tuned computer.


Thanks for viewing,

Great post. It is like the "Power Pages" in whatever import mag but without the misinformation and bullshit. We all know how big of an impact simple breathing mods have on these cars but it is cool to actually see the curves and how each is affected mod to mod.

KILLER POST! This makes decision making a lot easier for some folks, when trying to decide who get's their hard earned dollars!! Nice work Keith

[Kratos]

Most impressive indeed.

Very nice work. Great contribution to the board. I am sure similar results will occur with any combination(name brand wise) of basic performance upgrades. Would you agree for the most part following this (and obviously I know it would depend on the tune) that similar results should be expected with similar parts? Or are there parts in the basic performance upgrade category that tend to yeild better or worse results?

Somehow, we are going to find ways to make Keith's post sticky, or easy to find. These are amazing posts and what anybody who has a bone stock evo should follow this guide to doing mods.

Thanks again Keith

Fantastic real world information here. this will help a lot of new Evo owners judge for themselves where the best bang for the buck comes from.

I think I'm going to point everybody who calls me to this thread! Awesome stuff!

[Evo9]

very impressive! thanks for doing the test!

This was a great post.
Im curious as to the knock level before the tune. Since i see a very noticeable increase in HP after the tune, so I assume knock was in check and had room to go.

Great work anyways. PS does Aaron still work there?

[SteelCityEvo8]

Awsome information for people to see.

Thanks for the efffort put forth in the testing. Great results

Excellent post. This will save a lot of people money, thinking that they need a tune after every mod. It's probably a good idea to have a wideband 02 just to be sure that your not running to lean after each mod.

I am not too good at looking at dyno chart, but the power is pretty liner for a turbo charged car?
