After weeks of anticipation - we finally dyno'd the IX RS with a HKS 272 exh cam. We also added a EcuTek flash. The results were rather impressive - although we didnt hit our lofty goal. But we came damn close!

TOPSPEED TUNING in GA

On the Dyno -










My car has a full 3" exhaust, intake, 272 exh cam and hard intercooler piping. These numbers are uncorrected, but you see that the torque difference isnt that much - but the horsepower is +30 with my bolt ons. No bad. Considering these mods were accomplished by spending only $700.





After just 10mins of tuning with the EcuTek software, we had gone from 274 torque to 334 torque! With no change in boost - only the EcuTek!! Thats a gain of 60lbs to the wheels! INSANE!!

Dyno Flash - 26psi - 100oct

We then added a couple gallons of race fuel to bump the octane up to 100 from 93. We also added 5psi of boost. A couple tweaks to the timing and fuel maps and we hit 380lbs of torque to the wheels!! Thats over a 100lbs gain from without the flash. Can you believe this? The IX is simply amazing.





Here is the first pull overlayed with the 100oct pull. Although we didnt hit our goal of 400 wheel hp. We came pretty close. When the vendors come out with a MIVEC intake cam, 400hp can be broken - easily. Right now, this car is a rocket - low 12's/high 11's - with perfect driveablilty and stock turbo. All these mods are simple bolt ons. And we now have a 450hp EVO. NICE!

 

Very impressive

 

damn, I don't know why I look at all the evo9 dyno number threads that get posted, all it does is make me wish I waited a little longer before I got my good stuff man, nice numbers, shows how much potential the 9's have

 

oh man... i've had my car for 6 weeks....and im so happy i went with this car over a 550i bmw...it just keeps getting better and better lol

 

Looks great. Nice combo/ #'s!

 

holy crap

 

Great numbers. I thought you said your goal was 400whp on pump gas, though, which is when we all said HELLLLLLLLLLL NO. Getting close on race gas is a much different story.

Now, considering you are putting down 380/380 on 100oct vs only 330/330 on 93 oct, that is amazing. What was the final boost on race gas and on pump gas? I only got up to 380wtq on 28psi, so I can't keep up with you, haha. I am only willing to do 26psi on a regular basis. Knowing how hard 340whp/360wtq is for me to control, I can't imagine your IX with 380/380 - oof!

One question, though...why did you switch to DIN on the final graphs? That made the numbers even higher than Uncorrected...

 

Awesome numbers! Did you, or do you plan to do more testing on pump gas with higher boost?

 

100 is pump gas, it all comes right out of a pump, at most your localk retailers, damn great numbers

 

Well, that's a technicality. It's not available hardly anywhere. It's very rare, and there are no places within hundreds of miles that offer 100oct around here. Even so, it's still considered race gas. They sell it at the track for those who want to race, and it makes a HUGE difference in the amount of boost we can run without knocking. I can go just as fast on 100oct as I can 110oct, so I buy the cheapest octane I can find when at the track.

However, if 100oct were available wherever I lived, I would use it very often - at least a 50/50 mix on every tank - but there's nowhere to find it here. Now that I'm on alky, it doesn't matter, but 100oct can't be claimed pump gas, since it's not commonly available.

 

We have a few stations with 100 oct at the pump, but it's not consistent. When one of the local stations had thier site plan in for review I talked them into adding it

I think most consider 91/93 to be "pump"

 

Is there any way you can post the actual dynojet run files? This would allow us to really get a grasp not only on the gains and powerband but on the quality of the tune. Thanx

 

Good idea. I've been doing this as much as I can as you can see in my other dyno threads. I'd like to compare the 100oct runfile with my 26 and 28psi run files...

 

well theres like three stations on the same hwy near hickory that sell 100 and as for tracks selling race gas, yes they do 110, 112, what ever you need but when i go top the track i have never seen them sell 100, must be a northern thing and then theirs plenty of stations that sell 100, sometimes you have to open your eyes a little more, kind of like their showing al in the meagan theard.

 

No, you're just lucky. It is EXTREMELY rare to find gas stations with 100oct. Just because you are lucky enough to have some near you doesn't mean it's normal elsewhere. For instance, there are 4 stations with 100oct in Denver, but there are 0 in the DC area.

Yes, many tracks sell 100oct, 104oct, 110, 112, 116, 118, C16, whatever. It has nothing to do with "opening our eyes." You can actually search and find the stations that sell it - they are listed, and believe me, I looked really hard around here, because I get a cool 30whp/30wtq right away on even a mix of 100/93. Still, as Jason also said, pump gas means 91-94 oct...
