KOMO-TEC 280S Kit on my 2007 Exige S

[eas]

Great write up! Hope to see this beast in person one day, just not at a red light

Ivan - thanks for the air filter! You wouldn't believe the filth on the old one...

The first ride:
The first ride I went on was as a passenger with Courtney the owner of EU AUTOWERKS driving. From the moment he started the car the sound from the virgin exhaust was pure & throaty. The mechanics that did the work were grinning from ear to ear as they did their final check looking for any leaks or loose connections. After the car warmed up, we headed out onto the road for a short drive to the highway. With the engine temperature up and the 6k rev limiter satisfied. Courtney accelerated along the sweeping turn and onto the highway.

The first reaction was violent unbridled horsepower resonating right through your seat. The acceleration was ridiculous, the sound from the supercharger through the KOMO-TEC intake was like listening to a turbine spooling up on an Abrams M1A1. You could actually hear the release of pressure in between shifts in audible "puffs". If you didn't know better, you would almost think it had a wastegate. As well accelerated through the gears, we passed cars like they were standing still. Courtney turned off on the exit ramp and we came to a stop at the lights. The engine just purred, the temperate was perfect, the idle was perfect, no blips or walking like the problems i had had with the old ECU (I had, as most here, idle and stalling issues). A smooth low RPM loop and back on the highway we went. The car repeated the same events on the way back to the shop. Courtney's comments were "this is by far the fastest Exige S I have driven, the power & torque comes on on demand in every gear even at lower RPM's, just incredible!!" Back at EU AUTOWERKS the crew once again went over the car looking for any issues and found none.

My turn at the wheel:
On the drive home I eased into the throttle for the most part really paying more attention to the idle at the lights and just enjoying the sound of the exhaust. I have had the pleasure of having the factory muffler, the original Stage II as well as the new Stage II exhaust on the car and I was hoping to get the best of both the latter two units. The sound is for lack of better description just a sweet note. As the night progressed and as the exhaust started to break in, it just got better. There is a long, newly paved sweeping right then left turn along the route and I just couldn't resist the temptation to push it. All I can say is "Holy @%$#!" the power is clean, smooth the road melts under you and the sound is intoxicating. Idling along through my neighborhood, I felt like proud father bringing home my 5th child for the first time.

Later that night:
I decided to take the car out for a few more hours of run time and to push the new KOMO-TEC juiced engine to its limits. The weather conditions were dry and a little cool. Other than all of the observations mentioned above, the first thing that you realize it that you have to stay focused when kicking it. The tach needle bounces off the rev limiter so quickly you have to stay sharp to hit the next gear. I like to drive with the traction control disabled and with the new power in low gears the rear got loose a few times as the tires struggled to put the power to the road. You quickly learn the curve and compensate feathering the pedal. Pouring it on when the tires bite brings water to your eyes. I kept saying to myself "this is how the car should be, a pure unadulterated attach on all the senses". Over the course of the night the car ran flawlessly. I turned to head home twice but couldn't make the final turn and just kept driving.

Before I get a barrage "DYNO PROVE IT" posts.... Yes, I do plan on getting it to the Chassis DYNO shop shortly. =

[T.O. Exige]

Here is the results of the Dyno runs on Friday night.

Sorry the scan is a little blurry but the numbers to the rear wheels are:

Horsepower = 253.16
Torque = 167.03

Add in the drive train parasitic loss of XX and you get Horsepower = ??? at the flywheel.

The car is running on Sunoco 94 Octane pump fuel. According to Daniel at KOMO-TEC, the numbers are in line with expectations based on the mapping required for the lower 92 octane North American fuel. Daniel is sending me 2 new ECU's to see if we can squeeze a little more juice out of the engine. I'm going to go back and have some additional runs done when they show up.

On another note. I drove the car in downtown Toronto Stop and Go traffic on Sunday in the heat. The engine temperature never went above the standard 207 degrees with no noticeable heat soak lagging during short accelerations. Last year in the same conditions the car would shudder in the high temp stop and go when the traffic opened up and you stepped on it.

Thanks a lot for the Dyno printout! That means you have a different mapping for the North American fuel than we have in Europe, right? What is the highest Octane you can get there? Would be interesting to see if Daniel can tune a little bit for this fuel because I think he has not much experience with it.
Has Daniel also commented the drop when the cam shifts at 4.6krpm?

This from what I understand the first KOMO-TEC S280 Kit to ever be installed here in North America. The highest Octane we have here at the pumps is 94. You could by Octane Boost and blend your own but its not practical for me.

Regarding the lower cam shift, I asked that question as well and was told it was the sweet spot in their experience for tracking the car. He is doing an evaluation on all of the data and will be sending me a report shortly.

Keep in mind that octane ratings in NA and Europe are not measured the same and therefore produce different numbers. I don't remember where the equation and explanation are, but it's out there somewhere.

Here is a little info on European vs North American octane rating I found...have a look.

Originally posted by E_SolSi@Jul 17 2005, 12:48 AM
In Europe 98-octane gasoline is common and in Japan even 100-octane is readily available at the pumps, but this octane nomenclature is misleading to Americans as foreign octane ratings are derived entirely differently from our own... So, like every other measurement system it seems that everyone else uses a different scale than we do, but unlike most other instances where we have had the good sense to create different units of measure in this case we all use the same name...
Japan and Europe use a system called RON or Research Octane Number to determine the octane rating of their gasoline, while stateside we use a system called AKI or Anti-Knock Index to determine gasoline's octane rating... Interestingly, to further complicate things it would seem that our own AKI system is actually derived from the average of the RON system and another more complicated system referred to as MON or Motor Octane Number... So, to recap our methodologies for measuring gasoline's octane rating are different, but share some common elements...
So, with the commonality of RON in mind a good rule of thumb is as follows, multiply the foreign RON Octane rating by 0.95 and you will have the US AKI equivalent.

( RON Octane Rating x 0.95 = AKI Octane Rating )
98 RON Octane x 0.95 = 93.1 AKI Octane (US measure)
100 RON Octane x 0.95 = 95 AKI Octane (US measure)

So, as you can see the 93 or 94 octane fuel we are all paying an arm and a leg for is actually quite comparable to the higher octane fuels found in Europe and Japan. The people whom have to worry about low octane rating are our friends out west in places like California that are subjected to substandard 91 octane.
91 AKI Octane (US measure) = 95.5 RON Octane

[probax]

That's interesting, I didn't know that one. I always wondered why the octane labels at the pumps in the US stated less than in Europe.
Ok, now we know there is no difference regarding the gas quality but then I'm wondering why the torque and power is much lower than expected.
@ T.O.: have you also done a dyno before the modifications?

[uglyduck]

Where did you get your dyno test done. Chris and I have been meaning to get our cars tested

The Company's name is Magnus Automotive located in Concord.

[uglyduck]

Great, I'll give them a call

[shay2nak]

what was your hp and torque before?

[andrewgotanelise]

very impressive

[Faizan21]

wow just went thru this whole thread.., and i liked what i read
couple of questions tho, i see that ur the first in NorthAmerica with this kit... very nice,

so does that give us in the States a chance to also get this kit... say we talked to 'Daniel' in germany and we could get this komo-tec kit shipped straight to us in the States???

and what if we're already planning on getting a different exhaust and decat, etc... could we still get our own exhaust and stuff, and have them tune the ECU with those mods included? or do we have to purchase the exhaust and sportcat that is extra with kit?

from wat ive been reading, this seems to be the best kit for the 08 exige S40s... also utilizes stock SC, altho pricy, but has promising gains... also sounds SICK from the video. plz post more vids if u can?

Putting your own exhaust and cat to the car should be in principal no problem but the ECU mapping is tuned to the devices Daniel used. So worst case is that you have to live with less performance. Daniel is very helpful to tweak the max out of the car, maybe then he can also give you different ECUs to test. I'd give him a call and ask him about: +49 2652 989536

hmm thanks.
well ive been doing some research on diff. exhausts and cats, and which ones have best sound and performance... but if the exhaust and cat that comes from this komo-tec kit are one of the best in both sound in performance, than i dont mind spending the extra $$$ to get it, epecially cuz the ECU mapping will be the best... but i cant see the ecu mapping mattter that much even if i get it mapped with Daniel's setup for those two, and going with a different tuner's... ill just wait and see on some more input perhaps. and can someone confirm if getting this kit available in the states is possible? i figure if OP can get it shippd to him in canada, the US shudnt be a prob either...

[probax]

You can order it at Hangar111.com. I don't see any reason why this could not been shipped to the states.

Any news from T.O. Exige about an ECU update from Daniel?

I see that Komo-280 is no simple performance trick to make the Supercharger perform harder - instead it is an engineering solution.

Tell us where in America that this performance upgrade is currently being instsalled?

I'm very interested, as well. However, I don't think there are any distributors in the United States at this time. If there are, please let us know about them. Does anyone have any information? I guess a phone call to "Hangar 111" would be the next step.

Also it is worth considering the other choice, Gotham from CharlieX and a Proalloy charge cooler, IMHO these are the best items on sale for the S to give long term reliable performance for track and road. Well I would say that as I own one

Yes, I agree completely. 'Gotham 265' from CharlieX and the Pro-alloy charge cooler both get my very enthusiastic thumbs up. Moreover, IMHO there is probably nothing else that gives as much 'bang for the buck' as Charlie's 'Gotham.'
