i wish i knew how to read the AF graphs and tell whats good and bad. i dont really know anything about AF =/

 

You're absolutely right in what you say. I'm not blind to that fact.

This is why after talking to Cole, we're both in agreement, it needs to be rerun as a direct result of the A/F graph. He's agreed to run the stock intake first, then the injen or ours, then the next intake as third or fourth depending on if ours goes second or 3rd <-- convoluted way of saying Injen and Umnitza in any order AFTER the stock airbox with the others following behind.

That being said, each dyno can be different. So we're going to run an isolated dyno and monitor our own A/F readings this Friday night, sooner if possible.

Our test will only account for the stock runs then the intake we carry.

We're hoping to get the positive results we "feel" in our back sides.

One thing Cole also agreed to do is add the "sound" of the intakes to the testing, as the aural sensations are part and parcel of this product.

 

good luck guys, prove us something went wrong with that dyno.

I have faith i bought a great product from a great company.

There has to be more to it than just this

 

Yes, that is true Dynos should have HP, Torque, AF and Rice levels all taken into account.

:D

 

Thanks for the Awsome dynos...you are a true asset here and this thread needs to be given a sticky for power hungry ASAP!!!

GSC,
Did you happen to get a hold of draxas so we can see a dyno of their exhaust....i know you said there is some "sooper secret stuff" but i am very anxious to see some numbers on them....Either way, YOU GUYS ARE GREAT!!!!

Keep up the great work

No seriously, part of the enjoyment of our cars is the sensations they give us aurally.

I don't like fart can or whiney sounds, but when Mustang drives by, I take notice. Even though it's no faster than my M3, it sure sounds good:D

 

[quote="ColeGSC"]here ya go
Cole, one more request, can you make sure the car is run in a closed loop mode.
on BMWs it's 50 miles to redo the setup.

The richness of our intake AND the leanness of the Injen makes no sense on these tests

 

Ok guys. After brainstorming, I think I found your problem.

Your using a Dynojet which is not a load bearing dyno correct? If you are resetting the ECU and then letting it relearn on the dyno, your A/F ratio will of course be off. Also, your timing will be off because the car is not seeing any load.

Try resetting the ECU and driving on the streets for a little while. Then perform a dyno test when the ECU has learned correctly. I bet you will see different numbers and A/F ratios!

Give it a try....

 

Exactly right, we did this brainstorming ourselves too just now

 

i dunno if this has been requested or not due to the long long thread and many pages i didnt read..


how bout puttin the INJEN filter on a different pipe. say the K&N pipe or the WR pipe or the FUJI pipe...

will that mak much difference?

 

Which was a point I think I made back on page one.

What these tests truely show is which intakes airflow the ECU can most quickly get used to.

Although someone countered that.

Either way, clearly some intakes do show gains, and some do not.

 

With all due respect to our experience (not as great as some on here) we've been thinking this through more and more...

If an airflow of one intake is 800cfm and the next intake is 900 and the next one is 750, even with ECU resets, the car really needs to learn for about 30-50 minutes of solid driving in many different conditions what is going on. But, if there is a significant change - where an intake suddenly produces 400cfm or (what we assume to be true on ours but need more data to back it up) 1100-1200cfm (all arbitrary numbers for illustrative purposes) then the ECU will adapt by throwing more fuel into the stream, to prevent problems that would ruin the motor.

This seems to jive with the data you see where Stoich hits rock bottom on the intake we provided and stays there and returns back on the others.

This implies 1 of two things, either our intake gives a significant drop in over cfm (not likely but possible) or a significant boost in cfm (we have to wait to see).

This is just further analysis, I'm still kind of surprised at the data, but I'm sure with more testing, we'll have better information.

 

We are going to drive around with the Umnitza intake on the car for the rest of the week. We will give it PLENTY of time for the ECU to learn.

We will dyno it again at the end of the week.

 

Agreed, to a degree.

 

What will that show.

It's no use unless there is a comparison.

 

Granted that the dyno test for each manufacturer's intake was done with identical procedures (ECU reset, same number of runs, ect), I think it would be fair to say that the tests were NOT faulty. If each intake got equal treatment, then there can be no arguement as to which intake the ECU learned better. The parameters are the same, and the ECU learns at the same pace each and every time. This was a shotgun, heads-up style dyno test, so it's either you make the power, or you don't. If Umnitza gets a week of flogging before it's tested, every other intake in this test should get the same treatment. I'm not encouraging this action, but if it is the case that they get a second round dyno session, with out the same situation for every other manufacturer, then I feel their final dyno results should be left out of this dyno challege.

 

I agree on this as well.
There should be no favoritism one way or the other.

If you are going to test intakes - do it from stock. Reset the ECU, run the dyno on the stock. Then install an intake drive around for 30 minutes - 60 minutes then dyno and repeat with one more intake that day.

Do the same the next day Hopefully the weather and overall setup will be similar so this test will work fine

 

LOL... just please, this isnt a real intake... its a good lookin- soundin carbon fiber box... lets leave it at that.

 

If you have no interest in a genuine discussion of why the intake didn't produce power then don't post.
Little quips like this are immature and worse unwelcomed. You have a genuine question? Ask it.

 

yes, constructive criticism please
