You might be right, but given that it is recommended that you disconnect the battery and you need to unplug the ECU in order to fit the ALTA intake (and presumably the others) I don't think NOT resetting the ECU is an option as it will get reset by default in the installation process.

Also if the ECU is reset each time, while it may not be perfect, at least it will be consistent.

Likewise with the bonnet up or down. I've not done it but a friend of mine has tested his MCS on a dyno with bonnet up and down and in that instance there were no noticeable differences in the results.

I guess people should be aware that a dyno can never perfectly recreate on road wind effects and the like and should accept dyno results in that context. Equally, having the bonnet up or down is a moot point IMO, so long as the same procedure is followed exactly for each test. Removal of the variables is always one of the biggest problems faced in tests such as this. Which is why I think using the stock filter as a control test and then retesting when possible to determine ongoing accuracy will always aid credibility when the knockers start pulling somebody's hard work to pieces.

 

Even better yet, and cheaper, is do some serious data-logging, coupled with a few G-Tech readings. While the G-Tech might not be accurate as many would like, it seems that results are quite repeatable/consistent; and that's what's most important. Nothing like data from real driving to draw conclusions. Get strip times!

An open bonnet changes things much, especially when trying to determine the effectiveness of something like an IC. All intakes will benefit from cooler ambient air from an open bonnet. The AGS might even benefit the least as it seems to get decent ambient flow from the front of the car....

I love the quest though! Isn't time, or so many miles needed for the ECU to adapt to such changes? Maybe a battery disco will suffice... I don't remember... Also, with many intakes now wanting to be evaluated, adequate cool-down time should happen, and it should of course be done equally...

I'd say get the Beta BiM-COM, borrow a G-Tech Pro (I was lent one for 2 weeks), and put the car through some real-world testing. Just my thoughts...

 

one last tip: monitor the intake temp, before and after each run and try and start each run at the same (hopefully low, like 130 deg F) intake temp. Leave the fan running on the motor after you shut down to aid cooling. bring beer.

 

The voice of reason.....Oh yes, and have fun....isn't that what these cars are all about

 

One thing you might consider doing to keep the cool-down periods between intakes consistent is to prep the car for the AGS install before the first dyno run. Get the car in service mode before you begin. There may be limitations as to how much you can accomplish in this regard, but this may help in keeping the intake temps consistent (Thanks JLM!) across the intakes being compared.

Additionally, I wonder if three pulls each across three intakes (instead of two pulls each across four intakes) might not be a better idea. The additional pull on each might provide more reliable numbers since you would have a tie-breaker to help in identifying anomalies and for averaging. You would also spend more time on the dyno and less time wrenching.

 

just sent my 10 bucks! i can't wait for this, thanks for this msfitoy and JS and everyone who got invloved. all the options i've been weighing for my new intake are involved (Pilo, Alta, and AGS) "let's make this a good, clean fight-let's GET IT ON!"

 

lol dude!!! DONT CANCEL!!! All you have to do is upgrade to premier..its FREE!!!! And all it does is talke 3% if you were paid via Credit Card.

 

It takes 3% for all transaction whether it's paid by credit or direct bank transfer... which is why i moved back to my basic plan.

 

eMINI brings up a good point, but I don't know how much prepping you can do for the AGS, due to the difference in location of the supercharger tube, TB mounting position, radiator hose re-locaton, etc. That intake install is quite an undertaking. So it is probably best to hook up the AGS once all the testing for the other intakes is complete. Believe me, once you go throught the process of installing the AGS, the last the you'll want to do is take it all apart to install another intake. Also, you guys are gonna need some serious cool down time before installing the AGS unless you enjoy the aroma of seared flesh. This will no doubt take you all day, if not all night, to complete. best of luck!

 

Quite right...IF we're lucky to have the dyno all to ourselves, IF we don't run into changing weather conditions, IF I manage to install/remove all intake without a hitch, IF JS's Mini doesn't boil over from so many runs...you guys get the picture? This is a compromise at best

 

this has got to be the best thread ever for the AGS system

have you set a date as yet on to which this is happening ?

 

Sid and all interested,
Just talked with person at the Dyno shop. The tech is out for the day and probably tomorrow. I'm to call back Monday to see what arrangement can be made. His girlfriend is hospitalized. Cost is; first hour, $100.00 and each additional hour $70.00. We'll have to remove car to do filter swaps, unless nothing is scheduled for the same day. My best guess is we will use at least 2 hours of Dyno time for runs and repeat set-ups. After I set up a test time; to Sid's schedule, mine and the Dyno's, I'll post the test time in this thread. I see everyone is as anxious as I'm to see the results. And again "THANKS" everyone.
JS

 

Logging the upstream air pressure (as it goes into the supercharger) will be very easy to do accurately for each of the runs. It will clearly show the differences in performance between each of the intakes especially since the tests are being done on the same car, same day, same conditions, etc.

 

Looks like we'll need every one who expressed commitment to step up. So far we have 17 people who have contributed $10 each...just enough. We could use every remainding expressed doners' fund for "incase" we go over time. Take that back...I bet we'll go over time.

Remember, I'll be removing the stock system, installing Pilo, removing Pilo, installing Alta, removing Alta, installing AGS, and cool down time inbetween runs, data collection, looking for missing dropped bolts, bathroom breaks, swearing breaks...The math tells me that we'll well into three maybe four hours

 

I have another $10 if you need it

 

LOL...Thanks Bob but let's wait for the other's who haven't paid to fill in first

 

thats a pity would love to see what gains the WI makes

 

I installed the WI primarily to cool the charge. If it makes a few ponies...then bonus

 

I'm in for $10 if you re-post your PayPal account again so I don't have to read this whole thread again. :smile:

This is the most ridiculous post I ever saw . Paid some one to get a piece of paper, plus the figure isn't from your car, and you never know if the data is fake or not. I really feel pitty for those who already paid and need to keep the best every secret. Anyway I really think this sounds like a scam, can some one lock this thread and suspend the poster? This an unfair deal and I bet there will be more possible victim.

If you really respect to other NAM members, you won't ask for people in here to paid for your or your friend's dyno.
If you are truly respect to this board, why not disclose the dyno result but making money to paid for your or your friend's dyno?

 

You obviously don't know who I am Thanks to guys like you, the people who are supporting this effort would be less inclined to publish the data when they receive it. Thanks for your thoughtful input and PLEASE do go tell DiD all about this "scam", eh?

 

wow what a nerve posting that crap,
you need to go back and read this thread from the beginning, and also understand what this subject is all about before you jump in guns blazing, making a total *** of yourself.

 

As the wise sergeant said in Stripes, "Lighten up, Francis."

This is the NAM community at work. Some are donating time, some are donating money, some are just watching. YOU can believe that long time members are up to no good - the majority of us will appreciate their efforts and the info that comes from them.

 

LOL - whateve dude....

 

i think i spoke to soon...theres always one!!

i dont have many posts but i certainly know the good people from the bad....and im 110% happy for MSFITOY to have my $10....good value
