We did some dyno testing today with European Car Magazine. Mr 5 has already done some excellent filter testing so this was good info. Please see attached dyno sheet, I will post more tomorrow that give more comparisons.

It was very hot today which made comparisons to our baselines hard to compare. Also we made the mistake of running the car today with our big Show wheels and tires and not the same OEM wheels that were used on the baseline runs...my bad and we will have to re-run the tests with those wheels.

Also the vehicle had our new Eurobahn 135 exhaust system which is made up of a center section from the Turbos back into our muffler. This system makes about 10HP and 12Ft. Lbs of torque by itself.

So the aFe made about 10WHP by itself over the factory intake box. However if you factor in the change in wheel size and the extreme heat of the day I think its more likely that the intake made more like 15-20WHP. We will re-test in a day or two but I thought you guys might want to see this anyway. I can tell you the Butt Dyno says way more than what's n the paper!



Baseline 269.61hp 276.98 Trq.
Turbo Tuner 313.08hp 327.35 Trq.
aFe + Exst 332.36hp 335.80 Trq.

sweet!

cool, thanks for posting the numbers.. the torque figures dont really add up though.. unless the intake loss torque cause you said the exhaust added 12ft.lbs but there was only 8ft.lbs gained?

[Jeff@Eurobahn.us]

I think the wheels and tires made profound and unwanted issues for comparisons. We will re-run the whole dang thing. But we proved that the afe did make power. But by adding so much rubber to the car it caused a serious loss in torque and power.

Won't make that mistake again!

So do you think the aFe filter makes more than a regular dual cone intake?

[e90AW335i]

Once again this test is not conclusive in any way. You need to isolate the mods and add one at a time in order to make a comparison.

Do a dyno run with all the mods you have but with the stock airbox, than just change the intake to the AFE one and run it again.

When you add more than one mod at a time you can not make a decent or conclusive comparison.

great test and nice numbers

You are correct as usual mate. and we did do that. The problem is that we tested them all today with the big wheels and tires. So the comparisons to stock don't work correctly. Not to worry I will do it all over by the end of the week. I hate putting tires on and off its so dirty,,,,,

Damn, they made you get dirty Jeff? I will make sure to talk to those guys about that....

Just run a SSTT/Exhaust baseline with the same wheels and see the numbers and then just use the runs from the AFE you already have.

Thanks for putting in the work though Jeff!

[tom @ eas]

Looking forward to the new results, good hanging out with you at socaleuro on Sun.

+1, need the baseline to include the exhaust next time so we can see the real gains from the AFE

[ChaneRZ]

great numbers!

Hi Tom! Nice spending time with you too. You going this Sat. to Euro Crave?

seems like the AFE is making a considerable amount of horsepower!!

The way it looked to me is that the aFe makes a bit more power than the duel cones, not a huge amount but some. Where the aFe seems to really shine is not on a dyno with the hood up but on the road where the hot air under the hood is getting scavenged out from under the hood and replaced with cooler air. You need to have some speed on to get air up and unto the inlets in the grills.

The butt dyno really shows the difference,

I was really excited then I saw afe+exhst in small writing.... -_-

will wait for the isolated dyno...

[Panoz]

I guess you "Dynoed" the car with the hood open?

[Former_Boosted_IS]

Not so exciting huh? I think we will find just like many of us said, that these will not make more power than the standard dual cones.

[maui86]

can't wait for mine to come in!!!

Actually from the testing with the temperature gauge i am going to have to disagree with you. When you are driving the car there will be more power made with the aFe than with the dual cones. Between the velocity stack design of the inlet tubes which means more air velocity and the cross over connection which means that the air pressure is balanced to the turbos.

Thanks for the testing Jeff!
I definitely agree with the butt dyno and I agree with the results.

Another member did the testing as well with the hood closed and found some gains.
I personally agree that this setup will show more gains than the dual cones under normal driving conditions since the air will not be mixing with the hot air from the engine.

The dual cones just never made sence to me since the air entering the snorkel gets mixed with the hot engine air before it enters into the engine.
I don't care how fast you are going. Both groups of air will mix.

I would love to see an intake shootout but I'm seriously getting a little sick of spending money on dynos.
Does anyone want to sponsor me for something like this?

Mr.5, here is my only concern. You are putting these so called cold air intakes on top of the engine. Heat transfer via conduction and convection would be monsterous. I suspect you flow due to the snorkel may be negated by this heat transfer. The dual cones are off the side of the engine and mixing still occurs at speed since the snorkel is in place. The dynos are showing about the same gains already. I think you are seeing the location for the filters makes the cold air theory irrelevant.

Jeff, we have seen zero issues as to whether there is equal air getting to both turbos. Second, BMS already uses the velocity stack, so that advantage is negated. For $350, it would seem the money is better spent on traditional dual cones.

Just my opinion.
