MDesign vs AirAid on the DYNO!

EcoPowerParts · February 03, 2015, 09:47:01 PM

To be honest, dyno is not best way to test an air intake, the track is. MPH will show you true HP gains/losses.
I'm not discounting your findings, just know that I saw a loss of .2 and 2MPH with the airaid at the track compared to stock intake, I switched back and forth twice in one night and replicated my testing on both switches.

So what are OEMs using to test their vehicles' outputs? Surely they are either using computer modeling or dyno runs most of the time, and track only a relatively small % of the time? $ & sense and all that.

Has anyone performed a stock intake vs MDesign test?

Everything is engine rated, not WHP rated.

True, but don't they need to know drivetrain losses, even if they don't release the numbers officially?

Interesting results. Yeah, numbers are close enough to say they are both equal. Someone posted volume of air, makes me wondering if the extra intake tube I installed helps. I do notice more pull at the track about 1/8 miles, not sure how it will work being dynoed, unless they have a real big barn fan.

No, people like you and I come up with guestimated WHP. The manufacturers use engine dynos.

Gotcha, thanks!

Thought I'd chime in about something that was brought up now that the discussion has been started.

First off I'd like to thank the community for all the help thus far in testing out the intakes, without a great community most of this would not be possible.

Now to to the data...BigMoneyCloser had done the initial dyno using a Mustang dyno and back to back there was a significant gain with the MDesign over the Air Raid (10.6whp & 16wtq) though as we can see in this test the MDesign and Air Raid were pretty close. The only difference between the mods of both peppelepugh and BigMoneyCloser are the addition of downpipes and catback exhaust.

The intake is a breather mod, along with anything that involves changing the intake/exhaust systems. As such, the combination of other intake/exhaust modifications can have a affect on how well the added performance parts compliment each other as a whole which is what had occurred in BigMoneyCloser's testing. With the downpipes and catback installed, being the only difference as both vehicles have 3Bar tune and intake, the same tests showed a gain when swapping the Air Raid for the MDesign. As suggested above, the best method of testing the intakes for "quickness" or speed would be at the track which I plan to do when the weather/tracks open up here in Michigan.

We're all looking for ceteris paribus data

So wouldn't a higher demanding car show the differences between the intakes if there were any?

I don't understand your rational.

Again OP did an outstanding job collecting the data from the runs to see what the car was doing and what effects the intakes made on the incoming air into the throttle body and all the processes prior.

The 'higher demanding' car did show larger discrepancy in favor of MDesign.

While only a small gain here, the larger gains seen on the previous dyno results could be explained by the symbiotic relationship the other (exhaust) mods have.

91hybrid · February 04, 2015, 07:57:53 PM

Got it. Big's xsport has the same setup as OP's plus Catted down pipes and exhaust.had it flipped. Carry on.

Debonair70 · February 06, 2015, 11:02:25 AM

Definitely a great read. I'm still running the stock air box with a drop in K&N filter. More than likely I'll make my move to the MDesign....THAT DESIGN DOE!!!

after watching mustang cobra n gt guys drop all kinds of crazy $$ on the latest and greatest cai i just stuck with the basic ebay in take for my mustang gt 4.6 2v bak in the day (mostly for looks ) and never had any issues...once any engine gets heat soaked if ur not blowing 45 deg air down it's throat ur basically pissing up a rope...
