And the winner is... tie?

I went to Sound Performance in Bloomingdale, IL today for a dyno run of both intakes on my 5AT G35 Coupe.



First was the Stillen intake/Z-tube (short ram), the result was 238 WHP.


After the 2 runs, the guys at SP were nice enough to let me use some space in their shop to swap my intakes.



Now, the AEM... 238 WHP?????


Yep, as you can see, there are no difference between the two intakes. So whichever you choose to go with, you should get good results.



A couple of notes on today's test...

* The Stillen intake is brand new and the AEM has a new filter (the new dry synthetic version - which is supposed to be better then regular filters)

* This is the reslut of a 5AT. The 6MT, may get higher results.

* Because I had a 5AT, there was no way I could get an accurate torque specs (hence why the dyno graphs do not show torque) But it is my belief that the torque difference between the Stillen and AEM will be little if any.

*My 5AT also had the following breather mods equiped: Stillen cat-back exhaust, Crawford high-flow cats and Crawford plenum.

So there you have it... cold air or short ram makes no difference when it comes to dyno measured power. However, I should mention this: When I was driving to SP on the expressway I had the Stillen equiped. On the way back, the AEM. The Stillen intake had a slightly better response then the AEM.

Thanks again to Mike, Jerry, and the rest of the guys at Sound Performance for their help!!

That's strange, you would think that when you were on the road, the cold air setup would have gotten the thumbs up.

Either way thanks for the info!

yeah but what about just plain idling...
ram airs sucks in hot air from the engine bay if no wind is blowing...
but at speed it should all even out...

 

Having a AT5 shouldnt make any difference in getting a trq. reading on the dyno . I dyno on a Mustang dyno and never had a problem.

Thanks for taking the time to do a comparo !!!!
