Hey guys, i was wondering if anyone else has done what i just did to my P5 today...I took off all my intake piping (the tubes and crap from behind the emblem/front grill) all the way up to the intake box....So now i get my hot air from a fat hole right below the intake filter...whcih is directly behind the radiators :P
Anyone else done it?
After a bit of driving, i've decided that it sounds quite a bit deeper and nicer, but it feels a little less responsive and stuff. It feels like it might rev a little faster, but its probably just psychological :P

What do u guys think?

(yes i know that hot air makes less power)

 

...do you really want to know what I think?

Seriously, go get yourself a proper intake or put the stock one back on. You are setting yourself up for a good 'ole flamin'

 

I don't think your modification is a good idea. First, for an explanation of how intake air teperature affects horsepower see http://www.protegeclub.com/forum/sho...+on+horsepower

Second, in an earlier post, PseudoRealityX explained how the intake piece just before the air box acts as a Helmholtz resonator which functions to increase low speed torque and aids acceleration off the line.

Unless you plan on going to an AEM or Injen intake it's probably better to stay with the stock intake system in terms of all around driveability. You might get a slight increase in performance by changing the oem panel filter to a K&N type but not having done this myself I can't really say.

You might be interested in how I modified my stock intake system. In an earlier post, Traveler explained how he cut away the horizontal grille piece underneath the inlet to the snorkel tube which sits over the radiator. This allows outside air at ambient temperature direct access to the inlet. In addition,at speed there may be a slight ram effect which acts to reduce negative pressure in the air intake system. Although the air inlet is now open to the outside it is still relatively protected so water ingestion should not be a problem.

I followed Travelers idea and performed his modification to my own car. As Traveler reported, I also found increased throttle response and a seeming ability of the engine to rev more freely while accelerating. In addition, I removed the MAF sensor screen which I believe also gave a slight performance boost. Finally, intake sound is more pronounced since the intake is more open now but nothing at all like an AEM or Injen system.

Traveler had gone on to say that he believes the major restriction is in the air box itself because of the obstructed path the air is forced to follow moving from filter to MAF.

I also have an AEM short ram that I have sometimes had on my car to compare it with my modified stock system. The AEM resolves the air box problem but also eliminates the Helmholtz resonator. The AEM definitely improves high rpm performance but the modified stock system gives better low speed perfomance and a feeling of more low speed torque. For all around driveability, I prefer the modified stock system.

Well, to me, the loss of power (if there even is any) is worth the super rumbly sound of the intake now :P
I was thinking of a way to make my own "CAI" using home depot tubes and stuff and maybe getting a K&N filter to put on the end, but i might just make a tube from the actual airbox that the panel filter is in down to near the ground...Dunno for sure how all of it will work so far yet tho.

HAI means ***** in Cantonese...

when i was first looking at your topic line i was all like...

 

LMAO!!!!!!!!

 

take off your air box and goto autozone and buy a 20 cone filter and put it on the Mass flow sensor. then tie it down so it won't bounce around... it getto, but if you can't afford a 50 dollar intake, then you have to stick with 20 bucks. i did it and its much better than the stock intake. reves smoother and alot better throddle responce.

 

Dude. Just do yourself a favor and go over to www.ebay.com and spend the $40 to get a real intake....

 

plus 10 for shipping

 

Eh, mine was like $42 after shipping.

 

Haha, initial22 :P
Yeah my original idea was like what Walight said, but when i did this, i was just messing around after i changed my oil and i had some time to kill so i took off all the extra plastic.
I'll probably end up making some piping so the air comes from down low, like a CAI but still using the stock air box and stuff :P
This will probably cost like $3 or $4 :P

 

And it will look like it cost $3 or $4.

 

Who cares, it's not like im going to be showing off whats under my hood with this car anyways..

 

just take the whole thing off, and run with no pipe on, then it will breath better.

 

good idea :P
i actually know a guy who ran his audi a4 1.8T with no intake or filter for a while....his turbo blew after like a week because some rock or something screwed it heh :P
