Any of you that are familiar with the M5 may know about the IN500 intake. Basically it works like this: two 4" holes are cut in the lower front grill of the M5, and a tube is run on each side to the intake boxes. The M5 gets 30 HP from this. If course, it only works at highway speeds. So my buddy and I decide to do it to his M5 last night, and it worked great. We used 4" dryer tube, and PVC drains painted black as the flange.

So I said why the hell can’t I do that?

So today, I did it. I popped off the intake box, the bumper, and the massively oversized resonator. God that thing was huge. I couldn’t believe that my engine breaths through that tiny-ass little tube...

I cut a 3" hole in the driver’s side place on the bumper where the fog lights would go on the new TL's. Using a 3" black painted PVC drain with the grill of the drain cut out. 4" dryer tube adapted to fit the 3" flange. I ran the dryer tube to the 3" hole where the resonator used to connect to the air box.

So I took it out for a little test drive, and I'm impressed. Up till about 45-50 MPH obviously there was no improvement, but after that, my TL-P had a very noticeable difference in performance. When ever I’m moving faster than 45, I can hear it eat the air its being forced. It’s nice and deep!!

At 80 MPH, i can drop it in to 3rd gear and then i really see the difference. It takes alot less time now to get to 110 MPH

I already ordered the K&N air filter so I can get that much more air, as I’m sure the stock filter is causing a little air restriction.

So what do you guys think? I’m surprised no one ever did this before. I did have to cut the corner of the frame a little so the tube could line up properly, but nothing big. In the end it was real easy.

Total cost: $10.56

Nice.

pics please

 

coming soon, i have to borrow my buddy's digital cam.

 

Sounds good, try to get us some pictures! Also, will someone teach me why these systems don't injest alot of water during heavy rainstorms? They must not or the factory wouldn't use them. I'm guessing not much water makes it in there. I don't mean submerged in water.

 

id be afraid of water too...



@cUr@-TL

 

Actually it will kinda work itself out in the end. If you know what dryer tubing looks like, you know that it’s comprised of a metal spiral lined with metallic plastic. There’s only 2 ways water hits the lower part of your bumper. Driving through a puddle, and a damn deep one at that, and rain.

A little bit of water is ok. Even if I dumped a glass of water in the hole, it would still have to travel 2 feet to the air filter, completely soak the air filter, and lock my motor. Even if the water gets to the air filter, most of it would vaporize and explode when it hits the combustion chamber. If an OUNCE got through the air filter, well, that would suck. But I can’t see how that would be possible.

The great thing is that because the OE air box is still there. With a CAI, the filter is 5 inches from the splash guards. The stock filter is 2 feet. You get hydralock from a CAI because the filter gets submerged, which is not possible in this case. Hell, even if I stuck a frickin garden hose in the new hole of my bumper, I bet I could pull the filter and it will still be dry.

Only bad thing is that I will now have to check and clean the air filter much more often, as now more dust/dirt/bugs and other crap will get sucked up more easily...

well that if you have stock intake..but most of us have CAI and air is being sucked at the bottom thus giving the same effect with much cleaner look...of course, ain't $10 though

 

Actually, a CAI works alot differently, and the effect is different too. The good thing about my system is that at highway speeds i get a greater increase in performance, but no increase at slower speeds. a CAI gives you an increase through the entire curve, but not as much as a forced induction intake like mine. IMO i think my system is safer than CAI too... And as for the look, you cant tell its there unless you look for it. Im putting some mesh on the front sometime this week i think, then you will never know its there...

**** you mother****er random****in'walker ****in' racist bastard

 

what the hell is this? why so mad....?

 

saggy diaper that leaked

 

What the F*ck is wrong with this dude? This f*cker needs to be banned and his ass needs to be sticked on top of a flag pole.!!!

 

woah mental picture....*flag pole* hahaha

 

*in italian accent* ah take it easy......

 

you know why.... 'cuase you cussed out all asians in a thread that was removed from this site.... why don't you tell everyone in here what you said?

Well, if everyone wants to know, randomwalk101 was mockin' ASIANS..... and got flamed hard in a post, which was recently removed....

 

Let's try not to bleed one thread into another... and put down that emotional baggage, man.

 

It was removed for a reason....so let it die...if you don't care for him than don't read his posts or choose the ignore option for him. No more posts like that again.

 

I had the resonator removed (the ugly airbox behind the bumper), and the Comptech Air Filter Element. It's got a deeper sound, as opposed to the CAI, which is a loud shriek at WOT. IMHO, it sounds a lot better combined to a nice exhaust.

hey buddy,
ever try compressing water? nope, it can not be done. so imagine if you got just a little bit of water in your engine and your piston tries to "compress" it - i can assure you that it will not just vaporize. certain companies offer bypass valves for their CAI b/c of the risk of blowing your engine if water were to get into it. and jesus, why would your friend be tinkering with an M5? that is one fine specimen that the weekend mechanic should not be tinkering with.

 

Your right. But an engine can handle a very small amount of moisture without screwing itself over. At least, thats what people here have told me, and what ive read.

As for the M5, that upgrade is an actual product avaliable. its $1000 and looks a little nicer than what we did, but it works. And its not like the M5 is some special super secret beast of nature. Its still a motor, and the laws still apply.

http://www.bmwm5.com/vbulletin/showt...threadid=20626

for an example of the IN500 intake.

 

Motors can handle a small amount of moisture. There used to be water injection systems at one time that reduced pinging and knock by in injecting (or misting) water into the intake. Problem comes in when there's not enough air (vs water) in the cylinder to compress & cylinder pressure increases.

I agree that on a roll, probably not enough water will reach the cylinders to do any damage. If you submerge the opening, you will definitely suck water in like a straw.

 

Agreed,
like i said, if i let that hole get submerged (i would have to go in to a puddle about a foot deep) then its my own damn fault

 

pics!!!!

 

YEAH!!!

 

Guyz,
Just installed the K&N air filter tonight... Wow, that made it even better... Now the car totally has noticeable pull through the entire curve... You 99ers know that if your right at 60 mph, and you floor it, she drops to 2nd gear and "kinda" accelerates... its a dead zone in our cars... now it pulls like it should... PICS COMING SOON GUYZ!!!!!

 

whens soon im so like ready to ship over my digi cam to you...sike
hurry please...

 

Just when you need a pic of "This thread is meaningless without pics" to use, you can't find it anywhere

Tatewaki

 

where can I get a dryer tube?

 

Home Depot

PS still no pics, it still looks like ****, ill get there eventually guys....

 

Get some pics. I'm serious about doing this mod and I'm not exactly sure how.

 

get the Icebox From Comptech.
