Turbo Cold Air... what do you think?

[jimwross]

We just made a few of these... what do you all think? Any interest?

 

[clownface]

very nice i would like to have something like that.

 

[clownface]

Why is it you never see stuff like this for our cars??? all you ever see is replacements for the stock stuff or custom stuff someone did for there own car, why is it most vendors dont cary cold air intakes for us?????

 

[miteclgst]

The reason vendor's don't offer cold air intakes any Turbo Eclipse is because you would need to move the MAS or attempt to run piping through the fenderwell. This setup is real nice that jimwross built, but it requires a GM MAF and an MAFT. If you already have that stuff then i guess you would be free and clear.

Jimwross I like your design, it looks really professional with the mandrel bends and all, I was just wondering if you are at all worried water getting sucked in the filter during a good rainfall? I was going to mock up something for my 2G (more of something to direct the outside air from the side vent into the area where my injen intake sits) but I was kind of wary when it comes to sucking up water. Neways nice job on the setup, it's always good to see people designing and fabricating their own ideas.

 

[clownface]

yeah im worried about the water thing 2, lets get some more info out on that

 

[jimwross]

I'm not really worried about the water problem, its not just like a NA CAI, as long as it doesn't get completly submerged in water and trys to suck in, it should be fine.

Intake -> Turbo -> Engine

We've had a ghetto'er setup (same concept though) on a 1G for quite some time now with no ill effects...

 

[clownface]

what about like going through a big puddle really fast when your not paying attention or something? would that get it wet enough for it to suck in the water?

 

[miteclgst]

being that the filter itself is far enough in front of the front tire to not pose a threat to sucking in water if you hit a puddle at a high rate of speed, but a small divider behind the filter to section off the wheel well area from the filter area probably wouldn't be a bad idea, even if something was fabricated to divert the air from the bumper directly into the filter would probably help out, creating a sort of ram air effect. I would still be worried about even rain just getting sucked into that area, I mean think about it if you are boosting 15 psi that is some serious vacuum at that filter so any water or foreign object for that matter in around the area of the filter would probably be fair game. I wouldn't so much be worried about getting water in the engine, I would be more worried about water hitting the turbo when it is spinning at insane speeds. then again maybe the water would atomize or break up when it hit the filter, removing any danger of large water droplets hitting the turbo. THe only real CAI that I have seen on a turbo car besides this one would be on Dre's 2G GSX, if you look in his gallery you will see that he has his filter sitting in about the same spot as jimwross does. Maybe someone could PM him (dre99gsx i think) and ask him if he has ever seen any adverse side effects of the CAI setup that he built, maybe we are all worried for nothing...

 

[yo2001]

it might not take in alot of water at once but it'll collect in an IC and stuff eventually.

 

[jimwross]

I dont think it would collect in the intercooler... I also would tend to agree that if any water did get in, pretty much vaporize in the turbo. More so you can just think of a regular intake filter, if you get water in it, itll be fine, just dont over do it.

I guess just think of all of the people w/ NA engines who run CAI, puts it all in perspective... i mean thiers goes straight to the throttlebody... and you really don't hear much about hydrolock....

So just would practice the same warnings as a NA i guess... don't go through huge puddles etc...

 

[TSIfreek]

I wouldnt worry about any water probelms because heat will make it all evaporate but If you think about it it can give a cooling effect like water injection but it will most likely evaporate before hitting the innercooler who cares if it does anyway it cant hurt anything unless you put the nose of the car in a pond and leave it run :laugh:

 

[ClipseT96]

aem sells a water filter for their cai. Couldn't u just use that and not have to worry?

 

[entropy138]

Someone should take their K&N out and hook it up to your vacumn. Turn on vacumn and not how much air flows thru it (sound will do - precision isn't too necessary in this test)

Next soak you air filter in water for a minute - (think similar to following a car for 30 minutes on a soaked hwy) - now turn on the vacumn again and note the increased strain on the vacumn to suck air thru...

Now think of the way a turbo works and how this would affect you Spool up!!!!

Of course, a simple rain gaurd between the filter and the tire, and one in front of it will help minimize this.

guys, is a cold air intake really that necessary when having an intercooled engine. I understand underhood temps get pretty high, but those heat sheilds that seem to build a wall between the filter and the rest of the hood do a decent job. Again, i see no point with a cold air intake on our Intercooled cars. What if your intercooler is heat soaked? That cold air intake is now useless.

 

[Black95TSIawd]

just thought i should post again. My last post is not a flame at all but merely a thoughtfull statement. With that said, jimwross, you did a nice job of fabricating those pipes and i would hit them with a coat of high heat spray paint to give it that last lil touch.

We logged up to a 40 degree difference in intake temps bewteen the cold air and a standard intake pipe in the enigne bay. IMO that is a substantial difference.

You are correct inlet temps have no effect on charged air temps total power pre-ignition or timing advance :laugh:

 

[CanadianTSi]

Think about it...the colder the air is to begin with ther colder it will be when it enters the motor.

 

[dets]

i wouldn't worry about sucking water in the intake. I would just carry around a short ram intake in the trunk or somewhere just in case you get caught with your pants down in the rain.

Also, it doesn't have to be completely submerged. A quick dip in a puddle or something could do it also. I've seen it happen to someone else. An accord i think.

 

[44pirate]

My .02. Black top roads get pretty hot in the FL sun. I wonder if that close to the road might be hotter then higher up. I figure when your moving it would be cooler but idling at a stop would create hotter intake.

 

[clownface]

nah, i have a metal intake filter, once i drive for bit that thing will burn your hand if you touch it...the road prolly wouldnt make it that hot.

If you have a efficient intercooler it shouldn't matter where the filter is located.

really says who?

Intercooler efficiency has absolutely nothing to do with inlet temps and the reduction of total charged air temps recognized by lowering inlet temps to ambient. If the inlet temperature is lower the charged air temps will be lower.

 

[L2RTSiAWD]

This has been argued forever.

Show me some type of real data that proves it works better.

Show me back to back dyno runs.
Show me back to back timeslips.

How about you show me some *real data* that proves it makes no difference.

Fact:

Lower lnlet temps yields a more agressive timing advance across the board.

Fact:

Lower inlet temps reduces the onset of pre-ignition at any boost level.

Fact:

Lower inlet temps yields lower charged air temps post turbo and I/C
