xtremerevolution Posted June 25, 2007 Report Share Posted June 25, 2007 So I finally finished uploading my pics of my CAI, so I figured I'd show you all some pictures. For the pipe I used a 3" dryer vent from Home Depot. It's really ghetto, but its sealed pretty well as far as I could tell and its rather flexible. I used a few clamps with rubber connectors to mount the pipe to the TB and drilled a hole in another clamp for the intake temperature sensor. I forget which K&N filter I used, but it was $60 with a 3" hole. I started off by taking a dremel to my car and widening the hole that went into the fenderwell. I attempted one shot at a painted pipe, but that didn't work out very well so I replaced it. Either way, here's how the pipe fits through the hole. And the finished product: The filter is actually mounted right inside my front left bumper. Another bit of ghetto-ness. The filter is held up with a bungee cord that is attached to the center of the bumper. It's ghetto, but it works pretty darn well. Overall I was very pleased with the results, as I noticed a huge difference from the FWI I had before. I might need to cover it up a bit it once the weather starts getting bad so I don't start sucking up snow, but for now its sucking in cold air from right next to the road. I clean it every 10,000 miles, so it getting dirty too early isn't really an issue for me. So what do you all think? Quote Link to comment Share on other sites More sharing options...

Psych0matt Posted June 25, 2007 Report Share Posted June 25, 2007 could be a lot worse at any rate, if it works and is solid, +1 for you. doesn't look the greatest, but looks dont always mean speed (just look at the rice scene, totally backwards in most cases) Quote Link to comment Share on other sites More sharing options...
Q-Ball Posted June 25, 2007 Report Share Posted June 25, 2007 Price is right, just wondering about how it will hold up. But good work. Quote Link to comment Share on other sites More sharing options...

rockfangd Posted June 25, 2007 Report Share Posted June 25, 2007 i need to do something for my 3100 94 cutty. It has the k&N but it sucks in hot air instead of cold air Quote Link to comment Share on other sites More sharing options...
Grand Moff Joseph Posted June 25, 2007 Report Share Posted June 25, 2007 I give you props for the engineering effort. Nice thinking! Just two things: 1. What about a bypass valve for any water that is sucked up in there? Or does your design avoid that entirely? 2. Clean your engine! Quote Link to comment Share on other sites More sharing options...
Z34-5speed Posted June 25, 2007 Report Share Posted June 25, 2007 Noice!!! Very similar setup to the one on my Geo...(except mine is ram air), and i wouldn't worry too much about water, unless you stick the filter in a pool you should be a-ok.

xtremerevolution Posted June 25, 2007 Author Report Share Posted June 25, 2007 i need to do something for my 3100 94 cutty. It has the k&N but it sucks in hot air instead of cold air Yeah I had this next to the engine as a warm air intake (short ram for some of you) and decided after a while that recycling underhood heat as intake air wasn't a good idea. My engine temps dropped a lot ever since I relocated the filter. Price is right, just wondering about how it will hold up. But good work. The price is definitely right, and the dryer duct is decently solid so it will hold up for a while. I'm planning on replacing the duct with 3" intake piping some time in the future though, so this isn't a permanent job. Still, it nd doesn't rust or corrode, and keeps air sealed very well inside it. Not to mention, it weighs practically **nothing**. Clean your engine bay! Looks ghetto fab man, +1 for your resourceful-ness. Yeah I'm working on cleaning the engine bay. I'll clean it once I have the Cutlass Supreme Coupe rear wing and Z34 hood louvers installed. I'm sure you guys will want to see some pictures of that mod too, so I'll have the engine nice and clean for the underhood install pics. I give you props for the engineering effort. Nice thinking! Just two things: 1. What about a bypass valve for any water that is sucked up in there? Or does your design avoid that entirely? 2. Clean your engine! As far as I've read, you need to have that filter submerged in water for this to be an issue. It would have to suck up water clean through the filter (mind you the filter also sucks air around a 360 degree radius, not just from the bottom, and air is easier to suck in than water), and the water would have to travel up the ridged aluminum duct (like a river flowing upstream over rocks), all the way up into the throttle body, which is roughly 1.5 feet higher in elevation. I don't plan on crossing any rivers in the near future, so I doubt this will be much of a problem. If anything, the only problem I'll have is keeping the damned thing clean. Thanks for the feedback guys. This took a bit of thinking before I could put it together, but I didn't spend more than $20 + the filter overall. It was well worth it considering the impressive power gains I felt (not to mention the difference in the way the engine sounded). Quote Link to comment Share on other sites More sharing options...
1990lumina Posted June 25, 2007 Report Share Posted June 25, 2007 Is the pipe smooth inside or is it ribbed? Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted June 25, 2007 Report Share Posted June 25, 2007 I've thought about doing that for a long time, but since I already have a K&N I've been too cheap to want to buy another one for this Quote Link to comment Share on other sites More sharing options...
xtremerevolution Posted June 25, 2007 Author Report Share Posted June 25, 2007 Is the pipe smooth inside or is it ribbed? Its slightly ribbed in the areas that are more stretched out, since its a flexible duct. Does that hurt my airflow much? Quote Link to comment Share on other sites More sharing options...
synistershadows Posted June 25, 2007 Report Share Posted June 25, 2007 i was thinking about doing this same thign as well but i also have a K&N in and am too cheap plus i plan on dropping in the V8 later so it would be pointless for now Quote Link to comment Share on other sites More sharing options...
slick Posted June 25, 2007 Report Share Posted June 25, 2007 Yes, the ribbing DOES hurt some, but only to an extent. You may see colder air intake temperatures than metal tubing intake, which is good for performance(and not so good for gas mileage). If you do plan on redo-ing it, use plastic or PVC instead of metal, acts as a MUCH better insulator than metal does(although metal does looker better).

If you do plan on redo-ing it, use plastic or PVC instead of metal, acts as a MUCH better insulator than metal does(although metal does looker better). Ah ok. If anything, the ribs are pretty small, and only where the duct flexes. Where its a relatively straight pipe, the interior is virtually smooth. I'll have to see if I can find some thin 3" PVC to get the whole job done. As is though, this aluminum is a heck of a lot lighter anyway, so I might just end up insulating it instead so I keep it from getting punched with holes from vibrations against other parts of the car over time. That, and I'll have one hell of a time flexing some PVC pipe to get through the hole I made and out to the filter at the same angle. That's one of the main reasons I used this duct; its sealed well, its very light, and its very flexible. The original 3 foot length of duct expands to up to 8 feet; that's how flexible it is.

Euro Posted June 25, 2007 Report Share Posted June 25, 2007 not bad at all. Definitely not there for looks though!! But it gets the job done. Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted June 26, 2007 Report Share Posted June 26, 2007 I would wrap some sort of insulation around that tubing. Since it's metal, it's gonna heat up pretty good being right over the exhaust crossover area. Maybe hack up a cheap automotive sunshade for some reflective insulation(just an idea ).

I'm hoping to alleviate a great majority of this problem by installing my new Z34 hood louvers. You think I'll need more than that? Quote Link to comment Share on other sites More sharing options...

IRONDOG442 Posted June 28, 2007 Report Share Posted June 28, 2007 it depends on perspective...coming from a guy who owns a z-06 probably ridicule coming from a guy who has a z34 congratulate since he has both, i guess we will never know....

Darkness Posted June 28, 2007 Report Share Posted June 28, 2007 Damn, you guys are harsh! Whenever anyone asks for performance mods, CAI is always right at the top of the suggestions. That's what he did. Sure, it's not a billet tube with custom brackets and whatnot, but he didn't say it was for show. That steel duct has to flow better than accordian-style hose and at least he had the balls to try it out AND post it here. Quote Link to comment Share on other sites More sharing options...
