Hey there guys. I've got a few questions for you. What's your preference, RAM or Cold Air?
My friend says cold air is not good at all for the car, due to the fact the it could suck up water and screw up the engine with one drop. He also says that he had a friend that had a pebble rip through his air filter and screw up the engine. Therefore he recommends RAM.
My uncle says to get cold air, because it gives more HP then RAM. He also says you could bypass the water with a bypass valve or something.
If I were to build my own Cold Air intake using tutorials from this very site, how much HP would it yield? How much HP would RAM yield? Which is better over all for my 88 Celica? Thanks for any help, and it's great to be on this site.

From my understanding, a CAI(cold air intake) is always better over a SRI(short ram intake). The SRI takes in the hot air from then engine bay, unless you mod you hood, and put a box in the engine bay to keep fresh air in there. A CAI usually sits somewhere around the front of the car's bumper, usually hangin out just beside the driver's side front wheel. It gets *cold* air into the engine, which I belive burns fuel more efficeintly than *hot* air. A CAI would only get hydrolocked if you drive thorugh massive puddles, and it acts like a giant straw, sucking water up into the intake, and then the engine which = hydrolock, and a fucked car. They do make bypass valves for CAI's, which I think work like this. Once they get so wet, the *block* the CAI from takin air from the main filter, and the engine gets air from the second source, which is usually somewhere right around the bypass valve.
I'd go w/ a CAI and a bypass valve, as I feel they would produce more HP than a SRI. It's only like 10 or less HP though, and it don't do much good without a exhaust to help the car breath.
Once again, if I'm not correct, feel free to correct me, but that's how I think it all works.

Okay, READ THIS:
1. There is not a single bolt-on modification that can add horsepower.. all it does is free up power that the engine already has
2. A short ram isn't really a ram at all. In fact, there has never been a true ram-air setup in existence. If you really care to know why, I'll explain it later.
3. The best setup cannot be a CAI, since each 90* bend cuts down on flow by (if I rememer right) 30%. 30%!!! on a typica CAI, you have AT LEAST 2 90* bends. Do the math.
4. A "short ram" intake is pulling air from inside the engine, but flows easier.. so.. what to do?
5. Build a short-ram intake system, and build a cold air box around it. If you want to, rig something up to direct air to this box from outside. This has been proven to be the absolute best setup. Is it more work? yes. Is it worth it? that's up to you.
I'm sooooo tired of seeing "how much hp will this intake give me". it won't. and if it does, it's minimal. the most noticeable thing you'll see is an increase in gas mileage.

There has been some debate on whether or not an intake is a noticeable gain in power. |

Cold air usually does help your engine, mostly because hot air sucks for combustion. On 3000GT's, everyone used to put short rams on the intake, but they found that the horsepower actually dropped. You could actually get that horsepower back, and more, by leaving your hood slightly open.
There is a happy medium somewhere between building a short ram that sucks hot air from the engine bay, and a 7 foot cold air intake that winds all over hell. What you want, is the coldest air possible, withthe fewest number of bends and restrictions. You can achieve the same effect by fully ventilating your engine compartment and using a short ram.
My advice would be to buy a cheap remote temperature probe, hang it in various locations and drive around.

Less. it takes 5 to be noticeable. There has been some debate on whether or not an intake is a noticeable gain in power. I had a noticeable gain in power with my upgrade to a cone filter and removal of stock airbox. I also noticed a lagging when the car had been running for over 20 mins. and/or on a hotter day. Solution: Scoop directing air to the intake hose, heat shield around intake. It doesn't lag anymore once it is warmer. |

 I did this CAI ~ turbotrdcelica.proboards29.com/index.cgi?board=howtos&action=display&thread=1099538541The wheel well method is in the right direction ~ how you do your tubing makes a big difference. I went through all that short ram intake ~ No matter what I still sucked in header air. Short Ram sucks. If anyone who as perfected the short ram air is schmooot.  Though I havent see how he does it under the hood ~ he says his short ram works too. If you can perfect the method of CAI in the wheel well.. you will get noticeable gains. I have it and I love it. |

I have a short ram and noticed a minimal increase in power, but driving down the highway while raining or even barely going through a dip with water standing in it my car gets water in the filter and starts to sound like a harley davidson  |

Its amazing to see a 3rd generation go from Frankinstien to Sleeping Bueaty. Figure of speech. U got picture of your short ram? |

Sorry ~ I havent seen schmoot in a while. I only remember him saying it works like back last year October posts. Sorry no, its functional but not as an intake system. It routes air directly onto my intake 'hose'. So when I'm moving I'm getting cold (depending on the temp outside I guess) air keeping my hose cool so the intake air doesn't have to run through a warm hose before hitting the throttle body. Lemme see if I have a pic of the inside  and my heat shield around the cone  |

if you are all about functionality instead of looks then wrap the intake piping in aluminum foil or header wrap.

Joel, I was taking a look at what you made, and it doesn't look like it would be sucking in cold air, but air actually circulating around the hood. If you could clarify this, that would be great.
Also, the tutorial written by Jeremy that shows how to build a CAI - does the CAI actually work and increase performance or no?
