Two questions, one is something I already did, the second is an idea I have...

I have a MHP CAI on my 2000 Elantra and I took off the plasic covers that cover the holes for the fog lights so that I could get a more direct airflow into the fenderwell. Is this a bad idea because of all the road gunk that can now be thrown directly into the air filter?

Now for my idea... the object of a CAI is to pull in more air, as well as cooler air. Well, I was thinking if you could rig something up to spray a mist of water onto your air filter as you were driving, would this not cool down the air a lot more and give better performance? Has anyone tried something like this?

OK, and now I just saw a post about something that is similar to my idea... except they thought of it a long time before me, like almost 10 years before I was born.

Same idea, right?

 

you dont want any of that water to get into your engine or your ****ed i say its a bad idea. if you want to do something just for a short race or drag pack ice all around your intake pipe and manifold thats what i do.

 

I've had the idea to run CO2 line to intake filter and shoot it when you want to cool it down...how bad would this be on your engine

original idea was for intercooler since a lot of people like to cool down their ICs with a spray from the ol NOS bottle just before a pass. just a random thought floating through my crazy dome.

 

Spraying a FINE mist of water on the filter SOUNDS like a good idea....execpt that the typical K&N Style filter uses OIL to trap dirt particles.

What happens when you try to mix Oil and Water? Anyone?

Also, most K&N Style filters use cotton gauze as the filter medium. Cotton, since it is organic, will deteroriate if it is wet. Say goodbuy any useful filtration if you lose the cotton gauzing.

Spraying a miniscule ammount of water in an ultra fine mist into a CAI AFTER the Filter and AFTER the MAF, might do some good, but there's a problem here.

The MAF doesn't like water. Trust me on this one. Don't ask me how I know.

For the Tibbies air intake system to read the proper amount of air, the air temp sensor needs to be BEFORE the MAF. Since you have to spray water AFTER the MAF, the computer does not see the decrease in air temp, and the increase in air density. Thusly...you run lean.

Class? What happens when you run lean? BAD THINGS! (Very Good!)

If you had a MAP equipped motor, that would work, as you have no MAF sensor to get screwed up by the water spray. But with a MAF system, there is just no way to get it to work unless you want to resort to ECU trickery (S-AFC).

With water Injection AFTER THE MAF, and a S-AFC, you MIGHT see some gains, but since you only gain about 1 HP for every 10 degrees in temp drop, you would have to drop the air temp 30 or so degrees for you to even SEE a gain on a dyno. Dropping 70 degree air to 40 degrees with just water injection is NOT GOING TO HAPPEN (unless you inject icewater!).

To sum it all up, it's not worth it on a basically stock motor. Bump up your compresison to 13:1 or higher, and you could use the anti-detonation properties of the water injection...but for a stock motor, it's just not worth it.

 

Yeah, I didn't think the water would be a problem... you drive through mist and rain all the time, your engine would be ok even at this level even without the AEM bypass valve (which I DO have installed) because all the water would evaporate before it gets to the point where it would be bad for your engine. But I suppose I understand why it would not gain you much HP.

It just seems like my car is a lot faster when it is cool and wet outside! That's where I got the idea... but I guess that idea's a bomb...

Anyway, Random... what about my first question, about the air filter being exposed in the fender well with my fog light cover off?
