Heat sheilding for intakes

[P10DET]

I hate to rain on your parades guys, but you are not getting ram-air. To truly get ram-air, you have to generate positive pressure. In other words, you have to build pressure faster than the engine can suck the air away. There are few places this is really possible. The base of the windshield is one (very) high pressure.

Simply installing a scoop will not do it. Facing a venturi forward on the car will not do it. You would need to get a snorkle high enough to be above the boundry layer of the airflow. Running hoses up to the filter will definitely not do it.

Your best bet is a CAI. I don't think you'll be able to measure any gain from a ceramic coating on the CAI, but I've been wrong before. The airflow is so fast through the piping that it won't transfer much heat IMHO.

Hey Redvalkyrie, I dug up that old article from Sport Compact Car on the SE-R. It was an article entitled "Cold Air Without the Cold Water". The purpose was to get colder air withou having to use a CAI system.
They just used a piece of $10 aluminum sheeting to create a barrier to isolate thier intake filter from the rest of the engine compartment. Nothing fancy. It appears the hardest part was trimming it to meet the hood nicely when the hood is closed to keep a good seal.
They tested their intake temps at the throttle body and measured a drop in temp of 20 degrees at idle to an average of 7-8 degrees at cruising. Not too bad for $10.

Yeah, but what was the hp increase?

[aluke000]

They didn't include any HP measurements in the article. But with 10 degree drop in intake air temp at the thottle body, it can only bear a positive benefit. And at a cost of $10 in materials, it is at least something to bear in mind when others are shelling out $$$$ for other fancy systems.

There are many members of this forum who do not have the excess funds to spend max $$$ for the most HP like a DET engine, but many are interested in inexpensive ways to improve their vehicles.

If this little $10 mod produces zero improvement in HP but allows the engine to breather cooler air, that may not be of interest to you but may be to others concerned about how their engine breathes.

This thread was started to discuss air temp anyway, not HP gains.

Very true! And sometimes a little advantage is all you need.

Easy bud. I'm not looking down on anyone.

I just don't want anyone to think that they can get anywhere near the improvement in hp from this mod that they can from a CAI. Lot's of folks do think that. Also, some folks are talking about spending a lot of money to lower the air temps (ceramic coating a CAI). This helps, but folks should be aware of the potential gains to evaluate against the cost. If I came across wrong, please accept my apology. I'm only trying to look out for folks

But, you are right to remind me that not everyone wants to spend a lot of money on their car. In groups like this and others where there are a lot of folks spending a lot of money, it's easy to forget.

Regardless of why it started, remember that threads are just that, threads. They sometimes take on additional topics as did this one. HP has been discussed in relation to this thread, so I didn't bring it up. Fair enough?

Hey no problem, it's good we can come to a mutual understanding.

The Hotshot composite intake is intruiging. If time permits I will probably end up fabbing a custom intake that has all the characteristics I am looking for. Ah, it's time that is the valuable commodity...

[aluke000]

Oops, I meant Iceman intake, not Hotshot.

Anyone have one of these? I am curious how hot to the touch it gets when the engine has been run for a while?

[redvalkrie]

Thanks 4 diggin that up I was looking for the perticular mag I can't find it, But that is what I am trying to acomplish a cooler ambient around my filter + not getting engine dust & heat, not completly aliminating cause that would be inposible on a low budget fix.
I am trying to find alternitives to help out the people with limited funds once I get the mesurment's down & fixed up peurty I will let the 411 go on this forum & will share it with G-forces & boogie as alternatives to low budget fix-ups.

On the other hand I like the CAI thing, about the Iceman I will be digging through mag's to look for their addy, these intake dont get hot at all they get luke warn.

A friend runs one in hes ride well from SF to AZ phenix we drove stright with few rest stops of 15min & we were able to put our hand on the piping & it was warn not scorching hot like the rest of the engine bay also this intake is a cai type intake it goes into your fender & rests in the tire well. I wll keep searching for their site!

[redvalkrie]

One more thing Iceman it's an extension they sell that converts it to a CAI. Last time I saw the pricing they were at $229.00 for an intake with the extension they were limited in color to blue black yellow red white & purple. Well be searching tonight for mag!

[aluke000]

Red, I just may try something similar (along with all my other car and non-car projects I have on my plate) to see what the results would be. I'll keep you posted with any results if I do.
