For $80 you can build your own intake.

No, of course Cleveland and I aren't thermal engineers, but we tend to believe the GM Powertrain Engineers know more about designing an efficient air intake than amatuer "modders". While you're in there, maybe you should shade tree up a design to improve on GM's Direct Injection, too!

Look, all you would have to do is build a heat shield around the filter and you would be fine. There is a lot of air circulating around this area. You can look straight down to the road from the engine bay in this area. If the turbo sat in front it would be a different story but the "hot turbo" is in the back. Why do you think Chevrolet put the computer here? Not because it was hot. Computers don't like heat.

And stop sterotyping..........Unless you are one of those hairy knuckle, gold chain wearing, Trans Am drivers like me. .

my thoughts are to get a free flowing intake, not necessarily a CAI. i'm thinking i will be going with an S-Max intercooler at some point, which they put a couple fittings on their ICs that attach to a line running through the inside, for you to run CO2 or something through, to really chill the boosted air inside, after it goes through the hot turbo, and there's not much let to heat it up from there. you want cold air getting in the engine, there ya go. it doesn't matter how cold it is once it gets to the turbo. okay, well, it does, to a point, colder before means it won't heat up as much, but still ambient temperature differences won't make that big of a difference in the end, at leat not near the difference this setup would make.

Oh stop it. How am I supposed to help it when I see people enouraging others to dismantle some OE component or system in favor of something less optimal? I can't help but speak up.

But you're right in a sense: its their car, they are free to mod as desired, even if it is apparent that the mod in question may be a step backward instead of forward.

I believe the Ford Lightning has some type of AC route for a quick boost, any ways I think the stock air box could stand to be improved and let a bigger better IC do the job of keeping things cool.

Actually I am an engineer. Focusing in thermodynamic AKA Chemical Engineering.
Now what??

More over I was an engineering intern at GM about 8-10 years ago??? I'll pause while you take your foot out of your mouth. :) "That-Guy"

LOL, I always wanted to post in huge font....

Thanks for the kennybell link whiteheat.......

I made one of these hot air intakes for my 2000 s-10 , it lies in a landfill somwhere now.

If your talking about a CAI, freer flowing then stock, and cheaper than an exhaust, or tune, then were all listening.

All hail Clevelandhhrss, who's impressive resume as a thermodynamical engineer makes him an expert in engine intakes. Not to mention his intern ship of bringing coffee to all the important engineers who's stock engine intake designs could never be improved upon....WHAAAAAAATTTTTT NNNNOOOOOWWWWWWW??!!

Hmmmm: "intern 8-10 years ago" Lets see where were we 8-10 years ago. DI wasn't even a thought, Chevrolet didn't have a turbo vehicle in their line up, and variable valve timing was considered exotic. I am sure you have kept up with the times being that you WHERE an intern. If you were a REAL thermodynamic engineer you understand what I said by the intake box sitting on the engine. Have you ever felt the heat coming off our engine? Also if there are any bean counters out there, heaven forbid I say this, but sometimes engineering takes a back seat to cost. It was probably cheaper to do this than route the intake in front of the computer, did ya ever this about this? Yes manufactures will cut costs anywhere they can.

Also, look at Chevrolet’s crossfire injection in the '80's, your telling me the factory did it right? How many of those cars were switched to carbs. If the factory did it perfect every time then why is the aftermarket selling billions of dollars in parts every year and why is GM selling aftermarket intake kits? I guess GM is rice now.

You are correct I delivered a lot of "HOT COFFEE". I know my way around a copier too. I think my hands might still be blue from the prints :)
