this pic is what was done down at the mini meet this month
Attachment 31887


and once I got home I went a little farther and so far from the road tests it stays alot cooler in there now :D

I left a spot non taped as to be able to open the lid if need be
Attachment 31890
Attachment 31891

Its completely enclosed for now and I added a little redneck cold air hose to help it stay cool
Attachment 31892
Attachment 31893


the hose runs up right behind the light just to give it a little extra air sometime in the future im going to build a rigid box but for now this seems to work..
what do you think? :roll:

Danthurs 04-30-2008 04:42 PM

That looks nice. Very close to how mines set up.

putertopia 04-30-2008 05:08 PM

Looks good. Gotta ask... I see the insulation everywhere, is that something thats available at Lowes or the typical home hardware store?

Also, what stops any water from going in that intake tube under the bumper? Not that it'd be enough to affect operation of the vehicle, but if you hit a big enough puddle....

I'm thinking of extending a hose from my airbox just so it has some cool air to breathe. FWI isn't in the budget...

tpulliam79 04-30-2008 05:23 PM

the insulation is reflectix from the depot with aluminum tape covering it, the tube isnt attatched to my box it just helps to get colder air into that area :D

putertopia 04-30-2008 05:29 PM

Ah good deal. Thanks.

willwren 04-30-2008 05:37 PM

That tubing underneath looks strangely familiar. ;)

Glad it got put back to good use. It served Zilla well. :D

tpulliam79 04-30-2008 06:37 PM

the legacy will live on bill :twisted:

tpulliam79 05-04-2008 11:01 PM

so im thinking of taking the silver stuff out and replacing it with an acrylic box ( like on willwrens sleeper ) but im gonna coat it with wrinkle finish . just wondering if I should build it big enough for the reflectix to stay inside of it or if the coated acrylic (plexi) would keep it cool enough without it.. any suggestions? I gotta get this done before I go under the knife :cry:

willwren 05-05-2008 01:47 PM

Box with the reflectex in it would be rigid, strong, and very good. Just make a cardboard and tape template to get the basic shape of what you want, then cut it apart and use those pieces as the template for the acrylic/plexi.

well had some time yesterday and this is what I did : first relocated my pcm then on to my new box( mind you this was all done with just my left hand and I'm right handed)
cut the acrylic ( heavy duty this time) and wrinkle finished it hinges too this was all done with a razorblade a very low powered dremmel and a cheap drill

now my wife is going to paint something on the top of the box, haven't decided what yet maybe the Pontiac dart or the cars name? ( which it still doesn't have one
:oops: ) :shock:

Boreas 05-11-2008 03:41 AM

Very nice!

Id go for the dart.

Laxmangl 05-11-2008 08:05 AM

Looks great. I would go with the dart as well

Red Rocket 05-11-2008 10:09 AM

Very nice. :thumbup:

tpulliam79 05-11-2008 10:54 AM

well my wife is drawing it up and I think im going to have my cousin who is in the screenprinting business print out some decals of it and put that on there :D

phatklan 05-11-2008 12:33 PM

that looks nice

2000SilverBullet 05-11-2008 12:42 PM

Good job on the Cool Box. That not only looks good but will be effective..... as long as you keep the car moving and don't stop and idle too long.
:D

jarodsfisher 05-18-2008 03:53 PM

What has this done for your car in terms of mileage? Increase, decrease, nothing? If increase or decrease by how much approx?

GoldenBullet 05-18-2008 03:59 PM

that looks great :thumbup:

Jarod, you've asked this a hundred times in other topics. Please just believe the 1-2mpg we've told you and go try it for yourself.

2000SilverBullet 05-18-2008 07:43 PM

Remember that an engine is just an air pump. Reduce the restrictions on either end with gain more power and better efficiency and efficiency = mileage.

and ......

1% hp gain for every 10 F drop in intake temperature. ;)

a7morelli09 05-18-2008 10:13 PM

since black absorbes heat try painting the box white since that disipates heat it should help a lil bit more

willwren 05-18-2008 10:19 PM

A little off-base. That's the same coating I use to dissipate heat on the superchargers I rebuild. It's wrinkled to increase surface area.

A black car will COOL faster than a white car as well as heat up but ONLY if it's allowed to absorb heat. His has airflow over it constantly.

Google the 'black body' theory.

jarodsfisher 05-18-2008 10:38 PM

Will, I had only asked this question one time and your answer of "1-2 mpg under the right conditions" was the only answer that I got. I just wanted to get some other oppinions of what other peoples mods had done for them. Also no one else has answered the question, but you, so there is no "we" telling me anything. But Thanks.

tpulliam79 05-19-2008 01:11 AM

will is correct in saying 1-2 miles in optimum conditions... he happens to know quite a bit about these cars. and in my opinion his word is gold. and im sure its hard to tell for anyone with an intake as the acceleration is so much better its hard not to be into the gas :twisted:

jarodsfisher 05-19-2008 09:22 AM

tpulliam79, thank you for your response. that's all i wanted to know. Thanks.

willwren 05-19-2008 09:59 AM

Jarod, Tpulliam was at a meet at my place last month. I sent him home with 4mpg better than what he came down with. His drive down was primarily downhill, and in spite of the uphill drive home, he still got better mileage. Half that was probably the intake he installed while he was here. Primarily because he took the time to insulate it at least temporarily at that time.

fastblkbeauty 05-20-2008 03:57 AM

Bill...Taylor and I were racking our heads the other day when we worked on my car. On the '94, it has these little "side boxes" coming off of the air duct, WTF??? Is it not the correct understanding that a straight flow is best, why these empty boxes? Just a question. Will get pics posted if you need to see what I am talking about. Also, what exactly are you guys referring to with the "gutted air box" talk. What is gutted...want the CAI from i think Intense, but can't afford. (I like the looks of it, as well as want the improved MPG) Thanks. ~Brandon~

Bonneville92V688 05-20-2008 07:32 AM

The little "box" on the intake tube is a whine baffle, along with the ones on the intake snout of the air filter box. They were put there to quiet down the whine, as when buyers bought these cars new, they didn't want to hear the whine as it was sold as a sport luxury sedan. Now on the other hand, we love to rip that crap off to hear the lovely whine of the M62. 8)

Works the same way on alot of cars. My Dad's Durango had a huge baffle box to quiet down the roar at WOT, but that changed when we put a intake on. 8)

willwren 05-20-2008 08:34 AM

My 95 had the same resonators on the intake as your 94. Note I said HAD.

fastblkbeauty 05-20-2008 02:23 PM

hmm...quiet it down??? Oh hell yes they are coming out!!!! lol

Thanks guys :D

2000SilverBullet 05-20-2008 08:07 PM

There are some that would tell you that the resonation chambers are installed on the intake box to tune the intake for additional power. There were none of these on my OEM box.
Theory having something to do with energy pulses. :?

Elimination of them on new models could have been a cost saving measure by GM :?:

I love the whine..........almost as much as the wine here. :alcoholic:

My vote is rip it off and enjoy the sound and freer restriction. ;)
