Cowl Induction and other things

[Jeffrey Osstyn]

Here are a couple things I did my way. Cowl Induction was made with 2 pizza pans, parts from an old Chevy truck air cleaner and a lot of fabrication. Both aluminum and steel were used. I also moved the battery to the trunk to give me room for the MSD box, I wanted all the main power items to be on the same side as the starter so alternator was moved to passenger side. Main power and ignition power connections are located next to the MSD box on a terminal strip with relays and short circuit protection devices nearby. Power steering is a mix of Jaguar remote reservoir and old Chevy pump with modified tank. Steering is Global West bump steer correction and a 600 series box. Radiator is Eastwood tri-flow modified so it would clear the steering box. Also the radiator support was modified so the radiator would fit. Upper control arms are also Global West pieces with 6 degs added caster. Also has 2" drop spindles and disc brakes.

The air cleaner is very nice. Pizza trays sure do come in handy!

Very nice .........you do nice work

Beautiful !!!!!

Looks really good!

Thanks for the complements, I have way more hours in that then I care to admit. But hey, it was fun and I learned a lot doing it. The difference between an amateur and a professional is: the professional has done it way more times than the amateur, and he has gotten all the mistakes out of the way! But the final results can always be the same, just takes longer.

awesome work jeffery, that cowl air cleaner would be an easy sell if it weren't so labor intensive...

Very nice fab work Jeff but can you still bake pizza with the pans ?

Awesome Job. I'll have Sausage and Mushrooms, on mine, Thanks.

I thought about it, probably could cut down on the labor if I made a mold and did most of it in fiberglass. Not sure if that would be something anyone would want.

I like the idea of fiberglass for an air cleaner.It would help insulate the incoming air from engine heat which is among the main reasons for using cowl induction anyway.

Kooll...most excelent!

Hey Don
Just wondering, are you thinking fiberglass may be better than aluminum, or am I reading you wrong?

[Don Jacks]

Yes,Dave,that's what I'm thinking,but I may be FOS.

I wouldn't think the heat sink capabilities would be much different between the two materials. Mabye someone schooled in that area has an answer Don.

I wondered about using Peel and Seal roofing materiel on the bottom side to combat the heat transfer.

The bottom would be hotter, but engine heat would be all around. About anything a person did to insulate probably wouldn't be pretty. I thought about spray foam and have the pipe inside a jig to contain it.

That why I always keep my hood open in the staging lanes.

 

[Jim Sullivan]

I would think that as long as the car and air is moving, opened throttle, through the ducts, it wouldn't have time to absorb too much of the heat from the housing. Now if you were in traffic, not moving very fast, it would probably pick up some heat from the housing. Fiberglass probably wouldn't hold/transfer the heat like aluminum, but the fiberglass isn't as heat resistant and may deform or crack over time.

So what was the original piece made of? I live in AZ. and I have TBI on mine so I can see what the IAT is. On a 100 deg day sitting in traffic my IAT would climb to 135 deg. and above. YIKES! After the install of cowl induction IAT rarely exceeds 115 deg. much better. One issue I did have was noise. When I opened my fresh air vent, passenger side, I had loud weird noises. Not knowing what it was, I pulled over and opened the hood to see what was wrong. Figured it out, nothing, I had a direct connection to the TBI inlet and all engine noises were amplified and funneled into my cowl and passenger compartment.
Has anyone louvered the inner fenders in an attempt to give the under hood hot air a way out? If so, did it work? And what direction were the punches placed.
