Hey all,
It's your local fabrication-happy maniac back again for yet another installment of metal mania madness!
😛
As your're all well aware by now, my build relies pretty heavily on many custom fabricated components and areas on the car. I have no excuse for this other than I have an active imagination and can visualize certain concepts that would lend themselves great in certain areas. That, and I love to create that "one off" part or idea that no one else has.
By now I've been in and around the car scene long enough to become a bit jaded, and I tend to grow bored with the common things guys do with their rides. Kinda sucks to go to car shows with me as I'm sure my friends can attest...!!! Anyways, how this relates to this latest installment on the thread is I'm going to cover the air intake/induction system.
Usually, the #1 thing that a guy tends to see wandering around the local show is the dreaded "14 inch air cleaner".
Now before you all jump up and down and send me nasty replies as to how there's nothing wrong with chrome 14" air cleaners, and you have one on your car, hear me out. You're absolutely right, there's definitely nothing wrong with them, they're usually one of the first things to get installed when starting performance upgrades. They look great, they're cheap, easy to install, and you get that great roar from the carb when you mash the loud pedal! Lotza fun, no doubt. But I made that mod about 20 minutes after buying my first car, and it's just not as exciting anymore. Cue my active imagination...
One of the things I like to do when searching for inspiration or that next new idea, is to actually look backwards, to the past. The factory designers and engineers all had great and innovative ideas over the years that they implemented, some successfully, some not so much so. The Cowl Induction hood and air filter arrangement for example is popular, but that was a Chevy thing, and I wanted to stay more true to Olds heritage. One of Oldsmobile's popular options during the musclecar wars of the 60's and early 70's was their version of ram or cold air Induction. While certainly not a new idea, Olds used several various versions over the years, from ducting it in from beneath the bumper in the '69 W30 442's to ramming it in through 2 big scoops on the hood in the '70 models. The '66 and '67 442's used a twin snorkle housing, flexible ducting, and pulled it in from in between the headlights. This was my inspiration point, but it needed my own unique twist...
One of my pet peeves about our G body cars is the poorly fitting rubbery plasticky filler panels that fill in the gaps around the 5 MPH bumpers. They're even worse on the early '78-80 G's and the chrome bumpers. I knew I was going to do a bumper tuck inwards and back on the front bumper, so using the factory filler panels was out for sure anyways. I found some tasteful and somewhat stealthy perforated mesh sheetmetal that was thick enough for me to weld to, and I made part of the filler panel below the headlights with that. When this piece gets painted body color, you'd be hard pressed to notice it's not solid and supplies cool air to the filters I think!
Here, the bumper tuck has already been completed, trim and holes removed, the licence plate recess has been eliminated, and the new filler panel with the mesh has been created. The cardboard taped to the hood is the beginnings of seeing how my own version of a wide cowl hood would look. (I need the hood clearance!) I will cover that soon, but there are pictures of the hood build on my profile page under "albums" if you can't wait that long!
Lol
So the mesh part of the filler panel is now the external intake to get cold air to the filters. After some trial and error with filter sizing vs. engine airflow requirements, I decided on dual conical filters. These would be mounted out and down off of the radiator support on the grille side of the rad support. From there, ducting would route from the backside of the core support and up to the carb. I started by simply bolting some sheetmetal to the opening in the rad support behind the headlights and mounting up mandrel bent 4" exhaust tubing from a muffler shop.
Once that was done, it was time to turn my attention to the carb part. My inspiration was actually the Shotgun Bill Scoop from Speedway Motors. I've always loved the look of it, but for it to look at home on an engine, it pretty much needs to be mounted on a blower motor sticking out of the hood. For those not familiar with what it looks like, this is it.
Something like this would obviously not fly with my build theme, but what if I took the general shape and continued it down towards the front of the car? Maybe something like this....
Ok, I think I was on to something, but it needed a little more refining, and the bends in just the right places...
I decided to make most of it one piece, with the joints down low away from the engine, so as not to be distracting. The underside of the portion that sits on top of the carb has been "hollowed out", fully welded, tapered and radiused so as to not restrict airflow. The tubular portion you actually see sits on top and gets bolted to a secondary "carb plate" that is bolted to the carb itself. If you look REALLY closely in the previous pic, you can just see the bolt heads visible.
Of course, I just HAD to see what it would look like from the driver's seat!
😀
It was starting to match what I was envisioning, but something still wasn't quite right...the overhang on the back of the carb didn't look right, not natural. That called for trimming the back at a 45 degree angle and capping off the ends.
Yeah, that was definitely what it needed. Now it didn't look so "heavy" back there. Then, it was a matter of getting some nice 4" diameter silicone coupling sleeves, clamps, and a trip to my machinist friend for some custom trim rings to mount the elbows to the rad support.
And then the nearly finished product - ready for a bit of filler, primer, and paint.
I know this isn't exactly going to be everyone's "cup of tea", but nothing on this car has ever been built with the notion of anyone else's approval other than mine. I'm gonna get the haters, and the idiots that think it's somehow a turbo car. This car will never win a "people's choice" award at a show, there's just too many things that people can and will take exception to. But then, I don't really care. This is
MY car. It has been built for no one other than me, it reflects my tastes and personality, and I don't expect that everyone will like it. More importantly, it's unique, individual, and will be the only one of it's kind.
No fear of having mine confused with "that other one" rockin' the 14" chrome air cleaner!
Thanks for watching/reading/following guys!
