This weeks episode of CarCast with Adam Carolla and the Professor Sandy Ganz bring Harold Osmer. Harold is the Author of “Where they Raced” a detailed book on Southern California racing from 1900 to 2000. Harry Pallenberg also joins and is working on the Documentary of ‘Where they Raced’. We toss in a special old recording of Adam’s version of the hyper-amped Drag racing radio promo you might hear back in the 1980’s. Another Tech segment? Yes, the Professor experiments with air filters and finds out that they can be renewed and which flows the best. Enjoy the show!

A great book that tells what part Los Angeles was in the birth of mortorsport in the United States.
A must read by any enthusiast.
Great tech segment!
nice job Sandy, that tech segment was actually interesting and entertaining.
enough with the “actually”. That’s not a compliment
hummm…
YIKES! I thihnk my dad owned a 51 Chevy truck. Nice job Mr Ganz–once again.
Thanks! And will pass along to the Crew as well as they work hard behind the scenes too!
Sandy
Another great episode, thanks guys.
Question, do you have contact information for Harry Pallenberg? I would love to ask him where he is having his documentary mixed. As I am a huge racing fan, a fan of LA history, and a sound mixer, I would really like to start speaking to him about his documentary as it’s post-sound needs.

See the “Donate and Help the Documentary” box at the bottom of the page.
Check the links above, the where they raced one is for Harry.

Thanks!
Finally some sidewalls on something.
Another cool tech segment, want to see more stuff like that……maybe as bonus video content though, as this kind of stuff doesn’t lend itself to the audio podcast version.
But back to my comment……….any idea if air was leaking past the gap between the box and filter?
Yeah, the Audio is the tricky part. It’s often shortened up a bit. We have more odd videos that will likely hit the video only section of the site, trying to bank up a few so we can have them ready to go during the week.

Sandy, that was a kick-ass tech segment. Awesome experiment. Thoroughly enjoyable, too. Thanks!
Professor,
Nice experiment, I always wondered what the real difference was in the air filters. I could always hear and feel the difference but it’s nice to see a visual digital readout of what really happens.
thanks for the great shows

Thanks, I also had a Cone filter kit for the Excursion, and didn’t have the to make an adapter for the the flow bench, well flow box. It had a bunch more surface area then the gauze filter and would work even better, but alas no time…
The one thing that the test did not perform is how well either would clean the air, I think the paper in that case would do much better. Always a trade off with something.

Talking about the wooden race tracks got me curious to see what else I could on the subject.
Holy shit, is that a fucking lion?! http://tinyurl.com/y8wydqg
good job on the flow test, especially the audio while the vac was running.
The issue with the k&n type filters is supposed to be that they let in a ton of dust to the engine. I have a couple of ideas to test that, lmk if you want them.
Couldn’t you have used a low-buck “carb stick” to get the relative flow? I mean, just fill a clear tube up with water, put one end in the plenum and one to still air. Used for tuning multiple carbs (at least in the motorbike world).
Good tech segment. I also enjoyed the “Where They Raced” portion, and where it was coming from, but I’m from Florida and NC.
As to the after-market filter, you say it can be rinsed; is that with soap and water, or a solvent? Also, the water-in-a-tube is a fine way to see the vacuum difference. Just use a u-shaped piece of glass tubing, mounted low in the side of the box,, half inside, half outside. Fill the tube so that it’s a bit more than half full of water (more, then it will spill out when you turn the vaccum on and off), and then watch how much it sucks the water down on the portion of the tube outside the box. The further down, the more clogged the filter.
You could see cleaning efficiency using a standard Smoke Test, used for testing respirators. Put a light inside the box and a little plexi window in the side of the box. You should be able to get a smoke test kit at a safety supply store; just puff the smoke over the filter and see how much passes into the box. I’m bothered by the filter that passes the most air being judged the best, if that filter also passes the most junk into the motor. I think the oiled/guaze filter would actually do very well in the smoke test, which is more important than it passing through the most air. After all, no filter will pass the most air of all!
