- 0:01We haven't heard, we haven't heard a lick of, driver response, you know, driver response times upkeep. We, we don't hear anything. Do you all even drive?
- 0:02Rose BB14: gonna happen. She said, no,
- 0:03Emily BB14: He said headers are tubular exhaust manifolds. They're typically equal length for each cylinder, and we're designed to help the engine breathe so the exhaust doesn't get caught up in the earlier log type manifolds. So pretty much, I mean, that
- 0:04Emily BB14: So they're, uh, the manifolds are cast iron, sorry,
- 0:05Emily BB14: Okay. Sure. They're all cast iron as far as I'm concerned.
- 0:06headers scavenge the exhaust gas. Pulse flows out of the header tube and into the collector creating a negative pressure wave that will travel back up the header tube during valve overlap.
- 0:07Rose BB14: Well, the advantage of a header is that you have a consistent shape for each sonder, so you do have more balanced shapes and volumes. Like Ryan said, something that I think is a little unspoken in this is that the inside is less consistent. I'm not saying it's a really wonky casting, 'cause the inside molds are nice, but it's not like a tube, you know, a mandrel drawn tube that's consistent everywhere.
- 0:08You can get short tube headers, long tube headers. I like to call them nut hugger headers. They call them block huggers, but I call 'em nut huggers. They are just, they're right against the block and. It's not much different than a manifold. But the reason why I thought that we had a little bit of hair splitting to do on this topic is that there are things like the rams horn manifold from Chevy that is a pretty good flowing.
- 0:09A ceramic coating. There's different coatings. 'Cause heat with headers is a big deal. Headers next to your starter, your starter will go through what's called heat soak. Right. So the header puts off quite a bit more heat, and it, you know, it winds up going over to your starter. Well, heat is resistance in an electrical circuit.
- 0:10Rose BB14: that becomes a problem. So people will put a stainless steel, you know, stainless is not a great conductor, so they'll put. Stainless steel shields over their starter or aluminum shields or something that does help.
- 0:11Rose BB14: I'm a little of the, like, I don't believe in back pressure, like it's the boogeyman, like there has to be something, right? There's like, but back pressure is weird. But I mean, there is pressure for sure. And then the size of the quote unquote primary tubes on the header.
- 0:12Emily BB14: I won't. Yeah. I love that answer. Great. Thank you for also answering my question. Yeah,
- 0:13Rose BB14: but it would, it could be funny, but I was like, and then I, contemplated going to O'Reilly's and pretending that I don't know what headers are and asking them. But I was like, I don't think I could ever go back in there again. They would just, they'd think I'm a moron because I don't know what headers are. I don't know. It's nice that our listeners go out and to the world and figure this stuff out.
- 0:14Rose BB14: Hide the ball into the
- 0:15It was sick. Uh,
- 0:16Rose BB14: I'm gonna give you a hint. Spear in the whale would work really good with steering wheel. We've got the spear in the whale. I'm hitting the road, grabbing my steering wheel.
- 0:17Rose BB14: Fun to drive, he said. Yep. Gina also piped back in and said, Dean knew this answer as well, and Benny said, I don't care. I'm just kidding.
- 0:18Well, um, yeah, I think that Jesse said that, you know, because it was supposedly that you could drop rocks in it and just keep on going and crush 'em up and whatever, which, yeah, probably, I mean, tool steel's harder than some rocks.
- 0:19Rose BB14: Yeah. I'll say that. A few other people got this one right. This was not a singular thing. So the whole deal with this trans is that's French or is it, Spanish?
- 0:20If they did the M 20, the M 21 Muncie, and that means that they're made in their plant. So it's not a Muncie brand, it's actually just made at the Muncie Indiana plant. And if you watch Parks and Rex, then you know about taking vacation in Muncie.
- 0:21Rose BB14: Ter Haute. Fuck off Larry Bird. Anyway, the Muncie plant,
- 0:22They have a straight cut gear and that's why the car sounds like it has a blower. And it's actually just that timing gear.
- 0:23Emily BB14: Sorry, I didn't mean to discredit that designer. What was his name again? Her name. Was it a girl? F-O-D-R-E guy?
- 0:24Rose BB14: Is inside the lines of your brake system when you mash that big hairy Bigfoot Sasquatch slipper, not your actual foot down on the pedal below, what? And I'll let you go in hundreds of PSI below what PSI, I've already limited it, right? We're below thousands because I said hundreds. I'll give you that below.
- 0:25Emily BB14: My favorite kind of. Class of a car. Class of a car. What does that mean? Favorite style of a car?
- 0:26Rose BB14: Chrysler Small block. How do you build a good three 18? Build a 360.
