Ok, I'm not actually looking to put a fan in my exhaust pipe. Since this is the primary brainstorming section, I figured I might brainstorm using what Paul had quoted. Maybe I'm not being too clear. Actually, I may seem totally out of it.

No way will I rice my Bonneville with a fan in the exhaust. Unless it'* not ricing. I would find that hard to believe, though. The guy with the N-body Oldsmobile coupe who has two engines in his car posted here about brushes that clean oil off of camshaft lobes to lessen rotating mass, as I'm told. I remember this was disqualified for being nuts, but on 3800pro.com, it was a confirmed way "to gain performance."

I'm trying to keep up the brainstorming nature. The guy that coined the word and came up with the process said it'* easier to tame a wild idea than (insert proper words here: to liven) a boring idea.

Going with this original brainstorming promotion, I wrote out the fan in the 4-inch exhaust idea to do two things:
1.) To ask why it is that supercharged and turbo engines don't require much babying by the exhaust piping.
2.) For comic relief.

On the base brainstorming level, I brought up a fan in an exhaust pipe capable of fitting a fan big enough. I used that to try to see what you guys think would happen if vacuum took over natural flow.

So, how do we stand now?

Frankly, I feel like a fool for participating. I wish you'd been alot more clear from the get-go on this one.

Let'* try to keep it practical from now on, or CLEARLY state your intentions from the start.

I suppose theoretically if you sucked hard enough you could create negative pressure.......sort of like supercharging the exhaust.

:(

We can learn more by starting with overgeneralized ideas and narrowing things down to what we want to know. Why get mad over this? It'* absolutely impractical to put a fan in an exhaust pipe, but I asked about it in wanting to know about exhaust flow.

If we need to keep everything practical to keep the thread moving so I can figure out some more things, that'* fine. It'* not too tough to get some use out of my crazy posts, though. rrounds had quoted Scott Stutler, and Paul added some info and quoted rrounds. Considering that, I asked:
"Well, does that mean I can put a 4" straight pipe out of the back of my catalytic converter?"

That may not be a yes or no question. It seems logical, though, to try to explain the effect of 4" piping out of the catalytic converter, if there really is one. I had read earlier both before and after I mentioned 1337ssei'* 3" catback exhaust, about why not to do that until you're in the low 13s or so. Is it just money and weight with a forced induction car?

I didn't say I was mad. Call it frustration. I'm not the only one, either. The point I'm making is to clearly state it'* theoretical at best, and you don't actually plan on putting in vacuum pumps, fans, or 4" exhaust piping.

That'* called communication. It keeps other members from feeling frustrated when you don't seem to be getting the point.

Oh, I see. That makes a lot of sense. Thanks a lot for clarifying. Well, if anyone knows more about exhaust flow, please feel free to post it. Hopefully this will catch on again so I can read more about what you guys think.
