That's a lot kinder than what the Mustang guys called it...

I started to play around with some shapes and ended up with this monstrosity. It's actually for the Mustang as a faux ITB air cleaner that goes into a single carb. But it was a good exercise into merging multiple extrusions (lofts) into one unit.

It was about a dozen clicks from a blank diagram to a printed piece. I just did this to see what it was like. About an hour to print out. Next will be to start getting actual dimensions.

I'm not convinced that CFD is the best indicator of real world performance. The YouTube videos of dyno runs with different stacks seems to support that. Although I'll concede that YouTube videos are pretty limited in the testing.

Interesting. The velocity stack should sound even worse! Speaking of velocity stacks I've watched a couple videos of people testing different stack designs and you can barely tell the difference on the dyno. I doubt you'd notice on the track. Even a Ramen cup did fine. Which is all to say that I probably can't mess this up too badly!

As cheap as Guzzi people are you’ll be lucky to get $10 bills.

Also if anyone can think of another part they’d want designed and tested let me know.

Nice! I’d be a little concerned that it might crack along the lamination lines but if it was printed with enough infill and thick walls it should be ok. Let us know how they do.

I’m open to ideas!

I recalled some conversations about air boxes like this one I just got a new 3D printer (Bambu P1S) and I've been busy making stuff. As part of this I'm learning OnShape, which I'm finding more intuitive than Fusion, which I also tried. I'm finding that if I find practical (or even semi practical) projects it helps me learn the CAD app better. The nice thing is that the printer is nearly flawless. I had a small printer many years ago (something like 2016) and I remember having to futz with the printer a lot. Now it's nearly pushing a button and waiting. And even though the printer is much, much faster it still takes time to print. The other thing that's changed is the materials you can print with. There is a huge variety with a variety of properties. Where was I? Ah, projects. In thinking about fun projects I thought that a custom air box would be interesting. The print area is approximately 256mm cubed so it will need to be made in sections. I may just start by making some velocity stacks. Then go from there.

I wish I could take credit but alas, I can't.

So it appears that the seat style doesn't have a lot to do with how sporty you want to be.

That seat looks very good and comfortable. The leather looks awesome and while it will require more maintenance, @ChrisPDX is the perfect person to tend to it. Me, on the other hand, would have it rotting in a week. Chris has mentioned to me that he'd like to take the bike touring. As he road races now (and has for a very long time) he doesn't the urge to drag pegs on the street. That's only for posers who don't actually race.

When you say "old duffers"... you mean everyone here, correct?
