I was rolling through my CAD portfolio site and came across these. I know a couple folks here have done some interesting ITB/custom plenum things. I dunno, here is a little something to get some ideas out there.

Idea 1: My first idea for one...the early days of my CADing.

Idea 2: A little more CAD experience and fuel injector idea from Ferrari F1 motor
See the attachment at the bottom for a little artistic license I took with it. The heat shield was more or less real. I made one from aluminum sheet and made a CAD version of it after. I even made a wood mold & bought a vacuum pump so I could bag a CF one (had the fabric & marine epoxy). I just never got around to it, and am sticking with the OE filterbox on my 2nd M42.

I still have the model for the injectors if anyone wants a copy. They were made from measurements I took from real ones. Lemme know what format you want them in and I will do what I can. STEP is probably the easiest, and I use IronCAD anyway so the feature data would be lost in any translation.

There is a bunch more stuff over there too:

I have models I made for custom coil-overs, custom AL flywheel and an exploded I4 engine. The engine model...it is a veritable Where's Waldo of "find the mistakes in the design." I sorta did it off the top of my head when I was 19 in my spare time one week. I keep meaning to do it again, for real. I have a thread for that too lol.

Oh my god :eek:
I'm a total ignorant of the CAD... but that is sick:D
Did you realise them (ITBs) or is only for show your CAD's abilities?
I've checked your portfolio, you are insane:p
great work man!

The TB design was off the top of my head, sorta made it up as I went. You can tell, too by looking at the injector bungs. Sorta goofy lookin, but I got short on room. I was 19 at the time & had not really torn into my motor at all.

The second one was after doing a couple teardowns, a good 3 years of reading & discussing concepts, seeing real-world designs, building a Megasquirt management system and a plethora of other stuff.

BTW, who all here has custom intake manifolds on their ride?

Wow!!!

don't applaud yet.

I bought this car sight unseen and thought it had a stock intake manifold on it. But instead it had this.

The car is using all of the STOCK motronic EFI components and it just doesn't run right. If I blip the throttle it behaves like I need an accelerator pump. I also have a weird stall-recover-stall-recover-stall-recover... issue at around 2800 rpm. I towed the car home to Cincinnati from Denver and have yet to drive it further than the driveway which is why I joined this board. Trying to see if I can make the stock components work before going to aftermarket.

I'm sure it must be running lean and need a new fuel map but it would nice if the efi would compensate.

The problem seems so similar to others that I have read about so it makes me think there is just some stock peice that wasn't used correctly or was damaged. As I don't have a good m42 as a basis so I have to rely on Bently, Haynes, BMW and you guys.

Bently, Haynes and BMW have been kind of lacking so it's up to you guys.

I'll trade manifolds with you

Nice CAD work! :cool:

Nice to see the aluminum texture on the tb but you can also see the imperfect overlap on the CF. Get rid of the ricer blue coupler. j/k. :p

Haha yeah I need a better CF texture. That one is just a pic I nabbed from Tap Plastics' web site!

Yes, the coupler could stand to be black. Buuuuuuuuut...crazy colored couplers and hoses add 25hp to the wheels per foot. It's true, I looked it up in Sport Compact Car magazine :rolleyes:
Hehe I used to browse through those at Barnes & Noble just for a laugh...now I am embarassed to be seen tuoching one. Fuuuuh raaaaze suckas.
