Darchangel posted:My S5 RX-7 actually does have a dual-length intake manifold. there's a barrel valve that switches the path at a certain RPM. Doesn't do as much on mine as it should, because my auxiliary ports (think VTEC, insofar as the ports provide more advanced intake timing and larger volume) are stuck closed. This is also how Mazda was able to squeeze 180rwhp (~230bhp) out of the 13B-MSP in the RX-8. Adding a CAI looses you HP/does nothing.

You should fix that poo poo because stuck ports totally suck on an FC. I remember driving my buddy's before and after we got his fifth port unstuck. Even with the sixth port still stuck it woke that little bastard up.

Adding semi-recent vehicles to the intake manifold chat, the SVT Focus had a dual-stage intake manifold. Now that I think about it I should start trawling the local salvage yards for a wrecked SVT - the intake swap is pretty much bolt off/on with the addition of a servo and RPM window switch to kick the runners over above 4k RPM. Other fun fact about the SVT Focus was its airbox had better flow characteristics with a drop-in panel filter than virtually every other cold air/short ram intake on the market

Is there any reason why no one hasn't just made an intake runner with what looks like a trombone slide to change the length? Then you don't need multiple paths or dummy tubes or individual throttle bodies and you get infinite variability.

Before someone beats me to it, been done at least by Mazda on the R26B engines on the 787B. Not street use though.

The LS and LT motors laugh in the face of fancy dohc motors.  Edit: Also holy gently caress, why would anyone willingly buy a 3 valve mod motor? When there are over $1000 in tools just for all the different ways you can have a spark plug change gently caress up, thats the point I say no.

Long_Tine_Spork posted:Actually someone has! Those are individual throttle bodies. The tubes extend and contract with rpm. In the world of production cars this can't exist because of emissions equipment and at filter boxes. Imagine trombone for a moment. The mouthpiece and horn start in the same location as the length of the instrument changes. This design incorporated into the intake of a car would allow one end to attach to the engine, and the other to be in a fixed location to allow things like an airbox to be mounted for production vehicles. Heck you could change the location of the port injection using a similar technique.

Some cars (BMW is the one I'm aware of) come with factory ITBs mounted inside of a large airbox, with a large enough filter/primary intake that the pressure inside it is essentially ambient. You could use a system like in the video with that setup.

I'm quite sure all N/A M cars have ITBs and there are quite a few other high performance oriented N/A engines with them as well. Flap based variable length inlets have been commonly used for 20 years in everyday cars. The sliding concentric trumpets are generally only used racing applications, probably because of complexity, reliability and cost.

BMW actually had a continuously variable intake on their N52 V8s, called "DIVA". I think it only ever wound up on that motor.

The closed cockpit of the KTM X-Bow racecar, the only one in the Bathurst 12h, just had its roof clamshell open and blind its driver. Good race this year.

They don't show in action in this video, but they did use it for a street legal vehicle in the Ferrari, The Ferrari and I believe the F12 as well, so streetable yes, practical not so much. https://www.youtube.com/watch?v=euul7DrTry8&t=52s Also if I understand what your describing correctly, using the trombone analogy, that would just increase plenum volume and not the runner length which is what you would need to affect to alter RPM characteristics.
