Umm i think we can safely say theres not a car currently in production on the planet (except maybe Skoda) that are still using carbies. Your mates are clearly from the V8 dinosaur set. Even most V8 guys realise fuel injection is the way to go nowadays.

As you may or may not be aware theres two types of fuel delivery systems, one primitive (carburettors) and one modern (fuel injection).

Kinda offtopic, but why do brand new motorbikes still use carbies? Surely it can't add much more to the price to chuck an ECU in there. I remember being amazed that my 94 CC Lancer used one, but then I found out that 2003 model Kawasaki 250cc bikes are using them!

ah ok, so then I suppose if they slide (which I take to mean they adjust themselves and aren't locked for efficiency at a single point), then they would be almost as efficient as EFI as they aren't just set to be optimal at a particular rev point. Am I totally off? I've got no knowledge of pre EFI tech at all really :D

I can't think of any current model sportsbike that hasn't swapped over to fuel injection. The Yamaha R6 and R1 were 2 of the last to change over.

The difference on bikes with carbs and injectors is not that great. You can get virtually as much power out of flatside carbs on a bike as fuel injection, you will just suffer a tiny bit of response and economy. Even though it is cheap to put an ECU and injectors in, carbs were still generally cheaper (until recently at least). The main reason why Yamaha finally made the move is because everyone else did it, and was therefore a marketing ploy rather than a performance one.

The biggest problem with carbs on bikes is tuning the buggers.

Edit: Many Jap "cruiser" type bikes still use carbs, but this is more to do with the "image" of trying to look like a Harley. Again, marketing.

Majority of new bikes use injection, any that don't is cos its more cost affective.

I was only out at the track a few weeks back and there was a 1600 running an SR20DE with twin sideys (personally i would have gone quad throttle bodys if anything).

and i am sure some of u guys have seen the S14 drag car running an L31(stroked L28) with twin turbos and triple webbers? that thing as mad!!

could someone verify for me if it was running methonol? and possibly nitrous?

    • Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!
    • Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.
    • Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 馃槂
    • You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position. 
    • You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
