jon haney Posted October 25, 2022 Share Posted October 25, 2022 Thanks, Carlos. However, after reading "Beetle running gear", I feel like a beautiful women has just undressed in front of me, only to reveal a penis. Sigh. Quote Link to comment Share on other sites More sharing options...

On the upside, you can make big power with a VW motor and they're light. Quote Link to comment Share on other sites More sharing options...

Every vehicle can be made fast with enough money. Two real Birds lovingly connected with some chrome moly tubing and fiberglass has got to cost less than a souped-up VW motor that would push that rig to the same 1/4 mile time.

XXitanium Posted October 27, 2022 Share Posted October 27, 2022 To street it, it would need some steering geometry figured out. On a 4 wheel system the inside front wheel and the outside have different instantaneous centers for their turning radii. I have never been on a drag strip, but I stayed at a Holiday Inn Express last night ir some shit... Quote Link to comment Share on other sites More sharing options...

It's called Ackerman, and can be one of the toughest things to get right. Even many production vehicles don't get it right, I mostly notice it with trucks/vans. That would only be one of the challenges of getting two bikes working as a car, and one of the least likely to try to kill you if you get it wrong.

Forgot about the front geometry equation. I've seen a side-car rig that had a front "swing-arm" setup with center-hub steering. Probably have to go that way to make it work. Come on lottery!

Takes some getting used to. I think I would rather build something with 2 Bird motors, and be able to ride/drive it in the rain without getting wet. Thanks for posting the video link. I had never seen that. Edited October 28, 2022 by jon haney Quote Link to comment Share on other sites More sharing options...

There isn’t really a better or worse, it’s what the vehicle needs. Typically you want toe in. I’ve heard that some front wheel drive vehicles have close to zero or maybe a bit of toe out. I assume it’s because they plan on the power pulling the wheels forward and toeing in slightly. Quote Link to comment Share on other sites More sharing options...

I think it would work OK with a simple tie rod connecting the two together. It would have excessive caster, but not a huge deal. It would be like steering a motorcycle with a fixed side car.

SwampNut Posted October 29, 2022 Share Posted October 29, 2022 Toe out on a Jeep *may* lead to Death Wobble and lots of toe in is very stable but weird feeling. Then again, looking at a Jeep with a funny face leads to DW so who knows. Quote Link to comment Share on other sites More sharing options...

blackhawkxx Posted October 31, 2022 Share Posted October 31, 2022 I'll take the turbo and NOS. 🙂 I'm guessing the bike isn't finished as I see no exhaust. Quote Link to comment Share on other sites More sharing options...

The bottle is probably for an air shifter, not NOS. It might just have a short pipe that's not visible. Quote Link to comment Share on other sites More sharing options...

After making the photo bigger, I think you are right about the bottle but there is no way the exhaust is that short on a drag bike not at least on any that I have seen in my lifetime.

With a NA motor you want some length after the collector, a super short pipe would rob power so it would be silly to do it. With a turbo it pretty much doesn't matter so it could be a super short pipe in the belly of the fairing, or it might be poking out the other side. A turbo outlet pipe is very simple so I wouldn't suspect that to be 'the one part we haven't gotten around to'. Quote Link to comment Share on other sites More sharing options...

The exhaust may exit on the left in the bike in question.

Have you ever seen that on a fast drag bike? Quote Link to comment Share on other sites More sharing options...
