Turbo-Mini (bike)

[FASTBACK340]

One of my co-workers brought in his mini bike to finish welding his exhaust he made. That's a VW GTI turbo blowing into the engine.

Carbon Fiber underwear optional.

That is WILD...!!! Id love to find a turbo or paxton to convert to belt drive and put it on our truck.

That is sick. I love the recent resurgence of the mini bike scene over the last few years.

Not to spoil anyone's fun, but a turbo sized for a 2 liter (or thereabouts) engine isn't really going to work on a tiny scooter mill. There may not be enough exhaust gas volume to spin the thing fast enough to make any boost at all.

Considering how microscopic modern turbos are, I wonder how well that would actually work.

Like most things in the real mechanical world, sizing turbochargers correctly for a particular application takes some applied knowledge, and (gasp !!!) math. Things like mass flow and pressure ratio at redline, area / radius ratio of both compressor and turbine, trim, and other factors must be calculated and mapped for any hope of good performance.

Your absolutely correct Ace. If you look closely there's no oil feed line either, which means this is pure "wow" and not very fast.

When your cruising the swap meet it's just profiling.... but it is cool .
