Hi all, long time no chat. So I built from scratch a side by side go kart. Made the frame from steel and used a Toyota 5 speed manual trans and transfer case and Toyota axles. For an engine I used a 418cc air cooled diesel and belt clutch setup and chain reduction drive onto an adapter into the Toyota transmission. This last weekend, the engine cracked in half. Looked like maybe some bolts worked loose that held the back plate on the case and it lost strength and just vibrated the top of the block off. Seeing as how I need a new power plant and I always wanted to do some turbine ideas, I'm here to ask about an idea I had.
What if somewhere I mount say a 8hp gas engine driving an air compressor of some type, and then use the turbine section of a turbo driving a reduction gearbox to the transmission? Sort of a hybrid unit. Converting a turbo to a turboshaft would be just so laggy and only work at full power really. I'm thinking a motor powering the compressor stage would work great. Any ideas guys?
8 HP won't do anything as the power for an air compressor feeding a turbine :-( a small GT40 sized turbo's comp wheel consumes >80 HP from its turb wheel
LAG, ...... what lag .... LOL, you need to reassess that, a turbo based gas turbine engine's gas propducer accelerates as quickly as an IC engine , a gas turbine engine idles at ~40% of max RPM , it takes no time to reach 100% .
There are heaps of turbine shaft powered examples in the DIY Section .
I'm thinking for a simple design for the power turbine to take a steel hub maybe 4 inch diameter and 2 inch depth, drill holes around the outside of it where they are partially open towards the outside and I can use pins to lock in place strips of material as the vanes. This way the vane strips don't need to be the same material as the hub. And could be replaced too. I'd imagine the vanes and outside of the assembly would be the hottest.
I'll look through here more today. I'm so lucky to have you guys to answer questions I may have asked years ago and forgot 😅
