We’re working on it still. After a few different exhaust configurations, we mainly settled on the one that would allow us to complete the testing schedule with the least amount of expense, to be followed by a more refined muffler/exhaust system.

Actually, it was never a jet-thrust type engine. Out of the factory it was designed as a turboprop, to be used with its integrated gear reduction to drive a propeller shaft. We could be pedantic about it, but I think to most people “jet engine” makes more sense than any kind of more in-depth distinction.

Not quite single digits, lol. We’re looking at (steady state) about 26-32 mpg, extrapolating from what data we have at this point. It’s a bit weird, because it’s running steady state most of the time and eating the same amount of fuel whether you’re going 30 mph or 60, so fuel economy is a bit wonky to calculate.

It’s in fact a JetCat SPT-15RX turboprop. The engine itself provides about 15kW (20 if you really wanted to redline it). Thanks for pointing out that I was unclear on the description; the *generator* is capable of 60hp (about 40kW), so we have room to upsize the turbine if we ever found a bigger one.

I used to do FSAE Hybrid and Electric while I was still in undergrad. We’re currently running about as basic a driveline as it gets, with a nice and torque-y DC motor coupled straight to the stock tranny. The batteries we’re using are LiNMC Enerdel units, with an Orion BMS.

We’re...kinda working on it :P I’m kind of social media illiterate, so while we have huge amounts of build documentation, I still have to sort through it and put it up on our website and instagram.
