I'm a new member here and as of yet don't own a turbine, but I would love to one day! I've been tossing around the idea of removing the gas engine and installing a turbine into my kit car. I'm thinking it's probably not the most practical way of repowering, not very common, and the gas milage would probably stink! However people that know me would probably tell you that I'm known for not going the easy route to accomplish a task. I sort of like a challenge. What do you think, am I completely out of touch with reality? Is this something that has been done before? Some of the questions I have about turbines: 1. How fast do they need to idle to keep running? 2. What is a safe low RPM to prevent flameout once the car is in gear and moving. 3. How do you go about controlling the throttle? 4. Do turbines all take 24 volts to run and do they have generators to refresh battery charge? 5. What sort of maintenance is required to keep it running and how often? Here is where I'm thinking of installing the turbine.

Hi Theres been some turbine installations ,do a Google search for Boeing turbine car , generally old Boeing 502 engines used like this one on Ebay, www.ebay.com/itm/Boeing-502-9A-Jet-Turbine-Engine-With-Transmission-Rat-Rod-/251898564191?hash=item3aa6530e5f&vxp=mtr though I'm not certain about this actual one , bit hard to tell from the pics how its configured and/or condition . You need a "two shaft" engine for a road vehicle , single shaft APU types just aren't suitable without complicated gearboxes . A two shaft engine can have the freepower "second shaft" ( N2) stationary even with the gas producer "first shaft" ( N1) at max rpm , so theres no complication with the installation , very similar characteristics to a car with auto gearbox . Safe gas producer rpm ( N1) is generally ~40% of max rpm , but N2 can go from 0 to 100% . Throttle control is the same as a diesel , just feed more fuel when you want to get more power , simple . 24 volts isn't probably always necessary , some have generators , some drive generators . Turbines generally require little maintenance , thats one of their good points .............how often , it'd depend on what you used And yes, your MPG will be horrendous . Cheers John
