Could it be done?.....a gas turbine powered 240D? - Page 2 - PeachParts Mercedes-Benz Forum

You could always build your own out of an old turbo off of a "Robbie" and bolt it to the back! That would be mighty interesting.

I have a Solar T62-32 sitting at the shop. It puts out about 150HP. It's supposed to go into some sort of aircraft project but it would work pretty well in a car. One problem is that it's not very throttleable - maybe varies between 4000 to 6000 RPM.

I think you could use it for a turbine/electric hybrid or possibly a hydrostatic link to a standard automatic tranny.

Here a picture of a T62-32:

I really love turbines and jets and such. One day i would like to turbine swap into an old chevy Corvair! Run the turbine exhaust up out the rear hatch! I had somthing along the lines of a Pratt & Whitney PT-6 for power. The thing is ya theres not much touque but at the output rpm these run at and run through quite a gear reduction should net some good numbers. On a Corvair, i'd use a stout IRS axle and mount the turbine so the output shaft runs to the front and into a V-drive. Also need to give the turbine a good intake airpath as much CFM these pull in. Not only are turbines kinda slow to spool-up but slowing down too. That makes very, very good brakes a must! and taken into account when driving. Some old turbine projects had "wastegates" installed to immediatlly slow the turbine down. Now one more consideration, some alot ofturbines have a dual stage exhaust turbine system. Think of a turbo where the compressor and turbine are rigidly linked by the shaft, thats how a single stage type is, a dual would have the same and an additional exhaust turbine section not linked to the 1st, this would be the output shaft driving stage. there called the power turbine assembly and the output turbine assembly, think of it as how a torque converter works. Now the output turbine couples by the gasses flowing through it to but can have independant movment. That turbine can not stand stopped or slowed from the power turbine for too long before it overheats. Look up the 1968 Howmet TX turbine race car, the only turbine to win 24 hrs of Le Mans. IIRC when the Howmet was running and wasnt moving, they had the rear wheels off the ground so they could spin and keep from cooking the output turbine! Pretty cool car, think it was the car the wastgates were employed too.

Yeah, a 2 stage would be the way to go. Something like an Allison C 250 out of a Hughes 500... If you have a spare $10,000 laying around...

Got whatcha need right here:

One of our motorcoach buddies got bored.

One of our locals has a small GPU turbine in his Cub Cadet garden tractor, ... so I'm sure there's one to fit a 240D.
