I know it has been done in the past but I want to try it for myself. I would like to take a turboshaft engine from a helicopter or other such vehicle and retro-fit it into an automobile. My Question is what kind of engine would be best suited for an automobile?? I would like it to have somewhere in the neighborhood of 500+ Shaft HP and Second, What kind of a transmission would work best for this application. The size of the entire assembly isnt really a concern so I Am looking for the best power to weight ratio.
Any Imput would be appreciated.

good luck,chrysler spent millions doing that and you dont see any one the road

In addition to the other drawbacks mentioned, perhaps the biggest one is the spool up time associated with jet engines. When you step on the gas pedal in a car, the engines spins up very quickly and you accelerate right away. If you were to step on a gas pedal in a car that had a jet engine in it, it would take a couple/few seconds for the car to get moving. This isn't a big deal for airplanes because they typically only have to accelerate on takeoff. A high performance sports car, with a regular gas engine, would be much quicker at 0 - 60 than a car with a jet engine, assuming we're not talking F-22 type performance (and even then, I'm not sure who'd win but I'd bet that google would know). A pro for a jet engine is that it is more reliable and would last longer.

"what kind of engine would be best suited for an automobile?"
Not a turboshaft, or a turbine of any sort. They're fuel hogs and they have *no* bottom end torque. This project is a money pit.
"I would like it to have somewhere in the neighborhood of 500+ Shaft HP"
It shouldn't be a problem to find an engine w/ approximately 500bhp, the problem will be buying it and installing it.
"What kind of a transmission would work best for this application."
Depends on the speed of the output shaft. You're going to want your trans-> final drive ratio to be reasonable, shaft speeds are likely to be quite high so it would probably be quite a reduction so that you can multiply the non-existant torque into usable power.
"The size of the entire assembly isnt really a concern"
That's good.
"I Am looking for the best power to weight ratio."
Unless you're building a race-car you won't find it with this application.

Chrysler tried this without any success. The biggest problem is that turbines create power at the upper end of the rpm band and transmitting that power to road wheels is a mechanical nightmare. For example you have a turbo shaft engine running at 12000 RPM and you need to slow the vehicle down to where the tires are turning at 40 RPM. Noise is another factor. The exhaust is going to be loud and hot. you will have to somehow quiet it and cool it down to be street-able.
The best running examples I know of are listed on this site http://www.draglist.com/stories/SOD-Nov-2002/SOD-112502.htm

Jet engine to rear wheel transfer involves a high degree of engineering accumine.This kind of refixing entails a great level of knowledge and experience.Money will buy you all you want but-the satissfaction of your fears will never come to pass.Fear will drown you if given the forum. A healthy way forward is to dissect your fears to the root cause and to overcome them piece by piece in a way that does'nt involve others.

Preston Tucker did this in the late '40s with WW2 helicopter engines , i would use something like a heavy duty Porsche transaxle
