Hi Ian LOL......I think a Lotus 7 would only need a "small" engine like the 10/98 with 150hp capability , the 666 with freepower would be ~500 hp ,the Rover BRM www.sportscars.tv/Newfiles/roverbrm.html only had ~140 hp and went very well with its restricted gearing ,a lightweight chassis with a 150 hp freepowered engine fitted with a modern automatic gearbox would fly :-) Once we get past a couple of hundred horsepower its probably safer and easier to use a time expired commercial shaft engine if its going into a car, the only reason I'm making the 666 is because I already have the parts and it seemed a good idea to use them, and it might end up in a bike one day where its "simplicity" might be advantageous. Cheers John

Hi John, I am sure you are right a 150hp Hyabusa engine in a Westfield is scary enough, just have a look at this one going round the Nurburgring passing super bikes and Porches like they are standing still. www.youtube.com/watch?v=k5VDCKIl7ew Now think 500hp, no engine braking and Mount Panorama..... Chris that would be some "scary shit" Ian...

Hi Ian
LOL......you forgot to mention the "run on" from excess residual heat in the turbine stage when you back off .
A power to weight ratio of ~1,000 hp/ton would be enjoyable on the climb up the mount, but coming down might be another thing...............heh heh , I use to enjoy an early morning ride around the mount on my turbocharged 1,500 cc bike when I lived in Bathurst, that long downhill straight is very tempting, shame about the 60 kph speed limit ;-)
Cheers John

Let's see you do it. There are closed road courses for a reason. You have the reason.

Chrysler made a turbine jet powered car in 1963. The Chrysler Turbine. Anyways they were legal but then destroyed. They are rare and only a few left. Very difficult to find diagrams of the engine design and drivetrain.

A friend of mine made a rather fetching turbine 'hybrid' using a GTP-30, a honking great DC electric motor and a lot of batteries. It's fully UK road-legal and works great but an unbelievable amount of work went into it. Not a project for the faint-hearted: www.jetpower.co.uk/gtcar_phase2_media.htmAnother friend is also doing a turbine car project but direct-drive off a shaft-output engine. I'm not sure if it's super-secret currently (or intended for the road even) so will ask him to come post some details here.

That sounds exactly like what I want to do with the electric motor. I'd have a look at the website but all I can get here at work is a google cached copy of the site.
Any more details on the car would be greatly appreciated.
I was planning to build a test bed with this arrangement on a small (5" Gauge) train so I can get everything working at a smaller scale first.
Cheers, Rex

I'm in the US - Detroit so I can't answer that. However, you would do best to make a hybrid with a regular motor for regular driving. I'd presume regardless of where you are blasting the guy behind you with hot thrust gasses is going to piss him off and you might wind up paying for damages. We hold a huge car show every year along Woodward Avenue and I'd love to show one off out there.

Hi Syler, I'd be looking at a series hybrid style of system, similar to the link cursorkeys posted a few posts back. At this stage I'm thinking about getting my hands on an old APU and using that. The problem there being I don't want to spend more than a few hundred dollars at a time until I finish paying off my new car (Had to replace the one I wrote off) so I probably won't even be looking very hard for nearly 12 months at least. Unless someone happens to know where a cheap APU would be in Aus. Cheers, Rex

Hi John,
I imagine importing wouldn't be too simple/cheap either.
Cheers, Rex

Hi John, I imagine importing wouldn't be too simple/cheap either. Cheers, Rex It's no big deal bringing them in, but I recommend you find a shipping agent to do the paper work. Getting it picked up, shipped and landed in Australia is the easy part. The most expensive part is getting it off the wharf here in Oz.

I used www.sparkgl.com.au/ for importing my GTP70 had no problems. But shop around for a good quote for your import. Cheers, Mark.
