Co2 Powered Scaled '29 Ford Roadster
 

This is another one of my projects.

Very cool! :beerchug:

Thanks ACecil.

Test Run
 

so whats the purpose of this? how long is the run time?

Racing and Show. Setup to run 1/4 - 1/2 mile.

cool, i just wasn't sure what this was built for.

It is very kool! I had the same question and also wondered where do you put the babe?......Now I know, in the grand stands.:biggrin2:

Cub Cadet 123

Give a few mores specifics please. First, where did you get the body, was it off an amusement park ride? Is this the chassis that came with the body or something you modified/built? How much pressure are those tanks holdng when full? I'm not familiar with using CO2, could you have used compressed air instead? Certainly an interesting set-up!

You build some seriously cool toys!

John,
It uses liquid Co2 and Nitrogen.It would run on compressed air but there's not enough storage for it to run long.It uses a series of valves and solenoids which are regulated at 150/250 and 350 psi. The body and chassis are all handmade and fabricated by me.I fabricated the grille from flat aluminum plate.Took me ten years to build.The body started out life as liquid fiberglass in a can.No molds,All sculpted by hand.I machined and made the motor and air valve components from scratch.It has two air tanks for the Co2 to expand before going into the drive motor.It has two 10lbs Liquid Co2 tanks and one 10lb nitrogen tank,The nitrogen helps the Co2 expand faster. It also has and onboard air compressor that drives from the rear axle.It does two things,It can be adjusted up to 375psi and used to assist the Co2 to the air motor when at high speed and can be used as a braking system also if needed.

Thanks for the specifics. I've seen stuff guys have made with fiberglass before, I just don't have the skill or the patience! Only thing I would have done different would be to use a gas engine so it could be ridden a LOT. I understand you wanted to do something way different with the drive system.
You've certainly got a lot of time invested in this machine, show it off and enjoy it!

That is one of the coolest things I have ever seen!! Do you have an estimated date you wanna have it on the track by? Would love to see it in action!

You're welcome John.The fiberglass was bad.I'm itching just thinking about it.Notice the seat area,It fits me like a glove.Also,It is built to where it can be converted over to a gas engine.I built the mounts and conversion parts for gas engine while doing everything else.

Thanks John. I appreciate your comments.Glad you like it. I like to build things a little different than the norm. I did a little testing with it this past year.Still working on a few things. Hoping to have time this winter to do some more to it and run it next spring or summer.

Hows it do in quarter? Whats it weigh?

Why would you run a compressor off the rear axle? You are robbing power from your main drive. Same reason what drag cars frequently don't run any engine accessories (no alternator, water pump, power steering, etc.) Just seems like you're holding yourself back.

John, I haven't had it on the track yet and haven't weighed it.

The compressor can be ran at high speeds but will mainly be ran during shutdown on the long tracks to refill the tanks and used for secondary braking by restricting the flow off air if the hydraulic brakes should fail.
