pulse jet powerd turbo

[majic79]

i love this forum already guys haha. to think what ive sugested in the past and got laughed at for. you guys are realy thinking o utside the box

I think it might be because the first thing we do is take everything out the box when it arrives. Then perhaps taking it all apart to see how it works as thats a good idea too

And then going - what happens when you put this part from that box of bits that we dismantled two years ago into this new fangled thing ... BOOM

I forget the name of the company, but they were around in the 60's/70's, and they basically made a couple of jet-powered parts....

a turbo, with the exhaust side powered by their own jet-fuel. Press a button - 40-50psi of boost on demand


or their awesome add-on, a live rear axle, with a 1000Bhp jet attatched to it. It's geared for your engines maximum rpm (so your engine won't suddenly try to do 12,000rpm!) and is permanently attatched to diff, so it's always turning. Again, flick a switch, and BOOM! Instant accelleration, with no engine mods needed!

I would LOVE to have something like this on my scimitar... 250ft/lbs of torque from my diesel, and 1000ft/lbs from the 2nd engine

aha!

Turbonique!!

C'mon guys! There was one of these in PPC a while back. It may be a few years back actually

I refer you to my first post in this thread - it was a year or so back when you were doing the strange engines article if my (failing) memory recalls...

I'll have a look at back issues, I couldn't remember the name of the company, but AvPin is the name of the stuff it uses (chemical name Isopropyl Nitrate and also called Thermolene by Turbonique)

Heard many a story about this stuff, including an old boy trying to start his alfa on it - when it caught and ran, he couldn't shut it off, it revved to the max and was suffering badly before it ran out of fuel - apparently it ran fine after that!

Looks like a standard Jap exhaust to me.


I wonder if one could be made for £999?

It would be Tax exempt as I'd re-register it as a hybrid.

Its a shame but I can't find any videos of this thing running. It still exists and was recently sold at auction. It would have been good if Jay Leno had bought it because he would have sent it up the strip with the rocket motor burning. Just search Youtube for ''Tobacco King Rocket Car'' and you'll see it going to auction.

Its the same theory Sammy Miller used on Vanishing point to go so fast the NHRA banned him from running full mast. Santa Pod like a lunatic of that calibre so they sent him down the quarter in the early eighties to acheive a 3.81 and 350mph at a time when Top Fuel could only just manage to make the 5's.

thought i would give this thread a little bump as it has been on my mind again.

I did find an article on a hill climb car that used a helicopter turbine to power a turbo (no lag) and apparantly it was epicly quick.

It ran off a seperate fuel supply so would only be good for sprints and hill climbs but still epicly cool!

temperatures on the turbo must get pretty high exhaust side im guessing unless you can somehow cool the exhaust charge coming out and just purely use the thrust (i have no real experience in this area)

Is there a small package turbine which would produce enough force to spin up a reasonable sized turbo?

That one?

There's a few turbine powered drag cars around.

Use a gas turbine to drive a shaft that drives the wheels, simples. Throttle response is terrible (put at full power, hold clutch off... wait for green light, release clutch and go!), but with a variable speed electric drive and an electrical generator on the back of the turbine, you should be able to do something useful with it

What's even better, I've got some plans for a US army emergency generator based off an alternator and 3 turbos - twin stage gas turbine and the third turbo's turbine extracts energy to drive an alternator - might be able to make something small enough to fit on a kart
