That will make mapping very interesting.

Piggyback control module for ECU and then standalone for the turbo/fuel management too - sounds like a headache.

Makes ya wonder if you could find a way to push that extra fuel in there via pressure from the wastegate as it approached it's preset blow-off er sumthin like that.

Headache? Thats where it gets interesting. Just think mack in the 80's the thought of running a car let alone compleatly on computers was a headache. Now today 2004 would you have it any other way?

Just some trivia... In 1899 yes over 100 years ago, the US patent office gave a statement saying that "everything that could be invented already has been." all i can do is laugh So my point is some new crazy idea, may not be all that crazy after all. As moto man says, "Think Outside the box" yeah it sounds dumb but really does make a lot of sense. Don't change you thinking because of what other people think or think about you. Don't go with the flow, make your own path.

Now for the good stuff!!! about 2 years ago i ran into and idea (not mine) making a Turbine engine AKA Jet Engine out of a Turbo charger. So what did i do? i made one. I was still in high school so i didn't have too much money to spend at the time so i got a used T25 off of ebay. i have some pictures, sounds and video but they are not mine.
*****This first one shows the main section itself NOTE the cap over the compressor to keep stuff out wail not running.*****

This next one os called the Flame tube which sits inside the combustion chamber. It has a fuel injector similar to diesel without the extremely high pressure and a spark plug or something similar. the holes are to let air in and out without blow out the fame which is constant once the engine is started.

Here are some sounds and on video link just so you can get an idea...

Idle http://www.nickhaddock.co.uk/t...e.mpg

short Video http://www.nickhaddock.co.uk/t...e.mpg

Now that you have basic understanding on how a turbine engine works ill tell you more on mine <U>KEEP IN MIND THAT THIS IS ON TOPIC I JUST NEED TO EXPLAIN ALL THIS FIRST</U>

I used propane to fuel mine and Vaporized diesel for that afterburner which this onedoesnt have. i got a fuel pimp putting out only about 25 Psi through a coper tube, the tube was wrapped around exhaust pipe about 5 times or so. a hole is drilled in the exhaust pipe and one end of the coper hose is inserted in. now in the end result what this does is, the heat from the exhaust being extremely high heats the diesel is vaporized like steam and water. but don't worry the diesel WILL NOT ignite until its out of the coper tube, because the is no O2 in the coper tube. when the diesel ignites there are no words that can describe it... OMFG!!! 5 foot torch shooting out the back not flame the pressure shoots through the roof.
this pick is without an afterburner so you can just imagine


I hope you were enlightened on this and want to put 4 of these on your bike lol

Gotcha

Whoa dude!

the idea of anti lag is to increase exhaust pressure thus spooling up the turbo quicker. Im sure you have herd of an afterburner on a jet. an afterburner basicly injects fuel into the exhaust which is ignighted by the exhaust inturn GREATLY increasing the exhaust preasure.

I know this is going to sound crazy but one day... to do this on a internal combustion engine, you would basicly inject fuel into the exhaust manfold that would automaticly ignight being so close to the exhaust ports. the problem with this is that there isnt much O2 left to burn the fuel so ither the engine would need to be set very lean for a short period of time wial the anti lag accures or an oxidizer would need to be introduced which would increase the danger.

So i guess all in all for every pro theres a con and one day some lame *** guy will take this idea (which wasnt mine to begine with), refine it and make millions lol</TD></TR></TABLE>

this is definitely overkill.

the turbo - turbine conversion is pimp though. i'd love to make one if i had the free time. but i dont.

So if ya used a compressed oxidant then you could also use that to cool the intake charge too - right?

Lotsa cool stuff there - WOW!

I feel like it will be easier. I already have a greddy rebic, which is pretty much a
standalone unit. I will be able to leave the stock wiring harness and computer
intact, which means i dont have to worry about things such as the gauge cluster.
The rebic is fairly simple, the only imputs being: pressure, injector signal, rpm
and power. It should be all i need to keep it nice and rich under boost.
The only thing missing is ignition retard. Initially i will just do a static retard on
the power commander, which is already installed.

I will more than likely just end up switching over to the standalone, but i dont
feel like having to tune completely from scratch right off the bat.

I'd love to try this one day. Probably will never get the chance, try to keep us updated on the project!

And you guys posting about tubine jet conversions and anti-lag contraptions... double U tea F?

Double U tea F?
what is that???

this post about anti lag, is cool and all but it has already been done to an internal combustion engine. its called a missfiring system. its is used to keep the turbo at constant spool so there is no lag. its used on WRC cars. if u watch them when they sit at the start and they rev the car constantly backfires. and when they downshift of let of the gas same thing. the rpms will drop bu the turbo is never out of boost range.

Damn you beat me to it.

There was a great write up about this in Racecar Engineering a while back. Basically as Shabadoo explained in his previous post in the general idea about raw fuel in the turbine manifold.

The car is full boost at idle. ZERO lag. If anyone has ever listened to a WRC car at the line idling and revving up they sound like dog ****. That's why.

And you'd better live close to yer tuner too.

Yer better off just sellin the bike and buyin a litre bike (or larger).</TD></TR></TABLE>

wow .. alot of money. Top of the line Honda (cars, not bikes) for for $5-6 .. those are with $1000 turbos. Bikes will be WAY cheaper ... it's the same thing, just a smaller, much cheaper turbo and a different manifold. I can make a junkyard kit for a honda for $1000 or less, and i'm sure i could do the same for a bike.

In my opinion, it would be really time consuming, but the money wouldn't be too bad.
