I have an idea for a turbo... - Page 3

You'd most likely need a bigger body.

Uhm, no: turbo=turbine powered device generating pressure.

You would need to make sure this "generator" would not get a reverse feed from the batteries and become a motor. The parasitic losses from the generator would cancel out any power gain. It would be a useless novelty but you could get rich selling it to idiots on ebay. That gives me an idea but i'm against the step on people to make money logic.

ok i now understand the whole idea... first you will have the stock motor that is powered by the car, the second motor will actually be a gear driven genorator (the turbo) and the turbo will be wired (with diodes preventing the cars power having to power both motors) to the stock motor... so in essence as the stock motor goes faster, the drivetrain will go faster, so the generator's gear will go faster, so the generator will make more electricity, sending more voltage to the stock motor, give you you more voltage (power) as revs increase (like the real thing in electric form)... GENIOUS

btw has anyone seen the Eclipse Concept E its sexy, V6 270HP AWD with E-boost technology. what that is is like electric nitrous, its a 200hp motor sinked to the rear axel, so when you hit the button the motor and engine work togther to make 470HP!!! and it also has 6spd manual, with automatic overide (press a button and the car will shift like auto) comes out in 06 (my graduation present hehe)

Car and Driver only said that it was a concept - I don't think Mitsubishi is going to get away with selling it like that, it looks like a space-travel machine. The front might make it to production, they said, but they're skeptical about the rest.

Solder the Mini-Z FET Turbo on.
Simple solution.

as for the turbo, they dont want an increase in fet power, its rather to emulate the acutal effect of a turbo, were their is more power given to the motor as revs increas, btw i read that the elcipse will apear that car i talked about, but no side pipes, no 20 in wheels rather 18s and no e-boost, not bad a twin turbo upgrade and you'll own the streets

im starting to like this idea, im gunna go to the shack and pick up four diodes, them im gunna use two 2.2 ZZ motors as turbos, wire them to the xmod motor using the diodes so that batt energy dosent power the ZZmotors, obviously ill have to use a rubberband to tie it together but i think it will work... however will the two ZZ motors make enough power to have any effect on the xmod motor?...

I am sure it will prouduce more drag than energy.

The best way to test the motor output is, once you have it hooked up place a volt meter on the "Turbo" motor and run the car at full speed (While the wheels do not touch anything). See what the volt meter says.

spitty12 · #38 01-09-2004, 01:18 PM

This won't work, the drag on the motor will cancel out the power from the generator. So this would be a lot of work for nothing.

If you want to relate this to a form of forced induction it would be a super charger due to the linear power response(the power that you won't be getting)

I was curious to see what the little bit charge/zip zap motors would put out in terms of power so i jammed the pinion into my dremel and let it spin while having a voltmeter connected. Be careful if you do this since I had motors flying at me if i went above setting 4. I was using a 2.0 motor and a stock clone motor and the results were the same, I never got a steady reading since the voltmeter was fluctuating about +/-.02 volts

Dremel setting 3 out of 7: .28 volts

Setting 4.5 out of 7: .39 volts

Not sure what rpm the dremel was running at but it is an older model from the early 90's and was spinning so fast the motors flew across the room when the speed was up.

xxspeednplayaxx · #39 01-09-2004, 04:21 PM

o well, yea i knew about the drag which is why i thought ZZ motors but obviously theirs not enough power in them... one question that ive had was, what if you placed a 9 volt (wired in series) from the red wire coming from the plug, to the motor itsself, wouldnt that give the motor an extra nine volts, and leave th pcd alone?

now this guy finally inderstand what i have been talking about. And i almost having it working. i am constructing and adding the trubo right now. it's under construction, but should be finished soon. And to reduce the drag you have to have a second motor with like no torque (since you won't need it anyway) to take away almost all the friction. Luckily i found one that spins so easy. But it will be hooked up and tested soon, probably tonight. I will get back with the results soon

When you get it running and are able to prove it that would be great. The only flaw in the design is that the drag of the motor will be greater than the power generated.

If your theory were to work, then all you would have to do is start 2 huge electric motors running, then eventually you could just fun off of the power that one motor generated to power the other motor. That would be like getting 200% fuel effectiancy.

eetoi · #42 01-16-2004, 12:00 AM

This HAS all been discussed before, the idea simply won't work, as explained in that Alternator post thingy... Which I contributed a great deal to

Look, the closest thing to a Turbo here that might actually work are turbo capacitors, aka the electronic gas tank. I don't know how to wire them, but I do know that the generator thingy won't work...

Yep, you're trying to make a perpetual motion machine...which is impossible.

The "turbo/generator" motor is not going to make any more power than what it is given, ie, the power it is robbing from your "real" motor. If friction and entropy didnt exist, it would run exactly as fast as before. In reality it will just be slower. You can't get energy from nowhere, you can just change its state (mechanical vs electrical)

Now you say "Well, Mr Smartypants, a real turbo makes energy from nowhere and runs off the engine and puts more power back to it. How do you explain that?"

A normal turbo is powered by the fast, hot exaust gas that is shooting out every cars tailpipe. It taps this energy, which is normally wasted, and uses it to force more air/fuel into the engine.

Oh man, theres also a HUGE difference between forcing unburnt fuel into an engine and feeding a motor more electricity, but my fingers are getting tired...

My first thought, is to make sure you use diodes as well, so you don't wind up trying to power both motors in opposite directions! The way your pic is drawn, with power connected between the motors, as soon as you hit the gas, the power would flow to BOTH motors without. As far as gains go, it would depend on just how MUCH that second motor would output from the RPMs of the first.

CharlzO · #45 02-21-2004, 12:49 PM

As for voltage..I just tested an 8000 RPM 1.5-3.0V hobby motor from here at RS with a stock motor in my RSX, holding the gears together and testing, and I was wound out, gaining about 2.7 volts at top RPM in the car. Just an FYI, and I'll keep trying to ses if I can make this work, and get anywhere with it.
