Kind of a special question that has ben floating on my mind... Is that illegal to use a locomotive's alternator/generator (Call it what you want, basicly the big alternator from the train itself) . Running from a transaxle form the engine of the truck back to the generator itself it could produce a sizeable amound of current fairly easy.

Im asking this question because in the officials DB Drag rules, it's no where mentionned how many alternators we can put in a car, not to mention what kind of alternators that we can put. However, i know it's mentionned that the system must be powered by the engine's power, so no external generators are allowed (Like big Cummins 15 kW diesel generator....)

Thanks (Remember that's only a wild idea, don't try this at home :-)

Dude, do you have ANY idea at what voltage a locomotive Generator runs at??
let's put it this way, each wheel motor is 1000HP, ok so that's 6000HP of electricity (or, 4,476,000 watts)

now these are 600 Volt motors. There's 6/0 cable run to each one.

not to mention the fact that one of these generators probably weighs MORE than the vehile you intend to put it in.

I'd say get the thought out of your mind, it will not work.

oh, and ps.

there are three generators in most locomotives, they're a succesive system, where the first one is used to power up the second generator, the second one runs the trains electronics and fires up the third one which is what supplies current to drive the train.

also the 16 cylinder engines that power these generators produce over 2000 lb-ft of torque at 900 RPM, and they redline at 1000. I don't think you're going to have the power to even run this system.

I know the power requirements for such generator! My general idea was to find the best way to produce energy... Not to install this into my VW... :-)

Remember that my original question is: Is it legal or not to have that kind of equipement, regardeless of the size factor...

:-)

leece nevile make alternators for ambulances that put out a true 160 amps and above unlike some other alternators that a car stereo shop would reccomend (i know this because my dads alternator shop gets people in all the time that got "stung" into buying "gumby gold" and other crappy alternators only to have many problems and spent way too much on them to begin with.
i have a 2000 s10 that we are going to put a 160amp alt in and if it works ok maybe we'll offer it on here, if anybody is interested let me know

6/0 gauge wire does not exist, after 4/0 it becomes MCM

250 then 350 then ...

Oh, and the generator in a locomotive weighs a few tonnes, neither you nor anyone you know would be able to install it. If you are talking about the little alternators on a locomotive engine, those are about 60A and are for instrumentation
