Did it run off of batery(electric) or was it just there to cause more pressure and how did the car like it??

That's from what I remember about that post.

yes bushings.. it was a hobby motor for one of those airplanes.. They use carbon bushings for DC contact. If you decide on doing this buy an inverter and use a pulsating fan, aka brushless fan.

an electric motor can have bushings for the armature shaft to spin in instead of bearings, usually brass-based bronze, bronze silicon, bronze phosphor or "oilite" but bushings/brushes are not an interchangeable term in the electric motor. Brushes are almost always pressed carbon powder, soft and to deliver +/- power to an armature commutator while bushings are guides that maintain armature axis alignment and concentric rotation of armature shaft between two magnets and allow it to spin freely within a low-friction, non-abrasive housing at each end of the armature shaft.

I can find no reference of bushings being called brushes in any of my electric motor catalogs and no reference of brushes to be used as any type of low-friction bushing or bearing surface.

All across the board a brush is a brush and a bushing is a bushing and they are not the same, similar, identical or interchangeable in any reference or application to electric motors.

And i am SO sorry that this is the terminology that i am use to. No need to bash it out the window.

Although, I do know the difference between brushes and bushings. ;-)

but not after each run. I do track events, and some times one or two other drivers share my car. 30-40 minute sessions, times 3 - 4 sessions a day, times 1 or 2 or 3 drivers, times how many wide open throttle events = motors running all the time.

They would last maybe 2 to 4 track days (again depending on how many drivers). For daily driving, it is definetely much longer. In fact my friend's Maxima, he just took it out after 4 years to sell his car, and the motor still has good life in it. He's never touched it.

It's good as an interim item, but if you drive your car hard, it's not going to take the abuse very long. Brushes were cheap. Eventually the housings cracked and the commutators wore out. One of them still works well. Epoxy fixes the cracks at times :P<ul><li><a href="http://www2.towerhobbies.com/cgi-bin/wti0001p?&amp;I=LX3593&amp;P=7">like these</a></li></ul>

What do you think about just putting a small propeller inside the MAF housing that would just be powered by air being sucked in from the motor? Would it flow more air in? The reason I am asking is because somebody was trying to convince me that just a propeler in the housing would produce more air coming in, I just can't get it how is that possible??
