Problem is the web site which the original image is hosted. I just copied it and put it on my server and posted it that way. I'd use a different image server. It's the type of image gallery it is.

What is it going to cost to have a 11hv built to take 1400 to 1800 amps for 1/4 mile? Force air cooling should be easy but it's the parts inside I can't find jack on.

Just the cost of a stock motor. No problem.

At what voltage?

Wait, are you saying its costs 3700$ to build up the warp11hv? Really?

Think he is saying a factory one will take that power burst?

My understanding is that the motor should take 1400a @ 288v for short periods like drag runs without much problem. As long as you find ways to dissipate the heat you should be okay.

Bowser and I were talking about the fact that when we first got info on the 11hv it was rated just over 300v, cant remember the exact spec though. I believe for reliability sake it was de-rated. Keeping the armature from grenading itself, stopping brush arching and dissipating heat are all tough problems to solve at high voltages.

And I'll still be able to street drive this as long as I keep my foot out of it for long periods?

Can't say for sure, but I'm banking on it.

Like I told Bowser when he stopped by to check out the build, "It could go like a golf cart, or a rocket I just don't know yet."

In all seriousness though, I'm pretty confident that as long as we can wick the heat away and keep the voltage up, these motors will put out vast amounts of power.

Hang in there another month or two Dustin. I will be posting all of my data once we get the car driving.

Yes, it will take that current no problem for the 1/4 mile. . . although, the current may not stay up there the whole way. John Metric puts 2000 amps into each of his two stock Warp9's (with Helwig brushes) every race. It's all about duration. The warp 9's are like 10 hp continuous or something like that. Short bursts can be significantly higher.

Just make sure you seat the brushes well. Run the motor for several days at low rpm (12 volts, no load)

The best thing you can do wrt heat is to force as much air through it as you can.
