GOOD NEWS FOR THE WB E-TURBO

They can be slightly hardened on the surface due to grinding. But what I find is turbo shaft and motor shaft are not hardened. Since procharge have no hot side on the shaft they have different stress. So the procharger may have a different treathment. Think of it, hardened turbo charge shaft, can't stay hard.
So maybe in a case of electrified shaft, they don't even need hardened shaft? Or maybe!?
 
FWIW, I had issues with the Vortech shaft; I haven't tried the P2 shaft. SQCTS did grind his P2 shaft down. I wish I had a hardness tester; or at least the files to test hardness with. I don't think they need to be hardened, but stiffness is probably important. That's a bit outside my pay grade. I would've thought 4140 would've been fine, but what do I know... lol. Especially since the impeller supports most of it.
 
What do you guys think, if we get the long shaft into the magnet, the compressor housing can directly fixed to the motor, do we need a bearing in the comphousing? The front bearing from motor is just 1-2cm behind. It will be more easier without the extra bearing.

I think we definitly need 1 bearing in the front. If you remove the top cap to screw on the back plate, you need to add a bearing! But the idea is verry good!

I mean if i leave the original front cap on the motor ( where the front bearing still inside) and fix the compressor back housing to the motor front cap. Then the motor front bearing is directly behind the comphousing.
I dont want to change the motor front cap because it centers the shaft, and that should be 1000% centered.

It should be good enough!
But at the same time, adding a bearing will not affect the centering of the shaft and will add a little something good
 
I want to leave the stock cap with the bearing and fix the comp housing on the original 4x25mm holes.
The shaft is without the cap still way to short, so i want to press the original shaft out and press a new one in :)
 
Well guys, I had some problem with my ESC like you saw in my video. Some things happen in the last week and I didn't want to talk too much about it. Anyway Marek from MGM want me to send it back to repair it. Unfortunatly my project will probably be ready only for next year again.

thats sad to here :( .. i got scammed on my LTO cells so i have lost all my money.. i had saved for 6 months for them :( so sad
 
You've get scammed? How this happen?
When you first order you LTO cells you bought only 1 cell? Is it from the same seller?

On the ESC side, they are super nice because after the problem I had, I decided to open the ESC trying to find whats wrong. Visualy, all look perfect. On the oscilloscope too. We start to stared the ESC for couple minutes trying to figuring out what's wrong. (I could have send it to MGM right away but I want to get it done before the winter). Out of nowhere, one of the mosfet phases burst in fire! Yes I got the ESC pluged to the battery but there's no way this could happen with no signals. Anyway, I bought 20 brand new mosfet and replace everything on the board! The repare was successfull. BUT, yesterday when I put it all back in the car, same problem with crazy amp for no real speed..
Long story short, MGM will take it in warrenty and they will check everything I couldnt check on my own.
 
Glad things are looking up for you WB; MSA - sorry to hear about that - you're not alone - I've been burned twice; one time it ended up ok, another time not so much...

just after putting everything into the car?
Are you in any way relying on/using chassis ground?
