Hey guys I've start to make an other impeller shaft for the new set up. We discuss in the past of other techniques to make for example a 8mm extremely precise hole. I try the endmill on the tool older instead of a boring bar and it's awesome! 1° angle to work with only the tip of 1 tooth of the...

I understand I have the same issue! I'm on the limite of airflow for my engine and I had surge at low rpm in the past

I think you had enough precision in your assembly. The bearing should not fail with a rotational force. Sure you need a lot RPM and thats the difficult part. Maybe you should get an other compressor? There's a lot of chinese compressor for cheap. I currently have a chinese GT35 and I paid 80$...

Well, that's weird. If the impeller weel goes on the motor shaft with no play, there's not suppose to have problem here. How's look the glue? Can you post a picture here to see your set up?

Your motor shaft and impeller have the same diameter?

If you drill your impeller yourself by hand, its probably the problem. The glue and everything is not the main problem. Maybe only for balencing purpose. But if it was me, I would use a milling machine, indicate the wheel to be at 0.000", drill it and ream it. If you use a normal press drill,I...

How do you fixe your impeller to the motor shaft? Because at this speed, even a 0.001" axial tolerance is not enough. This play can easily break you motor bearing.

They are electric assist and I really dont know if they are able to run 100% electric for long time and if the motor is able to give all the compressor power by itself.. 100% electric turbo on the market is only torqamp. Phantom and ARC superchargers have stop making it.

I will take a step back and try to run this motor safely instead of max out like the other! I will take my time to look at the temperature and make a proper heat sink for it!

I talk to the castle creations team and the motor will be back in stock in the end of septembre 😰 thats way too far for me.. I will ask a refund and buy from an other seller who have it in stock!

Happy to see you! Welcome back 😁

We bought a lot of chinese product and it's scary!one day, something will break because I can't imagine a world where you can make and buy stuff super cheap and still be where we are... Anyway! I will put my stuff back all together when I will receive my motor! It was out of stock and I don't...

I look through a lot of seller on alibaba. Since the gt35 is the most replicated turbo on the market, they made a tons on billet impeller. The sad story is the gt35 have 2 variant. I first wanted a 11-0 blades instead of 6-6. They have a lot of 11-0 blades but for the other variant. The only...

just receive my billet impeller for 65$ Still waiting on my castle motor to be ship

OMG 😰 not fun to see this 😥 do you want to stay with a VESC or go with a quality ESC?

More cells mean less Amps so it's easier for the ESC. The SCM series is less powerfull than the CM series. I would recommand to use a CM version. Honnestly I really think you should go with a bigger motor! The Castle 1721 is rated at 90k rpm and it's a pretty strong and powerfull motor! I think...

I will try an other steel material for my shaft! But I will keep the same concept

Voltage x Amps = Watts If we think Alex need over 20k watts and I need arround 12k watts. I can assume your little turbo need arround 10k watts maybe less

Like I said, the load on the motor is a huge factor. My motor said 75k RPM but I run it safely at 50k RPM at 9000watts. There's no way the dyson motor will be able to maintain his 120k RPM. Do you watch the bench test of Alex with his belt driven unit? What we learn his efficiency of the motor...

With no load on the motor. Probably. But its a different story with loads on the motor! The fastest I spine mine is 63k rpm on HUGE power. I hope I can get the same RPM easier with my new castle motor that I ordered. But I really don't think it's possible. Since its a smaller turbo you probably...
