no joke, I bought one the other day to see if this was a real deal, it showed up today, and well it's real! it's obvi not a real BW turbo seems some kind of rice knockoff but, for me to make an electric turbo for my 75cc Tomos it's perfect. The wastegate controller is in cherman. Better than that $100-200 crap you see on the jungle site. This turbo use code SHOCK20 for $20 beans off. I just ordered two more! it looks like supplies are limited. it looks like its shipping from https://www.tucker.com/ but I can't find it on their site

Now, can someone machine a couple for me?
 
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 be able to run higher RPM with gear or pulley. But again, you can't put infinite pulley because you don't have infinite power.
 
scroll to the last page of this for the compressor map. 80-90k is in the sweet spot and way more boost than ill need. What about a Dyson vacuum cleaner motor? They do 120k or more. I must be able to find a motor.
 
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 is the key. He change the pulley to increase his RPM but instead it run even less RPM than his last one. Why? Because BLDC love to run on efficiency. Too much load will insanely reduce the RPM. Too much load means more boost or too much torq. Your Dyson motor will run 120k RPM free with nothing on it, but I can bet that I can stop it with my finger. Now imagine trying to stop my set up or the alex set up with your hand, you will probably miss some finger.
For an other story, we conclued with @AlexLTDLX that loosing finger can pay well. Like 5000$ for a finger I think HAHAHA
Joke aside..
We don't know all on this, but we learn a lot of stuff and we can guide you with all of it.

lol... How much torque or watts do you think I would need to spool a small compressor? I found these guys www.koford.com
 
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
 
WB - I think our results are a little skewed because I think we're both in the choke part of the map - I know for sure I am. It took less than 14kW to get to ~650 hp and now it's taking 33kW to get to ~722 hp - hopefully meth injection will help a bit with that. FWIW, I was trying to find a compressor map for that turbo, but haven't had any luck. I did find out it's a turbo for a 2001-2005 Porsche 911; the OEM part number (on the original link) is 996_123_983_72. If either of you find a compressor map, I'd love to see it.

I found OEM part nnumbers996.123.984.72 and 71, BW part numbers 5324 988 7006, and 7005. I found this check pages 23,24 and the last page. I was looking at the compressor map on the last page to guesstimate. From what I see L and R side Turbo model numbers are K16-6726 + K16-6727. on page 25, it also references model spec BV50-2277. I contact BW directly asking for a compressor map but have not heard back. I finally found this BV50-2280DCB426.10BVAX0 from here.

@AlexLTDLX @WB projects, what do you guys think of the TP power TP 3640-SCM series. What is the difference in getting 2s,4s, and 6s if they all make the same power and RPM? High KV = better?

I was thinking of using a motor mount like these these and using gearing. If I were to gear it I should probably go for a more powerful motor with less RPM.
 
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 you maybe should go with something like this because is clost to your RPM and for sure the motor will support all you need if you gear it!
 
I agree with WB - more voltage is better (up to a point) - you get less current draw, less cable-related voltage drop, etc. I would encourage you to try to stay away from a gear box - not that it's impossible, it's just very difficult to make work at these speeds reliably. I'm discovering a heat issue with the belt drive unit that I didn't think would be a problem - all because of the speeds we need to run at. Again, it's not impossible, but it's not easy. Direct drive is a better way to go in my opinion.
 
@AlexLTDLX What do you think of TP power TP 3640-SCM series for my application? 1400 W continuous and 3000W max peak for 10 seconds? I forget what you said in your video about how long you run yours. Is it the whole 1/4 mile?
 
Yes, the whole 1/4 mile. I think for your application, you should see some significant performance improvement - assuming you can jet it for boost.
