Dyno testing 'performance mods'

[robe]

I was mining crypto for a few years and it made so much heat I only needed to light a fire every couple days. Who has an electric heater that makes a return?
I still have a few rigs, I'm going to fire up a couple again but the return is break even at best. I don't miss the big electricity bills but really keeps the house warm.

Hey @WillitBoost can you get me a measurement of the stud spacing on your bt100

 

[WillitBoost]

Yup, it was posted here a couple of weeks ago with the exhaust measurements. I'll check it again for u in 10

Awesome, thank you

55mm stud spacing on the BT case.

~page 76 thereabouts for the dimensions

Thank you!

We started a group chat a few days ago over on the BYP FB group asking for your max speed, requiring GPS or video proof along with build specs. There's some pretty impressive speeds but it looks like a modern china doll, with very little effort, mods or cost can achieve 45-50mph, almost out of the box.

They've certainly come a long in quality and performance. And definitely raised the bar on what I'd consider cheap performance.

I'm about to dyno test & record the advancing or retarding of the magnet using a stock magnet, key and keyway. It's probably only 6-7degrees worth of play but should be interesting to get some numbers behind it.

My 3 cheap Amazon CG motors all from different outfits have been pretty nice over all. They all came with allen head bolts and two came with BoFeng carbs. Only one was a bit sketchy with a loose wrist pin, that I replaced and an old NT carb with the float tickler.
I bought these late winter of 2023.

One came with a one piece jug that looks promising, haven't tried it yet. I didn't order this, ya get what you get.
These kits were all around 150 CDN each.

Ok I've read this whole thread can you maybe list what each part you have on and are testing, each dyno test and post what parts and tweaks are truly adding hp. It got a little confusing having to read 126 pages of this. Lol if not its ok.
