Ok, I also ordered the 4 pin from mouser (hasn't gotten here yet) but I couldn't find the 2 pin. The "techs" there didn't seem to be able to help either.

I got em from mouser, was a ton of fun researching the right crap, you can't just do a visual even though you know the manufacturer. If you're looking for part numbers once I have it mounted and running in my truck I'll update my thread with a BOM

I've got the VR circuit on and working, just can't find anything to spin the turbo fast enough to verify circuitry since its low voltage at ~1200rpm.

Anyone local to you have a VSR balancing machine for turbochargers? These machines use compressed air to spin the rotating assembly at full operating speeds to check balance thru vibration on an assembled CHRA. The turbo is supplied oil and can be cycled numerous times on such a machine...it's almost like a dyno for a turbo but checks balance instead of performance.

I'm not sure sure of any other way you could do much bench testing without the turbo being mounted to a vehicle.

The vsr cabinets I've seen have the turbine encased. So you wouldn't be able to see the it go through it motions. I doubt the pieces I've seen were newer generation machines though. I know there are quite a few manufacturers and even bench top models now. They may apply the air to the turbo Ina different way.

It's 3 pins for the vr sensor, 1 is plugged, that'll help you narrow it down, I believe it is an AMP connector.

I got a 24v fishing reel setup, I might try using that to spin the shaft see if I can get anything out of it.

BTW, verified with the speedo reel setup, it is a VR sensor.

I also got the ring made today, and it fits like a glove, sanded it down and used a hand mallet to press it in.

Wow, great thread, wish I hadn't sold mine now, it was literally brand new.

Haha awesome. I'd love to see a video of the fishing reel turbo dyno. Very hakcentric thinking, hakcenter.

Thanks, I'll keep looking for it on Mouser.

@maximum9898 , any information you can share? Are you keeping it secret for some reason?

Has anyone seen dyno graph of HE351VE, so we could decided whether it's low-rpm spool is really much better? Or maybe first-hand experience

Video does a good job of showing that, yes you literally can spool it immediately. My project is going very well on my truck. Just so you know, I have the controller setup for idle control, so once shaft speed is under what I consider idle, it goes into full open and waits. Once shaft speed is past idle, it starts to close veins, up to a specific shaft speed, then starts to open again after that, so it looks like lag on my truck, but rest assured... I can make it spool just idling with it fully closed.

While unfortunately I don't have any dyno numbers, my personal ass dyno tells me I've got substantial momentum where I had none before. My truck actually delivers power in 2nd gear, where as before nothing. 3rd gear rides like a raped ape, and 4th / 5th gear is just trolol gears to people that think they are fast.

I hadn't changed any tune on my truck, except actually taking out fuel, which I did after about a week of tuning this turbo. And since day 1 mapping speeds out, the smoke my truck generated almost completely disappeared in all mid ranges, which IMHO is where this turbo excels.

After the last few days, I've made an automatic cruise mode, that seems to work pretty well, if I had more variables to work with than just shaft speed on my truck, like a TPS, or something it would be a lot easier to create that kind of code, but overall this turbo is just a monster.

I couldn't imagine anyone actually getting the top end power, that I am making, without actually using an electronic controller. I am up to 5 stages for top end, and 4 were absolutely necessary, I added a 5th because I wanted to get to maximum open on the turbo to see if the shaft speed ever slowed down in a long pull (which for the time being it isn't).

I couldn't imagine just off of back pressure / mechanically controlling this turbo, to get any kind of top end like what I'm getting out controlling it normally through the electronics.
