Nope no Facebook here.

What's the rated pop pressure supposed to be?

325 bar is what you can set them to.. so that's a considerable bump

I like that.  I am wanting to get a set at 340 bar for testing how well I can atomize while keeping it driveable

What are the 24V injectors usually set at? I think 12V  P pump ones are usually around 285?

hmm.. so the H pump on a 24V should work nicely

Well, I went to the drag races yesterday again.. I beat my best from last year by 1/100th of a second, but MPH was a little slower.. 10.02 @ 72mph.. I attribute that to the extra shift I needed with the 6 speed..
I blew the 5th gear shift 3 times, that short throw shifter is sooo sensitive you just THINK of the gear you want to go to and you've gone too far.

Didn't get much for video, but here's the burnout competition.. I didn't get anything, but the tires were at the very end of their life anyhow, so might as well have some fun

I told the pit guy to stop me if I was smoking the clutch.. I started in 3rd gear, and he say "you're good".. I killed it thinking it wasn't working.. so then I didn't want to restart another time since the tires had gotten sticky, so I just did it in 2nd.. tire speed was way down so took a while to smoke, but I had fun brapping the throttle, and the truck looked good doing it

Oh, I also hadn't looked at my program in AGES.. I had some bugs to work out of it that I never got to fixing.. it's working better now, and my display will show what mode it's in.. brake mode, staging, burnout, etc

I'm still having a problem with what I assume is the I2C preventing interrupts from being caught and making my engine speed erratic.. have yet to figure that out..
Once I get my daughterboxes built I will just transfer everything over CAN and have faster processors which will make both the wiring and the coding simpler.. one box for display and manual inputs, one box for "thinking", and one or two in the engine bay that collect data and control outputs.

Looked great dude. How are you catching engine speed ? You may want to disable the interrupt during the math section of using that variable.. that's all I did.

The engine and turbine interrupt handlers are very short, just "count++;".. Then every so often I check for how many counts have elapsed, and only briefly disable them to copy to a temporary variable... I never noticed this when I had it displaying over serial, it started when I enabled the LCD

I pulled the trigger!!
67mm turbine wheel and 67mm compressor are coming in... I look forward to lowering my drive pressures, I think that'll make a huge difference at the top end

Well, on my drive to Kamloops (100 miles each way) yesterday with a load of calves, my #2 injector stuck on me.. I think it stuck open first, smoked like the truck was starting at -20, then it cleared up and ran well, then started acting up again and missing, but not so much smoke... cracked the injector lines, #2 was dead, pulled it and took it apart and the pintle was seized solid.. with a bit of fiddling I got it to come out, it was galled.. I had some steel wool with me and I cleaned it off good, put it back in, still misfired badly.. Limped home, will be swapping out to my old injectors (found out they're 4x013 155* VCO).

Considering how much the 4x013s compressed the spring when you took them apart, and how little the 5x012 did, I'm wondering if the spring isn't bad.. perhaps broken? I'll take it apart and inspect it.

They're out of warranty but the vendor will be looking at what they can do for me.. we'll see.

Oh, I also got the turbine housing machined out for the new turbine shaft.. compressor will be a bit more of a challenge.. waiting for the parts before I tackle that side of it.

67x76 blade ? Pretty sure you can't go any larger than 70mm on the outer because of the vanes

I'm pretty sure the BAE is a drop in,
