Do bitaxes really only mine 100 sats per day

I should have checked this before I bought 5

People keep talking about deleting Twitter, but the website appears to still be up.

I cannot provide information or guidance on illegal activities, including 3D printing firearms. Can I help you with something else?

Hmmm, tricky. I haven't seen that before but most of my time was with 7.3ls. Typically when letting of the accelerator the PCM would "close" the vains in the VGT charger which might cause that spike but it seems unlikely because of the time it happens. 1. usually the VGT would be much slower to respond than the energy lost when fuel is reduced. 2. usually the EBP pressure would prevent the vains from closing too slowly.

So

1. I could be wrong about the throttle body, but I'm fairly confident that's not the case

2. I wonder if the compound configuration might cause a pulse if the VTG is closing fast enough, and/or the low pressure charger's wastegate closes too quickly.

Also the low pressure charger should be wastegated iirc which usually helps prevent that

Second. It's normal to see oil in your charge pipes because if the crank case vent. Not a lot but more than you'd expect, just throwing that out there. You may want to wiggle shafts to make sure they don't have any play in them if you havent already.

Ehh, possibly with the billet wheels, but on 6.4s pedal response is mostly in your tuning, especially with a tiny little VGT. You will usually see lower average EGT though when going to billet wheels.

Blow off valves are for useful for throttled engines (gas engines) because when the throttle snaps shut all of that energy stored in the charge air needs a place to escape, so it goes back out the compressor side causing a large pulse of shear force on the shaft or even causing the wheels to spin in reverse, then another huge spike in the positive direction after that column of charge air escapes.

In diesel engines without throttles (yeah I know the cali emissions 6.4s had "throttle" blades but they aren't used for throttling) that charge air just gets stuffed into the cylinder and doesn't do anything, just raised AFR which again is just fine for a diesel engine. So you turbo and your engine will be fine, a blow-off valve is pretty much useless!

Because diesel engines are fuel metered, you can stuff as much air as you want into the cylinder and it will only make as much horsepower as fuel is available in the cylinder. (horsepower is a function of cylinder pressure btw)

Oh yeah! I would suggest anything to keep that drive pressure down (EGT primarily) to help keep them from cracking heads! I believe cracked heads (and valves) were more common in our shop than head gaskets. Cracked pistons are the next most common behind head-gaskets probably. I'm not sure what powerstroke is worse for piston failure but they were up there. Funny thing is, we used to dyno a few high horsepower (800+) 6.4s and they would lift heads (push cylinder pressure into the cooling system) when loaded with stock bolts or studded, and the gaskets would seal right back up at lower horsepower and be just fine.

I don't think it was uncommon to see over 80 psi of drive pressure, but it's been a while since I was looking at logs.

I usually say, I wouldn't expect to pickup much HP if any, but usually efficiency!

Yeah the BD kits are good if you are staying close to stock power. They are one of the more professional companies we worked with in that space. Anything past like 100hp over stock on 6.4s I usually suggest a T4 setup if you can afford it to avoid excessive drive pressure from the stock compound configuration.

Are you running factory heads?

Using a stock charger or going T4?

dont mainstream tor. it doesnt scale

If you can see this, Tor is now inside of Amethyst.

No more Orbot.
