Was reading an old service manual and saw something wild about injector pressures

I was flipping through a 1990s Detroit Diesel manual for a Series 60 engine. On page 47, it said the injector firing pressure could hit over 30,000 psi. I always knew it was high, but seeing that exact number written down made it click. That's more pressure than in some industrial hydraulic presses. Makes you respect those tiny seals a lot more. Has anyone else come across a spec that just seemed crazy high?

My $75 rock hammer purchase was the best and worst decision I ever made for my collection

I used to cut all my dados with a router jig, but after a kitchen job in Spokane, I switched to the table saw for good.

Skipping my pre-work stretches for a carpet job gave me a nasty back strain and set me back two days
