prechambers mods?
3 front holes to .156" rear two and bottom to .125”
Stock (broken) 1985 prechamber on the left and big baller Simpler=Better ported chamber on the right
So I have turned the fuel up (torque capsule) a lot! And also an unknown amount.... My EGTs only max at about 900 so I have much moar room to go I think. Also I might add that I'm making 14-15 psi with my Garrett w/ 60 trim compressor. Inter cooler not yet operational and Injection timing max advanced (didn't check what it actually is)
My 300 rips, and my transmission is dying (like most I guess) haha. She will be getting a AX-15 when money permits. Back to the subject though, I have been running this setup since beginning of February and even though Mr. OM616 recommended not to drill the bottom hole, we did anyway haha. Just on the fact that we were going for broke, kinda. I didn't want to stay too safe and have to pull, drill, ream, deburr, twice. My OM617 runs flawlessly!!!! I've been to the desert where I've been up hills that $40,000 four wheel drives couldn't make. I've pulled an old broken down F150 10 miles to my shop that research shows weighs about 5000lbs with no issues. It amazes people haha. And it starts cold with a flick of the ignition switch after the glow plugs have been on for 5 seconds.
