Mine did 50psi or boost, and over 70psi of drive pressure often with stock, untouched head bolts, and the pump as close to the head as I could get it without any gasket problems, and I just made sure I had the engine up to temp before beating on it. I have a spacer, but I stripped out the torx heads trying to get them out. I want to pull the pump when I swap transmissions, and get the spacer in, locktite the front seal, cut my 3800 gov spring down, and mod the afc top for better control. Then skip a tooth when I put it back on, and bump my raptor up to 35ish psi.

234(?)k. Not a lie, remember, my head has been done, plus O-rings and studs. I don't do it every day, and I take it easy after that until the truck is warm. And it might be 70 or 80* out too, it depends on the day.

Dman what do you think yours would put out at the wheels in current tune (once paired with tranny of course) :)

So I'm probably ok with a maxed pump stock sticks, spacer and a small bump with good sense being used?

Pete we're pretty close I've got a shade over 220k on mine

Yeah, just let it warm up before you beat on it, it really does help quite a bit. Lots of timing and fuel is the killer when it's cold, it hits hard early and being cold the head and block aren't as tight as they are when it's warn.

I want to say somewhere in the high 300’s. I could see the truck twist pretty good from the drivers seat, so it definitely put decent power down.

Ddp stage 3’s. They’re 55lpm iirc. They run good, but I don’t really want them anymore. I want to get my 5x16’s rebodied, and put them in with a new turbo setup, which means I also want to sell my current compound setup.

Anyone run the MH spacer without the provided shim?

Couldn't find the shim and ran without it, skipped 1 tooth, backed off pump most of the way.

Getting a midrange stutter that cleans up with more throttle. Thinking timing could be ramping up too fast?

So running waste oil/ gas blends the burn is slowed quite a bit as you can imagine. Im going to skip a tooth this winter hopefully.

That being said, Id like to reduce the colorless smoke from oil/ gas @ full operating temp. Its actually not as bad as one would think; provided I keep up to date with the Italian tune ups. But I'd like to regain some rattle.

Q #1: Ive read multiple sources saying much advance ( 1/4" ish and up) actually increases cold engine white smoke. Is this correct and why? I thought the whole idea with the ksb was to cut back cold white smoke? I guess much more timing than whats "ideal for a clean cold idle" starts the other side of the smoke slope?

Q #2: The more advance Ive given the truck so far the more Ive liked it. If my preferable sweet spot ends up being a tooth or more and cold eng smoke gets excessive, is there even any point to have the ksb plugged up? I mean if I was a tooth skipped with the ksb unplugged my static time on a cold eng would still be 3 degrees more advanced than stock time with ksb plugged up.

Hopefully my Q's make some kind of sense

Answer to 1.......who cares about white smoke at cold idle,why tune your engine to be perfect at cold idle. Is the only time you run it at cold idle?

Answer to 2.......your timing will basically top out and it will tell you with a surging motor. I’ve have not noticed any increases in smoke with more timing except at cold start (again....who cares). The engines I’ve put large increases of timing into have all liked it. My Dodge has been running 1 tooth advanced and almost with the pump to the head for years and I work that truck hard (when I run it). My suggestion would be to tune it on straight fuel that way if for some reason you wind up running out of the other you won’t have some negative effects running straight diesel.

I like it. Tune to the far side of advanced on d2 and it should still be more than adequate for oil.

Thanks Ellis :D
