Could someone enlighten me? I sent a PM to them and called the shop today but they were not in.......

Same question.

And how much trouble is it to install when compared with the ratchet strap method of twisting the Injection Pump?

I was just wonderin the same thing, I've heard a little about them lately but don't know what it is or how it works?

It allows the timing device piston to have a farther range of travel

blackfordd

Um, okay. Didn't know there was a "timing device piston". So what is "dynamic" about this setup?

twichit

it involves the ksb , from what i under stand it allows the ksb more room to travel in its bore allowing it to fruther advance the timing ,kind of like bumpping the timing a tooth or shoving the pump to the head whatever you prefer ........i think

If you have the time there is a ton of info here.

Also a mess of gobbledegook.

I read the entire thread and still have the same basic questions:
1. How does the M&H timing spacer work?
2. How difficult is it to install?

And that thread even added a question:
3. What is the difference in "dynamic timing" and "static timing"?

It lets a timing advance piston in the ksb travel farther letting it add more timing....

"under 30 minutes to install"

i believe the best way to define dynamic timing is varying timing throughout the engine operating speed range.... maybe not perfect but it gets you an idea.

#2 "remove the ksb, put in the spring shim under the existing shim, slip in the spacer with the new o-rings and bolt it back up."

From what I have heard it is supposed to give you better timing across the board. Little advanced for low end grunt and more advance for high rpm.

Ahh, like variable timing on the newer computer-controlled engines. Very nice, very nice. That's smart engineering right there, if it works. Anyone have one? Trooperthorn, you seem to be a strong advocate. Are you running one of these, and if so what did it do for you?

wannadiesel

Dynamic timing: The VE pump has a variable timing device that advances timing as RPM increases. The shim that M&H offers increases the range of that timing device. This can allow you to run less base timing (what you have at idle) and still have the same amount of total timing (what you have at 2000 RPM), or you can use it to add more timing advance without moving the pump or jumping the gear a tooth.

See post 10 for the install.

So i may need one of these to increase my chances of getting my truck to run 12's with the getrag? Will it increase top end horse power to get me to my goal? Of course I still need alot of other work to get there. LOL

There's also a thread on 1stgen.org about it. A guy dynoed with it, and it seemed to have the same effect as rotating the pump.
