Timing advance

Just thought I'd post this up over here.

A while ago, I got the idea to go ahead and advance the base timing on my VP, in an effort to gain some power, shift my power range upward, and decrease EGT's. Since a timing box can't achieve any total advance, the only way to achieve this is through mechanically advancing the VP timing. I run mine advance 5* or 1 tooth. On the street I have noticed quite a difference, but have yet to do back to back dyno testing, or run a timing light on it.

I now know of 1 other person that has done this as well, and has dynoed before and since. The biggest thing he noticed was that power didn't fall off past 4k with his redline box. I will have more info on this soon hopefully, as Left Coast Diesel has offered to give me a deal doing back to back dyno testing with the set up.

Also I have not thrown any codes so far.

This bumping up the timing by advancing a tooth could end up being another common mod. Kind of like a chip and straight piping is extremely common.

Yeah, I'd really like to see it on a stock truck to see if there is any benefit. I have my doubts about that though. I think it probably only becomes necessary or helpful once some fuel has been added.

I don't know, the little bit of timing a mileage max adds is noticeable and nice.

You turn it clockwise as you are facing the engine. however, we have encountered a minor snag with the IAT sensor (this is not the Intake Air Temp sensor, but an internal sensor in the pump). It reads a TDC mark on the pumps cam, and the ecm references that to the CMP and determines the internal timing advance required. Supposedly the redline box will override this, but it may be a little while before there is a unit developed specifically for over riding it.

Does it really lower the temps? Or does it just keep it in the cylinder rather than in the exhaust where you can see it on the gauge? Food for thought. And advancing the timing on otherwise stock 12v's helps, so why not on a 24v.

We are planning on having the Redline on our 24v but does that effect anything
In the near future its gonna be a 2.8 sled puller

Hey SEAN? Do you need to take the front gear cover off the engine to do this? What about the smarty Sean, I thought that was suppose to add a lot of timing?

Yes, to advance the gear, you have to remove the front cover. Smarty and current timing boxes only change the dynamic curve, they do not change the total static advance. Also, I am not sure if the smarty will over ride the internal timing sensor signal. As of right now, that seems to be the big hold up.
