want to advance timing

my 92 needs more power! I've turned up the pump and heard advancing timing will give more. Anyone have a write up on doing it? What are disadvanteages of doing this?

Advancing the timing gives you a lot of power,I went from a 14.49@90mph to a 13.95@96mph with just turning the pump an 1/8"

Ok, so how much do I turn it? I know on inline pumps you can test where your timing is at with a drip tool. From what I remember about the rotary pumps on the old Ford IDIs you had to adjust timing dynamically.

Is this just an estimation of how much to turn the pump (I see 1/8" a lot). Is this usually only done on turned up pumps (I can see obviously why it would be better for trucks with 3200 rpm springs). I will be tuning the 1 ton for big power, but keep the D250 utility body stock unless it gets sold. Would advancing the timing on a stock pump give me any benifits? Thanks guys.

An 1/8" bump will work well on pretty much any truck. You ought to bump the timing on the '89 just to help the fuel economy. On the '93 you will probably wind up jumping the timing gear a tooth once you get some fuel in there.

with the 3200spring, DennyT fuel pin, POD's, Fuel screw set to near run away, HX35 I have the pump pushed all the way to the head and may move the gear and advance it more. I realy like it.

No, it's always a good idea to bump the timing. I just meant that with a lot of fuel you need more timing than is available with the timing gear in the stock position. This is not necessary with stock injectors.

I believe wanna was saying that for MY 93 because I plan on making that my hotrod while I plan on making the 89 just a good MPG work truck. Skipping a tooth on the pump will give an advance (or retard it if done the wrong way) more than you can do just by moving the pump toward the head because the pump is realativly close to the head as it is.

Thanks guys. Looks like an easy proceedure, but I don't have a wrench that will get to that lowest pump mount (the s wrench) where I am now in Charleston, SC. I guess I'll adjust it after Friday/Saturdays drive home to Maine.
