what happens if the govornor arm goes beneath the plate?? like if ya slid a plate too far foreward. What exactly does it do and what happens?

This subject just died at this point. and maybe it was erevelant at this point because it went in to a different dicussion. I also was wondering. Is this what causes turbo lag? the tip of the lever goes under the nose of the plate? and then emerges later when things change, like enough boost, or pedal travel? I noticed that mine has always been a little harder to push down when the engine is off half way down. And some times when the engine is runing. Now this was with a # 5 plate where it has the taper on the nose bottom side. Closer examination shows skid marks on the toe bottom, So If I continue to use it the lever adjustment will have to be done. On The stock plate the lever hits at the bottom edge where it should.

trun your key on so that the engine shut off selenoid is in the on position and open your throttle and see where yor govenor arm hits if it is below the edge then you have to adjust your govenor arm.

The fuel pump won't be able to put the fuel to the injectors. In other words you will castrate the engine (no power).

On what pump? #5 plate does not work in a 160 or 215 pump without highering the gov arm.
the problem is the angle grinded edge (bottom) from the tip down

when the arm rides under the plate, ive noticed: less power then when it hits the plate
one little smoke cloud, and it defuels harder then when it rides along the plate.

That is a great picture!!

I have heard, allthough it may not be true, that you can take a piece of flat iron say 3/8" or 1/2" and make your own fuel plate... Anybody know if thats true?

Yea, you can do that. If you have a stock plate you can make just about any profile you want.

since this is about fuel plate profiles... im trying to grasp what the fuel plate actually does and how it does it. im guessing that there is an arm w/ a tip which acts as a follower. the tip rides the leading edge of the fuel plate and this dictates the total volume of fuel allowed to be delivered to the engine... basically, it determines the fuel curve that a specific engine receives.

am i to assume that the bottom edge of the plate is off-idle or the bottom range of throttle angle/input? when the truck idles, does the follower sit below the bottom edge of the plate? does the follower move up the profile of the plate as RPM's increase or as throttle input is increased?

are the plate profiles dictated by supporting mods and the volumetric efficiency of the engine itself, or does it depend on something else that im unaware of?

im so used to building turbo gas motors and needing different fueling based off turbo efficiency ranges and boost levels.

flubyux2, take a look at THIS ARTICLE. There you can see how the plate sits in the pump and other parts in relation to it.

sweet... at least it puts a face to the name, now i just have to learn more about how this guy works. looking at the last pic reminds me of looking at a cartoony mouse trap set up, waiting for something to trigger all the action... but its hard for me to envision how the components interact during different engine operating parameters.

thanks
