ok now that we have stirred up many ideas on plate grinding. i think you should know how to do it.
the factory plate is very hard, i mean it is close to file hard. i have not rockwell tested them, but take my word they are hard. i grind them to the profile i want with a bench grinder and a coarse rock. it will need to be cooled a few times in the process. then to the fine side to remove any grinding marks. then on to the deburr wheel to polish it up nice and smooth. if you don't have access to a deburr wheel a dremel tool with a rubber type abrasive will polish it up, just takes more time.
just don't get in a big hurry, take your time and have fun. mike

 

Thanks for the info.

 

Thanks, was wonder how yall were grindin them. Someone could get real creative and draw up a profile on CAD and machine it with a CNC mill? That would be interesting.

 

I have had good luck with a die grinder.

It does take a while though.

 

Stock plates are case hardened, I Rockwell mine after the fact to find out. Really don't know if the governer arm is making strong enough contact to flake or chip the plate away, even soft.

 

Does anyone have any pics of where your grinding and how much?

 

I can't imagine how long it'd take grinding something hard with a grinding stone, I use a double cut rounded end carbide burr in the die grinder for stuff I want to go through quick. I bought it for porting my Talon's cast manifold. It still takes a little while still but it does chew away quite fast, no comparison to a grinding stone (but always finish with that or sandpaper).

As for pictures....

From Forrest's gallery, but it is GunRacer's #100 plate.

Would you happen to have the profile for that gunracer? I only have 70mb of CTD pictures and such saved on my hard drive, I need more.

 

it takes less than 5 minutes on a good bench grinder. and i grind the #100 just from memory any more.

 

I ground mine to that 100 profile and love it! I get somewhere around 38psi now with the stock injectors and stock turbo. before it wouldn't get over 28.

 

Whereabouts is this #100 profile. I dont have any money to buy a new #10 plate, So I think I am just going to grind my own plate for now. Any info would be helpful, Thanks.

 

I think it is pretty much from the picture posted above.

 

Does anyone knwo if its really true that it is safe to run it without a fuel plate?

 

Took about 20 minutes in front of a generic bench grinder with a pretty coarse grit wheel to make this out of a stock plate. Then another 20 minutes with some fine sand paper to smooth it out. Works decent.

 

it took me about 5min to grind mine to zero talk about some precision grinding when i use to work at my last job i was going to use our edm and burn some plates but never got around to it

 

u guys ever think about getting a stock plate or two from ur local cummins supplier? would they have em?? ..im sure they'd cost u about 20$ as opposed to a 200$ plate from all the companies that are making them right now...i was thinking of going to a big truck wreckers and checking out their 8.3 cummins and 5.9's if they have any cause they have the same pump hence the same plate

if u had 2 or 3 plates u can grind them to whatever and try em all out
