Injector copper washer thickness?

[skintback]

How much of a benefit would it be to install a thinner injector copper washer to keep the spray pattern more in the piston bowl?

Next would be how thin can you go and where? The stock washer is around .078 i think
and a lbz tip is out about .135 along with the glow plug is out about .200 this is measuring from what it sticks out of a stock head.

Top secret i guess :secret:

I'm going to guess that the wacher is that thick so it has the shrangth to retain cylinder psi and still hold a seal under heat .

Sonny, I just think its something nobody's ever considered, or even thought about. Only people I can think of who may have looked into it would be Brayden or Guy.

If you did that wouldn't you need a different hold down to make up the difference ?

What type of motor are we talking about? How deep do you want to go with the injector Im thinking a combo of cutting the wash and the seat that the washer sits in.

Well this is what i have found a washer out of a 06 CR cummins is .065 and a stock washer out of a LBZ is .080 these are used ones and my gauge is old but gives you a idea of what i got. With the CR washer in the head the injector tip sticks out .150 and the stock lbz one sticks out .130 this is with the hold down tight just like it sits in a running motor.

not sure if this is a waste of time or could it help keep the fuel from spraying the piston lip as bad and keep it more in the blow

I'm going to try it on mine when i get my sticks done up

Just thinking out loud after a few drinks

I think Johnboy put a thinner washer under his injectors to put the tip a little further down in the bowl. The only thing I would be worried about would be the clearance between the piston and the injector.

You would have to go past .200 that is what the glow plug tip sits down and without a washer the tip of injector only sticks out to i believe .175-.180

Ive done this too to try to keep thinks in line with beaucoup timing. They do this with 12V cummins all the time.
