WTH? oops, only 5 of those injectors were working 100%. The #4 was injecting about 20% of what it should have.

We found water damage inside that thing Man! You know Im a fan of water injection and all, but not through the injectors. :hehe:

Did you get the boxes I sent you?

How about that number 3 injector? In the videos that engine sure didnt sound like one cylinder was at 20%. Well at least untill the last video that is.

Is this a picture of the new drop in billets?

Don't know if I would call this particular one a "drop in". ;)

It required the cam bore in the block to be line bored with bushings installed all the way through, polished and hardened tappets, and a special thrust/hold down.
 
Don, we have seen a bunch of water damaged injectors lately. Fuel additive should be used that has rust inhibitors/antioxidant additives. Being that we have seen multiple watered sets of C/R injectors comming out of the Texas area, I wonder if the hurricane has contaminated the fuel supplies there? I am not trying to cause any panic. I do think a fuel additive like a Stanadyne would be added insurance. Changing fuel filters more frequently would also help. I know this is your thread but I am just concerned and am trying to help.

What kind of nozzles did you use greg? I have mine simular but comin in from the side instead of the bottom and using NX nozzles and jets. Have not got it completly tuned in yet but it does flow about 1.5 gallons in 30seconds at 450psi. :)
 
Ryan,

They are similar to nitrous nozzles, only much larger and brass. They were made by Staab Machine. I have about 30 different jet sizes that screw into the nozzles. The pump is driven by a starter motor and is capable of 400 psi. The system will be controlled by my PCS.

Will it do 400psi with the 4 nozzles in place or is it 400psi dead head? I hooked my system up to a nitrous gauge so I can watch pressure when its activated in the cab.

Dock-

you going to use nitrous for dyno's and water for the drag strip?

I always planned to run water. I had it mounted before with the nozzles in the intake intercooler pipe but never finished wiring up the controls. I just moved the nozzles directly in the intake plenum this time.

The nitrous is still on the truck, but I have yet to use it with the Cummins in it. The plan is to get it dialed in on the track on fuel w/ water first then we will see about the nitrous.

I'm not going to chase a dyno number as much as get it track ready. The plan is to do ALOT of racing this coming year! :D

Ryan, Yes 400 psi with the nozzles in place ;)
 
Nice, have you check your flow rate yet to see how much its puttin out of those nozzles?
