It works but you must not over do it. I used an rv water pump with a pressure regulator on it - sort of followed F350Camper's lead, but I increased the pressure which in turn increased the flow - which lead to way to much injected which caused me to crack the pistons.
It does not lower the EGT's it just stops them from climbing (that's what I seen), you can feel extra power when the system kicks on for pulling a hill or just blasting down the road.
How I did mine was I wired up an oil pressure switch to the intake (to read pressure off the manifold) then had it apply power to a lock off solenoid, then once I flipped the switch the lock off solenoid would open but the boost pressure would control when it came on and off after that. I did it this way so the pump would supply pressure up to under the hood then all I had to wait on was for the fluid to go from the drivers side fender to the intake hat, not all the way from the bed mounted pump. I can't remember what size nozzles I used but I got them from Rob (F350camper) and I got the lock off solenoid from McMaster Carr and all the fittings from the local hardware store - I used braided line from the hardware store as well.
Again what how much fluid you are injecting because too much and she runs great for a little while but it comes at a high price. If you were to use a lessor amount of flow than I did you might get better results (longevity) but I can't say for sure because I only did one system. I think there is an article on here about the Slash system that Rob put together or at least there used to be (article section).
