At idle it sure was.

I'm sure it is, common rails tend to be. Plus pilot injection ( if tuned in to it ) makes these run a lot quieter.

I thought it was. It even sounded better. More even and smooth.

These setups from Swamps do not use a pilot injection. They are using the factory 7.3 computer and programming to control a special built Swamp's IDM box to fire the common rail injectors. So there is only single shot capability with these units (unless there is some pilot event logic built into the special IDM box that they designed and built - but I highly doubt it and I really wouldn't think anyone would want that level of complexity in tuning around that without having the ability to control it).

Yeah I wasn't sure that why I stated "if tuned into it", I kinda figured if its a dedicated pulling truck whats the point but you never know I guess.

681 at 2800 is what Ryan said. Graph was strait up

Sounds like a good start. I read something about them splitting fuel rails.

I heard that to. Just do not see how that can happen without very HIGH rail pressure. I heard it happens even at low rail pressure?????

Dzchey21 · Dec 9, 2013

could be ported too big, or maybe trying to run 35k rail pressure, who knows. But i dont think i have every heard of a 6.4 splitting a rail.

Powerstroke Cowboy · Dec 9, 2013

I never heard of a 6.4 doing it. That is why I cant figure out why it is said to one of the problems with the CR 7.3..

97stoker350 · Dec 9, 2013

they had a cutaway of the 6.4 at the dyno day. the rail is about a .25" to .5" thick wall thats alot of pressure to be splitting them. unless like they said they are ported way to much

TERRCO · Dec 9, 2013

So let me get this right, JJ was trashing this guy for JJ ing his engine

Meniacal_Mark · Dec 9, 2013

I would guess they're running high rail pressure on ported rails.

Video of the said dyno run

5:22 is where The CR 7.3 runs

Edit: just realized someone already posted the video

I never said that pilot injection isn't a good thing - there are most certainly good reasons for running pilot injection, even on dedicated competition engines such as a pulling engine. I just said that I am pretty sure the Swamps setup is not capable of doing a pilot injection with its computer (factory 7.3 computer).

if this one is done, why does scotty not have a truck ? remminds me of .. me !

smokinstroker92 · Dec 9, 2013

I believe they are using his engine to do more testing and r&d to perfect the setup and maximize the potential. It has been "running" for well over a year now i believe. But dont quote me on all of that

well i know all that ... but, scotty wants his truck i'm pretty sure.
