has anyone ever hit 4000 rpms in our trucks??

Yeah, it was definitely a marine engine.
Anyways, not to hijack the thread.. but I'd love to hear an old stroker that wound up. I'll take our 78' Kenworth up to about 2600 sometimes and it sounds wonderful. Especially with the two jakes when she winds back down during the shift.
Is there any real benefit to running these high rpms?

I can hit 3700 RPM pretty easy and I believe 3900 is the max though. I definately loose boost etc immediately when I hit that. I spun mine up pretty hard one time and saw it jump above 4000 for a split second between shifts. I believe our PCM shuts it down around 3700-3900.
If it shuts it down at 3400 like Tim said I must have programming that lets mine go further because I can easily go above 3400. My power really starts kicking in at 2500 and increases drastically up to around 3600. I believe if I put a map regulator on there I could go further. Mine is just a daily driver but a fast one. I don't run her up that much very often though.
I kind of wish I could go above 4000 at times because it has so much acceleration above 3000 RPM it feels like it is just getting started, then when I hit the top end of 3000's it just shuts down.

there's been lots of talk about different types of setups for our 7.3s... stealth oil systems is making a new oil system to allow our 7.3s to finally have the oil capacity with the HEUI system to use injectors that can theoretically make over 1000hp.... also there is a commonrail 7.3 system in the works for 2-3 years now.... mechanical 7.3s.... lots of stuff haha
Mechanical 7.3s ... P-pump your Powerstroke

Nobody is making the common rail setup. They are being fabbed up by people.
As far as cost.. I'd look around 15,000-20,000 by the time it's said and done. Not to mention the hours upon hours to get the timing down.
It's been discussed before about getting a pump from a v8 MACK and fabbing up a system.

the common rail system, i hear the programming alone is about 3k, the system itself... well over 10k... claimed over 1000hp easily with the setup, and availability is limited, but if you got the money you will be able to get it.... and as to WHO, i've never been told a name, but heard from a reliable source that it's a big name in the powerstroke world

yeah but it sure would be cool to just have that option haha even if i'll know never be able to afford it
#41
I cant remember when it starts dropping pw at, maybe 3200 3300 rpms. A chip will not help that, it is a hardware problem.
