I kinda figured that something took the load off to have it spin that high.

 

HOLY CHEESEBALLS that is a lot of RPM's!! Thing sounds crazy though, never heard one wrap that high before.

THAT's what it was...I don't know why I thought ring and pinion!

Man, anybody know how to save a copy of that video?

I really want to take it to a buddy of mine......he will freak out!

 

Id like to see a picture of the hole in the block.

 

IIRC

i am more than certain anything over 4100 rpms you are playing with fire with the stock bottom end of the engine. I myself see no sence in actually going over 4000 rpms with what im gonna do with my truck, tow and have a little more power than what i currently do. If you wanna play and sledpull then sure 5K will work for ya, but for many other things, i see no need for more than 4000 rpms, even at 3500 i sorta draw the line....

As chris (signature600) has stated before U cannot have a tow monster and track monster at the same time, its one or the other, or a balance of both.. hence my goal...

I don't see why you wanna go over 4k anyways. Unless you've got the head ported and a new cam in there to help move the air and let the engine breathe your not really gonna be making any more power. No sense in stressing things for being able to say that you can rev that high.

 

Brandon posted this vid it it sounds wicked bad. Dunno how many rpms is was but it sounds like a lot

Yep...when I push RPM up over 3500 all I get is more heat! EGT's stay under 1300 until I go above that

After hearing mine at 5500RPM, that's higher than 5500 IMHO!

I HAVE a PDR cam sitting in the garage that is made to make power UP TO 5000RPM's, I don't necassarily want to go that high but 4200-4500RPM's might help me break 600+rwhp on a LARGE single I would think...? My truck is a daily driver/play truck, I hardly ever use it to haul and when I do it is light stuff. The next thing I purchase (indicated by my sig) will be a complete new head from Pure Diesel Power that will be ported, polished, HD valve spring'd, and larger valves plus O-ringing. Should I just install a 4gsk and "possibly" send my pump off to have the governor assembly lightened? I am even tossing around the idea of when doing the head ripping the pistons, rods and MAYBE crank out to get them balanced... but I don't necassarily know how much that will cost... Any ideas? I might be going back to my old job cutting hay but using this truck would only last as long as it would take to find a '94-'95 Single cab 4x4 5sp dually to buy and use.

 

With 4k or 5k springs, the trucks run so much different because there's FULL fuel from 1700-4000 (or 5k). The stock trucks rev to ~3300, but start pulling fuel at 2700.

BTW, the pump shop said 4k springs will only run 5200 with the 4k kit set like mine (6 clicks).

You know, I got to thinking ( dangerous I know )
If you watch that video, there was a fair amount of time, relatively speaking between the tranny failure and the ventilation of the block.

If one were to put a NO Solenoid valve in the P-Pump feed, close to the pump and control it via a rev limiter, wouldn't it function as a rev limiter after a fashion? Certainly it would not be a soft touch, but with the volume of fuel these things push at full song, any interruption would prevent it from revving pretty doggone quick.

Perhaps it would ruin your barrels on the P-Pump, that I don't know, but it would probably save the rest of your engine.

 

my truck snapped a connecting rod in #1 so im having the crank and the hole rotating assembly balanced.if its worth the m0oney i might have the crank knife edged.i got connecting rods that are really stout,they are knife edged and some other stuff froma diesel drag friend. but i was told that the cummins engine is really well balanced when they first go in. we will see i also bought arias pistons with fly cuts and a ceramic upper if you need any info on the parts pm me and i will give you some links.

 

In both videos, the driver had no time to react. I wasn't anticipating a broken trans shaft and Straley had no intentions of breaking either. You saw how much time it took in my video to figure out something was wrong and kill the engine? The instant the trans gave, the datalogger showed a gain of 2200 rpm in less than a second. It was still going up when the crank pickup failed.

Chris are u sayin that youre turnin 5500?
