4500 RPM from HPCR?

[Diesel Nut]

And the claims that PPE have, 300 more HP with the uploader/downloader? stock parts? How is this possible, I know with the normal Juice+attitude at WOT at 2500+ RPM my smoke screen is a brown haze at 35psi. What do they do dump enough fuel to create a black cloud at 35psi to create that much power?



They are rated at Hp increases at the crank shaft, where most manufacturers rate at the tires. Scrub about 15-20% for rear wheel hp. I would be all in on a DL that would just do the rmp increase and full fueling without the unadjustable hp increase. I think that would be a hot little item to have.

That is kind of what I meant. You know I did not watch rpms on any of the 10 or so runs Sunday. I was watching everything else. The Attitude records shows 3255 max rpms for all of the WOT 1/4 mile runs. So will the Bully Dog Triple Dog "Crazy Larry" program raise that limit by itself???

 

[Digger]

EDIT- BTW this is not the only company I have talked to about this, The other one is working on a program for 4500 RPM for sledpulling, So this is looking like very positive

What company would that be??

 

[TSterner]

i am a retailer for ppe and many other products. i haven't had any luck getting most of them to look at this very hard. hopefully you as a customer instead of me as a vendor will have better luck. thats why i came up with my own mods to achieve over 5000 rpm.

With a lead in like that, I gotta ask... So, whacha got for us?

 

[Tomeygun]

Until I talk to him, I'd rather not say... Not even in beta yet



But this Guy is 3rd gen sledpuller, So he needs this mod bad!

 

[Diesel Nut]

My god thats on hell of a worm!!! Where's the hook???? :-laf

 

[JVolpe]

Does anybody know what sensor(s) are used by the ECM to measure rpms??

 

[TSterner]

the cam sensor is the main engine speed sensor but the ecm uses both the command crank to balance. the tach works with the crank unplugged but not the cam. you cant play with the cam sensor much for a few reasons 1)it will fuel very poorly at some rpms but good at others 2) the oil pressure gauge and alt are data controlled from the ecm if the ecm doesn't see what it likes your oil gauge will scare the sh** out of you and leave your batteries dead. i am working on a cam gear that will let the ecm stay happy and your batteries charged. thats all i want to say for now. i think that electronics will get you pretty far but there are some hardware changes that will make it better. mods to the current system or a dif. inj. pump altogether. .

People using the term "pet peeve" is one of my "pet peeves". Who the heck coined that stupid sadomasochistic phrase.



pet: expressing fondness or endearment, as in "pet name"

peeve: a particular grievance or source of aggravation



Who, except a sadomasochist, would express fondness for a source of aggravation?

 

[JVolpe]

And that answered the rpm question!

 

[Floor It]

The PPE will not fuel fully to 3700 rpm, it has the programing in it but the Cummins ECM does not reconize it. We are working on the ECM part of it, tricking the ECM can be done "sorta" but will be better accomplished by reprograming the ECM part. I have valvesprings,retainers and keepers ready to go right now and camshafts to test for when we get the rpm increase. Like Tomygun said we need rpm bad to keep up with the hard charging duramaxes. 3800 rpm has been reached but we want MORE! We are now waiting for are dyno for further testing.



P. S. We have are own CP3 mod that will also let us make HP at that rpm too.

I was under the impression it worked. Well, bummer. So, whats your mod? You can't throw that out and not have any more info! Give us something, anything!

 

[Floor It]

The PPE doesent work but ours does, I cant just tell you what were doing to the CP3 but it will flow WAY more fuel for the upper rpm's. Right now it flows too much fuel on the bottom end so thats why we need the dyno to tune everything in.

MMMM... . I smell some big HP mods coming for 3rd gens. With a modded CP3, and a 4500 rpm redline, Maybe the mighty 12v will take a back seat? What next 750hp? 800? 850?!?!



(Well I'll take back that 12v comment, But at least the aftermarket companies are welling pumping out good stuff for 3rd gens now!)

 

[Diesel Nut]

Please keep us up on these new pumps. I know I'm not the only one interested. Might have a nice little chunk of the high hp market right there. This really has been a great thread.

 

[TSterner]

one other great point of these new engines is the pistons. they are a good hp design and alow for a lot of lit in a cam. the cam im running is pretty extreme but is working well there maybe a few issues with some of the changes to the head at high rpm. my luck being what it is ill find out the hard way. im going to get stoned for saying this but those d maxs are going to be hard to catch.

Yep, shorter stroke, more valve area per cubic inch of displacement, and 2 more pistons allows the dmax to make more horsepower at a higher rpm than the cummins. The cummins may be a low rpm torque monster, but the dmaxes are really superior in the higher rpm range of operation, which isn't always a bad thing if geared properly.



I am very happy with my dmax, it pulls hard, smooth and so far very dependable.

What does smoking some weed have to do with a duramax





sorry, couldn't help myself



PS - Looking forward to Floor-it's cam in my truck!

 

[TSterner]

there are a few other places to look for a cam. i have a few available for different degreesof perf. the valve hardware i have is very good as well and has proven its self to well above 5000. sounds like floor it is working on some good stuff too.
