5,000 RPMS on 3rd gen.

[DerekW]

Not using the factory ECM,. Complete stand alone system. Like Ted said, the roller lifters, upgraded push tubes, and better valvetrain have been around for a while. The trick to higher rpm is to put a mechanical pump on it like Ted did or build a stand alone engine management system.

I would perfer stand alone Engine management and I understand the needs of the valve train and bottom end of which I plan to address once I break the barrier of 3700 with a ppe

 

[DerekW]

The technology is out there. You wont "have" to do anything internally. We run mod engines over 6000 rpm on a stock crank and marine rods, which arent supposed to be as strong as the cracked cap rods your engine allready has. I would suggest running heavier rod bolts and main studs for the extra insurance. You will need a cam that is matched to your intended operating range, roller lifters wouldn't hurt, you will need to go through the rest of your valvetrain as well. Other than that, its just a matter of setting up a custom computer to run everything. Its doable, just not cheap.

I would like to see your credantials and like a website If I like what I see. lets get the money rolling and those rpms going.

I could be wrong but this is starting to smell more and more like and advertisement for someone or something. If not then disregard my comments, but if it is then just come right out and say it and stop phishing.



Sorry but there are just too many things that don't add up.



You're right you are on the cutting edge of things. :-laf

This is not an advertisement in anyway at all. This is a personal thing. I have been trying to put it in words here on the keyboard for the last 20 minutes but I just cannot find the right words. My goal is to take the big guy down out the formerly local track to prove myself. he is not part of the bad past. But I have to beat him to prove myself.

I am leaving you in the dark simply because it is a bunch of issues that don't need to be discussed on the internet.

 

[tshort]

How is your buddy runnin a Redline box on a 12v. Or am I just missin something.

I guess I am not sure how much cash you have to put in your rig, but understand you can have $5k tied up in just the transmission, and easily another $10k in the engine, fuel system, air system. Are you building a twin setup? The one area I see an issue is the charger, finding a charger you can light in second gear, and still move enough air for 5,000 rpm. I am sure there are better ways to do things. Which videos have you studied? The commment you made about a pull off and using 1st gear makes zero since still to me, no way there is enough ground speed unless your gonna run on the high side of the transfer case. I am still curious about the hours of math that you have used to figure this out. Just gear ratios, and wheel speed? Or have you calculated HP needed to move 40,000 lb sled 300 ft, that has a non constant friction coefiecent with frictional forces increasing by the square of velocity traveled. If so I want to see that equation and what assumptions were made to develop the answer. You may or may not have novel ideas, that is the idea of this forum to exchange ideas, and learn from others. We aren't asking you to give away the exact details, just answers to some of the questions and people can probably provide you with a little feedback, to further increase your success. May save your pocket book too. You have mentioned driving 500 miles to change to your race setup(VB and what not) What happens when you blow the axles out of the truck? Blow a headgasket? Lose a charger? These are the things that makes me really wander where your going with this.

I would think that this is where something like EFI live (for a cummins that is) would come in handy? Or am i way off base?

Supersonic only had the top truck in the DHRA modified series this year.

No EFI Live is exactly what is needed. Or like Chris said a totally stand alone computer which either hasn't been made yet and/or would be priced so far out on left field that it wouldn't be feasible for a street truck. This guy is phishing. I'd venture to guess he doesn't have anywhere near the number of zero's in his checkbook or knowledge to attempt a one-off stand alone computer system. If he does, good for him. However none of his posts thus far have convinced me anyway.



P. S. I know how to cure cancer, but I don't want to talk about it on the internet!

Sell the Cummins, buy a 6. 0L Powerstroke, put a SCT programmer on it and turn 4700RPM O, and make sure you say your prayers before every pull! That would be cheaper than anything you can do to your current truck! But lets face it, calculating stupid ****, and you come up with stupid ****, sub 6 second pulls down the track, PLEASE! You really have no idea what you are talking about!

 

[csevers]

So far I have enjoyed reading this thread and it looks as if there is much more to come. Just for the hell of it I timed some pull vids of Crowder,Stacey,Watson and they come in between 10-12 seconds from the time the tires flinch to shutdown so if this guy is moving twice as fast with street tires he has his SHEET figured out!!!!

[jwilliams3]

Yeah theres gonna be a sledpulling revolution :-laf :-laf

6 second 300 foot pull with a daily driver that drives to the track then drives home!!

 

[Vaughn MacKenzie]

ive had them in my common rail block for over two seasons. great design. way better than the rollers for the older blocks.



ted

I'll be danged, never knew that before. A CR block would make a great foundation for a performance 12-valve buildup.

Maybe he's using one of these to help with the speed. :-laf



I was wondering if anyone could help me with some math. I'm looking to get 8K rpm out of my '05 CR. The way I figure it if I was doing 70 in 6th and downshift to say 2nd or so I think 8k is feasible. (simple downshifting) I'm not really worried about the valve's since I'm sure the pistons will help close them for me. Is this the best approach or would a healthy shot of ether be the better option. (and with my cash flow I could buy an entire case of ether, oh yea that's how I roll)



P. S. Is there anyone in the Ohio area that would let me borrow their truck for a few minutes.

Hot damn fellas ol' Schwartzy is on to something here! Oo.

 

[zstroken]

Derek, you still haven't answered some of the questions that were asked. While you may have very novel ideas, they also may have already been tried by someone else and they may or may not have had success. This could save you time and money. I have a second gear start video for you. The dieselplace was down. If you want specifics on what happened, ask I can give you the low down.

OK guys, I did not read the entire post, but my 2 cents: I think 5K is very acheiveable. Cummins motors are so burly inside 5K is not going to hurt anything but valve train. You will need a camshaft that produces power in these ranges I sugest the F1 helix 3 ( I daily drive this cam, and it is really mild for street use, but does pull hard up on top!) you will also have to buy f1's springs. I would also go to titanium spring retainers, but I cant think of someone who makes that part for the 24v head? Once this is established, I suggest you start making some calls to people who can do custom programing. You can have them set the limeter in the ecu, and you will need ALOT more timing to make power up top due to the slow burn rate of diesel. That is all I see needing to be done. Whoever told you custom rods and crank is silly. After all 6000RPM pulling trucks have mostly stock rods and cranks (i'm sure there is some crazy custom stuff too) If you get a good camshaft, and adress the valve train, your motor will be a beast on top! I remember the 1st time I watched the needle on my 12v rocket past the 4k mark It was all worth it! Your electronic injection should maintain good drivability!
