Cubic Inch

I'm talking poorly tuned, black smoke-belching sledpulling terms... :hehe: :hehe: What's your version of cc's needed for 500hp on an anemic 12v?
 
Allrighty, I really like this thread.

First, I've been told that when people say "cc" for a P-pump, they mean cubic mm, right?

Second, I've heard of some wicked P-pumps that'll do 750 "cc" on all-out smoke belching you know what pullers. Is this about as high as it goes? Are there any much bigger? What do the Sigmas do.

I guess what I'm getting down to is, will it take 3 or 4 CP3s to keep up with the meanest P-pumps out there?
 
Just for reference a Sigma to my knowledge can be had with 19mm plungers. I would say capable of the 1500cc+++ range easy.

500hp on an anemic street truck or pansy drag truck would only need about 375cc of fuel.:)

You're right. I have no idea what I'm talking about? I got it stuck in my head that mm3 == cc. What I was trying to demonstrate was the amount of fuel required for a CR @ 500HP is much, much less than a PPump and my math got cornfused. 120 mm3 = 12 cm3? so a 12 cm3 CP3 pump is putting out the same RWHP as that of a 375cc ppump?

I have something completely screwed up and I'm not sure what.

I would say the big Sigma's are putting out more than that...close to 2000 or even more! When I had my P-Pump built last year and with all the internal mods that I had done to it (13mm p&b's and a few other goodies) on a 25HP stand it was pushing 1000cc's at 5500rpm/1000 per minute or something like that. I had it turned down to 700cc's at 4500rpm but have since bumped the rpm up to 5000rpm.

In the end though just like this cubic inch thing...it comes down to money. I spent more on my pump than most do on there engines!

Building it from that, no. Hijacking a fedex trucks engine just after wrecking into it....... SlightlyLOL

CDS P-pump 13mm is listed upto 1300cc. http://www.columbusdieselsupply.com/tp3c.php

CDS Simga 16mm ????
If the travel was the same as a P-pump. It could move 1930cc by my math.

CP3 is good for what 400cc?
 
Just for reference. 3785cc in a gallon.


Wonder how many HP pump stand one would need to test a 2000cc Sigma?:st:

well, if a 25hp stand will top out at being able to push 500 at rpms, you would need a 100hp motor to spin a sigma at 2000cc. And a 3 phase power line, and some $$$$$$$ to buy the test stand.

3 phase.... Guess that means I will never build it then. I have bad enough luck with 2 phase at the box.....

Been awhile since I have heard it called 2 phase. Only in Missouri I guess.
 
Does PSI have anything to do with how many CC the pump can deliver?
 
Higher PSI would speed the delivery rate and also could help with atomization of the fuel.

So pressure has nothing to do with the volume that's delivered?
 
Columbus uses a 100HP stand I believe to test the sigma. At least they told me it takes 100 hp to run on my truck.

I like how the cubic inch thread turned to a pump thread :kick: oh well, at least the sigma is being mentioned.....and as for cubes, I have heard of a 5.9 getting 396 with a stroker crank. Not sure whether it was offset or custom or what...that's 6.4L or so by my math.....

It would increase that also. The key is to the higher pressure is your able to get the fuel in faster!
 
Well, when we say "1000 cc" it must mean *per minute* (or some other time interval) of the entire summed output of the pump.

Maybe I'll call CDS. I need to get the math straight.
