Torque.....

[jollygreen6x6]

Hello. I have heard all over the place that the infamous R6602 gasser is a real torque monster. I have one of these in my truck, so I just happen to know this .I also know the horsepower on one of these puppies is supposedly around 192. What I would like to know, however, is the torque rating this beast has. I really just want to know how much @$$ this thing can haul... :devil: :devil: :devil:

I have the mechanical manual for the R6602 on CD. I don't think it lists torque, but I will check.

Well ??? I wanna know too, I looked around on the net for a little while and couldn't find anything ! So who has the specs , curious continental owners like us want to know. P.S. I need a copy of that CD as well !

 

[rdixiemiller]

Send me your address and I will get a CD out to you. I have the parts book on the 6602 on the CD, but I have not found any other manuals yet.

I PM'd you on the 20th , so I PM'd you again in case that one didn't go through. Both have my address, I want the 2.5 and the 5 ton for 7$ and the 602 CD. PM me where to send the $ to. Thanks Mark

HI THE FORMULA FOR HORSEPOWER IS;

TORQUE*RPM

hp= --------------

5250

sorry about the double spacing...plug in the numbers you have and you should be able to solve for the torque rating.

if this is unclear you can go here http://vettenet.org/torquehp.html for a broader explanation.

hope this helps.

If you back peddle from that formula you get about 360 for torque...and that ain't right. That calculation doesn't take into consideration displacement. I can't find any torque numbers on my 1160/3208 CAT V8 either. I know it's 636 cubes, 225hp, 5" stroke, so I figure I ought to be in the mid to high 400's or more on the torque side...oh, plus I got a big air filter and very free flowing exhaust.

here's another site that lists the specs for the gas 5ton continental engine as 224 hp@ 2800rpm.

according to the formula





horsepower*5252

torque= ------------------

rpm





the r6602 would make 420.16lb/ft of torque at rated speed.finding the peak torque is a job for a dyno i think.you might be able to guesstimate the torque curve with a program like desktop dyno.lots of fun inputing the build data though.

cheers

oh and these guys have an engine service manual for you,might have some info there...

i gotta stop feeding my emoticons chili

Well, I have heard several stories about how the R6602 seems most powerful between 1300-1400 RPM. So, lets assume peak torque is at 1350 RPM. If we use that for RPM in the equation:

224 horsepower times 5250 equals 1176000.

1176000 divided by 1350 RPM equals....

871.1 ft.lbs. of torque.....

Yeah, I'll go with that.

 

[DUUANE]

close but not quite...224 represents the peak horsepower.actual hp at peak torque would be considerably less.if i had to guess i'd say 120-150hp@1350rpm ,and that might be optomistic depending on the volumetric efficiency.in my opinion there isnt much that'll out torque a properly prepared cummins 855.
it's comparing apples and oranges though. :skull: forced induction :skull:

makes wonderful things possible.i've heard tales of 1200hp at the wheels @1950rpm in a hi-way tandem tractor.i'll try to find the link and post it.cool stuff.

cheers

Duuane's formula puts my CAT just under 425tq. Hey, I'll take that. It yanks that truck around!

 

[jollygreen6x6]

Looky that...I FOUNDED IT!!!!! []

http://www.mil-veh.org/archives/02-10/0677.html

Actual torque rating of R6602: 504 lb.ft. at 1500 rpm.

A far cry from 871,

but still......

 

[DUUANE]

YEP 144 HP@ 1500 RPM. NOT BAD FOR A STAB IN THE DARK....

GLAD YOU'VE GOT THE FACTS

REGARDS

 

[spicergear]

Hey Chaz...now find my two and a quarter horse 1160 CAT! []

 

[jollygreen6x6]

Hey Spicergear...NO.

 

[Westech]

lol he told you

 

[spicergear]

LOL! Sure did!
