CTD & PSD Crank 2 Crank What would happen ??

[DieselMinded]

Stupid question but I was board and thinkin'



If you was to take a stock CTD and a stock PSD and sucure them and weld the cranks together and fired them up at WOT at the same time WHAT WOULD HAPPEN .



Would the one with the most HP/TORQUE WIN ??????



Ill Put My Money on the cummins I think when it makes that first stroke it would break the PSD in Half ... .

ROFLMAO!



You have waaaaaaaayyyyyyyy too much time on your hands!! :-laf

 

[PAddington]

I would never even think of doing something like that. :-laf

 

[mjoppie]

need to get you grain farmers back in the field, to much in between time or sompthing :-laf that is a intresting question, odd, but intresting. probably be kinda hard to get them to fire at the same time. would need some good floor mounts, hate to be near it.

MAybe a possible clutch in the center and once they both reach about 3000 RPM THe Cluch would be engauged (at a safe distance)



IT would have to come down to workmanship

Back from the field

Back from the field

As long as the clutch is a SB Iron Giant!

 

[DieselMinded]

There are plunty of clutches that will do it ... not automoble but there out there On my machine at work (exturder) Its engauges with Air pressure and held together if it slips any at all it will disengauge All you have to do is crank up the air a bit maybe have a CTD run a big aircompresser



My clutch holds at 104% touque 1064 RPM pushing polymer @ 8300#/hr through a DIE with 1/8 inch holes also add in 30% fiberglass Stands



Now thats some Butt



Its all 3 phase so Im not sure how to convert the HP/Torque to a mechanical state



I will find out One of our engineers is a good pal

[DieselMinded]

Could it be possible that the CTD would make the PSD run backwards ???????



DM

 

[mjoppie]

dont know if the psd would run but it would probably go backwards :-laf depends where you hit it in the rpm band cummins tq is around 1600, psd is up higher. man talk about a off the wall subject. to much coffee, not enough sleep or maybe the other way around!

 

[Cummins Thunder]

If the ol Cummins shuts er down and the clutch don't slip, then I don't see why not... .

 

[ndurbin]

The Cummins would probably fire first and stop the PSD from firing since the PSD has the heui system and takes longer the crank if you did it from a start.

[tractorface]

They would both break :{

 

[DieselMinded]

Nathan,



We got Away from the dead start theory and changed to 3000 PRM and Drop the clutch.



A bit more interesting





LOL



DM

 

[DieselMinded]

Just Imagine the sound when the clutch engauges ... ... ... ... ... ... ... ... ... ... . I Want to be there



We need TDR to Sponser this

[IC Smoke]

I say get the PSD D-max and Cummins together, put a equal load on them, start em and let em run till there is one last one standing!



that will put a end to all the BS!!





How about we just hook a dodge to a ford instead of just the motors :-laf

he11 I dont care lets just hook up the motors and break some *****! (psd)

Stupid question but I was board and thinkin' DM

Funny this first sentence :-laf I don't think you could secure that PSD in anyway possible, it would be floppin around like a seal on the beach!

 

[DieselMinded]

If you layed the CTD on the ground and suspened the PSD in the air it would make a nice celing fan

 

[DieselMinded]

figgering the CTD torque curve is around LOW RPM's and the PSD much Higher I think the CTD would take the PSD out before it even reached its potential



DM



BTW my motor at work thats being engauged and disengaued is 1500 Horse ! What A clutch !!!

 

[JUeckert]

depends on the application,if it were a t444e ,it makes similar torque as the cummins and at a similar lower rpm range. also bear in mind that the crankshaft on the p stroke is shorter and has less torsinal stress than the inline 6, hence the need for the xtra main bearing on the 6 cyl. also keep in mind, the crank on the p stroke is similar in size[dia] to the cummins. i would think it would come down to the quality difference in metals[if any]. been my experiance with the powerstrokes ,that due to its fuel system,resulting in its slow throttle response at lower rpms,hooked crank to crank,the cummins would likely gain rpms,and the p stroke stall.

 

[EMD Diesel Power]

Get one that runs clockwise, and another that runs counterclockwise and forget about breaking anything..... you'd have the power of both engines. lol



As for the normal results..... you would probably blow both cranks on both engines..... Assuming the clutch held..... If the clutch fails... both engines survive.





Everything in this kind of war will come down to crankshaft torsional strength and the ability to hold the torque (not necessarily its own--- but also the opposing torque of the opposite engine.



I vote for the Cummins on this..... bigger, stouter and heavier crank. Also the inline design will benefit as well... . will hold torque better at engagement. V-styles dont hold torque til the revs are up.



And if you want to see a big crank... . look at a locomotive or a ship one.



On EMD locomotives... . the crank will keep turning for about 15 seconds after shutdown. ---- kinda cool to listen to it spin after the fuel has been cutoff. Crank is around 5 tons if Im not mistaken. I believe GEs do the same thing. Nick can chime on on those. :-laf
