Torque Converter/Turbo size

[notlimah]

Gotcha, so you'd just prefer the truck to rev a bit more to get the turbo spooled before putting power to the ground. I'm starting to get this lol

Kind of like launching out of first or second on a manual.

So here's another question, what is considered stock stall speed? I've seen multiple different answers, some say 1600 while others say 2300, is there any really way to tell?

 

Also wouldn't it make sense that if I have say a stall speed 2-300rpm lower then stock and then increase my hp/tq numbers that that number would increase?

Last note, I have had an intermittent lockup hunting problem that I haven't yet found the fix for.  The low stall converter is much less violent than a high stall when it moves in and out of lockup.

 

 

have you started a thread about this? Or when you say intermittent is it based on humidity?

Stock when accelerating i saw 2,100 rpms regardless of how hard i put my foot into the throttle, not sure if this helps.

Yes. Power brake the transmission the point at which the transmission starts pulling on the drivetrain  at it max rpm is the stall point in the basic sense. I'm pretty sure you'll have a tough time doing this. Old school method of checking stall speed.

This is true, but if you exceed the stall speed and lock up the tc you risk destroying the TC, and or snapping shafts, just hope you have a billet input shaft, because when they let loose they usually take out the TC and the transmission pump with it.

I'm not saying mat the throttle to the floor to test it. Like even in my 96 Dodge 1500 it extremely difficult to do being the tires let go before you reach the stall speed. Like the older 727 transmissions you could do this fairly easy back in the day.

I agree.  It will give you an idea, similar to if you floor it off the line.  The RPM at which you really start to feel the push and stop seeing your RPM rapidly change is your stall at that load.  

 

Stall changes with load, engine RPM, and engine/trans differential RPM.

Sorry if I was coming off in a way that said you should feel differently about your experience. Completely understand your point and value your opinion.

 

I was just trying to point out that it seems weird that trans builders and recommending one thing and then guys are running it with sub satisfactory results.

 

Maybe it's just 100% user based opinion and subjectivity regardless of whatever 'the right way' is. Or maybe just an expectation that isn't realistic given the setups? I don't really know as I'm still on a stock trans but in a couple months I'll have a different opinion so I'll chime in with first hand experience then.

 

Again, sorry if I came across like I was trying to tell you your experience should've been any different then it was. 

 

It is hard to convey tone across text. Dynamic argued with me before on how my truck was behaving. Do not take it personally.
