This is a great video. Years ago I had a Rover 800 2.0 litre with ZF HP14 4-speed automatic gearbox. They were sold as Sterling in the US and I expect they had the 2.7 litre Honda engine over there. As I was having the engine and gearbox rebuilt I took the opportunity to have a custom-made torque converter. I told the torque converter company that I wanted the lowest stall speed possible. They said they could do it, but it wouldn't work as the engine would stall as soon as it was put in gear. I went away to think about it, and the maths involved, and I concluded that they were wrong, so I asked them to go ahead and build it that way. They supplied it to the mechanic who was putting the gearbox back together, and after having supplied it, someone higher up in the company rang him up and said, "We're sure it isn't going to work, so if you return it now before it's fitted, we'll put it back to normal at no extra cost". Clearly, the discussion about it had filtered up and someone more senior had eventually taken a look at the spec after it had already been despatched. I went away and thought about it again and simulated it in my head, and I concluded that I was simply going outside their normal envelope of experience, and that they were extrapolating linearly outside of their experience instead of in proportion to the cube root, which is indicated by the maths. Plus, I'd reached the point where I had to know if I was right or not. So I told the mechanic to go ahead and fit it. I've got to say that it was almost perfectly how I expected it to be, in that there was a bit of an extra 'kerthunk' when it went into Drive, and the engine vibrated a little more on tickover when stationary, as the torque converter was pulling harder at tickover, but it didn't even come close to stalling the engine. Driving through traffic was lovely, because a lot of the time I only needed to take my foot off the brake to keep up with slow traffic as it would creep at a much higher speed than normal. To make decent progress I only had to breathe on the accelerator and the first to second gear change was extra silky because then engine was revving so slowly when it happened. Commuting right across London at the time I managed to average 35mpg over a tankful, which is pretty good considering that it was a 2-litre, long and relatively heavy car, driving through one of the heaviest traffic areas of the UK for most of my journey each day. But I was especially delighted that my experiment had worked, and the experienced, qualified professionals were wrong. The downside is that at the traffic lights Grand Prix it was definitely slower, because the torque converter was holding the engine speed down to a lower speed all the way through each gear, but if you use a car for normal commuter driving and not racing, then a lower-stall-speed torque converter is much nicer to drive with.

Let me simplify this for everyone....the front spinny thing uses fluid to make the back spinny thing go around and around. The engine speed required for the front spinny thing to spin the back spinny thing when you mash the accelerator thingy as fast as you can is called the stall speed. I don't know why they call it stall speed because it doesn't stall when its spinning.

I read a number of explanations over the years from 1979 to maybe 2005 and none of them mentioned the one-way clutch. But it never made sense the way the stator was said to divert the fluid and add to the torque unless there was also something to stop it from spinning backward. Finally, in 2005, I just added "one-way clutch" to a Google search on the subject and found a more complete explanation than I'd ever seen before. I guess I could have just asked a transmission shop, but the few I'd had reason to visit seemed too busy for educational questions.

Thank you for making these videos. Curious about stall speed application. I’m guessing a high rpm hydraulic hookup would be used for drag racing where ya only care about 4-8k rpm. A slow hydraulic hookup, say 800 rpm for a Diesel tractor. Am I in the ballpark?
@HughesPerformance
@HughesPerformance 5 жыл бұрын
Thanks for your support and for commenting! We really appreciate it!! You're definitely thinking along the right lines. The vast majority of torque converters that we build for dedicated drag racing applications will typically provide a flash RPM of anywhere from 4,500 RPM to as much as 7,000 RPM and beyond, depending on the application. We tailor the necessary stall speed characteristics and converter coupling point to each specific application when it comes to our custom converter builds. Modified street-driven diesel applications will typically utilize a torque converter that only provides around 1,000 - 1,500 RPM of flash stall speed. Due to the torque output of diesel engines and the relatively low RPM ceiling, diesel applications typically need a very low coupling point in the converter. Hope this helps!!

Up to the end of the 1967 model year, GM made "switch pitch" torque converters, which increased the stall speed if the accelerator was depressed most of the way. It seemed like the best of both worlds, but I've heard it could be a reliability trouble spot. Do any aftermarket builders make switch-pitch converters today?

The BTR LS3 Stage 2 camshaft really works better with a higher stall torque converter. It's a great cam, but it's barely tolerable with a stock torque converter. I recommend our part number 65-25L. This is our Street Master 6L80 model that will typically provide stall speed in the range of 2,400 - 2,600 RPM with a combo like yours, will provide more favorable idling characteristics in gear, and still maintain fantastic drivability.

Thank you for this great explanation. I was wondering why does the slip ratio reduce as RPM increases, I.e.: if you have a flash stall of say 3,000 rpm then you have close to a 3,000 rpm difference in input shaft to output shaft speed, but once the engine reaches say 6,000 rpm the output shaft would be much closer to the input shaft speed. Thank you for explaining that centrifugal force enables the fluid to transfer more energy.

I really appreciate the vid..My knowledge of "High stall" is to get the engine in the sweet spot when you stab it as well as be able to idle with a large cam(low manifold vac) but the actual size of the converter is much smaller as the stall speed increases (Factory V8 converter over 3500 rated converter)....I'd like to know is that a smaller oil volume thing...

@HughesPerformance 5 жыл бұрын
Great question!! Thanks for commenting here. Oil volume inside a torque converter does indeed play a significant role in the stall speed characteristics and coupling efficiency of a torque converter. As torque converter diameter decreases, oil volume obviously decreases as well. As oil volume decreases, there is less fluid available to offer resistance against the impeller as the engine is running as well as less leverage being generated from the impeller to the turbine due to the smaller, shorter impeller vanes. Consequently, as more engine torque is applied to the impeller, a corresponding rise in stall speed occurs. Additionally, most smaller diameter torque converter cores typically come from OEM applications that feature small engine displacement with relatively low torque output. As a result, the impeller designs commonly used with many smaller diameter torque converter cores feature more neutral or even negative impeller vane angles. As the impeller vane angle becomes more neutral or negative, stall speed increases due to the higher RPM required to create efficient fluid acceleration between the impeller and turbine.

In my Dodge truck, I could foot-brake stall and get the same as static stall. I pressed foot down hard on the brakes, and also pulled the E-brake, and that was enough to keep the tires from spinning under a WOT punch. Got ~2200rpm

Some vehicles do have enough brake system holding power to achieve maximum converter stall speed. As engine torque output increases with modifications, that becomes much more difficult to achieve.

So my truck makes 265 full at 2000 rpm. (Ford 300) if I foot brake it it does about 1500 rpm. Is there anyway to determine how to determine my stall speed based on that?. Its totally stock E4OD transmission
@HughesPerformance
@HughesPerformance 4 жыл бұрын
Maximum stall speed is determined by whatever RPM the engine will flash to upon initial acceleration under load whether that be from a stop or very slow roll. You can transition to wide open throttle immediately at the same time of releasing the foot brake at 1,500 RPM, observe the tachometer while doing so, and the initial flash RPM is the maximum stall speed of your converter. You'll probably only notice another 200 - 300 RPM of flash over your current footbrake stall speed with that combination.

Our part number 25-30LHD torque converter would work well with your combination. This is our Pro Street series billet single disc 265mm model featuring an advertised stall speed rating of 3,000 RPM. This converter works really well in high performance trucks; offering a nice overall blend between great drivability along with a significant improvement in overall acceleration and performance as compared to an OEM torque converter.

Switch pitch torque converters can alter the stator vane angle (or "pitch") when the switch pitch feature is activated. The stall speed will increase when the feature is activated which contributes to faster engine & vehicle acceleration from a stop or low speed.

Are there application for using both a torque converter and clutch at the same time?
@mikeford963
@mikeford963 4 жыл бұрын
Not usually as an automatic transmissions clutches are internal. And the new "manumatic" type automatics simply allow to specifically select an individual gear. Actual manual transmissions do not use a torque converter, just a clutch. To have both would require a massive bell housing and a very complicated hydraulic system from the transmission. Also, why would you want both? The complexety of an automatic is enough for most people. Why add to that by throwing an additional fly wheel clutch to the mix.

Lock-up torque converters first began use by US domestic manufacturers in 1978. A lock-up converter features a clutch inside the torque converter that applies at cruising speeds typically around 35 - 40 MPH depending on the application. This feature was originally incorporated by OEM's to help increase fuel efficiency and reduce engine emissions. The aftermarket has since adapted lock-up converter technology to some extreme high horsepower drag racing applications.

In the early days of automatics, there were actually Chryslers with a pedal-operated clutch and a fluid coupling (a torque converter without the stator). Some shifted automatically between 2 speeds, but you had to use the clutch to switch between "ranges". They were probably less confusing to drive than to explain. The comments on this video explain it better than I ever could. kzbin.info/www/bejne/pl7al3yoqbuIo80 Also, VW had something called an "Automatic Stick Shift" in the 1960s, with a torque-converter, a vacuum-operated clutch and a 3 speed manual gearbox. The clutch automatically disengaged if the transmission lever moved so the driver just had to shift. Both of these seemed kind of kludgy, but they still could idle in gear, and could be driven in high gear with no shifting as long as you weren't in a hurry.

@HughesPerformance
@HughesPerformance 4 жыл бұрын
A steel stator is ultimately stronger than an aluminum stator. That being said, modern billet aluminum stator designs are incredibly strong as well. What it really boils down to is selecting the right stator design that will provide the correct flash RPM, torque multiplication, and converter coupling characteristics for a given combination. Correctly designed steel stators will typically (though not always) offer increased flash RPM, less torque multiplication, and greater converter coupling ability when compared to similar aluminum stator models.

Ordered a 22-20L 2000 stall Hughes converter for my 64 Chevelle, 700r4, 350 zz-4 eng with 20" wheels and it just doesn't feel right, what a waste of time and money. this was based on Hughes recommendations my understanding is that this only equates to about a 1700 stall due to it being an A/T. Unfortunately, the guy I spoke with was very irritated with my lack of knowledge of torque converters and I felt he just wanted me off the ph. i do however like and support their product.
