Sprag vs. Spragless??

Below stall sprag or spragless the stator is inactive, at this point it acts as a reactor redirecting the oil from the turbine onto the pump, this is how torque multiplication is acheived below stall.

The concept of one way clutch is that when the turbine picks up speed turning the input shaft, oil is redirected onto the outer edge of the stator, and the stator can turn the same direction as the turbine above stall. As the oil ,turbine, pump and stator become one, the output shaft is closer to being 1 to 1 with the turbine turning the input shaft at the same rpm's or close as the pump, stator, oil and engine rpm. Being the one way clutch allows the stator to turn as one with the entire unit, the windows between the stator fins are more open.

I think when the engine is rung out with the torque of the engine diminishing at a higher rate than the rpm is increasing, the open windows on the stator with it's capacity to turn as one with the unit, creates less drag. I think this is the phenomenon that has sprag converters dominating comp eliminator 1/4 mile racing. They coast better as power is removed / diminishes at high rpm.

Where is a centrifugal converter utilized I have never come across one ?
Centrifugal converter .... Is that like a weedeater clutch ?

One is sprag, one is spragless.

If you could put the best attributes of both these into one, you'd have a converter that is 3 to 4 hunredths faster. That's a lot in a 16 car field of like fast cars.

It's not something you'd wanna bracket race though, and as the two converters stand alone, as is....

The TSI spragless is the faster of the two. Just slightly though.

I'd have a hard time letting go of the PTC, it's a bad dude 370 pro tree converter. $800, I might think about it. Maybe.

My TSI 806B was 12th in line for paint yesterday, when I called to check on her at 1pm.

B for badazz. Smile

Think it'll make it from PA to Florida today?

we all sure hope so , otherwise you wont be the "quickest and fastest 3200 pound red and black 69 Nova with a track one headed SBC... and a windshield smudge on the passengers side , and a nick in the paint behind the right rear wheel " this weekend

Just call Hughes and tell them what you have and what your goals are and they will help you. My go to guy there is Stephen Hughes and he has really helped. I told him my dyno numbers and what I wanted and he nailed it perfect FIRST TIME. I did not have to take it out and send it back 2 or 3 times. Talk to the professionals not the internet wanna'be. I am not saying anything bad about other converter companies but I have been blasted before because I did not buy my converters from XXXXX company and yet those same people have had to send their converters back 2 or 3 times to get it right. One thing you have to give them good information dyno numbers etc to get good results.

I have heard some say the Spragless will be slower, mine did not lose anything when I went to Hughes spragless. And it is very consistent.

Regardless of who you choose to get your converter (Cam, Heads etc) call several companies and get their recommendations and choose who you think is best for your needs. Try to learn what they recommend and why and that will help you make a good decision.

"Dunning-Kruger Effect"
-a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

806b is for 383 sbc. not mine Cupcake.

Now cupcake listen up.

sbc 23 degree n/a, 3200 lbs, 10 x 28 tire, out of box Brodix or AFR.

Now cupcake, don't be jealous because I can do what you pay others to do because you don't know how, and still can't be fastest, ok cupcake?

Also cupcake, go find another like my Nova faster n/a.

You can't cupcake. Smile

It's a dud, sbc n/a 3200 lbs, all steel on a 10.5 x 28 bias tire, out of the box Brodix T1 heads.

I'm trying to find one like it, equally as slow.

Why, you got one? Smile

I put together a new sbc in 2017, using 90% of pieces I already had laying around.

New transmission, the same.

It dipped in the 5's, off the trailer new, as I predicted beforehand, after looking at the observed stall rpm.

Converter will tell you all about your power, once you have an observed stall on any given torque converter, based according to X amount of power.

I do all my own stuff , and I'd fall asleep in that turd of yours ... I believe our last time slip said 3.87...... not 5.90's ... so when you get that turd to run 6.0 in the 1/4 mile look me up ....But I'm not a red 69 N/A nova ....so like everyone elses stuff on here its junk ...I guess I'll be Cupcake , we'll just call you TWINKY

Performance is relative, there's a bunch of turds going 3.87. A shyt ton of em.

So far you can't find anyone else, not one sbc 3200 lbs going 5.90's, but don't feel bad, I can't either Cupcake. Smile

If you were the only going 3.87, I'd be the first to say damn, CupCake is a bad MotherTrucker.

But that's just me, how I look at it.

Is that not normal?

I might even say, I bet it has a TSI spragless converter. Smile
