Torque converters......to lock or unlock?!?!?!?!

Just a quick overview of why more times than not on street cars that want to race I will leave their torque converters unlocked. quit worrying about what the dyno says and worry about what the time slip says.
Yes many high hp killers are now all switching to lock up converters but let's face it.....you dont have 2000+ hp in your car so let's not argue that point.
Take this for what its worth but this is what I've seen work best.

great video. I wish more people would see this because locking the torque converter will always burn up some clutch material and little by little will end up destroying your transmission. Think of the TCC as a wet clutch, if you use it, it is a wear item and will need replacement at some time, but also the used friction material goes straight into the transmission. It’s your choice but for my street strip I will leave all gears unlocked at all times. Modulate trans temp with a good cooler and don’t forget to change your trans fluid regularly! Great video!

Great explanation man, now it all makes sense as to why my car feels slower since I started locking it up at wot in 2nd gear.

Greta job Karl! Thanks for taking time for me on this. I am completely sold on this method after driving the truck unlocked.

Awesome explanation! Unlocked definitely seems like the way to go. That's one of the biggest benefits of automatic transmission. Having the torque converter. Like in the case of my Tundra 3.4l m/t... The automatic transmission version of my truck has much better power off the line. It's utilizing the engine's power band much better

Thanks for the video, I finally understand! Art Carr recommends non lockup on my car. I didn’t understand why, after hours of research trying to understand. Thanks for taking the time!

Totally agree, the TC must be unlocked before the HP & TQ cross each other, and it's is better to be locked right after the cross, this is to maintain speed in the beginning of the RPM band

What about HEAT. I run a 3500 stall with a Trans cooler. In a 72 Dart street car. 69 340 with 3:91 gears & a Gearvender OD. Safe?

Great info! Thanks!

[@theredwedge9446]

I think it is crazy how they can multiply power

[@jelenekoutdoors9023]

Nice!!!

Thanks

[@sambo92]

Badass!

[@barrykilts4506]

What’s the formula for figuring which stall speed to get including converter size and what’s the limiting factor for a road worthy vs street strip converter more for muscle car let’s say rather than a dedicated race car? I can add bigger or more coolers for a trip but most people don’t use perf.vehicles for trips.

Sorry but do you have the link to the video where you talk about Torque Converters and how it "cheat" the dyno run, please
