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!

Nice!!!

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?

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.

I think it is crazy how they can multiply power

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

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

Thanks

Great info! Thanks!

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.

Badass!

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

Sweet ride

Nice driving Karl!

Very Nice!!! Clean pass

Is this a full interior car with cage? Just curious, we are building a similar set-up right now.

Is that a complete stock bottom end? what transmission...what differential gear and what cam?

wow...you are pushing a little over 1000hp!!!

Sorry I see its a procharger..I meant what is the weight with driver?

wow...amazing...that was a stock lq4? what kind of power adder?

How do you like the TU2 cam? I've seen all of your combinations on this truck over the years. How do you like the current setup in the vid?

doing work man. congrats. hope to follow in your footsteps this spring.

I love that place it used to be a walmart
