Cool.  This is something I will need to try!

From what I can tell it seems like it engages the clutch a bit also so it's already somewhat locked when you launch.

Are you doing this on a tune or the factory programming? 5.3, 8spd? When your launching are your hammering the gas to hit the stall or are you slowly building rpms. I'm just worried about the torque converter/trans handling this stress.

Everyone can keep dealing with this dumbass making assumptions or you can listen to people who have done it.

 

p.s. I don’t like you. Or your little 5.3 remarks let’s see your sweet rig

 

Probably a stock cookie cutter truck, with a leveling kit and 33” mud grippers am I right? Oh and probably a plug in afm delete and a pedal commander

am I close?

I was asking a question. I'm not sure what your deal is...

 

I asked you multiple questions too but you chose to ignore all of them. I was trying to figure out the difference in power levels between a 5.3 and 6.2 with your mods. I asked you if it was a 5.3, and you ignored the question.

 

I was concerned about the massive hole in your intake. Maybe there's something ****ed up the picture and I was seeing things. Because when you zoom in you can clearly see it. You failed to respond.

 

Same thing with your brother rig. I have no idea if there's possibly something else you guys did so that crankcase breathers aren't needed. No answer.

 

And now you come on here making assumptions and accusations about me based on what??? Unlike you I don't have pictures of my truck on here. And based on the fact that you didn't answer any of my questions, you answered them. So prove me wrong or shut the **** up

 

And yes I'm aware my grammar on here is poor. I'm the one doing typing

You never quoted me to make me aware you were asking me questions... so sorry they came off cowardly Because you were “trying to get me fired up” but weren’t really adding me to get a notification for your BOLD manly attempts at getting me fired up..

Its common sense, don't quote a post with pictures.

All of the above, the torque converter and transmission can handle up to 600hp (with a proper tune). The lock up and lock up clutch inside the torque converter are the weak points. Now that I removed all the limiters I get a little bit of squawk from the rear tires when I take off but it does it just fine. There are videos of people doing the same thing on turbo setups on youtube. It probably is putting some wear on the u-joints up front if I had to guess.

 

Its not uncommon to see a torque converter fail in these trucks around 50-60K and its because the clutch inside is toast (Its the stupid 100 +/- RPM judder when its locked up that wears it out). The material eventually enters the pump and then ruins everything. I've tuned out all my torque converter slip and raised the lock up pressure and I currently have 71K miles on my truck (It sees Redline daily).
