Hello new to the website, So i have a 88 Jeep xj with a shift kit, Im from the west coast so we usually do sand drags in 100 yards i run 13” Paddle tires and 31” tires in the front cutt & shaved for better traction its a 4.2 stroker with a 250 shot of nitrous i was just curious if you can add an aftermarket torque converter for better launches. all motor I usually launch around 3500-3800 rpms When i spray its usually around 2500-2800. Im really curious to know as ive never really heard of anybody running aftermarket TQ Please and Thankk youu

 

Welcome I haven't seen a sand drag XJ yet so I am requesting pictures because it sounds awesome. Videos would be even better lol

That may be something that needs to be custom built by a performance transmission shop. But I don't know if it can actually be done. Of course they make high stall converters for popular transmissions in drag racing but i wouldn't call these popular. Make some calls to some shops and see what you can find out

How are you launching at such a higher than stock stall speed now?

 

Yea i figured i have tried a handful of shops in arizona and california but no luck no one really works on these thats why i wanted to try the forum out. And i really would not know how to answer that question the wiring is simplified just the essentials i would need (water pump,nos, ignition,etc) with a open computer i have a super big cam in it and it pushes through the brakes the torque converter is the stock ones they sell u at o reily or autozone with the 31s all around i hit about 5.20-5.12et on 100 yards in sand with nitrous its about 4.93-4.86et the fastest in the region currently is around 4.64 spraying way more than 300 easily but here are some clips for you guys

 

Another video similar build as mine with paddle tires

 

This is how mine sounds 4.2 Head work done, block workdone, Lq4 piston and rods, Cam, Eagle Special Crank, lifters and another few extra goodies

 

I was unable to find good aw3 convertors so i never did build the aw4 i have. I may revist that later since im tired of shifting gears.
