Mmmmm, new billet, triple disc torque converters...Has anyone had much luck upgrading their stock torque converter? Pros? Cons? Just ordered a 6L90E Billet Tripple Disc Convertor 3200-3500
Thanks for the info... Im about 80/20 as I'm at the track usually every Friday night. I know the higher stall will affect daily driving, hopefully not too much, but I'm hoping it helps the top end and getting through the gears faster. I usually launch from about 1200-1500rpm on 17in Dr's. Best 60ft is 1.44 but usually around 1.50 So if I can load up a bit more and have it help elsewhere top end as well that would be great.Depends on your application. For me, who does 95% street driving and 5% racing, I like the tighter stock stall RPM (I actually have a 2,400 stall billet converter). However, having a billet converter with better lockup with more clutches is great. If you're doing more racing with a big tire and need to hit the tire hard, then a higher stall will help, but it's not as nice on the street, IMHO. And I've seen a lot of guys go fast (like high 8's) with a low-stall converter just rolling into it off idle. Granted, they're probably running a 418 C.i. stroker and a lot of boost, so it depends on your usage/combo.
Welp.... New converter in, new spindle bushings and trailing arms as well. 60ft not the greatest, 1.65 and 1.74 when I loaded up the converter too much. Also, only 131mph when normally I'm at 142 to 144. I'm thinking I need to tune the new converter from what I'm reading....My triple disc billet converter stalls at 2,600-2,800 and I find zero difference in street manners compared to stock. In fact I find the car more responsive. That being said, I don't drive the car very hard around "town".
I can tell you that it improved my on-track 60' by almost 2/10ths!
But that was tuning it before going to the track right? I heard it can hurt the trans if not tuned so not running again til able to tune later this week.We definitely tuned the converter when I installed mine. Trying to find the lockup sweet spot. We logged and tested lockup throughout the season last year.
Very first lap out with the new converter last year launching from idle, my wagon 60' 1.49, lifting the front wheels was an unexpected surprise!
Subsequent launches throughout the year, loading the converter, to try and improve my reaction times (1,500-1,700 rpm) were all in the 1.50-1.53 range, (when there was start line traction).

Yes, we tuned the torque converter lock-up before and made some adjustments during. The transmission was tuned previously as well.But that was tuning it before going to the track right? I heard it can hurt the trans if not tuned so not running again til able to tune later this week.
