Lockup vs. non-lockup
 

For higher torque applications....what is better and why?

and I'm not talking about ****ty :bs: converters like TCI and B&M. Talking about higher quality ones like P.I. Yank etc...


Curious to hear what you guys have to say.

All the lock is for is for better fuel economy, and I believe its easier on the internals as far as tranny life length. (dont qoute me on the ladder) Anyway IMO, I dont think it matters if you have alot, or not alot of torgue. If you have alot of torque, I'll assume you like to race it. I found that my lock up con. was costing me time at the track. I unplugged the torgue con. and picked up 2 tenths in the 1/4. I hope I was of some assisatnce.

On a turbo buick the opposite is typical, 2 tenths and 2-3mph gain is typical.

Tony, you know my opinion so I wont repeat it but am wondering if you've posted this over on turbobuick.com, turbobuicks.com, or t6p.com?

Actually it does, the more torque you apply to a torque converter the more it will stall(and therefore slip in high gear). In a car like mine thats putting out around 700lbs ft at the crank that torque can(and will)cause the converter to slip 10-15% or more in high gear. I dont know about you but to me thats alot of lost power. It's compounded by the fact that the turbo buick motor that both me and Tony run have a limited RPM band(preferably 5200-5500 and never more than 6000 in stock form)and a slipping converter causes you to turn more rpms for the same speed.

I feel like I repeat myself too much, I gotta stay out of your threads Tony :D

Steve, the reason why is because I already know their opinions. I just wanted to hear what others had to say :)

I really had no serious intentions of going with a non l/u converter.

And yes, you repeat yourself :D:D:D:D
