torque convertor January 02, 2007, 08:55:47 PM mine got wasted when I pulled the engine, rounded the nuts.I'm wondering if a convertor from a pickup would work, or any other cars that would have a higher stall than the stock Tbird AOD...Crown Vic maybe? Quote Selected
torque convertor Reply #1 – January 02, 2007, 11:46:50 PM from my link in the sig "DIY" ... tom has a few words of advice.......... I do like your primary question and would like to see an answer to it."""Torque convertersGuys here's the deal on converters. A higher stall speed increases you engine rpms(especially in the lower gears), so you in the power band quicker. Say you engine makes 50hp@1500, 70hp@2000, 95hp@2500, 110@3000, 125hp@3500 145@4000 etc. OK it has to lug its way up to get to the higher RPMs where its making more hp. If you increase the stall say 800 rpm from 1600 to 2400, then the off line acceleration is gonna feel like 90 hp instead of only 50(plus the torque is being mutliplied at a quicker rate which is really what a torque converters job is anyway). You don't want to go crazy with a big stall on a low revving engine, but about any stock car can be improved with a 500-800 higher stall.Now the lockup is a feature only on the AODs used in the Fox Birds/Cougs(and this is only for AODs, other OD trannys are different). What it does is provide a 60% lockup in third(direct drive), and full lockup in OD. What this means is there is only a 40% torque multiplication in third and none in OD. This is why low hp cars feel so lazy in the higher gears. The lockup feature can be deleted(non lockup converter) but for a 99% street car I'd recommend keeping it(I have) as the cruse ability will not be affected.
