Torque Converter mod

LiftedFordGuy · 12-28-2010, 04:44 PM

Wondering if it would be worth the 800 bux to send my torque converter to importperformancetrans.com they claim for 729.00 they will "ncrease performance and reduce ET by .5 to 1 full second over a stock converter"

what that means I dunno but someone had told me it would be a good idea and give me some gain. Just thought Id share this and see what everyone thinks, Thanks in advance.

most reputable transmission shops can modify a torque converter. I would check around before spending that kinda of cash.

here is one I pulled up in about 3 minutes that offer modifying one for $395 requiring your core. I know it says GM ford etc. but the link show's imports as well.

Yeah try to find a local guy. toomnymods used the company you linked too (IPT), and had a bad experience. He had a local guy open it up and said that they didn't do anything special to it and it was questionable whether they actually used and upgraded parts. Toomnymods also did drop .8 in the 1/4 mile with his stall convertor, but he had cams. It probably wouldn't be worth it IMO without cams

sweet thanks for the input fellas! Im waiting for Jim Wolf to reopen from their vacation break to buy my cams =) I will ask around for a good local shop that can do the same.

Wondering how much I would want to raise the stall speed without messing with the computer?

Consult with UpRev what you want to do. Stall affects "calculated load value", iirc.

LiftedFordGuy · 12-31-2010, 10:28 PM

Sounds like a good idea, thank you!

defiantly check with a tuner for the tcm control.

most stock stall converters can only be modified a little 800-1000 rpm higher (usually by changing the blade geometry of the stator/turbine blades) more than stock before becoming failure prone, eg higher fluid temps or other issues after that it would have to be custom built.

LiftedFordGuy · 01-01-2011, 12:10 PM

ummm didnt even think about higher fluid temp, be a good idea to add an aux trans cooler? Some times I hate weekends, gotta wait 2 days for uprev to open AGH!

darklifter · 01-01-2011, 10:49 PM

I never had any issues with the "stock" torque converters that I had slightly modified (GM) the stock trans cooler worked fine at keeping fluid temps down

Personally I would never do a higher stall torque converter again on a daily driven car/truck they feel.... disconnected, now a drag car/truck YESSS!!!

If your looking for the .5 to 1 sec. off your 1/4 time. juice it!

now thats a good site you posted!!

Been thinking about this for the past year as well... but taking one step at a time... installing soon is my transmission upgade kit, waiting on front and rear 4.10 gears, with distant hopes for JWT cams and TQ converter upgrade...

LiftedFordGuy · 01-05-2011, 09:52 PM

been thinking as Im looking into this mod, Id probably be better off waiting until I get all my engine mods and shift kit done to build a TQ converter and build it from a dyno spec rather than guessing where to build the power. Thanks for all of your input keep us posted if anyone ends up doing this mod cuz I am VERY interested to hear about it!

I haven't heard of anyone who has upgraded their TQ converter yet either, but I would imagine that the big $ peeps and trophy Titan's have custom coverters... Just from my own brainstorming, I'd imagine this would probably be one of my final mods to do... since, I plan on keeping my T until it dies or gets destroyed, I will be buying a custom TQ converter, but the realistic time frame for that probably within 2 yrs... too many other performance mods before this...
