Lextreme Torque Converter and WHP

Should be exactly the same. The gear they dyno in is locked up so the number will not be changed. Overall, in the span of a 1/4 mile (or whatever distance you want to compare), your car will lay down more average horsepower to the ground (so to speak) but not actually higher peak numbers. Best way to measure this? I say do a few 1/4 mile times if you're looking to quantify just how much faster your car is now.

Off the line will be better since everything below the stall speed (~2800 rpm) is multiplied. It should give you real traction problems with an open diff.
My rear main seal is shot and when I get the $$ to fix it I'll grab their torque converter too since it's all got to come out anyway.

My off-the-line performance is horrible. My wife's stock '03 GS300 Sport takes my car with no problems.

Cut the wire mentioned in this thread
It'll come off the line faster and shift firmer. That leads to longer trans life too, at the expense of being able to feel gear shifts. I don't mind it at all, and you can always wire a relay to a switch (or the power/normal switch) if you want to have it both ways. It takes away the totally smooth Lexus shifting and lets the trans shift like it does in the Supra.

I already had that wire disconnected, I even had the accumulators shimmed, and I had tightened up the slack on the kickdown cable. She still beat me with little problem......and STOCK mind you. All doing those two mods accomplished was blowing out my forward clutch and causing a tranny rebuild. Caveat emptor.

My thought now is that the forward clutch was bad since I got the car and that may be the reason I lose to her. I only bought this car a few months ago, so it's entirely possible the tranny has been bad the entire time and I just didn't know what it was supposed to feel like. A bad forward clutch does cause a huge loss of power. Just because the tranny shop said the cut wire and the shims caused the forward clutch issue doesn't make it so, I suppose. It could have been bad for a long time and I may just have been masking that fact with mods, not understanding the real problem and just assuming that the tranny was supposed to be THAT sluggish.
Either way, the TC should help a great deal. I would think even a stock SC400 should beat a GS300.
