Torque Converter ?????
I drive a 00 verted A4 and I'm about to install a Vig 2800 or yank 3000. I'm wondering something, I know it will send me off the line faster but if I'm going 40 and gun it after the TC is installed will I get to 60 faster or will there be no difference?
Thanks Eric :cheers:

Yes, I would guarantee you would get there much quicker! On these So. Cali freeways it is hard to experiment, since they have new white unmarked patrol cars. Reminds me of the days back in the early 90's.

Re: Torque Converter ????? (wallstAL)
Hmm, I would have said the difference would be small, if any. Isn't the point of a higher stall to let the engine build to a better point in the HP/TQ curve before applying power to the wheels? At 40, aren't you already closer to that point, so the value of a higher stall is small?

Re: Torque Converter ????? (tscales)
With my 3500 Vigilante, I definitely feel the difference from zero to whatever, and can still feel the difference at a punch although not as dramatic. I admit I do not do a lot of "punch driving" but I say it will definitely help. I think most guys get the mod just for the start to whatever acceleration. I love my Vigilante and now that I have used my LS1_Edit to set the shift points and firmness, it is a blast to drive. Under normal acceleration, you do not know it's there. Best and first mod for the A4’s. Don’t waste time on exhaust, etc. Spend the same amount of money on the converter and install. You will not regret it!

The efficiency of the converter begins to matter more if you care about sustained high speed runs.

Re: Torque Converter ????? (jw02)
jw02, here are my 60 ft times with the converter (with run flats and with the BFG DR's). We have only gone to the track once with the DR's, but I am impressed with the 1.82 we got the first time. We are going to have to experiment with launch rpm's, but we are having so much fun with the LS1_Edit and EASE that launch techniques will have to wait.
Vigilante 3500 with Run flats: 1.91 to 2.20 (15 runs) 2.08 average
Vigilante 3500 with BFG DR's: 1.82, 1.94, 1.90 sec.

Thanks for the info. Mines an 02 A4, 3:15, Blackwing, Corsa Indy exhaust, run flats.. Best 60ft of 2.06. FLP Headers and Comp Cam going on Friday.
Sure like the sound of that 1.82 60ft! .25 at 60ft should be .40 at the 1/4.

Re: Torque Converter ????? (ericg320)
Seat of the pants, this converter is HUGE from launch! What a difference! When down-shifting, though, it actually softens the crisp downshift, making the car not seem as powerful.
From 40, when I punch it, my car is not willing to drop to first, so it feels pretty weak, both before and after putting in the TC. From 35, however, it's another story. The car drops into 1st and launches hard! But again, it did this both before and after the install.

Re: Torque Converter ????? (ericg320)
Yes, it will help you when punching it from a roll. Sure, the higher stalls will hit harder, but don't forget that they'll put/keep you higher up in the powerband as well. You'll be able to tell a difference (how much will depend on the stall) when going from a roll. As soon as you nail it, the converter will put you higher up in your powerband, so you'll be using more of your power. I'm sure you've experienced the severe lag that you experience when you get stuck in the bottom of a gear from a roll. You won't have that, at least near as bad, with an aftermarket converter.
Both Yank and Precision Ind. make great converters. We carry the Vigilantes at L.G. Motorsports, so call and ask for me at the store if I can help you out.

Re: Torque Converter ????? (ericg320)
If you want, we are going to be insalling a PI conveter in a customers car tomorrow. We should be done late tomorrow or in the early afternoon on Wednesday. I can't guarantee it, but I bet this guy would be willing to take you out for a spin so you can see how it feels first hand. :)

Re: Torque Converter ????? (ericg320)
In the spirit of "give 'em an inch and they'll take a mile" :blueangel: if you take these guys up on their offer of a ride, I suggest trying to get a before ride also. That would give you a much better baseline for understanding what exactly changed. It's hard enough sorting out what's attributable to converter vs gears vs tuning. Ideal would be rides before, after install but before tuning, and then after tuning (and again later after tuning has stabilized.)

Re: Torque Converter ????? (ToplessTexan)
Good point Topless, but I think we could skip the before ride. Just think Honda civic and that will give you a pretty good idea how slow my car is. Hopefully after the converter it will be a little better.
