I need some advice from some fellow members regarding the best mods for low end torque. I currently have a DD A4 2004 LS1 and I have done the blackwing, kooks headers, corsa exhaust, and a tune from MTI (they are awesome) and I am going to upgrade to the 3.42 gears in the next few weeks. I don't take this car to the track and put about 40 miles per day on it - I love having a lot of torque in the lower rpm band - any next suggestions? Thanks.
I went through the same thinking as you when I started modding. I love to hit the pedal and have the tires start launching nicely. That seat of the pants effect combined w/ pushing your back into the seat can't be beat.
The most noticeable mod is definitely the gears! You'll notice a nice change right away w/ the 3.42. On top of that, a torque converter can also make for some great changes as well w/ regard to the seat of the pants effect. You might even consider 3.73 gears to enhance you fun a bit further.
My setup you will see below in my sig, but I'm getting ready to add a 2800 vig torque converter to it as well. I did it in stages, but the first thing to do is the gears.
Maggie is very nice especially for low end grunt for sure. Just gets more $$.
Your driving habits sound like mine Also drive my vette forty miles a day to work and back. Also wanted my vette to have that low end torque so i opted for a used twin turbo setup. I wanted to keep the engine and drive train stock and the TTi Stage 1 kit was made just for those purposes. Drives like a stocker until you hit the go pedal, and then it's pure smiles
You can get some more from a correctly selected cam, that's exactly why I went with the cam I did was to boost the low mid-range while sacrificing something up top. I will be doing gears right after I have the car tuned from the FAST 90 install that will be next. The 3.90's (I have the MN6) are sitting in the basement just waiting
I think you are going down the correct path though, good luck with it!!!
