2005 A4 with these mods. Lingenfelter CAI, Nitto 275's, Glasspacks, Tune by Chuck at HPE. Best time 13.217. Wanting real bad to get to 12's.
Over the past couple of days I have done some major searches and have read tons of information on the 3.91 gears and new stalls.
From what I have gathered, IMHO, the thing I don't care for in the new TC'S is the lag time till it kicks in, where the 3.91's are good to go from the get go. I have read differing viewpoints about gas mileage.
I think the cost of a new TC, with a trans. cooler is around 1300 installed, but I am not sure about the cost of new 3.91's installed. I think a new 3.91 cost about 435 or so in the box.
I am thinking 1/4 mile timewise, each does about the same, maybe the 3.91 are just a tad better.
Thanks in advance for your help.
