3.42 A4 gears question
What kind of gas mileage do you guys get, both city and highway? Also what rpm range do you run in OD @ 70-75mph? Thanks :cheers:

Re: 3.42 A4 gears question (magnetized)
if you currently have the 2.73 ratio, just multiply any driven RPM by
1.25 to get the 3.42 equivalent; or by 1.085 if you currently have the 3.15 ratio.
Not exacting, but will get you within... say... 20 rpm of what it will actually be.

I went from 21.6/26.5 to 19.6/24.5 when I went from 3.15s to 3.73s.
My rpms increased by about 400 at 75mph.
(Mike are you getting the C6 or the 3.73s?) :D

Re: 3.42 A4 gears question (TXSTICK)
No C6 for me. I drove all the way to the NAIAS in Detroit ; just to come back dissapointed.
I'm currently looking at the Kooks - high-flow cat setup for my 2002. I would like to improve the sound.

Unfortunately, I can't really tell you. Since I upgraded the gears, I am having trouble keeping my foot from smashing the go-pedal.
:smash:
PS. If had it to do over again, I would have gone with 3.73's.

Re: 3.42 A4 gears question (magnetized)
Do yourself a favor and get the 3.73's with a decent stall. I wanted my setup to be conservative, and was coaxed into the 3.73's after I was dead set on getting 3.42's installed. I am very happy ECS broke it all down for me and talked me into doing the 3.73's. Now I just wish I would have gone with a more aggresive stall.
