Default Need to Know RPM Ratio's for A4 w/3.42's - Will help my decision!
I need to know the RPM ratio's on an A4 with 3.42's, I currently have 3.15's and @ 70 MPH it is 2,000 RPM's etc.

70 MPH w/3.42's = (If at all possible MPG too! w/all MPH)

75 MPH w/3.42's =

80 MPH w/3.42's =

85 MPH w/3.42's =

Please no guesses if at all possible. The 3.42's is the way I want to go and I want to retain decent fuel mileage

Any and all information is very appreciated! Thanks fella's!

Thanks,Matt

Matt, from a table that RPM Transmissions shared some time back:

70 MPH w/3.42's = 2100

80 MPH w/3.42's = 2400

90 MPH w/3.42's = 2725

Thanks Dick,

Now are these for a C5 A4 or the C6 and if so are they the same ratio's being either a C5 or C6?

I like the nratio's and will get the 3.42's

Thanks,Matt
