Re: diff ratio on turbo motors

[steven taylor]

Wardy, Im running a 3.9 behind my z18et and have been more than happy with it. Has great acceleration around the streets and is not revving "too" much on the freeway - not that it visits highways all that often. Anyways i picked up more than 4mph over the quarter mile after changing nothing but my diff ratio from a 3.54 to a 3.9, so id recommend sticking with it!! Steve. Mark Ward wrote: G'day Terry, I remember sone time back you were discussing the merits of diff ratios and turbo motors ie you suggested 3.7 seemed to be better for the performance of your car.  I was just interested in the ideas behind it.  I have a 3.9 in mine and while it works fine, it runs out of revs real quick in 1st, and has a fair engine speed in 5th on the freeway.  Would the 3.7 be more suited to me, or even 3.54 ? Thanks for your thoughts, Wardy  --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.datascribe.com.au/ozdatonline/index.htm http://www.datascribe.com.au/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.datascribe.com.au/ozdatonline/index.htm http://www.datascribe.com.au/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
