RE: diff ratio on turbo motors

[Pete & Kath Liebig]

Hey Wardy,   Sorry, I don't remember what you were running engine wise, but if it is an FJ, CA or SR with an even close to standard turbo it should pull the higher ratios no worries. The turbo engines seem to like being loaded up with the higher ratios.   I am running a 3.7 with a near standard SR up front and it is fine. It has been to the drags a few times and first is still almost a waste of time. Any lower and I would have to try launching in second. It doesn't bog at all, and gets off the line cleanly using 2500 - 3000rpm. The most difficult part is minimising wheelspin on the change into second. Cruises nicely on the open road too.   3.54 would probably be OK too, but you may find it a bit of a disadvantage if you like to go to the track a bit...    'later PL -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Richard Clough Sent: Saturday, 17 June 2000 21:00 To: [EMAIL PROTECTED] Subject: Re: diff ratio on turbo motors I would prefer the 3.54 for two reasons. You can only get them in R180 size so they should handle the grunt. 3.7 is the stock 1600 manual ratio.  A turbo should be able to pull a taller diff as it has much more torque, especially round 2500 rpm, where your engine would be sitting when travelling at the legal speed limit. ----- Original Message ----- From: Mark Ward To: Ozdat Mail List Sent: Friday, 16 June 2000 20:21 PM Subject: diff ratio on turbo motors 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/ --------------------------------------------------------------------- --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/ ---------------------------------------------------------------------
