Guigsy Posted June 10, 2009 Share Posted June 10, 2009 very usefull I've put together an Excel file which shows the effect of fitting various sized diff and gearboxes to the supra, it also contains a graphical chart showing the effect different tyre & wheel sizes and offsets effect both fitment to the hub and the effect on speed/acceleration. There are two main sheets on the file, Wheel size fitment and gear ratio calculator. Before it goes to the tech reference section, can some of you please review it and see if there are any errors or faults? Also, any suggestions for enhancement are welcome It took a silly amount of time to research the data and put this together, so hope it's going to be useful to someone Edit - updated with "final" version..

Homer Posted June 10, 2009 Author Share Posted June 10, 2009 Thanks for the reminder Guigsy, need to update this to the last and hopefully final version Its the normal code isnt it :- Crown Wheel Size: A (8'' - 203mm), B (8.7'' - 221mm) Differential Ratio: 01 (4.083:1), 02 (3.769:1), 03 (3.267:1) Differential Type: A (Standard open differential), B (Torsen LSD) Wes, you (and Digsy) were right all along, the above codes are correct I'll try and sort out the last version this week and upload to the tech section. Sorry for the confusion, my mistake entirely. Link to comment Share on other sites More sharing options...

DARETT Posted June 16, 2012 Share Posted June 16, 2012 It makes the car feel faster, and it could possibly be on the road, but will slow you right down on the drag strip Link to comment Share on other sites More sharing options...
Pig Posted June 16, 2012 Share Posted June 16, 2012 No good for what mate? 200mph run, nope but drag racing I was find IMO. I ran an 11.8 with 600 Link to comment Share on other sites More sharing options...
JamieP Posted June 16, 2012 Share Posted June 16, 2012 Yeah, i thought it might work better with the smaller turbo, was hoping it would be around 140mph in 4th, change into 5th will kill the time. Link to comment Share on other sites More sharing options...
