Its here again get ready Daftlad on your marks get set go....................................................................3:46 standard too high geared with C/R box, 3:73 the best with standard box, but equally good with C/R, but not quite as manic, 3:91 track day good match C/R box no crownwheels and pinions in the country 3 weeks ago.
await everyone else to pile in with agreement contradiction et al laugh

Who makes the crown wheels and pinions? And will all 3 ratios fit into the 3.4... diff housing without too much grief?

Wasn't sure which way to take the original post so I held back.....as long as I could!!

edited to add......I assume its your CSL at HHC at the moment - must have been hard to give that up - even for a Sag. wink

I used to Have a Tuscan S With close ratio box with 3:73 diff which worked very well indeed & highly recomended including for Road / Track day use. However I have a Sagaris now which had a normal standard gear box with a 3:46 diff which is a crap combination to say the least & considering the Sagaris has the similar engine as the Tuscan S or same! The Sagaris in comparison was incredibly 6 seconds a lap slower around Croft (1.42/1.36). Now my Sagaris has the close ratio box with a 3:91 Diff (+Nitron/Race) & is 3 seconds a lap faster around Croft than my Tuscan was (1.33) 9 seconds is a lot of track, & is 'EXTREMELY' entertaining & now goes like a rocket additionally can't believe it's the same car. The only draw back is that the top end is only around 155 & can just be maxed out on Hanger straight at Silverstone & that's with a 'dodgy' engine as well... To summerise as an allrounder the CR/box with 3.73 diff is superb, the CR/box with 3.91 diff is astounding especially when tracked...
