Actually, I was thinking that 4.03 first gear would be perfect with a 3.27
rear end in my Sports 6!
Well, maybe! Still seems like first would be nearly useless behind a 2L six
and surprisingly Herald-like behind a 1600.
Some numbers, hopefully readable:
4th / 3rd / 2nd / 1st / Rev.
Vitesse/Sports 6 1600 (4.11:1 final drive)
4.11 / 5.74 / 8.88 / 15.42 / 15.42 -- overall ratios
1.00 / 1.25 / 1.78 / 2.93 / 2.93 -- gearbox ratios
GT6 (3.27:1 final drive)
3.27 / 4.11 / 5.82 / 8.66 / 10.13 -- overall ratios
1.00 / 1.25 / 1.78 / 2.65 / 3.10 -- gearbox ratios
**T5 on eBay with .81 5th gear (paired with 3.27:1 final drive)**
3.27 / 4.87 / 7.75 / 13.18 / 12.30 -- overall ratios (5th overall 2.65)
1.00 / 1.49 / 2.37 / 4.03 / 3.76 -- gearbox ratios
Spitfire 1500 US-spec. (3.89:1 ratio, single-rail gearbox; note that
three-rail all-synchro is almost the same)
3.89 / 5.41 / 8.41 / 13.65 / 15.00 -- overall ratios
1.00 /1.39 / 2.16 / 3.50 / 3.85 -- gearbox ratios
Herald 1200, Spitfire 4-Mk3 (4.11:1 final drive)
4.11 / 5.74 / 8.88 / 15.42 / 15.42
1.00 / 1.40 / 2.16 / 3.75 / 3.75
Triumph 10 and Herald 948TC (4.55:1 final drive)
4.55 / 6.62 / 11.20 / 19.45 / 19.45 -- overall ratios
1.00 / 1.454 / 2.46 / 4.271 / 4.271 -- gearbox ratios
For whatever the above is worth... ;-)

Herald engine with wings.
