Tim,
I also worked out the gearbox ratios after I built my 8448 and got the
same results. I must admit your diagrams are a lot neater than mine!
Actually, I did my analysis all the way to the rear axle, which turns
1.5 times slower than the drive shaft. Therefore, I had to multiply
my results by 1.5 to match yours.
> I also like how reverse is in fact slower than first.
Me too. Also, 5th gear is essentially "overdrive"; one revolution of
the engine results in more than one revolution of the rear wheels (1.11
to be exact).
I've also worked out the gearbox ratios for the 8880 Supercar. I can post
them if anyone is interested.

| While disassembling my 8448 last night, I decided to work out the gear ratios from the engine output to the drive axle. I came up with the following (many apologies if this has been discussed here before). This is ascii art, so if you're on the web (...) (25 years ago, 14-Dec-99, to lugnet.technic)
