i couldnt really tell u exact car lengths, but id estimate about 4-6, depending.
(4-6 car lengths) . Even considering the top speed of about 240kms , its still a massive gain in accelaration time .

have you got a time for the 0-100 with the 4.77 fitted ?
It will probably slower to 100kph than OME car. Reason being that 4.77 car will need to change to 3rd gear at ~88kph, and after that will accelerate slower than OME to 100kph. Afterall, OME car will be in still in 2nd gear, which will have a fair bit more pull that 3rd gear (even with the 4.77 gear).

That has to be incorrect. an FI S2000 will have a hard time getting 6 car-lengths on an OME S2000, and that it over 400m (ie. up to about 160kph). To be 6 car-lengths quicker over 400m with just extra power, you'd need extra 50kW or so in an S2000 (with an equal driver).
Shorter gears do not give you extra power. Shorter gears will make the car accelerate quicker in some circumstances, but slower in some others. Though, same thing can be said about taller gears ... they'll make the car accelerate quicker in some circumstances.
ie. With the 4.77 gears you'll be slower than OME in the following increments:
1. 57 - 69kph
2. 88 - 106kph
3. 119 - 144kph
4. 154 - 186kph
5. 192 - 232kph
At the speeds between, the 4.77 geared car will be quicker. Though, which one will be ahead when you line them up depends on what speed you start, and what speed you run to.

Hi DavidM, thanks for doing that. I suppose that we could construct a similar comparison for stock Vs the 4.44 (if you don't already have one) using the figures given on the Turn Zero website - Is that how you did it?
