These come from a 87 owner's manual, but I think they're the same as the years you asked.

Total gear ratio (includes the final drive)

Gear N/A Turbo
1 14.72:1 13.93:1
2 7.84:1 7.42:1
3 5.25:1 4.97
4 3.80:1 3.60:1
5 3.04:1 2.83:1
reverse 14.30:1 13.53:1


Final drive: 4.45:1 4.21:1



Have fun! How's the Murena doing? :cheesy:

I also have the speeds @1000rpm in every gear, do you need them also? they matter only if you have the stock size tires.


edit: I had everything well sorted using spaces, but this BB is too clever so it put only one space everytime I put more than one.... hope you still can read it.

Thanks Stefano. I also think that the gear ratios will be the same for those years. Do you perhaps also have a good drawing of the torque/hp curve I've found one on the internet but it's hardly readable. Need it for some speed calculations. Not much happening with the Murena, the latest was the installation of a 9000i gearbox but the project has been put to a hold because of "creative differences"

No, sorry. But you could try to ask for one at the C900 guys, the only difference between the engine you guys are using and the one in a T16 is the intercooler (I think) so the graphs could be similar.
