Today Its about 230 km/h as fifth gear has 1.0 and engine cuts rews at 6300. If I change to 0.86 on fifth it can reach around 263. I´m changing the valve springs and the head is getting ported, so the top speed will increase anyway.
But I´m not after top speed. The old box had 0.87 on fifth and was great on the highway, and first vas 2,66 and was nearly perfekt. The BMW box has 4.21 on first! wich makes it nearly useless.
The close ratio gearkit from gearboxman has 2,57 on first and 0.87 on fifth.
Wich means that on first I can reach around 100 km/h on first at 7000 rpm.
Wich is nice when launching from stand still.
