The real xjr9 had a v12 7000cc for wsc and 6000cc for IMSA. The V6 supercharged was for the xjr10 and 11...and the xj220 (540hp closed to the 520 of out stunts version).
Here my revamp....remember LM is for Le Mans. With high speed and without chicane in 1989, the maximum speed was 405km/h.
So this version has a long gear ratio and the idle RPM is set et 2000.
On my mega. Enjoy.
