With a pulley and the big power increase you already have, your car has already lost a lot of cooling capability on a circuit. On a warm day, maybe any day, it will overheat. Have you tested it yet?
If you add anything else, it will get hotter.

It uses no pulley, stays cool on track and boosts power to 800+ BHP. You don’t need more than that on track except DSSVs, wide R comps and ZLE aero to beat anything but a 720s or similar, if you become a great driver.
