hi powered ppl 🙂
i got one Frenelsa f16 and now searching for one more for my hub dyno build.
this brake is rate for 2400nm at 800-900rpm, max rpm of retarder is 3800rpm.
How do i calculate retarder speed vs engine rpm? I got some result by deviding engine rpm vs diff ratio, keeping in mind that 4th gear is ratio 1:1 so if using 3.64:1 diff ratio i.e if engine rpm is 7200/3.64 that would be 1978rpm of brake. Is this correct?
Do you have do use two indectial brakes or they can be similiar in torque? If they are diffrent would there be some problems?
the brakes should be identical same for better torque, you could get it checked from some expert go kart mechanic and technician who could check exact rpm for you.
Hi, hope this help, I use telma brakes rated at 2800rpm for max. speed, any problems so far.
