Here's the absolute truth about building gearboxes... stop building them to the bloody limit.
Our biggest pet peeve is when a someone buys a box rated for 1000Nm, and then tunes the engine to make exactly 1000Nm.
You are just begging for it to go bang.
The golden rule? Aim for 70 to 80 percent of the unit's max capacity.
If you leave yourself that 20-30% buffer, that's your headroom.
That's what keeps the box alive when you're loaded up, hot, and pushing up a steep track.
If you need the ultimate, try our 10r80 gearbox package. We have customers with over 1500nm using them.
Build for reliability, leave some headroom, and you won't be picking up pieces of your transmission off the dirt.
