The precondition for the overboost function is a demand for acceleration of more than 80%. The increased torque is available from as low as 1,500 rpm right through to 4,500 rpm. That means that the torque gain can be as much as 100 Nm compared to the BMW 135i.
Although in the first two gears the loss of traction limits the amount of power and torque that can be transmitted, more than 450Nm/295 ft lbs can be delivered from third gear on, and 500Nm/369 ft lbs from fourth gear on. When the DSC is active and maximum acceleration is called for, forward thrust is limited in first, second and third gears in favor of handling stability. Configuration is based on the optimum traction." M2 Technical Training: "On the N55B30T0 engine, the torque is increased from 465 Nm/343 lb-ft to 500 Nm/369 lb-ft (overboost) by a brief increase in the charging pressure of 0.1 bar above the normal charging pressure." |
Thanks, I have some more questions thou.
What is the normal charging pressure and how do i get it above it? Just floor it? Will it last 5 seconds similar to 1M and the RPM range?
