🔥 Bentley Continental GT Speed W12 6.0 – Custom Stage 1 🔥
A proper unit on the dyno!
This W12 came in for a custom Stage 1 remap, going from 580BHP to an impressive 669BHP on our 4WD dyno 💪
Even with our powerful dyno fan, intake temperatures were working against us. With a 6.0 W12 producing this much heat, temperatures started to climb and caused a few dips in the graph, holding the final figure back slightly.
On the road, the natural airflow through the front of the car is considerably greater than we can replicate stationary on the dyno, helping keep intake temperatures under control.
Tuning this one was also a proper old-school process! Both ME7 engine ECUs had to be removed and accessed in boot mode, with painfully slow read and write times compared with the latest generation of ECUs 😅
But the end result made it worthwhile — +89BHP from our custom calibration and a completely transformed W12. 🚀
