Hi all just thought we would keep you upto date with a few things we are upto.
Firstly we have now completed the final design for and fitted our electronic valves into the C63 Dual mode exhaust project. They work a treat and the difference is very noticeable between sport and race tones.
We took the opportunity last week to get the car on the dyno to ensure that our system has zero loss between the two modes (some Valvetronic systems have shown upto 20bhp loss due to restriction when switched to 'quiet).
We were happy to note only approx 5hp difference between runs and this was mainly attributed to the extra temp of a second run..so all in all very happy.
We have a little tweaking to the current map needed but she put down a healthy 418whp and 382ftlbs
