I have SpeedRiven HE in my own SL600 (exactly the same unit as on 55) and I can tell you that even in the hottest days you cannot see temperature going above 90C (before, you can always hear fans working in the summer). On the track there is a huge difference as IC temperatures are always low and recovery is fast. We have one HE in stock and I can take a picture on Monday if you want. Basically, it is at least 2 times bigger in volume than stock.
On the side note, on V12 (or if one is available for your vehicle) you may also want to upgrade intercooler pump and I have mine wired directly to the ignition switch. Pump alone will make a difference as well and if you have both, no issue running the car on the track till your brakes start burning

And the pulley being installed:
It will not make much sense for me to ship HE back to the US as customs is a pain.
