Active Autowerke | Generation 2 | Level 3 Supercharger Dyno Results

We are going to continue testing the durability of level 3 before it is officially released. So far things have gone well with atleast 50 dyno pulls in the last couple weeks, along with a full day of drifting.

Using a thicker headgasket would drastically reduce the efficiency of these modern engine's combustion chambers. It worked, with moderate success, on the old inline 6 engines, but does not belong on something like the S65.

great #s!

Torque at low rpms I like that. Power & torque is felt right away. I bet it feels great on the track exiting turns, to me that's where it really matters. Great product guys

Nice power!

Is this kit approved for extended track use for more than 20 min at a time? Because my engine sees a lot more abuse than the 30 seconds of drifting in that video.

It might only look like 30 seconds in the video but we did it back to back for about 2 hours and went through two brand new sets of tires. Due to the low speeds of this drift track and the fact that the car is sideways the car suffered greatly from lack of air flow across the radiator. All and all the car got hot but never overheated.

As soon as it hits the track for an extended time I will have some more answers for you.

Do you have any data logs for post compressor IATs, oil temps, and coolant temps? Drifitng is part throttle/full throttle/part throttle/full throttle/part throttle/full throttle..track work is a lot more full throttle.

Interested to see some data from extended track use. A graph with time on the x axis and IATs/coolant/oil temps on the y axis would be great.
