Just based on this thread we wont bother offering this. People already complaining about price. Honestly if people want this, others can take the time, and effort to offer it, or just make their own. Either way I had to pull the Valve cover off the MT car, the car was already extremely consistent in tge 765WHP range, it ran between 765-768WHP multiple times in row on the same tune. When the VC was off, I installed one of these. I got the car back together, and threw it on the dyno. First thing I noticed, even with plugged ports, dual catch cans, and a very robust PCV set up, we were getting quite a bit of vent out of the breather when there was no vacuum on the manifold, and before we had vacuum in the inlets, basically cruise conditions. I also noticed under spool, and full boost it was venting quite a bit of crankcase pressure evident by the visible vapor, and smoke being expelled. This is with DUAL cans pulling on the crankcase under full boost through the inlets. If you are running VTA etc, you will have much more built up crank case pressure, and one small VTA filter cannot possibly vent it all. In other words far from ideal.
The results were about what I expected, its very common to pick up power when removing Crankcase pressure, domestics pick up 40-50hp using a dedicated vacuum pump to purge the crankcase. We picked up 8-11WHP, and on the same consistent 765-768 map power jumped up to 776WHP. The power is nice, but having another layer of PCV protection is more important in my mind. We will put these on all our N54 projects, and GC installs we do.
