Only total of 2 V-belt driven accessories: alternator & A/C. On the turbo engine, no more V-Belts but serptentine belt system. Should free up some HP, not many but a few. Plus, I will be running 2 Serp belt systems: winter time will just be the alternator and summer is alternator and A/C. No more hassel dealing with V-Belts. EVP is very simple set-up and only using vacuum when needed (no more vacuum assisted brakes).
