Crankcase Ventilation

we have air pumps for emissions. pumps clean air from the exhaust. low volume however.

as soon as oil hits them they burn out. some people try it and “like” it. imo, it doens’t accomplish much.

imo, if you can’t fit a real belt driven pump, and you dont have a 100% full time 100% FREE FLOWING exhaust aka dumped headers or like 5inch unmuffled, just run a nice breather setup. you will always be compensating somewhere

TFers have used the pumps for a while now with no problems. ~440 whp, >2 dozen track passes, doesn’t have any dipstick blowout any longer. :gotme:

Hobbs switch powers the pump up when in boost, when not in boost its effectively a breather.
