I just read that the ATI charger has no need for oil lines is that a good thing or is it bad? How big of a pain is it to change the oil in your super charger?

 

well im not sure about prochargers but on my buddies paxton you have to use a tool that paxton makes that is sort of like a turkey baister that sucks up the fluid then you replace it...im guessing this is what your looking for

 

No oil lines is a good thing when you are installing the supercharger. No need to modify the oil pan for an oil return and you don't have to find an oil source on the engine.

Once installed I think that it is better with oil lines. You have filtered oil. When you change engine oil you change supercharger oil too. You have a much more oil volume. The supercharger oil does not get any hotter than the engine oil.

A self coinained supercharger is much simpler. The only reson for oil lines is that the engineer desinging the unit did not think that a self contained lubrication would be 'good enough' ...
