"The solution for the spilling out the breather hole is to fill the unit with less than 4 ounces".

"After pressing Vortech tech help on the issue they tell me that for road racing in particular you need just 2.5 to 3 ounces to compensate for the oil expanding at temperature. More than that amount and it barfs it out".

I've only heard of one person's seals blowing out throughout all the people who seal both holes with shipping plugs with 928 upgrade.

Filling it up with 4 oz and then having it spill is pretty much the same thing IMO as filling it up with less than 4 oz it will stop when it stops.

You're right. They did recommend the exact opposite at one point.
Either 928 is lying out of their *** so they can make Vortech look bad, and that they can get more business from broke 928 blowers just for plugging both holes up, or they are telling the truth because they are finding out that tons of people are calling 928 and letting them know that plugging up both holes is actually working for them.

Not sure.

I guess we'll find out.

Either case, I'd rather blow out the seals than seize it up if I had to choose one or the other
