My Red Top is running at 11lbs and its plenty.(Swapped in a t2871r during the swap) Still enough to get a little sideways around corners in the city...

Specs say up to 15lbs stock, but I haven't tried it..

The black tops are made with Denser Aluminum and shit, so I would only be pushing the boost passed 12psi on one of those. Especially if your mostly stock.
