Cast water pump wheel? '02 WRX.... We have no issues running the regular steel fin water pump revving all the way to 9000RPMs.
Yes, I'm talking about the wheel. Instead of having blades, its a solid cast turbine. Check out the Article I posted the link to. The guys from Crawford talk about it being one of their trade secrets. I think I trust the word backed by CRAWFORD haha its a great article on the +/- of the ej engine, and some very respectable tuners give their 2Cents.
