I've used the Z663ST for the last few changes on my L77, although with it stating "not for racing use", it has me wondering if that is because they assume high flow pumps may be used that will outflow the filter. L77's have high flow oil pumps. I might contact Ryco.
Probably more to do with the fact that race cars generally use an inline filter rather than the spin-on or cartridge types. I wouldn't be concerned - the oil pumps on those things would have a lot higher output than an L77.
Don't forget filters for our cars have a bypass valve that will open if the filter is overwhelmed by flow or blockage.
