Shata,
Fear not my friend. Every full flow filter on the market flows enough to feed the engine with a safety factor built in. Run the full flow filter of your choice along with your bypass. Try googling "engine blown due to bypass oil filter." You'll come up with nada.
I have previously run an Amsoil bypass, Kleen-Oil, NTZ, Puradyn, etc. The size of the feed line to the bypass IS the restriction feeding the bypass, and some manufacturers have smaller input orifices than the 1/8" ID feed line they recommend.
Have fun.
