lol
it has hyd tappets so online they say 5500 rpm max, but my oil pressure is far from standard, when it was built all journals were altered and pump work, upto full temp its 30 psi idle, as soon as i touch throttle it has 100 psi all the time which i guess is holding the tappets up virtually like solids anyways. either way it seemed happy revving high i just dont wana kill it.
the other issue is the mains are just 2 bolt, i dont yet know the limit of the bottom end ?
100psi will not pose a problem to the lifters and they certainly wont be like solid lifters.. Worst case with a pumped up lifter, is the valves will no longer close properly.
But no way in hell would I want 100psi of oil pressure in any engine when warm. So something isnt right there.
