KSFO - PHNL is just over 2100 nm so the 800 XP should be able to do it with very few issues. There is the possiblity of a wet foot print if you have pressurization problems. Without the performance manual right handy, I can not give you a complete anwser. The 800 has much better range than the WW2 or the LR36. And I have done that routing in both. It was not too comfortable at the mid point.
