I don't think so. All these results seem to be normal.

3 tokens search. More restrictive than the following...

> Hydraulic System: 791ms

2 tokens search.

> *draulic Power System: 1672ms

Initial truncature : scan all over the fulltext index

> Hydraulic Power Sys*: 1021ms

Right truncature, index scan from "sys" (your fulltext index is probably 
case insensitive). "Zys*" would have probably been more efficient here ;-)

> Hydraulic*System: 310ms (no results)

I doubt you have this token in your data, have you ?

> Hydraulic * System: 32768ms and more!!!

To be understood as :
Hydraulic [every token in the full text index] System
