My 27ZX had around 580-590 hp and would bump 70.
I wanted to move to a step hull so I bought a 26ZX. It has a Young Performance 850 SCI in it. The best I have seen in it is 103 mph. It can get kind of crazy over 90. I have a friend that has one of the first 27ZX twin steps and his runs in the low 90's. It is dialed in.
How does the ext box work out. I pondered that with my 27.
