I have a GTX Ltd. -98 and I´m thinking of buying a Solas Dynafly 13/19 impeller, how mutch top speed (or what top speed) and acceleration will I gain from a worn out original impeller ?
I am not an expert but I will give you my opinion. I think that with a worn impeller you are losing a lot of power and speed, but when you put the new one on you can gain 1-3 mph from what I read.
