Im looking for a impeller upgrade for my gp1300 2005 with 87mm exit nozzle.

If you are only turning 7100 I wouldn't think you would gain anything by going to a 14/21 or 14/22. They would load you down too much if you do not change anything else.

Jetdave56 tell LT1GMC about what you did to your GP 1300 before you sold it (gave it away) HaHa .... if I remember, you were getting 75 MPH /GPS

...the other concern/question would be the difference between the Concord 14/21 and the Dynafly 14/20 (assuming that you're considering that in the mix). The Concord might be for the smaller pump...05' was first year for the larger diameter pump, but am not sure....?

Mmm oke...to bad.
So the dynafly 14/20 is my best option for top speed.
Need to go make serious tuning now then.
Hoping for good wheater soon and test Jims plate, its 5*C (40*F) at the moment

He'll need the Dynafly for that ski (155mm pump) 05-08....
Yep practically gave her away...As technology changes it effects everything around us....2 strokes just don't have the power and pull of a forced induction 4 stroke....Most members on GH started on 2 strokes at one time..need to spend alot to bring a 2 stroke up to date with the latest SC/turbo advancement to be on a performance scale...then,again there cheaper to build and repair than the 4 strokes..gas/oil expense on the 2 stroke just has to be turning people away if you expect to ride at least 2 hrs in a day...IMO
