Most of the brake horse power values given by the manuufacturers is a whole bunch of useless information.

I don't know where you live or what you have experienced so far, but generally the ball bearing ABC 46's are the better ones as far as hp goes. Some of the leaders, but not all of them, are OS46FX, Thunder Tiger Pro46, Super Tiger GS45, MDS48. GMS47,Tower pro46, Magnum/ASP/SC 46XLS (latest version). Enya CX50, and Irvine 53. These engines have different prices and the quality varies somewhat between them. It's likely that you would be very happy with any of these. They all have about the same power.

The best determination of the best engine would actually be your preference.

Also, You could possibly enjoy a different engine if you became accustomed to it and it served your style properly.

However, the standard of comparison is the OS46FX.

There will be more entries on this thread proclaiming a certain engine junk or that only a certain one is worth considering but the choice is yours.

Good luck,

Jim
