your top in power is greater but it will cost you a little bit in the mid range...

Keep in mind that midrange is what pulls the motor back up from being bogged down by loaded maneuvers.

I ran one of these and while it makes for great top end power, the engine doesn't recover as fast when you load it up.

I have one on a OS91HZ + SB18 and it gives you a bit more power. I don't see the mid-range affected. But some guys say that the SB18 has better mid-range than the SB20.

I'm waiting a 2nd T700 to use one on a YS91SR+SB19 combo.
