Both are K31's from Borg Warner... . of course they are hybrid.
For most a 66 is all one would need or want on the street. But running a 71mm compressor wheel while sledpulling is night and day compared to running a 66mm wheel.
The reason I brought all of this up is because it looks like there might be some "one off" or special Silver Bullet turbo's out there that people dont know about.
BrettWilliams said:For those of you that want to know some of the differences between a Super Phat Shaft and a Silver Bullet or a Silver 62. Turbine size on the SPS is 71mm exducer, Silver series is 74mm exducer and is a more aggresive trim wheel. This wheel represents the latest design turbine from BW.

BrettWilliams said:Yea I will try not to break more rules. I will be worried that I step over the line. It's a very thin line. Like my post here could be construde as solicitation. It's nice being back though. Brady
