Super Jet 155 pump in a Superjet

Yes you can. Wdk makes the easiest pump shoe to do this. My buddy has it in his sn. Just hard to get ahold of one of the pump shoes. I just put a 155 jet dynamics pump shoe in my brawler. It was a pain in the @ss. Lots of grinding and cutting on the pump shoe. If I did it again I would find a Wdk one for sure

whats the advantage over the 144?

My understanding is...

Larger diameter reduces pump pressure, increases the volume and the low end hit. The motor can rev faster while still pushing large volumes of water. You have a decrease in pressure and you loose power on the top end. It's the same idea as that behind putting in a stubby tail cone or boring the reduction nozzle. More volume = more GPM + more bottom end power = less top end power.
