Freestyle Stock 144 pump verses stock 155 pump for my motor swap? Pros and Cons

[Sasquachcrap]

Ok for now this will be going in to my square nose. Eventually hopefully when funds permit into a bob g3. I have a stock 650coming out and a dry piped 760 going in it has the cylinders lowered and will have a Ada head on it with around 190 compression. Stock duel 44s, stock ignition (61x), riva intake grate and groovy ride plate. I have the donor wb2 that all the parts are coming out of. But I wanna know should I stick with a 144 pump and a 9/15 hooker? Or throw in the 155 pump and prop it as nessasary. I know I've read that the 155 is a bit to much for a 701 but the 760 had that pump in it from the factory and it will be in a LOT lighter hull then the wb2. Also after my mods I would think the 760 would be that much stouter. Has any one done this? What were your thoughts? I would have to buy the pump shoe and the prop for the 155 To make it work. Which isn't to bad if it will give me the big thrust I want.

You're going to have to do more than just buy a pump shoe. The 155 pump won't just fit - there would be extensive glass work required.

I like the name Squatch master! Welcome to the X =)

Thanks pro-pulsing. Matt say I get the glassing figured out. Proformance wise will it hit hard or load the motor to much off the bottom. Ps if you get a chance to chime in I have a thread about my motor build and home porting job. I really liked you home porting write up.

oh I have not done any porting myself in quite a few years, so I don't think I'd be much help.
People have put these pumps into Superjets. There's a fella on this board that did it, but I can't recall his name.

some guys around here played around with stock 155 pumps, nothing beats a mag pump, why not do a 148 mag and be done with it?

 

[Sasquachcrap]

Mainly the cost right now. If I had the money I would rather put it in to a hull. What ever I put into this Superjet hull can easily be swapped into a aftermarket hull down the road.

^Honestly then run what you brung... stick with the 144 pump...

Id stick with a 144 till the bob. And a 760 wb motor doesnt have the bottom end punch thst a ported 718 or 726 would. A solas and 9/15 zwill work nice, and when you get in the bob the weight loss will be very noticable.

Well I was going to swap all the shafts and bearings around to just do a dry fit to see how It looked but.......... I blew the back of the 155 stator out pressing the bearing out the WRONG way.:doh: So I am sticking with the 144 pump.
