144 or 148 mag pump setups?

[masterblaster]

Im between choosing a 144 or 148 mag pump for a freeride 830cc stroker
What will a 148 do compared to a 144,what are some of the prop and nozzle combos you guys are using?

 

[Philip Clemmons]

I would think 144 on the "little" motors.........................

I'm tuning in too though....................

 

[masterblaster]

not many mag pump users here?

From what I've read so far... Most of the very few people who have mag pumps bought them under direct supervision of their engine builder. This unfortunately also makes the mag pump a less secure option for those without direct supervision and therefore the cost of a mag pump remains high and the number of people remain low since no one wants to drop $1000-$1500 on something that "might" work for them.

Can't say I blame them... I'd certainly want a good guarantee that my $1000+ will make things better instead of worse.

I think a mag pump (no matter which one) is far superior to a stock one. That being said, there are better choices for each application, and as you increase pump size, impeller choice becomes more critical as well b/c of the increased load on the engine.

From what I have seen, even some of the 1000 cc guys are running 144s or 145s with great success. The bigger stuff seems better suited for the huge motors, like 12-16 mil and 1000-1200 ccs.....................

I have no first hand experience though..............this is just what my research (on here) has led me to believe.

Unless you got an awful big motor, you don't need anything bigger than a 144. Plus, a 144 will usually be a lot cheaper because it utilizes the stock housing and wear ring.

I am leaning towards a 144,Malone uses a 145 and he has crazy power,but there are few ts 148 billet pumps out there on their motors and those seem to work really well also,just makes me wonder what the diff between them is,Im shopping used either way,so price will play a major role

i use 144 in B1 5mm PV 85mm and 148 in B2 with same motor.

 

[AtomicPunk]

i use 144 in B1 5mm PV 85mm and 148 in B2 with same motor.

and how do they compare?

 

[steve-uk]

i used a 148 in my rev hull with basically a b-piped/head on a 701 and it hooked up like tiger woods.....

however since having my team scream ss865 ( currently 826) pat advised me a mag 144 with a 13/19 prop cut back 3mm would be the ideal set up

i currently have a stock 144 with 14/199 skat and tbm cone.. personally the tbm cone i think is the biggest waste of money i have ever spent... my opinion

The 144 S/B Mag would be perfect for your set up. I think Chris (Jetmanica) has a few new ones. As far as pump size, Lucas has the XS1000 with a 145, but its a dry pipe so no bottom end & works well with his set up, My motor is B pipe (148 XS S/B) so the 144, 145 would not work due to the bottom end power a b pipe makes verse the dry pipe...

You can't go wrong with the 144 Mag pump!!!

Malone use a kawasaki mag pump

I'm running a Mag 144 and a 13/17 C75 impeller on my 946cc DASA motor. With the Power Factor pipe it works great and hits hard. Skis that hit harder down low (like big motor skis with B-Pipes) seem to need bigger pumps or higher pitched impellers. While big motors with more top end pipes (like PFF) likes the smaller Mag and smaller impeller because it lets me get the revs up before it really locks in and GOES.

Think of the impeller as a torque converter on an automatic tranny. MKIV Supras with big singles need higher rpm stall converters (i.e. lower pitched impellers) to get the RPMs up for a hard launch, while cars with stock twins launch pretty hard on the lower rpm stock converter.

I'm confused... If you're currently running the TBM cone, it's gotta be better for you than stock or you would've taken it out... right?

So whats the biggest motor you would run a 144 mag with, assuming its a b pipe total loss..........................and would you to a 145, 146, or 148? So many choices.....lol

Also, what happens to the ride shoe when going bigger?

 

[Lucaumpits]

it all depend, I would say 144mm for your set up but check with your builder, I seen 900cc stroker motors with 144 mag, didnt get even close to my Xscream 827 ss with stock pump, its all about have the pump and prop set up right
like I said ask you builder, I use a 145mm Setback, on my XS 1000cc, PFP and TL
you cant go wrong when you buy a magpump, and after that you will never go back to stock pump

good luck bro

I ran my XS 6mil/860cc, B pipe, TL (Stock SJ hull & Superfreak hull) with a 144 standard mag & it ripped, also ran that pump with my XS846 SS perfect set up... I think anything under 900cc 144 will work fine, after that if your running a b pipe you gotta go 148.

B Pipe big cc motor 148 Mag

PFP 900cc & up 145 or 148 Mag

IMO

Brian from Thrust has a 148Mag with his Dasa 930 Power Factor motor, boat feels great.

What I love about my set up is how well it hooks up. I can land in white wash off a reentry & brap & the pump just hooks up. Your never going to get a stock pump even close to the performance of a mag.

So what is needed as far as the ride shoe if you go with a 148?

Nothing, you can leave it alone or bore it to match. I want every bit of performance from mine so its bored stock shoe to match the pump.

wb800.so how do the pumps compare if your running them with sim motor setups,Id really like to ride those tj setups if they are truly setup for freeride?

steve.. why would you run a 144 stocker with a r&d cone if you have a 148 mag that worked well with a 701,it would work even better with a PV 860,that motor is pretty linear,it would prolly be sick with the mag in the surf,let us know if you try it out.

josh,surprised lucas runs a dry pipe if that is the case,arent you guys all about low end for freeride and freestyle anyway.hard to imagine a 1000cc motor with not alot of low end with ANY pipe really

Aron..good analogy,I went through that very thing with a auto big single sup and a stock twin 6 spd.stocker pump = street tires,mag pump = drag radials as well? sent you a pm also
