skat trak mag pump

[felonyryder]

Hi,
I am thinking about getting one and was wondering what the difference between set back and regular style pumps, also the 12 and 14 vein. It is goin to be put in a super jet that will have a built 760 in it. Or is one even needed for this application?

I believe you get more top speed with a set back. I have a 12 vein set back in my Superjet with a 760. I changed back to the stock pump with a 13/17 cut back and I hardly notice a difference.

Mag's work well but are heavy. We run a great set up that works better than the Freeride 12/17 swirl or the Solas 13/17 and works like a Mag without the weight.

Robertg- You should of notice a difference. Maybe too big of impeller. What impeller are you running in your mag?

I am running a 14/19 with a 85mm nozzle and a WW cone. I noticed the Magnum really hooks up well over choppy water going WOT. I rarely go WOT, I usually put around at about 20 mph. It has a lot to do with my riding ability and style.

I may try the pump in my Blaster but I need a longer drive shaft.

So am I reading this correctly? You get almost the benefit of a mag pump but for 20% of the cost? Sweet

 

[Idok]

now the real question is, do you want mag pump performance for freestyle...

for flat, I'd say NO



for freeride, I really enjoyed being able to maneuver/hookup even in monster matanzas whitewater.....


but you can definately feel the azz end of the ski glued to the water with a mag setup.......and Im talking pure suction

No, you are not reaing correctly, it's about half the cost (impeller and TMB cone is over $500).

I have tried this setup (not from Legdrags, actually it was suggested to me by Pat Bogart) and it is impressive. I have ran The TBM cone both with a 12/15 concord and with a specially pitched 12/15 75mm hub Skat swirl.

Of course my altitude plays into this, but I'd have to say the trusty concord is super strong all around, with a slight slip right off idle.

The Skat big hub seems to really shine in the midrange and pulls a little harder up to top speed - with so much loading of the pump that it brought to my attention a lean spot in my carburetion (in the mid-to-upper RPMs) that I was not experiencing with the Concord.

My advice for this setup is... have a lot of HP! And you will love it!!

why do you think Ive never asked to ride your, pauls, etc......i want nothing to do with lamey power

wanna sell that magnum?

There is a lot more to a magnum pump than just an increased hub size. The stator section with increased veins is all stainless steel . The veins are slimmer. It is only 140 mm wide when stock is 144mm. I run a magnum pump with a 12-17 pitch and I can cruise right through the white water. Next time I have it out I will weigh it. I can't imagine it would be more than a few pounds heavier than stock. I really couldn't tell any difference in accelleration or speed from my stock pump with stubby cone and 13-19 solas concord, but it definitely hooks up in the chop and white water. That is something I love when riding the beach break.

agree with half of this. I had a concord 13/16 cut back w/ wet wokf cone in stock pump and noticed huge slippage on very bottom. I instulled a 12 vein non set back w/ 16/21 and it hooks and stays hooked 75% better. But it is ALOT heavier then the TBM / concord set up.
The TBM / skat swirl or concord is much better bargin for $$$$$ than the MAG.
Keep in mind I am running 86mm flattop w/ 210 comp. and 48mm full specs.
If you dont have the power to push a mag the only gain you will get is a better hook up in rough water.

 

[Mile9c1]

I think the 140mm Magnum units are about 7-8 pounds heavier than an OEM setup. I weighed mine last year but have since forgotten the exact figure.

 

[waxhead]

i have a magnum in my ski
i have just changed it for this very setup you are talking about
i was hoping people wouldnt talk about it as its on my race ski and it was my little adavantage
i will let you know what the difference is when i gt the ski going again in the next week

I have a couple other people that sent me pm's saying they were interested in it also. I don't really want to sell it but I would trade it for something interesting.

 

[superramjet]

is it a 144 or 140?
