Tht is a goodd thread, let's keep it like that So Aaron tell us the pros and cons of that thing cuz at 345 usd I would prefer it to be a hit, not a miss....

I tried one last year. It might have made a tiny difference in hookup or keeping th pump loaded. But then I tried a real mag pump and it was drastically better.

The good: it's 1/4th the price of a magnum pump

the bad: it's only 5% as effecive (being generous here too)

verdict: save your money for a real mag pump.

Agreed. I bought one earlier this year. I ran it for a few weeks with my ported 701, taper bored nozzle, 9/15 hooker, and total loss. I could tell a difference but not much so I still pulled it out and sold it. The one thing I noticed when I had it was that the pump unhooks violently when you're on that edge and very unpredictable. Sounds terrible like you just sucked something through the pump.

spend your money on a real pump. get a mag pump. the tbm is not worth the money.

What really sucks about this is that on the SXR it works pretty good. It's the one thing I wish I had on my SJ, the ability to hook up

 

[Don 79 TA]

i agree on the SXR
really works nice on her SXR
i was thinking about it for my SJ, but i'll probably just get a set back mag for the extra bite

How many people change the prop to account for the TBM cone? I could see if you simply added the cone to your existing pump prop combo that you may be disappointed, but if the prop/cone combo was done properly I would expect good results.

Just wondering if the cone is being given a fair shot.....I know it works great on the Kawi pumps and it's hard to believe they're that drastically different.

I don't consider changing props part of the bargain. If you have to buy a $350 pump cone and a $275 prop, you're already $625 into a half arsed mod. Meanwhile if you sold your stock pump and prop and used that $625 plus the money you made from the pump and prop sale, you'd pretty much have a mag pump with a prop. Gotta think value for money IMO and at what point are you polishing a turd?

i have one and a properly matched prop and it works awesome. i have seem people put them in their ski with the wrong prop and say they are . i got mine from legdrag with a c-75 skat and its night and day.

Here is my thread/review with lots of opinions on it too. Some good reading:

Have you tried a mag on the same setup?

 

[Polish jet pilot]

I think the results depend on the exit nozzle size and cone combnation..if these are not mached the pump will not work in most efficient way ( I bet size is tuned to rpm and load)...??

 

[Matt_E]

That's true for any pump and pump mod.

 

[D-Roc]

i also think that is part of it. i wouldn't buy just the tbm alone. i only bought it with a matched prop after i was finally making more and more power with my motor and not seeing more punch out of the water. i knew my motor was running stronger and stronger but not feeling it. people that have a well matched prop to their motor and add just the tbm propably think it is a waste. people like me that spent each seasons budget on hp for the motor and never adjusted the pump/prop during those times will see a big result.

 

[Matt_E]

The whole driveline should be matched after each big upgrade, imho.

good points on the SXR the props are all large hub so with all the small hub SJ stuff around, that is probably part of the issue
