144 or 148 mag pump setups?

[Philip Clemmons]

I want every bit of performance from mine so its bored stock shoe to match the pump.

If it was out and not epoxied in that would be easy to do..................lol

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?

i dont notice any improvement with the cone, im running it right now, but im trying it for a few more rides then taking it out and seeing if i notice the difference

 

[masterblaster]

if your going to take it out,throw the mag 148 in there and see how that does

off topic, ported 701 that switched from a b pipe to a dry pipe is now spinning the prop down low. doesn't that mean it's got more bottom hit? just saying.....

That doesn't sound right... You sure it isn't carb tuning?

Torr..Luc runs a drypipe in his flatwater boat..........its basically an identical setup to Bogie


his surf boat runs a B..



I have a 144mag with a skat 12/17 sitting on my bench Ive been too lazy to install on my small bore Xscream motor

If you consider ripping your arms out of your sockets then sure lucas's ski has no bottom end !

 

[superwetbrett]

for anyone interested i will have a 144 mag for sale when it get here from skat

if i still had the mag 148 that would have been on my ski and would never have wasted $315 on a tbm "super" cone

Lucas's dry pipe 1000 makes its power from Mid to Top, it has bottom end, but the real power is mid to top which is what you want for flatwater.

The B pipe 1000 makes its power bottom to mid which is perfect for the surf.

I'm sure in the next month or two my ski will have the dry pipe.... The power you get from that pipe is unreal compared to the B pipe.

 

[Lucaumpits]

yea I forgot to say that, my set up is a 1000cc Pro package, flat water only, same set up as Bogie but alooot less compression and Josh is a 1000cc Freeride/freestyle edition, stock eletronics and B pipe

Idok don't be lazy, and install that pump, you going to wish had installed sooner

yeap , and thts why we use 145mm pump, we want to spins on the botton, and hits on the mid<
I mean it hits

i'm not to familiar with the dry pipes which one are you guys using

Your motor makes me want the dry pipe!!! I got the same carbs, Once I get the EPIC installed its going to be a dry pipe!!!! That power is crazy fun!!!!

see ya tomorrow bro

Me & Lucas are talking about the Power Factor Pipe

 

[Philip Clemmons]

Im no flatwater expert but how can you say you want mid to top on a flatwater boat? Going into setup waves is done at low speeds/throttle, so isnt that hit for a roll or backie considered "low end"?

I guess the other factor is prop selection.......................If you have a more bottom end hitting pipe, couldnt you stand to make it work with a steeper prop? We do the same thing with the blower cars....they make gobs of torque, so we gear them down (numerically) to work with the torq curve of the motor. Wouldnt the overall outcome be similar? Im not saying one is better than the other, but that there are some tuning choices........................

FWIW, I am into this thread b/c I am building a flatwater boat, and look to have it done in the next 2 weeks............................You guys have ridden so many combos I know your info is accurate, but riding style/preference comes into play too.

We should all be out riding today!

 

[Lucaumpits]

yes you may be at low speed toward your set up wake, but same time if you have a lower prop, makes your RPM be higher at slow speed, and you already "lost" your low end, and the mid and top cames

true story. tried another completely different ski today with a dry pipe. made a waterbox yesterday for the ski also. coming from a b pipe to the new dry pipe the ski has an insane more bottom and every where else. starting a new thread tonight about some research and combo's i've tried so far.

 

[Philip Clemmons]

So how would a 145-146 setback work on a 8 mil pump gas motor? I am judging by comments some think this is too small............................does that simply mean it wont hook up, or it will have less thrust on the bottom even if its 100% hooked?

On the other hand, if you put a 148 on say a 5 or 6 mil, many would say its too large......................What would the downside be to being too large? Would it overload the motor?

Also, where does compression factor in? Would PFF setup with higher compression be close to a pump gas B pipe of the same cc, say 8 mil, on the bottom?

I am building a pump gas b pipe 8 mil setup, with full specs and total loss, and am having hard time deciding. People seem to run both pump sizes in the low 900 range. Kinda at that threshold where I could go either way.

Someone please decide for me..........lol

 

[Aircraftsalz]

If your going that size motor & B pipe the 148 would work fine. IMO go 148 S/B mag. I hope to try the PFP soon with my 1000 & 148 mag.
