B Pipe Vs. Dry Pipe

[WaterX117]

I currently have a Dry pipe on my SJ. What is the advantage or is there one with going to the B Pipe? Just seems the B Pipe is the choice of most.

I am fresh off of trying both so it is still fresh in my head. The B pipe produces a lot more bottom end on my mild set-up. I would say like 15% more bottom end or something like that.

My dry pipe seemed to allow my RPM's to go way higher too (so the mid and top were SICK!!) but I have no way to prove that.

I have run a Speedwerx dry, a blaster mod b-pipe, and a SJ mod b-pipe.

The Speedwerx dry made just as much power as both B-pipes, but the B-pipes had far better throttle response.

i had a riva dry on mine and it screamed on top, but i put a mod b pipe on and the bottom was much better. it had that instant snap to it, and it still has loads of top end. all of this is with just a head and prop.

if you run a dry pipe adding water injection will make a big difference. I am still not sold on b-pipes after running one this summer i think my type 4 hit better (with water injection of course)

B pipes are reliable and come with a lifetime warranty :biggthumpup:

Thanks Guys. My ski is a 95 SN with a single 44 Carb, Factory Dry Pipe, R&D Head and prop. Bottom is pretty nice, mid and top are real nice. Sounds like the B-pipe is definitely the way I need to go. Looking some real bottom end grunt.

Footholds next, check valve, reinforce hull, mod the hood and some hood straps. Any other suggestions for the next step to the power are welcome.

dry pipes like dual crabs, from what I have found playing around with some setups. don't be so fast to ditch your pipe there is a lot of life in dry pipes. Also the factory dry pipes would have the same warranty as the b-pipes wouldn't they?

b pipe has better throttle response
but the dry pipe makes more hp

 

[tom21]

yeah dude, did you not read the response? the gain or diff is minimal. my friend has a near identical ski - prop is only diff and he is just a bit faster top end and his ski hits right off the bottom- I still need some tweakin- so right now he is better than me and he has the dry and I the B. I would even consider a trade. maybe

 

[MADMAT]

The diff is big. I don't think your ski is tuned right if you have identical set ups except pipe. You should really feel the diff on bottom end.

I have run a dry with injection and without and it still can't touch a B on the bottom.

Although I always wonder what my speedwerx would be like if it had 190HP or so behind it.

 

[waxhead]

i believe people get confused as to bottom end and throttle response
my type 9 setup correctly had more hp than the b-pipe every where
but it didnt have the same throttle response as a b-pipe

 

[MADMAT]

Your right Wax. I should start saying throttle response. It is more accurate.

I have only had 3 pipes in my life. (well at least on a 701).

Type 9.

Speedwerx dry.

B pipe.

I would take the B pipe unless my goal was flat out speed. Then I would take my Speedwerx. That thing just seemed like I could never find the end of the power. It just kept pulling hard once you hit like 3500RPM's (guessing).

I hope that wasn't directed at me, my ski are tuned rather well. I spend a lot of time and try A LOT of different ways of setting up each motor wet or dry piped. I will try to get the most from each setup before moving to a different pipe, carb, ignition, PWM, ECWI porting....you name it combination. I just don't think the sun rises and sets on B-pipes because someone said it should. Tune what you have and save your pennies for gas and oil. /rant

 

[MADMAT]

I guess I was talking to Tom but really just thinking out loud.

I could never get my Speedwerx to have the same throttle response that my B has. I think I tried everything I could afford but it just never hit as good.

I would love to ride a SS set up with a speedwerx dry though.

 

[StandupEd]

Aside from power delivery there are several other advantages of the B pipe that make it desirable. It is the most durable by far, it is the lightest, and lastly has the lowest center of gravity. Consequently it puts the least stress on the cylinder casting. As the 61X is prone to stress cracks. The moment arm of a dry pipe with its double walled chamber filled with water tied to the lord mounts on the head is a huge strain on the lower casting on the cylinder. This is especially true for trying freestyle tricks and surf riding. If all you like to do is drag race then a dry pipe might have some value.

 

[SUPERTUNE]

I also like the 'B' pipes, when set up right they can't be beat for freestyle. I also mod them for my engine porting and engine combinations and really work good w/ton of reliability. Dry pipes do work and will make power, just not as suited for me.

the type 9 is an awesome race pipe i have found
it made my ski go bezerk

Just saying the bottom end on dry pipes not the best but when you add water injection it’s a whole new story.

People are confusing bottom end and throttle response
