The TRUTH about SJ drypipes

Ok, so I am considering running a drypipe when I get my SJ back together and I'm trying to weigh the pros and cons vs. a b-pipe. Let me know if I am missing anything here and please correct me if I am wrong about any of this.

PROS
- Can be had second hand for less money
- More all around power when tuned properly

CONS
- Takes more time to get aligned properly
- Need to run lower compression (I'm thinking like 170-175 on pump gas?)
- Need to take pipe off to remove head

I will edit this post with everyone's comments.

Less reliable than a b-pipe especially in surf (I am assuming this manly has to do with mounting)

I am convinced that with proper care during installation, dry pipes are every bit as reliable as B-pipes.

Not sure exactly why. I suppose because they turn higher RPMs than wet pipes, and they run hotter?

Not as much low end hit (this seems to be debatable because some seem to be able to get lots of punch out of these when tuned properly)

Properly set up, the hit is very similar.
The one drypipe I had (Speedwerx) outperformed the B-pipe by quite a bit, except on bottom.
But then I found out that I Ran my carbs way too rich, so now I wonder.

Any pointers? This could be a pretty good tech FAQ thread. There's not really much in there regarding dry pipes.

Prob depends a lot on which dry pipe you use too....

I think the b-pipe is pretty damn sweet... I dont know if I would go with anything else....wish there was some proof on certain setups... like actual graphs or numbers....

Seems like the majority of people have a setup similar to the FAQ first mods to your superjet.... on a ski with that setup would be the testing with the results that I would like to see...

ive ran all the fpp dry pipes
mostly the type 4
the only problems i had with it were about once a year the coupler would blow
i didnt use the top head mounts either just the mag had good bottom end and top
type 8 had amazing top end! but didnt clear the oem hood
i never could get the type 9 to quit seizing pistons
b-pipe the water inj screws seiz but hey if they are where you want them so what

My 2 cents, great power, cheaper up front used, like Matt said you need to be more carefull and thorough when installing to get the alignment set. But with that said, I have had zero pipe related problems, just more work if you take your head off often.

The Riva Freeride would be one I'd like to try out.... I would be really interested to see how it worked compared to a limited b-pipe on a limited superjet. I have read a little about them here and there.....

It seems that most people recommend the b-pipe.... if price is not an option... why would a dry pipe be better for freeride? Any specific reasons?

It might make more power on a limited, but not saying its better. You have to weigh cost vs the extra work. I have heard some talk about bad for surf freeride, but Blowsion just built Ross a nice ski with the dry. I'll keep mine until it has issues.

for flatwater freeride on a limited setup; I assume the b-pipe is still king if cost is no object...
