The difference in pipes relates to the sonic wave returning through the exhaust pipe. Tuning an exhaust is all about timing it right. A wet pipe injects water into the flow of exhaust gases cooling and slowing the returning sonic wave speed increasing bottom end and acceleration. A dry pipe runs dry inside and benefits more to an engine with more exhaust duration providing more torque towards mid to full throttle. It is all about tuning to your riding style.

So is it a one time tune once it is tuned for the engine it is mounted to? or is it something that needs to be retuned on occasion?

Tuning is never ending. You must try many variables to come up with a combination that you like and see what works for you. Impeller pitch, nozzle diameter, jetting compression, port durations, ignition etc... all have to work hand in hand. It is the sum of all parts.

So for someone running a freestyle ski, assuming they want more bottom end grunt, a wet pipe would be a better choice?

Tuning a dry pipe is it done by sound, is it something that can be learbed fairly quickly?

Don't let them get on you to bad, they just don't understand the financial opportunities currently available in Alberta. I was working with 24 yr olds that were making $400K a year. They drive $75K trucks, own 3 houses, numerous blown sleds, bikes, quads, choppers and everything else, you name it. So, what's a full blown freestyle jetski compared to a fully dressed Harley or a 385HP Turbo'd Sled? As far as needing talent to ride a ski before money, yes this is usually true but at the same time alot of natural riders are hampered by their ski, this may not be your problem. I have a buddy that will dominate any motorsport right out of the box and he would do exactly what you are talking about and be a top 3 rider within 2 years. It's what can happen when you are raised with motorsports. Play your own game Chris.

Can't wait to see what direction you go and what you build. :bigok:

Yes ,wet pipe for bottom power, but you can set up dry pipe for bottom too with water injection. But dry pipes heavy and you need to use girdled head if you does'n want to crack you cilinders. Girdled head use additional hardware to bolt it to cases

OK Guys...
Team Scream was MY racing engine building business.
xmetalworks.com was Patrick's business.
After 10 years of friendship and relationship building ski's together we desided to join both companies together. This is how we became X Scream Inc.
So when you refer to Team Scream, we are now X Scream Inc.
when you refer to xmetalworks.com, we are now X Scream inc.
Because of the brand recognition we have with the web site, xmetalworks.com is the company website.
On the wet pipe, dry pipe debate...The newest dry pipe on the market is the Power Factor Products pipe. This pipe offers more horsepower than any previous dry pipe for a Superjet.
PFP pipe does require a very specific setup to match the pipe, the Factory Pipe 'B' pipe is very user friendly for just about every kind of Superjet power combination's.
You just need to pick which one is more suited for what you what to do with the ski power level and riding style that suits your needs.

seems as if you are getting more of how it works.. a wet wipe/ b-pipe is simple, clean, tidy... make good power.. all around the best pipe.

If you have a big power (1000)cc motor. As you think you want for freestyle
a dry pipe set up will provide more hit all around if set up correct.
a power factory dry pipe is the way to go.. you will have to run a smaller gas tank. but most real flat water guys want less weight and do not care about ride time with the bigger tanks, surf guys want the larger tanks so they can stay out or get to there spot befor they run out of fuel.

If you are building a all around sport boat i believe a b-pipe is best. a dry pipe can make better power if set up correct..With water injection . sometimes there are fitting issues with the dry pipes they are big and bulky and cause vibration issues/ cracking ect if not set up right.

You seem to be leaning towards team X-scream I think this could be a good choise. There (Tems) full carbon hulls and engine combo seem to work flawless

I would as peeps have said buy a complete ski package in the end it always seems to work better.. more ride time.. though you seem limited on ride time due to where you live.

Good luck.. have fun and stay safe...

I already have my own business bud. And I already own 2 skis, one is lightly modified and the other one has extensive work done to it. I really don't see what the problem is to some of you guys is at the amount I am spending on my ski. I never asked how much I should spend on one did I? Either way i appreciate your mother like concern. I think it is quite funny at how much negative flack I am getting regarding the price. WHO CARES and whats it to you. Any other input you have man would be awesome. I am a big boy, work hard for my money and own some nice expensive toys that I really enjoy playing with. Now I am going to build a bad ass ski to add to my collection.

chris, nobody is hampering what you're saying. i'm all for you building a big badass ski. but what i'm saying is these things depreciate extremely quick! you can do whatever you want with your money...that was just my .02 cents

when your ski far exceeds your skills, it will hurt your riding.

did you see some of the guys riding fully blown skis at daytona? they could barely stand in the surf, yet had skis worth 4x mines worth. some people have much more money to spend on stuff. if chris wants to spend 35k on a ski....its great for the industry because it'll keep these companies building stuff for the everyday rider like you and I a chance to stay in business and improve our riding.

i certainly have no problem with him spending his cash. i was simply trying to give him some friendly advice to try to help him to help himself, both financially and time wise. some people get ticked if they dont get the advice that they 'want' to hear. :dunno:

im done.

I can't speak for others, but I taylor my advise based on the person asking for it. Some of the questions/comments that may be naive, insulting or intrusive but it ultimately helps us decide what the best advice to give is. We're not exatly hammering you, just trying to get a feel for you, some of us just have better tact than others. :biggrin:

LOL really?! To me it makes perfect sence.


Its the guys that know what they are talkin about who spend 5-10k on their skis.


I mean really, How many Lambo owners do you think actually change their own oil? Or much less even know how?

exactly what I was thinking... if the dude is rich why would he even care to know how to do it... he's just asking questions, leave the guy alone..

Any way you decide to go - stay with one builder. If he would recomend something - do it, becouse he will know better. Complete package will work better, becouse it's supposed to. If you'll get big motor but pump and impeller don't match to it - you will spent lot a time and money try to fix it and , at the end , will have to do as your builder advice anyway.
Most of us ( I mean me ) have limited resourses ( money ) and try to bend some corners to get best of what we have available.
Buy a ski and build a ski - two different things. You buy one - it's your ski . You build one - it's part of you. But some things better leave for profesinoals. If you sure you can put whole package together right way - go ahad. You got doubs - let it be done by somebody ,who know his shiot.

Lol, I think you guys are thinking I am mechanically ignorant. All i asked was the difference between 62x, 62t. And was a little uncertain of epoxied cases. I appreicate the input regarding wet vs dry pipe. That I had no idea what the differences were besides the obvious.

As for which pipe I choose, I will see what pat wants to set me up with once I decide which engine package run.

Thanks for the input.

well with everyones input, once it is built I would like to make it to daytona with the ski next year. Would be nice to ride with other watercraft other than boats and converse with ppl who actually know what they are talking about.
 
62T - side draft cases - intake manifold is bolted on at about a 45degree angle. (96 +)

61X - down draft cases - Intake is bolted on parallel to the cylinder. (90-95 650's and 701's)

61X cylinders are they way to go for bottom end because of the port timing.
As far as cases, its a toss up. 61X are easier to remove the manifold whil in the ski and provides great bottom end because the fuel flows straight down (down draft) but they are hard on the reeds. 62T are the newer style and have good porting but are more expensive usually.
