Help me choose some pipes for Viper

Thanks from what i have heard SLP's have been the ones to get so thats probably what i am leaning towards but won't be doing and thing right now because my sleds got some problems i think that it's the bearings but there is only one other person who had the same problem that my dealer has heard of but i will know more when i do some tests. but i hope its not to much of a fix but it will probably be a few hundred dollars that i don't have right now eeeeeekkkkk!! :o|
 

Kinger,
Do yourself a favor and stay away from pipes unless your willing to complete all the changes required. All Pipes require jetting, cluching, and additional tunnel cooler. If you want it to live you must do the head mod. Its an absolute must!!! Gonna cost $1350 minimum. --mac--
 
Allvipedup,

In my post I said that SLP's are the best, not CPR's.

I have come to this conclusion from personal experience with my SLP piped viper and the number of people on snowest who have vipers and how I have not heard of any burndowns with them. I am a mountain rider and wanted first hand experience from guys running these pipes in mountain conditions to base an opinion on.

From doing searches on this forum and not finding a single instance of a viper burning down while running SLP pipes. ALso with the SLP's you do not have to modify the head, just bolt them on, change the jets, reclutch, and enjoy (all this assuming you already have a rear heat exchanger like the viper Mtn).

Also there is a dyno graph of a viper pipe shootout where several sets of pipes were all run off the same viper on the same dyno and the SLP's had the highest horse power and the largest powerband,
top to bottom on a box stock Viper: SLP -- Bender -- Aaen -- Jaws -- Stock - http://www.snowest.com/fusetalk/attachments/Viper Pipes Dyno 1.jpg -

No I have not run other sets of pipes on my viper, but I did my research before hand and now do not have a need to run other pipes on my viper.
 
I have run Cpr's and know Aaen's. They are both good pipes, I think the Aaen's have a little more bottom end and produce a smidge more on top as well. I like my Aaen setup better. The Hauck kit works very well. For $900.00 you cant go wrong. Also the support is great. The fit is also very nice on these. I have spanked some big iron with this combo. By the way stock 600 ho's are no where to be seen. I look for bigger stuff for a challenge. Stock 800 also have not been a problem. My buddy has a zr 800 cross country that runs pretty good for an 800 and I beat him so bad he won't race me anymore. I have ran everthing under the sun and it takes something modified with a couple hundered more cc's to get out front. You can't go wrong with the Aaen's.
 
i have a brand new set for a viper in the box - bender - ive been thinking of getting rid of - call me if interested - 269 369 8629

Thanks for the advice, I don't usually skimp on things so I'm coming to grips with amount of stuff to make pipes work. What is the head mod? The opticool gasket from Bender?

Trying real hard to justify 1/3 of the value of the sled in mods and this is one of the best hp/$ mods for any sled, man I'm cheap! haha :ORC
 
In regards to best pipes, they all make a viper a different machine. But in saying that one set has to be better than most others. I chose cpr's because of the service and availability. I don't think you could go wrong with Aaen or SLP pipes either. Aaen has great bottom end, cpr's better top end and I haven't raced many SLP's but many on this site have had good results. SLP is a good company to deal with also. The head mod is probably only needed if you have a viper with more compression than most so I wouldn't waste my money. Aftermarket heads would be better than the head mod anyway. You better run a rear heat exchanger and make sure the coolant is always bled. But $1300 is way more than needed. Pick up a used set of pipes[400-500] and they probably would sell you a clutch kit or find one on this site, and put a rear exchanger on. Jets are cheap and the tuning is fun, but a egt is recommended for best results and reliability. $1000 max and you could have a very good setup.

ak ryda,

In your attached graph do you, or anyone else, know which pipes go with curves 1, 2, and 3? Additionally, was there an article that went along with the graph, and if so, how can I get a copy? Thanks in advance.
 
Wow this is nice, thank you! Here are some questions though based on less then 3000ft and 0 degree riding.


Rear Heat Exchanger: $100 (new) - Where is the best place to buy?
SRX Base Gasket: $25 - What is this for?
Main Jets: $15 - I'm thinking of 162.5 on all three?
Pilot Jets: $15 - 47.5 per SLP reccomendations
Nozzles: $45 - No idea what size

Total: $955 and most of the parts you could find used instead of brand new and get for cheaper.

8DN 20 weights: $60
Rollers: $55
Primary Spring: $15
Secondary Spring: $15
Helix: $75

I do have a fix power sports clutch kit which includes billet helix, springs, etc but I can't get them to give me the specs :o|
What could I possiblly have to change to make it work everything or could I use part of it? Thanks guys! :rocks: :yam:
 
Higest horsepower on the graph is benders, just below is the slps. Thats why benders blow up at 8000 rpm cause they build great cylinder pressure down low. I'm not biased cause I have CPR's. My CPR's have a cracking issue, Ive' welded them 3 times now, I'll leave it at that. (see pic)

Wow! That would suck. :o|
 
NYviper,

The graph came off this web site http://www.m-performance.com/Sidor/dyno_yamaha.htm but the link to the comparrison is not working for me for some reason. The top curve (in terms of horsepower, not the number next to the curve) is SLP, second curve is bender, third is Aeen, forth is jaws, bottom is stock.

Vipertripplexxx,

In rank in power from the top (not the number next to the curve) the list is SLP, Bender, Aeen, Jaws, and stock. These are real horsepower claims off the same motor from the same dyno, not claimed manufacturer numbers. That stinks about your pipes, bet that will ruin your day.

Is there any thing wrong with your pipes or have you just decided to go for a diff. feel with your viper? and i already have the rear heat exchanger so the only other thing that i need is the head gasket?
 
The SLP's are my preferred setup and I have done probably around 20 sleds with them, but have done about 6 different sleds with Bender's as well with no problems.
 
Cool and what kind of gas milage can i expect and will i need any thing eles or just the pipes besides the rear heat exchanger? ;)!
 
I'll put my 2 cents in for the Benders since that is what my sled's running and I am very pleased with them. I mentioned in another post that the dealer who built my sled has done at least 25 Vipers with Benders and has only lost one. They had a pair burn down in Canada at the same time, one stock and one with the pipes. They attributed this to bad fuel since both went at the same time.

Mine has 3800 miles on with no problems. It does have the rear cooler, opticool gasket and V-Force reeds, but the head has NOT been altered. I'm about 600' above see level and have run it from about 5'F to 40'F+. This one is jetted to Benders specs with the airbox and venting modified likewise (165's on two cylinders, 162.5 on the other, with 50 or 52 pilots. I'm working off memory here, so I'm not 100% positive on the jetting) Might be on the richer side compared to many, but it runs great for my taste and has held together. I'm running the Bender clutching (no freaking clue on the specs here!) and she spins right around 8500-8600 with approx. 4500-4600 engagement. 10-11 MPG seems to be about average for mine. Probably better lake racer setups out there, but this thing was built for trail and works great for my riding. Hauls butt as long as there is traction! ;)!
