hey all!

have been trying all winter to find a cherrie low mile SRX for my garage...but no luck...

So i have deceided to take my mint 02 Viper with little over 2000km, and power it up to SRX specs...was going to bender pipe it but herd nothing good...

Heres my parts list i need to find...

can you guys verify and add anything that i will need?

- 00 to 02 SRX 700 pipes (are the earlier 98-99 different?)
- Bender SRX silencer or hauck growlers
- custom manifold to adapt viper exhaust flanges to SRX (anyone have any specs or pics?)
- turks clutching
- SRX jetting
- SRX Water Rail
- 01 SRX 700 CDI
- SRX heads cut .20 thou to get rid of the o-ring groove and opticool gasket
- SRX base gasket

is there anything i am missing? would i gain much from porting the stock viper cylinders and srx heads?

will V force 3 reeds and spacers help?

how about a roller secondary clutch?

thanks guys, i am trying to put off buying a 4 stroke...hate the handling...but also hate getting passed...

will a SRX powered up viper keep up with a Attack 136 on the lake?

Thanks for all the help guys!

if anyone has any links or pics of the install of these parts i would be greatly appreated...especially the pipe install!
 
ok, a couple things....

-'99-'02 srx pipes should be the same. it was only the '98 year where the pipes had different ends.....no adjustable clamp for spring tabs.

-bender or hauck silencers will loose top hp and mph.

-custom manifold can be a pita for some to make.

-srx heads DO NOT have o-ring grooves in them. its the cylinder decks that do.

-you don't port 2-stroke heads, only cylinders.

-v-force 3 reeds/spacers won't do much on a stock bore and near stock rpm running srx or viper.

here is what i would do if i was in your shoes......get some SLP pipes, stock '00-'02 srx heads, mega power water rail (if you can find one), if you can't find one, you'll have to modify a srx water rail, get your cylinders ported (i can do this for you), and some good clutching. SLP pipes make great hp and are very trail friendly and fit very well. much easier to fit versus SRX pipes in a viper and the SLP's might even be lighter. you will need to get the srx heads shaved, however much the thickness of the head gasket is. if you flat cut alot off the heads, you may have to re-cut the step cut in the head and squish band angle. you can keep the stock viper cdi box as it works, but will get a few mpg less than if ran w/the srx cdi. i don't know how important fuel economy is to you. if you want to change reeds, some carbon tech petals on the stock cages works great on trail sleds. you can even drill out the airbox lid and shelf/divider in the airbox for some more airflow. the srx base gasket is a great thing to do. you could also run 1 layer of the opti-cool head gasket from hauck, and then just cut .010" off the srx heads. i personally run a hi-tech er roller secondary on my SLP piped viper and have GREAT results. very consistent.
 
thanks alot mopar!

you may have swayed my decisionion the pipes...i really dont have time to fab everthing up...would much rather a bolt on and go...but if the srx pipes are so much better it may be worth it...can anyone chime in on this!

how do the bender pipes stack up vs the slp's? can get the benders locally with jetting and clutching for $350

what will i have to modify on the srx water-rail to make it work on the viper?

how much should i mill from the srx heads...i hear 0.30

what about doubling up the srx base gaskets and cutting the head even more to raise the transfers?

and thanks for the tips on the reed and airbox!
 
you do not need an opticool gasket when you change the heads and the base gasket.

Either version of pipe will work if your using srx pipes. Both have advantages/disadvantages when it comes to fitment.

anyone who can tig weld can make a water rail from two stock srx rails but you can use the stock head, just have it machined. 22-23cc works good if your cutting the squish band to 17deg. 23-24 if your going to leave it stock.

yes, porting will make it better, call don pizor for porting and head work. He can recut the heads, pistons and cylinders to make the sled work a little better than stock.
slp pipes will work but will give you crappy mileage and not be as consistant as srx pipes. Power will be similar.
If you want to save yourself some work, buy a set of srx cylinders and heads, drop them on your motor. This will take care of your exhaust manifold issues and then you just have to do some fitting on the pipes.
 
if you are using the viper jugs with srx head, do not forget to add the dowels to hold the head still.

i thought aeens for a viper ran same rpms as stock srx? do not know how the power is but if staying with viper cdi, might be easyer to tune.
 
cant help much but i am doing a setup like this over the summer but i am going with the bender pipes for the reason that they are the only ones i know of that are designed for stock rpm range. i have also heard alot of horror stories but i have always done good with benders stuff. good luck

also keep in mind that stock viper porting is alot more aggressive than stock srx
 
srx pipes run at 8500 as well livewire...

i would like the idea of ported srx cylinders but its gonna add alot of cost and my engine is like new with 2000km...

i may just go with srx heads and bender or slp pipes....seems it would be easiest and i dont want to butcher this mint sled!
 
my thoughts also, most who use srx pipes end up modifying the hood and or bellypan by the shock mounts. true the srx ran them rpms also, any of those tripples ran that area, prime for most stock is at 8350 and that is where most aftermarket clutch kits put you if the rest of the sled is stock. i was also thinking that since the viper cylinders are ported more that it may be about like having srx jugs with a mild port job (not sure exactly how much diffrence between the 2 but have been told it is alot) thought that i would start with jetting like a ported srx and go from there since i am probably using the srx cdi i have, i have heard that you have more of a problem tuning with the viper cdi and use alot of fuel with the viper cdi. so far ive been told that using the srx cdi will not hinder much and will make the sled alot more reliable and not use much fuel either. hear of heating issues from the aggressive cylinder porting, and the very advanced timing of the viper cdi. thats why people use the srx head design and rear cooler like the srx had stock. another thing i will point out that doesnt seem to be noticed and may not mean much but the stock srx coolant rails under the running boards are a little thicker than any of the vipers i have had.

For what it will cost you to have your cylinders ported and heads done there is a set of ported srx cylinders and shaved srx cylinders in the classifieds for what it will cost you to have yours done.

SLP's on the dyno pull a few more hp than the benders, and IMO fit better and sound better. the SLP's will make your viper stout. trust me.....i have them. check out avatar. also, as far as how much to shave off the heads, depends on a few things......how thick of head gasket you are using, what fuel you want to run, etc. don't really want to raise the transfers more, by adding base gaskets, as it just reduces blow down time and the stock transfers are fine enough, especially w/a efficient set of pipes.

aaens on a viper peak at 9200rpm. you try and run a viper w/aaens at 8500, it will be doggy. them pipes like all of 9000.

i have had zero issues tuning in a piped viper. they can be reliable if setup right. i use an opti-cool head gasket and srx base gasket, along w/srx rear heat exchanger and safe jetting.
 
thanks for all the help guys, and i want to keep my porting stock, and machine the srx heads for 91 pump gas with triple pipes to run safe...

so guess i will have to look for a set of slp's first...and bender second!
and add a 01 SRX cdi

if you really want to try the srx pipe route, i have a set of '98 pipes and manifolds for sale.
 
i dont think i can hack up this sled mopar...it still had the protective plastic on the cylinder head when i bought it...lol
 
if your going to add 2001 srx cdi would you want to run pipes such as benders because of the fact that they are suppose to run around 8700 rpms which is 200 rpms above the stock srx peak rpm. so u dont really get out of its timing range?

you only lose like 1deg of timing if using the srx cdi on a viper, when running 8900.

i would rather you not cut the sled up either and find some SLP's that drop in and go.
 
might have found a set of slp's in the classifieds....now to get the heads and clutching and jetting in order
 
SRX piped vipers are the six million dollar man of the snowmobile industry, better, stronger, faster
