I know there has been a ton of posts reguarding the reliability of piped Vipers. But I don't recall anything specific to the 04's with DCS.

I'm thinking about piping my Viper S but I'm a little gun shy after burning down my 02' CPR piped Viper.

I've heard that the 04's use a better piston and with the addition of DCS I would assume the risk of a burndown is reduced.

I have also heard that with the DCS you have to have the head modified or the vibration from the pipes will trigger the DCS.

Anyone experienced any problems with their piped 04's?

I would really have my doubts that the vibration from the pipes would cause the DCS to trigger... Vibrations should be roughly the same I would think because it's not the pipes, it's you're engine and there should be no change in vibration... Although i'm saying this without knowing what DCS is lol. (Detonation control system maybe?) The only advice I can give you is to go a little bit richer than what is recommended and keep checking your plugs... if they're too dark, get it just right. You obviously know that the burn down was probably caused my engine running too lean.
Doesn't help a lot but gives you something to work with! lol
 
Yea...I tried the going rich on the mains with my 02'. In fact I was up 2 jet sizes from the CPR recommended jetting and the plugs were dark brown after a 1/2 mile run at WOT. It was great until I was on a long pull down a snow covered road on a 25 degree day. About 1 mile into it....it blew. I'm told that it could be related to having ceramic coated pipes....they run cooler under the hood so the air getting to the airbox is a little cooler, thus....leaner. Who knows, but $1000 in parts later I was a ready to give up the extra power for more reliability. But if what I've heard about the 04's having a more durable piston and the DCS as a safety net I would certainly consider pipes again....Ya, I really miss the extra juice under the hood.

Now I'M starting to second guess getting pipes for my sled... this isn't good lol. Although i have heard about one or two brands (i think just one) that has a real bad lean point in them, maybe you got em? There are plenty successful setups with pipes I guess you just need the right ones and go real conservative and start from there.
 
all i can say is you should do the head mod on all vipers with pipes to be safe, gas aint what it used to be, i ran a full season with cpr and no probs, but i do have the head mod, would not do it any other way
 
yes DCS will help because it detects detonation which defianately takes place on lean burn downs, but it is still not a 100% guarantee that it wont blow, just added safety margin.
 
I have seen 2 04 Viper S,s with SLP pipes grenade. Both in the mid range.

Please describe the headmod for CPR piped 03 Viper...... Cost?..

REVIVED! I am speculateing they were talking about the bender head mod. Evens out compression on the viper motors. This in with conjuction of moving needles and opticool head gasket promote engine longevity. Carbs will have to be changed as well, should have a differant main jet in PTO cylinder with lower compression. As far as price I would check with Bender.

Its $175 to have your head modded at bender. Just make sure when you get the head back that the compression is the same in all three.

I dont know if you guys get worse gas in the states or what. But I have 5000+ km on my viper with speedwerx tripples. Havent had a problem yet, and my motor has 20000 km on it. Just have a rear cooler from an srx. Have run regular gas in it this year (all the station had in the middle of nowhere) and still held it wide open for at least a minute straight 25x this year and no blow upsl

If the motors good and the jetting is good dont see how you will have a problem.
 
can say that i have the hauck pipes there head mod opticool head gasket rejetted carbs and needel adjustment and i havent had any issues with my sled. the one mode i havent heard anyone speak of is the vent tube from the carbs to the air box. in the instructions i recieved with my parts from hauck they tell you to remove the vent tub from the air box and vent it to the air under the hood and not to the air box that under the forced air induction it will force a lean condition and will cause issues under wot. something to consider as i have 4600 miles on mine with no issues running mid grade when prem isnt available fyi

This makes sense to me as I have read guys having pig rich issues when the vents get pulled out of air box, Not sure if they were already jetted pretty fat to begin with though.
