need help with bender triples

srx run with oring....viper with gasket ... u will need to make those cylinder machine for oring if u wanna used them
 
yes, you will need to either machine the srx heads for orings, or the cylinder tops for orings. i have the ability to do that for you, but just don't really have the time now.
 
if i am shaving the heads cant a run a stock head gasket or a opticool gasket there will be no groves in the heads or cylender couldnt u run a viper gasket?
 
yes, you can run just the stock viper gasket w/the srx heads. no need for a opti-cool head gasket, as the srx heads take care of the equal cooling problem. i said you could either machine the cylinder tops for orings or the head, because then there wouldn't be any shaving or recutting the squish or dome needed. you could just bolt on the srx head and go. you can shave the srx heads, but you will need to shave the heads however thick the head gasket is and then recut the squish to get back the proper clearance.
 
when u say cut for the squish what do u mean and what is the normal thikness for the head gasket mopar do u have a piped viper.
 
i sure do have a piped viper. squish is the clearance from the piston crown, to the angluar flat (will lead to the "dome" of the head), around the edge of the head. i got .030" for a stock used head gasket thickness. you can have the squish clearance anywhere from .055"-.065". the squish clearance must be measured w/the engine in its assembled state. tighter squish and higher squish band ratios, will yield higher msv's. you need me to machine those heads for you....lol.

no i have a milling machien in the shop along with a lathe and all the other stuff my uncle is a machinest. but i would like to know what kinda pipes u are running and what u are running for jets and how meany miles u have on ur motor with pipes and what the best setup is for around here. thnaks for all the info i have a bet going with the boys at the shop that it wont blow up or melt down and evryone is beting against me if i blow it up i have to pay they 150$ each so i realy want to set it up for trail riding and able to tune a mach zero. my friend is telling me that is going ot eat me on the lake he sold his 99 srx for the mach zero and i want to show him that its a peace so i can shut him up. any tips i have the srx heads off a 02 srx and they fit great and i made up a coolent rail out of aluminium.
 
where exactly are you located? i have aaen pipes. i'm was running for mains 150-mag and 147.5pto/center. but i have my carbs vented to atmosphere, instead of the airbox. i left the needle stock and pilots stock, but turned the fuel screws out to 2-3/4 turns. i have 1300 miles on my viper since the pipes. i can help make it reliable for you. what year mach junk does your buddy have?
 
im not to sure 06 i think and i am located in northern ontario about 2 houers from sualt saint marie in espanola ontario. i dont know the elivation is around here i think around 3000 ft. and i have 162.5 meg and center and 167.5 pto and i dont like that set up way to bad on gas id like to run smaller ones and how do u vent them out to the atmosphere. and i ride about 4500 milles a season. will it still be reliable i have 21000 km on it or 12500 miles on it some thing like that. any help would be nice. thanks mopar
 
hey guys did some testing today in teh snow it runs great the plugs are all cardborad brown. i need new reeds for my sled the stokers are chiped and broken what is the best bet. and for pyromiters what is the best bang for ur buck i am runing it with stock head and stock head gasket and an srx base gasket and i ran it down the road for wide open and mid rang for about 10 to 15 miles and it didnt seem to get hot. on the speedo it read 136mph after it cam down from 146mph or so.
 
if your running the stock head and you have your viper piped, you need to have the mag cylinder jettted fatter than the pto or center. the mag cylinder gets the hottest, w/the mag side of the center cylinder getting hotter than the pto side of the center cylinder, and the pto side the coolest. on piped vipers, running the stock head or speedwerx head, i like to jet the mag cylinder 1 main jet size larger than the pto and the center cylinder 1/2 size larger than the pto. example.....152.5mag, 151.3 center, and 150 pto. that was an example, so don't try that jetting on your sled w/carbs vented to airbox. that'll = booooom. to vent carbs to the atmosphere, you simply unplug the hoses from the carbs, that run into the airbox, and just zip tie them to the other hoses on the carbs, but so the end of the hoses face down. with doing that, you will be closer to 152.5 main jets.
 
ok thanks mopar right now i have the vent thing un done from the air box and i am runing 162.5 mag and center and 167.5 pto so if i swap them out will that help me and what do u recomend for reeds and egt gauges and pyromiters.
 
for reeds, just get some carbon tech reed petals and bolt them to your stock cages. i would recommend you having the mag cylinder fatter than the pto and center. if the carbs aren't plugged into the airbox anymore, than there is no need to run main jets as large as 167.5 and such. what is your elevation again, riding temps, and all mods done to the sled? if all you have is bender pipes, then i would run like a 152.5 main on mag cylinder, and 151.3 on center and pto. set needle position to 3-1/2 (raising needle 1/2 clip postition from stock) try that and check the plug color. i would also suggest 47.5 pilots and 2-1/8 to 2-1/4 turns on fuel screws.
 
i have bender triples srx beas gasket im runing at about 1300 above sea levle my avrige temp is betwen -6c to -15c. i have the carbs dicotected form the ari box i have the ari box drild out to benders specs and the jet are MAG & CANTER 162.5 and PTO 167.5 and 47.5 pilots or 45 pilots i cant realy remeber. and the fuel air screw is at 1 7/8 turn and the neddel levle is at the stock seting. thanks for all the help mopar do u have any pics on how to do the car venting and geting at the needle. thanks u have been a big help in my project.
 
i just got ahold of some bender install instructions and see that they want the pto cylinder at 167.5 and mag/center cylinders at 162.5. and pilots at 55. and needles stock. i'm not sure why they have the pto jetted fatter. i've always seen the mag cylinder get the hottest on stock headed piped vipers. i guess, just try it like bender says, and see what ya get. check plugs and piston wash. leave the vent lines plugged in for now, and just run it like bender says.
 
i tryd your way i am runing 45 pilotts and i have a 162.5 pto and center and a 167.5 mag and the lies diconected from the air box and it seems to run beter down low midrang and wot and the plugs are looking beter and the mag piston isent geting as hot as it was befor i just did the temp buy feel but i am going to do it with a leaser temp gun i have. what kind of egt gauges would u recomend for my set up
 
westach analog gages are cheap, but do work. i'd go w/the digatron unit. has memory, backlight for night use, programmable warning lights, etc. what did you do w/the needles? could you do a wot run and pull the plugs? then take pics of the plugs and post them here.

yes i will try and do that i need to do in on the weekend buy the time i get home frome work it is darck. i left the needles at there stock seting for now. and thnaks again for all the help
 
Bender machined head?

I bought a bender modified head off a clearance part bench at a dealer a few days ago for dirt cheap. What do they change when they machine the head? What kind of gain do you get? And does it mean I can run the same jets all the way accross? :dunno:

The guys at the dealership don't have much expierience with tripples and couldn't tell me much.
