    Car shuts off for no apparent reason?

    Mine did that. It was the fuel pump going bad. Could also be your fuses or relay. Start by checking those. My pump would intermittently cut out. it was a pain trying to prove it was bad so I could get it fixed under warranty.

    Math formula for HP estimation

    That result assumes constant torque (at the wheels) throughout the run.

    Anyone have a Radiator hose blow off on them while tracking?

    You might want to check your coolant recovery tank cap to see if its opening up at 16 psi (or whatever they're supposed to release at). If the pressure got too high it could push a hose off. Mine starting leaking at the top hose because of this.

    check engine light

    Yes, it will throw a code, it's only an emissions problem so it won't interfere with driving the car. An OBD II reader can reset it but I think I read somewhere that if you replace the cap and go through six or so cold starts the code will reset itself...not sure about that.

    What's with the picture of Santa Claus holding the silver frisbee? Are those spinners in his fog light openings?

    My snake seems to be purging anti-freeze... (?)

    Cut the spring down to about an inch long and then the anode won't get caught up inside the tank and hold the relief valve open.

    Are you using the Roe anode cap? That can cause this problem.

    FACTORY REP FROM DODGE SAYS ALL VIPERS RUN HOT! HE SAYS 260 DEGREES IS OK!

    Re: FACTORY REP FROM DODGE SAYS ALL VIPERS RUN HOT! HE SAYS 260 DEGREES IS It might not be all that bad. Could be they dropped a nut or bolt into a water passage when it was rebuilt and they can get it out. From your previous posts it seems this all started after the Arrow rebuild. How could...

    Overtemp, with a difference?

    The heavy gauge wire running from the Roe relay that's tapped into the harness is the +12V line to the fan. Apply 12V to that. If the fan goes on then it's your stock fan relay and either the Roe relay or the Roe switch that's bad. If not, it probably has to be the fan motor.

    Overtemp, with a difference?

    The Roe fan controller has it's own relay and circuit. If it isn't working then either its relay or the snap-thermostat switch isn't working.

    Hyperactive coolant overflow?

    I had the same problem with the Roe cap. The anode was getting caught up in a ridge inside the coolant tank and it was pulling on the relief valve and holding it open all of the time. As soon as the coolant started to expand it would just flow out of the cap into the front bottle. Shorten the...

    VIPER OVERHEATS! ANYONE ELSE HAVE OVERHEATING PROBLEMS? HOW TO FIX?

    Re: VIPER OVERHEATS! ANYONE ELSE HAVE OVERHEATING PROBLEMS? HOW TO FIX? If everything outside of the block has been checked it's probably something inside. Blocked or restricted water passage?

    2001 RT RUNNING VERY HOT!! ANY RECOMENDATIONS?

    If it weren't for the fact that you said it ran fine for a while after the rebuild, but then went back to running hot, I would guess that you have a restricted passage(s) in the block. Maybe there's some way a tech. can check for flow resistance, similar to flow benching heads?

    Viper Technical Information

    Good question. I don't have my manuals with me right now but I think there is another book which covers diagnostics. That has some information you can glean off of it. It's just a series of flowcharts for testing things...checking voltages, pressures, etc. (It may be in the shop manual, can't...

    No, they don't really give you a lot of that kind of info.

    What doe you guys/ gals think of this Wideband O2 kit? Looks nice!

    I assume the sensor can't be used instead of the stock O2's..or is there a way to connect this to the engine computer? Will the unit read two sensors so that you could look at both banks?

    Plug wire info needed!!!!!!

    Even at 1 amp of current (way more than the coil produces) your voltage drop difference between the two types of wires is about 100 volts. I'm not exactly sure of the numbers but your coils are putting out voltages of at least 10,000 V or more. You would have to have wires with resistances on...

    Plug wire info needed!!!!!!

    Not really (unless your resistance is huge). The coils are putting out big voltages at low currents so the voltage drop across the wires is pretty insignificant.

    Car will not start..

    The manual for my '99 shows that the only relay in the circuit is the fuel pump relay in the trunk. I don't know why the relay is shutting off after a few seconds. Pull the relay and short out the pins, you now have a direct circuit (except for the fuse)to the pump. Then check the power at the...

    Car will not start..

    If you have a shop manual you can look up the relay pins which actually switch the power to the pump. Pull the relay and short those two pins, if the pump starts up then you know that either the relay is bad or your alarm circuit is disabling the relay, otherwise it's the pump or the wiring to...
