    Close-out panel fix

    It really is a struggle to drill out those rivets and unglue the panel. That panel is not structural. We use plastic rivets when re-install the panel.

    2008 question around performance mods

    I have been able to get these cars to pass the emissions monitors with the stock controller. The upstream O2 sensors need to be relocated to collector, a CA approved or secondary production catalyst used and the downstream sensors mounted behind the catalyst with proper shielding.

    98 GTS Fuel Pump

    Hi David, Most likely your fuel pressure regulator check valve is bad, but considering the age of the car you might want to rebuild the entire module. I can source the parts if needed.

    Hood Gaps

    The gaps were all over the place from the factory. You can improve on that, but it requires a lot of adjustments and removing the front bump cover to align the radiator support.

    Removing Cats on 2000 ACR

    Removing the catalyst is bad for the environment. For racing use we remove them, but a new calibration is needed to make the car perform at peak performance. With the loss of backpressure a new fuel and timing curve is added. The downstream Cataylst monitor is removed as well.

    850 HP on a Single Viper Fuel Pump - Installation Outline

    Another note on fuel injectors. The side feed Gen 1 and 2 injectors are notorious for clogging up over time. I started by sending them out for ultrasonic cleaning, new screens, o-rings and matching when we rebuilt an engine, but when I found the before and after cleaning flow documentation...

    850 HP on a Single Viper Fuel Pump - Installation Outline

    Jack and Dan, Thanks for putting all this information together. In the past 25 years I've had to repair more botched fuel systems than I can remember. I think many shops just don't understand how to build a proper fuel system for the Viper. Many systems out there work, but are a compromise. The...

    Borla catback

    That system was developed for the Gen 3 car which had a rear crossover. On the Gen 4 cars its actually a little more restrictive than the stock system but does not seem to hurt power. It has a deeper tone but is not loud at all. You need to keep an eye on the rear hangers, they sometimes crack.

    Viper Climate Control Fan stopped working at any speed, Resistor and Fan good.Need advice.

    Typically it is the blower resistor or the blower motor. Its sounds more like the blower motor to me. The motor gets water in it and rusts. When that happens it works at times, until it freezes up.

    Bump Steering Kit

    You will need to shim the steering rack. You need to remove the shocks, unload all the control arm bushings, then check the toe change from drop to bump. Shim up the steering rack on each side for the least amount of toe change. For a 1 inch drop start with a 1/4 inch shim on each rack mount.
