    Great Clutch Options for 1992-2014 Vipers.

    Flywheels are steel with an aluminum option (SFI). The Gen 4-5 clutch is modular with the friction plate built in, you use your stock flywheel but the clutch plate does contact it.

    Put my 2009 ACR on the dyno.

    Thats whats advertised but it seems most car cars go into fuel shut off about 100rpm short of that. Really great numbers.

    New Viper Owner introducing myself

    The 97 cars were great, strong motor, the lumpy cam, forged pistons and super for upgrades. The Viper kept getting more refined with each year, that gave each model it's personality. I had a 1996 GTS Vin #141, tell us about yours?

    Great Clutch Options for 1992-2014 Vipers.

    I have learned a lot over the last 20 years working with Viper clutches and have developed some really nice clutch options with McLeod Racing in the past few years. We now have dual disc clutches for all generations of Viper's 1992-2104. These are not racing clutches, so they don't have the...

    Racelogic Traction Control

    Hey Bob, Have you ever had any issues with the traction control related to a weak or low battery? Has the system ever failed or needed parts replaced? I had some issues and wondered if it was isolated or not. Mark Jorgenson was helpful when we had an issue.

    Put my 2009 ACR on the dyno.

    Great numbers, you mentioned a 6400rpm rev limit, are you sure your car does not have a Mopar Performance engine controller? Happy Holiday

    New ACR Owner, need advice

    This is a common issue, the front fascia, hood supports and headlights often become misaligned from hitting a speed bump or steep driveway. It can be a little frustrating as you may need to remove the front bumper cover. The alignment measurements (starting with the radiator support) are...

    1996 GTS automatic belt tensioner pulley failure

    If you pull up and down on the belt you will be able to feel if the tensioner is binding. I always just replace the complete tensioner assembly whenever I have an issue.

    2006 Coupe Blk/Blk possible odometer fraud

    I have had nightmares with Carfax. A few years back we made a mistake entering a customer's mileage on a repair order, 24,000 miles when actual was 2400 miles. Little did we know our contracted invoice software company shared our information with Carfax, it took over a year to correct, our...

    1996 GTS automatic belt tensioner pulley failure

    Its not a common failure, but the tensioner and belt should be replaced every 30k if you run your hard. You should replace the whole tensioner as sometimes they stick and cause excessive belt tension, loading that plastic pulley more. Your car is going on 18 years old, depending on your mileage...

    Ralph wants/needs an automatic

    I think the dual clutch auto would be the only way to go. An automatic with a torque converter would make it less of a sports car, take away some power and would be less modification friendly.

    Heads/Cam or Paxton?

    Both NA and SC packages can work really well with the right combination of parts. With an NA package, anything over 580rwhp will require a camshaft profile that will sacrifice the low speed driveability. I have found that camshafts with good low speed cylinder pressure, the right gear and proper...

    Supercharging a GEN 4.

    Dan, I will see if Cory can chime in here. No I have never seen a car they supercharged. He had the kit at VOI a few years back, I saw pictures of the installation and dyno sheets. At that time he was doing them in house but wanted to supply a kit. He was not going to get an emissions...

    3.55 gears ?

    The 3.54 has always been the best all around gear. Many gear ratios are discontinued but we have tried 2.73, 3.21,3.33, 3.45, 3.54,3.73, 3.91, 4.10 and 4.56. Back in the day when we could not get better 5th and 6th gear ratios we would use the 2.73 gears for the top speed cars. When the 3.33 was...

    Supercharging a GEN 4.

    Cory at Snake Oyl products has a SC kit for the Gen 4 cars. Internal engine modifications are required as the engine is very knock sensitive, it requires forged pistons and modifications to the intake manifold for proper airflow to the rear cylinders. He worked with Motorola on the engine...

    Polyurethane Bushings Advice

    I have not had any luck with Poly/Delron bushings in Viper control arms. The arm will move in the bushing causing alignment change. Stock replacement bushings or changing to a race type monoball setup has been my solution.

    2008 Viper Acceleration - "like pullling an old man out of his chair" . . .
