    2) "I'm curious if there are any 50-state smog legal headers for '08+ cars that SRT is aware of - or envisioned." We've not developed any for Mopar

    Art 138 asked: 1) "I recently had Belangers installed on my 09 ACR....the starter sits about an inch from one of the header pipes.....how vulnerable are the internals (of the starter) to the intense heat created by header pipe?" Don't have experience with any of the non-Mopar aftermarket parts...

    JonB - PartsRack asked: "Recent customers with the Gen 4 08-09 MoPar ECU are "delighted" with their results, especially on 08. Early customers of that PCM were 'satisfied' with the results, but the recent feedback is HOT! Is the Gen 4 PCM in a state of 'continuous improvement' kind of like a...

    The Very First Viper?

    We did a little more investigation today, asked a few more questions, and talked to some other old timers! The new version of the early history has been modified in the original post (see above) and corrects the timing of VM03 which was actually the first Viper development car (even though it...

    The Very First Viper?

    We'll try and set the record straight for you. Some day we need to write a book with the real story (we will help you Herb!)…here’s what we know and remember. Some minor details may be slightly off but this is pretty close. Hope this helps, enjoy! The very first Viper was the show car which was...

    Engine pops and bucks above 3000rpm

    We will assume you have no MIL lamp or codes? Agree with Mark, look for plugged catalysts. Let us know if you do have any codes, that may give a better indication.

    If the issue is only when the door is open and you go to close it, definitely check to make sure you have the latest BCM flash.

    That is likely due to the AIS servo getting sticky and loosing steps... Thats the bypass idle air servo motor. If the servo gets sticky it can loose steps, and over time looses track of it's position. A battery disconnect will force an AIS reset, if the car works normally after a reset, it is...

    Martin – Sure sounds like something is wrong with the odd bank. Now that you have replaced the bent pushrods have you had any that re-occured (in the same spot)?

    1) The stock wing position was determined through track testing with race ride heights and splitter extension installed. That configuration provides a balanced handling setup under most track conditions. We do not recommend changing from the stock wing position, because it has a dramatic...

    Bob, how’s the Jeep? 1- If your issue is the glass clicking against the roof when you open the door, it may simply be caused by opening the door too quickly (the glass needs time to drop). It can also be caused by pulling hard enough on the door release lever that it goes beyond the normal...

    We have not tested the Stoptech calipers. When switching calipers, you need to watch piston areas and displacement volumes to make sure the brakes are well balanced and that you don't run out of master cylinder volume. Proceed carefully.

    Yes the new paint shop will have a few process improvements. The appearance quality will be equal to or better than the previous paint work. We are still looking at the paint chip concern. It is definitiely a consideration in our process planning.

    The Viper spec tires have a "C1" on the sidewall.

    There is also heat soak which affects engine torque. If you are sitting with a hot engine idling, then jump on it, you'll get a gulp of hot air and even maybe some knock as a result that will need to be run though the engine. An aftermarket intake is even worse than the stock airbox.

    It sounds like this is a condition that has changed – it was not doing this initially, it started and is now getting worse. This would seem to indicate that something is going wrong. Are you the original owner? Can you be sure that it is indeed stock? Can you tell us which cylinders bent the...

    This is almost impossible to diagnose on a webchat. Data is your friend. If the tires break loose, the revs will rise more quickly. If they hook hard, it can feel like a bog compared to the tire spinning, but it will likely be faster. Are you sure it is not due to traction differences...

    Martin - If you are bending pushrods then you could very well have valves hitting pistons. The other possibility is that your valve springs are weak or are set too close to or at coil bind. Do you have stock heads, valves, springs, cam, piston drop? Have the heads been milled which will put the...

    I'll quote Herb when he just read this question, "Your ****ing RIGHT we're proud of it!" All the SRTs are our children. We all have tons of personal sacrifice in bringing them to life. We are definitely proud of them. They are not perfect, but they are all pretty awesome. Our experience...

    This is not easy to answer, for two reasons: 1) There are available options (wheels, radio, etc) for the models you listed that can affect weight. 2) Changes are sometimes introduced mid-model year. For example, the added grip of the ACR tires prompted us to use solid halfshafts. To...

    It depends on whether the downstream O2's are behaving, and whether the catalysts are functional. The factory PCM is only built to function properly against the factory catalyst loading and flow rates. Changes to the emissions system are likely to cause issues at test time. (And such...
