Thank you for your response. Some of the posters do not use the spec oil for the car per owners manual. Another factor in my decision is that my Viper is not stock. Mark J. did the mods and Mark L. is familiar with the mods. This board has alot of data but it is of limited use in real time situations. For example, last Fall I was at Homestead Speedway and I needed an answer to a question. I called Mark J on my cell and got the answer. I then called Mark L on my cell phone and set up an appointment to implement the suggestion of Mark J. No stories; no waiting; no excuses. And that is the way it always is. The stories about Vipers being ******* at a tuner's shop for weeks or months are easy to find in the archives. ( Admittedly this can also happen with some dealers.) Those who want to indulge in the belief that it takes that long to do the mods described in those posts are free to do so but that does not mean they are correct. My first round of mods in 2006( supercharger, competition coupe oil pan, cat back exhaust, Motons, Eibachs, lowered and corner balanced, and a few minor things) was done within one week after Mark J. received the car from CAAP. The second round of mods done in January 2008 ( Racelogic traction control, installation of 08 differential driveshaft and transmission, mount PS2 tires, install Woodhouse engine and transmission mounts, install prototype MGW shifting mechanism, and a few other minor things was done in one week. Then, last November, to improve track performance, after making an appointment and while I waited for the car, I had Mark L's tech install the 172 degree thermostat, the colder set of plugs and the DC blower tune. A good performance team is a very valuable asset and I feel that I have been very fortunate to have one.
For those who do all their own wrenching and mods, that's great. I prefer the comfort provided to me by me knowing that Mark J and Mark L, on a combined basis, probably know more about the mechanics of the Viper and its maintainence than anyone else except for The Wizard ( Chuck Tator) who I hold in equally high regard.
