Iv come to find out that its hard to say what is a problem and whats not.....I have over 100,000 miles on my car with No spun bearings....and its been raced in all types of conditons including LAs Vegas weather.......One thing is for sure it does smooth out the RPMs above 4k.
And im almost 90% sure it saves a lot fo people from spun bearings (only 90% because 10% of the people i tlak to, including myself have had no Spun bearing issue and have no DMD, but there cars are 1999 and up like mine is...hummmm...intresting.....
FletchaAutoSports will tell you he never need it. And he is running Underdrive pullies. If i had to make an guess, id say 98 and earlier use the DMD, oil pan combo. On 1999 and above im not so sure you need it.....its a great peace of mind though and im seriously considering it.
