Ha... They shouldn't need ANY time! They have got more than twice the displacement plus power adders, not to mention they are American V8's. So that should have been good enough to begin with, right?.
Actually what it comes down to is too much content on the part of the V8 owners. I mean, hell who's going to beat an already potent V8 that has one or two serious power adders on it? When they should be taking advantage of the same technology the 4G63 guys are using with twice the cylinders. Can you imagine pumping 125HP out of each cylinder on a daily driven V8? Can you say 1000 streatable HP!?! Why aren't more than just the incredibly hard core gear heads doing it? I'm pushing 125HP per cylinder out of my DSM and that EVO would walk the dog on me like I was one of those Mustangs or Camaros!
That's why I have other projects. Eventually I will get the time and money to employ the technical advances of the 4G63 wizards on a well built V8.
