what are you missing in terms of power? You looking to make over 1200whp? You can already see how well the 307xRs T25s are doing with the VG30DETT. Unless you want to go beyond this which there isn't much market for this and there would be no point. Besides sooner or later you know who will be copying. Then you'll have copy cat manifolds in no time, time after time. Killing the balls off the innovator.
