dont quote me on these numbers but i believe the 03 turbo is 10 vane the 04 turbo is 12 vane and the 05-07 turbo is 14 vane the more vanes the quieter the turbo whine is straight piped the 03 turbo sounds like a jet plane taking off almost lol :icon_ford:
03 is 10 Blade, 04 is 12 blade, and 05+ is 15 blade. I put one on my 06 this weekend and yes the whistle is great, it has a tiny bit more lag off the line, but IMO pushes more ar quicker so when it hits it is alot quicker. I also build boost faster at a roll... Did I mention the whistle?? lol
