It is very close to 15%.

Aftermarket it is possible to geet 15% from many vendors.
Helix13 sells 15, 17, and 19% and does custom sizes as well.
Some people have been testing down to 22% reduction pulley for the supercharger.

Yes I believe it is 14% and some change. The Hartge conversion uses a 17% and all the other tuner "kits" out there use the 15%.
The greatgro kit, however, uses a 19% and couldn't be happier.
