you listed the converter in your opening title as a PTC-B15-ss
just so everyone knows its not a PTC brand convert but the part # of it starts PTC- which is a little misleading to those that dont the difference..
but please dont refer to the converter or the company as PTC as you just did saying "PTCs website... " its confusing to those that hear that the PTC is the converter to get
PTC is not Pro-Torque, they are two seperate companies that make converters with PTC being the converter of choice for the High Hp guys looking to be at the top of their class , the company that made this converter is Protorque.com
the converter you posted and the link you posted helped to clarify it as a Pro-torque brand and its catalog number is PTC-B15-SS which is a restalled stock D5 12" listed as 2200-2800 and should be good for most turbos from stock up to a 60mm well into the 11s. i have had good results with it on a stock turbo getting one just into the 11s on that converter without even using the lockup.
