ok guys.. here's a list of flow rates and est. hp ratings that i've picked up from other posts and vendors' sites. I there's some conflicting info between trims and flow rates but this may be due to differing factors, one possiblilty being just wrong information gathered from other posts. But if anyone can add to / confirm / deny the following flow rates it would be much appreciated, I feel this list may be able to benefit a lot of us who are considering an expensive turbo upgrade in the future, if we can weed out any incorrect information or myths. Pay special attention to the posted BHP and WHP. They aren't the same as one is brake horsepower and the other is obviously wheel horsepower. Also notice which info is from a vendor and which is from a post. Don't take anything here as gospel.
