WARNING: There are some very inexpensive velocity stacks on ebay, while some really search good most of the types we have witnessed are of a very bad high-quality. Challenges consist of failures from very poor components / design procedures, poor higher inlet transitions and “universal” measurements. On this final level Silvertop and Blacktop engines have distinctive opening diameters, This implies a part can have slotted holes mounting holes to go well with the two differing types nonetheless it can’t have two different inside diameters, the result currently being that there'll be described as a nastly stage still left around the here changeover that will damage the general performance.
