This injection pump was developed by Industrial Injection. We were the first to develope this product. This pump is the closest you will find on the market to a NEW VP44 pump. We select all of the most agressive parts Bosch makes for maximum fuel delivery increases and
timing advancement. This pump wil develope an additional 80-100hp depending on the injectors you are running. This pump has been copied by others but ours is still the bench mark and the best value on the market. Because of all of the new parts that goes into a Hot Rod VP44
the price is a bit higher than our stock pumps but they are well worth the price.
