***Due to current market conditions and a large discrepancy in raw materials for finished components, we can not guarantee your product may not be out of stock. Although we try to stock many items in our multiple warehouse and use multiple distribution channels, this is sometimes unavoidable. If you are in a rush for a product, we suggest you text, email, message, or call us for availability. We will provide an ETA (based on vendor provided info) if an item is not currently available.
Staged injection allows the use of primary and secondary injectors of different sizes. The primary injectors are always used, and may be stock or other injectors with a rapid opening time and good spray pattern., The secondary injectors activate based on driving conditions, and may be larger than the primary injectors. The injector sizes and dead times for each set of injectors do not need to be the same. eg stock 310cc injectors can be used until boost, at which point both 310cc and 1300cc injectors are used.
It also is possible to use two independent fuel systems for each set of injectors. eg the secondary injectors may use E85 or race gas.
