The Best true bolt on HPOP Upgrade
We recommend this pump for modified injectors. The warranty service and performance is top notch. The Adrenaline is the perfect high pressure oil solution for stock and upgraded injector setups. Injectors require a minimum of 2600 psi high pressure oil to fire correctly. High pressure oil is used to atomize fuel coming from the injector. The larger the injector and nozzle the more the pressure drops on a stock HPOP. 2800-3000 psi is the optimal operating pressure under wide open throttle for correct atomization of the fuel. As expected, stock injectors won't feel quite the "wow" that larger injectors will, but you will feel it and when towing you will wonder how you did without it. Larger injectors are the big winners with higher volume high pressure oil. The bigger the injector, the more power gains. Every injector size realizes fuel mileage. But make no mistake, this is not some small increase meant for small injectors.As common sense dictates, the larger the injectors the more power you realize from adding higher volume high pressure oil. This pump will deliver fuel economy, performance, and power to any vehicle. The Adrenaline HPOP upgrade will future proof your truck because it can supply a large range of fuel injectors. Diesel Site is now now backing the Adrenaline HPOP up with a 24 month unlimited warranty.
