Frequently Asked Questions:
No. A 500% over set is strictly for competition builds with extensive fuel supply, turbo/airflow, tuning, and engine hardware upgrades. Street use is not recommended.
Do I need dual CP3s or a stroker pump?Yes—at this flow level you will overwhelm a stock CP3. Use a high-output CP3 or dual CP3s plus an upgraded lift pump and big-line kit to maintain rail pressure under load. See our CP3 pumps and fuel system components.
Are these SAC or VCO nozzles?SAC nozzles, honed with S&S’s proprietary process and matched for consistency.
What tuning is required?Competition-calibrated tuning is mandatory. Timing, pilot, pulse width, and rail control must be set for high-flow injectors to avoid damage.
Will stock engine hardware survive?Not recommended. Add head studs, improved cooling, and robust air system components to manage cylinder pressure and heat.
Is there a core charge?Core policies vary by configuration. Some sets require a core return; see cart for any applicable charge and instructions.
