Frequently Asked Questions About the C6 ZR1 ID1750-XDS Injectors
What common horsepower levels does the ID1750-XDS support on an E85-converted Cobalt SS?
With the necessary supporting modifications, the ID1750-XDS injectors are large enough to fuel a supercharged LSJ engine to over 450 horsepower (whp) when running E85. This gives ample fuel for major pulley and cam upgrades.
How does the ID1750-XDS handle the high fuel pressure required by the Cobalt SS's forced induction system?
The ID1750-XDS is designed for high-pressure systems, handling a maximum differential fuel pressure of up to 7.0 Bar (101.5 psi). This durability ensures reliable fuel delivery under the high boost conditions of the Cobalt SS supercharger.
What is the benefit of the high impedance rating of the ID1750-XDS for the LSJ engine's ECU?
The ID1750-XDS is a high-impedance injector, which means it's electrically compatible with the factory LSJ Engine Control Unit (ECU). This avoids the need for external resistor boxes or complex driver modifications typically required for low-impedance injectors.
Does the precise flow matching of the ID1750-XDS improve supercharger belt life on the Cobalt SS?
Yes, by ensuring excellent cylinder-to-cylinder fuel balance, the engine runs smoother with less internal vibration. This consistency can indirectly lead to a smoother running supercharger system, potentially extending the life of components like the belt and coupler.
Is the ID1750-XDS a good choice if I only plan to run pump gasoline in my Supercharged Cobalt SS?
For gasoline-only applications, the ID1750-XDS is excessively large and may complicate low pulse width tuning, leading to a rich idle. The ID1300-XDS is generally recommended for high-power gasoline-only builds for better drivability.
