How does the InstaBOOST system eliminate turbo lag?

The InstaBOOST system injects a controlled amount of nitrous oxide to rapidly spin your turbocharger. This brings the turbo up to speed much faster than exhaust gases alone, significantly reducing or eliminating the delay before boost builds.

What is the purpose of the adjustable pressure switch?

The adjustable 1-8 psi pressure switch allows you to precisely control the nitrous activation. You can set it to engage at a specific boost level, ensuring the nitrous helps spool the turbo without overpowering your setup during the initial launch.

Is this system street legal?

This Nitrous Express InstaBOOST system is not CARB approved and cannot be shipped to California. It is intended for off-road use only. Always check your local regulations regarding nitrous oxide systems.

About this part

Product Details

If you're running a big turbo on your drag car and dealing with that frustrating turbo lag, the Nitrous Express InstaBOOST system is designed to get you off the line faster. This kit works by delivering a shot of nitrous to spool your turbo quickly, then smoothly ramps out the nitrous flow so your turbo can take over and make its power. The result is a significant boost in acceleration without the delay you'd normally get from a large turbocharger.

This system features a well-built composite bottle and an adjustable 1-8 psi pressure switch. You can tune the pressure switch to control when and how aggressively the nitrous engages, helping you dial in the perfect launch for your setup. It’s a straightforward way to get more responsive power from your forced induction system, especially when you're pushing the limits with a large turbo.

This kit is intended for off-road use and is not CARB approved, meaning it cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and safety guidelines.
