Induction Solutions SledgeHammer System

If you are looking for the best four bar (2 nitrous/2 fuel) nitrous plate system in the business, this is IT!!

The Induction Solutions SledgeHammer nitrous plate system is based on a NOS plate.  Some of what makes the I-S SledgeHammer nitrous plate system different from an out of the box kit are the ways we blueprint, modify, flow and re-jet map the system, as well as the great tech support we provide.


A flow tool is a necessity to properly tune your nitrous system. Having your fuel pressure set accurately will provide the most out of your tune-up. If you purchase a Flow Tool with your system you will receive $50 off.

The Plate

The plate is 1” thick with stainless steel spray bars. One of the things making this plate unique are it’s four spray bars (2 nitrous/2 fuel) that equate to better flow, atomization, distribution and horsepower.

The Solenoids

The fuel solenoid is our own Bottom Exit Fuel Solenoid with a .184 orifice.  The nitrous solenoid is our Trash Can solenoid with a extra large .175 orifice for max flow it also has a PTFE plunger as well as a ~16-18 AMP coil. Both solenoids are equipped with filtered inlet fittings.

I-S Flowing

Each I-S SledgeHammer system is flowed and comes with custom jet mapping from 150-650 HP (600 on the 4150 plate). This kit includes all S.S. jets for each power level in 50 HP increments.
We can flow for E-85 applications, instead of gasoline, for a $50 upcharge.

The Induction Solutions Difference

There are many companies providing nitrous products to the market, however none offer the same tech support and quality of kits that we do at Induction Solutions. All of our systems are completely blueprinted with attention to detail and hand built to order. Each plate system is flowed for every tune up from top to bottom in 50hp increments and we provide a hand written tech sheet specific to every system, not some mass produced, one size fits all, print out. All of our AN lines come standard with a protective sleeving that acts as a conductive insulator and makes the line far less abrasive to painted and anodized surfaces than industry standard uncoated braided stainless lines. If you decide to purchase one of our complete kits, you will receive a truly complete kit that includes details like a purge kit and a race ready bottle including a gauge, NHRA racer safety, and bottle nut. All of the aforementioned parts are things most companies leave out and want to sell you separately, even though they are necessary to run the system properly and safely!

Complete Kit Includes:

* Plate, lines, filtered inlet fittings, solenoids with brackets to mount, I-S blue print, flowed, jet mapping,jets and tech support.
* 15LB bottle, mounting brackets, bottle nut (-6) and -6 supply line
* Electrical hardware including WOT switch, arming switch, power relay and connectors

Extras included in Complete Kit
A couple of extras we have included in this kit to make it a true complete kit are a -6 purge kit, racer safety on the bottle as well as a 1 ½” liquid filled nitrous pressure gauge on the bottle.

***Please note when you request a plate is built with hard lines you will lose some of the bigger tune-ups. *** You will also lose the bigger tune-ups on your plate when you are running E85, Alcohol or Q16. When using those fuels we also recommend that you have your plate flowed for race gas as well for an additional $75 at time of purchase.***
