Induction Solutions Holey Moley Plate System

If you are looking for the best single entry class restricted plate on the market, this is IT!!

What makes the Induction Solutions Holey Moley nitrous plate system different from an out of the box kit is the ways we blueprint, modify, assemble, flow and jet map the system, as well as, the great tech support we provide too.


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 1.305″ thick, black anodized, billet aluminum, CNC machined plate. One of the things that make this plate unique is it’s four hole inlet for enhanced carburetor signal that equates to better flow, atomization, distribution and horsepower even when the system is not activated. The 4500 plate supports up to a 2.200″ throttle blade (a 2.500″ available upon request at an additional cost) and the 4150 will support up to a 1.750″ throttle blade. This plate has no o-ring seals or epoxy to break down or fail over time making it extremely durable!

The Solenoids
The Trash Can nitrous solenoid with it’s .177 orifice provides the plate with a solid flow of nitrous even in the biggest tunes, helping keep the nitrous in its liquid state for the densest charge possible. The nitrous solenoid has a PTFE plunger as well as a low amp coil, only drawing ~16-18A making it a very durable and responsive piece. The Bottom Exit fuel solenoid has a .178 orifice that increases initial flow creating a quicker feed rate while progressing, reducing the initial lean spike seen on many similar systems while progressing. Both solenoids are equipped with -6AN filtered inlet fittings and mounted on a black anodized solenoid bracket mounting both solenoids on the passenger side to provide as much clearance as possible for most combinations.

I-S Flowing
Each I-S Holey Moley nitrous plate system is flowed and comes with custom jet mapping from 150-600+ HP. This kit includes all brass widebody jets for each power level in 50 HP increments.  We can also flow for E-85 applications, as well as alcohol and methanol combinations though they may require an upgraded fuel solenoid for the additional fuel required.

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 covered in fire sleeving, filtered inlet fittings, solenoids with brackets to mount, I-S blueprint, 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.***
