I-S SledgeHammer System

QUICKEST AND FASTEST PLATE IN ULTRA STREET!! (FIRST IN THE 4’S)

SledgeHammer New

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

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

The Plate
The plate is 1” thick with stainless steel spray bars. One of the things that make 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 our own Bottom Exit Fuel Solenoid with a .185 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 nitrous plate system is flowed and comes with custom jet mapping from 150-600+ HP(550+ on the 4150 plate). This kit includes all S.S jets for each power level in 50 HP increments.  We can also flow for E-85 applications as well.

Kit Includes: plate, lines, filtered inlet fittings, solenoids mounted to laser cut solenoid bracket, I-S blue print, flowed, jet mapping and jets. Comes ready to put on manifold and hook up supply lines.

PPH numbers are available upon request at time of placing order for no additional charge!

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

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.


Choosing the Stainless Hard Line option will reduce the maximum horsepower capabilities.
