Nitrous Oxide is a product that has been used for decades in\nthe racing industry. It\u2019s simple, effective and relatively cheap for the\namount of power you get for your money.<\/p>\n\n\n\n

The simple rundown of “nitrous” is injecting nitrous Oxide\ninto your motor, which increases horsepower. There is more than one way to skin a cat, of course, so there are lots of\nkits, brands, products and systems out there for adding nitrous to your car.\nSystems range from very simple and basic without many components, to crazy\ncomplex. For our V8 HEMI\u00ae<\/sup> motors, most nitrous kits require injecting nitrous\nand additional fuel into your motor. This is done via a bottle of the good\nstuff mounted in the vehicle, generally the trunk, and a switch or controller\nthat opens and closes solenoids that feed the nitrous and fuel to your motor. <\/p>\n\n\n\n

Recently, Nitrous Express, a very well-known and established\ncompany that produces nitrous kits for a large variety of autos, came out with\na really slick and new approach for adding nitrous to the 6.2L supercharged\nHEMI motor. We are talking SRT\u00ae<\/sup> Hellcats, SRT Demons, Trackhawks and SRT Redeyes here. Most systems utilize a plate\nsystem that injects the fuel and nitrous at the throttle body. Some of the more\ncomplex systems use extension plumbing to inject the nitrous at each port on the\nintake manifold. Some kits have everything hidden, making it hard to tell at\nquick glance that the car has been outfitted with any sort of nitrous setup. <\/p>\n\n\n\n

When I saw this new product from Nitrous Express, I had to\ngive a round of applause to them for stepping outside of the box in putting\ntogether a product tailored so specifically to our platform. Enter the Nitrous Express Billet Supercharger\nLid!<\/p>\n\n\n\n

If you read my article about installing a supercharger pulley on your SRT Hellcat<\/a>, you would have seen how the factory supercharger comes apart. The top most part of the supercharger, called the supercharger lid, comes off with just a handful of bolts after removing the wiper cowl from the car. <\/p>\n\n\n\n

\"vehicle<\/figure>\n\n\n\n

The supercharger lid is the same size\/shape\/dimension on all\nthe 6.2L supercharged motors. What Nitrous Express did was machine a completely\ncustom lid for the supercharger that integrates nitrous all in one\npackage\/piece. And boy is it a beauty. <\/p>\n\n\n\n

\"vehicle<\/figure><\/div>\n\n\n\n

The company claims that now the product will produce more\npower both on and off nitrous than any other kit that leaves the factory\nsupercharger lid in place. So I just had to test this out. Because, you know,\nwho likes to leave stuff alone? What really stands out about this kit is where\nthe nitrous and fuel is fed into the motor. Instead of being sprayed at the\nthrottle body in front of the supercharger, it feed the fuels directly over the\nsupercharger rotors, which I totally love. <\/p>\n\n\n\n

I already had nitrous installed on my Dodge Challenger SRT Demon\nusing a plate kit like I mentioned above. So it was the perfect opportunity to\ncompare, back to back, how well this new system works. <\/p>\n\n\n\n

Install of a lid is super simple. The rest of the kit can be\na little more complex depending on exactly what options you chose to run with\nyour nitrous kit. You can keep it simple and basic, or stack on a ton of\naccessories and safety features. If you\nare using a more complex progressive controller that allows you to program how\nyour nitrous works (compared to just on and off Fast n Furious style), or\nadding bottle heaters, purge kits or bottle openers, wiring can get a little\nextensive. However, installing this beautiful chunk of aluminum is a breeze. <\/p>\n\n\n\n

The first thing you need to do is remove the wiper cowl from the car, which I went over in detail in the \u201cPulley\u201d How-To<\/a>.  <\/p>\n\n\n\n

\"vehicle<\/figure>\n\n\n\n

Next, you need to remove the Torx bolts holding the lid on to the supercharger, vac hose retainer and remove the MAP sensor on the lid. <\/p>\n\n\n\n

\"vehicle<\/figure>\n\n\n\n

After removing all those, you are now able to remove the lid\nfrom the supercharger. It might be stuck on there pretty good; be careful not\nto tear the lid gasket when removing the lid. <\/p>\n\n\n\n

\"vehicle<\/figure>\n\n\n\n

Make sure you don\u2019t lose the 3 small O-rings in the center\nof the supercharger. Your lid is now removed and there are a few parts we need\nto transfer over to the new lid. <\/p>\n\n\n\n

Remove the factory bypass valve via the four Torx bolts and\ngasket and mount it to the new billet lid. <\/p>\n\n\n\n

\"vehicle<\/figure>\n\n\n\n

Now we need to remove the blue rubber gaskets off the\nfactory lid and attach them to the new lid in the machined slots. In addition,\nattach the MAP sensor that we removed from the factory lid and mount it on the\nnew lid. <\/p>\n\n\n\n

\"vehicle<\/figure>\n\n\n\n

We are now ready to install the lid back on to the car. Just\ngo in reverse! Make sure the O-rings in the center are in place, check that the blue\ngaskets and the lid gasket are all where they need to be, set the lid down,\nand hand thread in the Torx bolts to make sure all thread in easily and the lid\nalignment is good. <\/p>\n\n\n\n

Follow the factory instructions below to properly bolt down\nthe new lid. <\/p>\n\n\n\n

\"vehicle<\/figure>\n\n\n\n
\"vehicle<\/figure><\/div>\n\n\n\n

With the lid now on, your install from here may be different\ndepending on which electronics and accessories you chose. The driver-side rear\nof the lid is where the nitrous and fuel lines connect into the supercharger.\nThese hoses are run from the nitrous and fuel solenoids. I chose to mount mine\nunder the cowl so that they are not visible with the car assembled, and running\nthe hoses out from underneath the brace. You are free to mount yours wherever\nyou wish, but I prefer to have as short of line as possible between the solenoid\nand where the nitrous and fuel is injected. <\/p>\n\n\n\n

The kit as it comes is meant to utilize a fitting that goes\ninto the main fuel line disconnect between the fuel line and fuel rails. <\/p>\n\n\n\n

On 2018 and newer cars, the driver side fuel rail has a port\non it. I prefer to pull my fuel from this port with a custom hose instead of\nusing the supplied adapter at the fuel line disconnect. <\/p>\n\n\n\n

\"vehicle<\/figure>\n\n\n\n

Wire in your solenoids, switches, controller and\naccessories as indicated in their respective instructions. I\u2019m using a\nMaximizer 5 progressive controller, which is programmable to function based on a\nvariety of sensor inputs from the car, such as RPM, throttle position, MAP\nsensor readings and more.  <\/p>\n\n\n\n

Install your nitrous bottle in the trunk and fill that bad\nboy up with the good stuff we all love (nitrous). Run your main supply line up\nto the solenoid in the engine bay. <\/p>\n\n\n\n

Throw your cowl back on and button up the install and you\nare ready to go. Pick your jet sizes appropriately to your setup (how much fuel\nand nitrous will be sprayed into the motor) and have your tuner supply you with\na new tune to function with the new found glory of nitrous. <\/p>\n\n\n\n

So does it work? Well, we all know that yes, nitrous does add\npower effectively. But did this specific\nproduct back up the claims of adding more power than using another style kit on\nthe factory supercharger lid? Check it out:<\/p>\n\n\n\n

Before pulling the stock supercharger lid off, we strapped\nthe car down on the dyno and made some \u201cbefore\u201d runs to get some numbers. We\nmade a pass with the stock lid and no nitrous, and the stock lid with my\noriginal nitrous setup. <\/p>\n\n\n\n

Stock lid with no nitrous: 872 hp\/818 tq.<\/p>\n\n\n\n

Stock lid with nitrous: 1,055 hp\/998 tq.<\/p>\n\n\n\n

Those numbers are our baseline. We swapped the system over\nto the new billet lid, everything else exactly the same, so all variables were\nthe same before and after the new billet lid. We even used the same dyno, tune,\njets and as close to the same atmospheric conditions as we could get!<\/p>\n\n\n\n

After installing the Nitrous Express lid, our results were:<\/p>\n\n\n\n

New lid with no nitrous: 900 hp\/874 tq.<\/p>\n\n\n\n

New lid with nitrous: 1,063 hp\/1,048 tq.<\/p>\n\n\n\n

\"vehicle<\/figure>\n\n\n\n

Wow, that is instant results! That is a 28-horsepower\nincrease without nitrous just by changing the supercharger lid. With nitrous, the horsepower gain wasn\u2019t as\nsignificant, but it picked up 50 lb-ft of torque! With so many aftermarket\ncompanies out there and so many products to pick from, I have to say that this\none really delivered. If you are considering nitrous as a power adder, I can’t\nhelp but fill you guys in on the results from this specific kit. I won’t debate\nif nitrous is a good power-adder or not. Either you are a fan, or you are not.\nI’m a fan, as are tens of thousands of others. But I can tell you that this kit\nis very well thought out, produced and clean. I think it\u2019s a really great out-of-the-box approach for a product specific to our HEMI engine-powered cars. And who can argue\nthat something like that is a bad thing?<\/p>\n","protected":false},"excerpt":{"rendered":"
