How to Install A Nitrous NOS Juice Powershot Plate System On V8 Engine 125 Horsepower

September 1, 2019


Voice-over: Brought to you by Jegs. Paul: Well, I’ll just admit that I’m a big
fan of nitrous oxide. I’ve had a system on pretty much every car I’ve owned over the
last ten years. And the reason is pretty simple. There’s no cheaper way to get a lot of bang
for your buck. But in reality, nitrous is one of the nicest things you can do to your
car engine if you’re going to add extra horsepower. Now, I like the kits from Nitrous Oxide Systems
because they give you everything you need. They’re very complete and well put together.
And this is a company that has basically become synonymous with nitrous oxide. It’s right
there in the name. We’re going to be installing this NOS Powershot
system on a 1972 Challenger, which has a 402 cubic inch stroker small block, backed by
a TorqueFlite automatic transmission. Now, the NOS Powershot system is the simplest
way to add up to 125 horsepower to any V6 or V8 engine that’s got a four-barrel carburetor.
There’s no jets to change. It’s just plug and play. This is really the easiest, safest
way to add nitrous to a classic muscle car. Now, a quality nitrous oxide system doesn’t
have to cost a lot of money. That’s another big advantage. It’s one of the least expensive
ways to add quite a bit of horsepower to your car. And we’re actually going to see what
our gains are here with before and after testing on the dyno. So let’s dive into it here and
take a look at what’s involved in actually putting the system on. It’s something that
you can accomplish in your driveway in, basically, an afternoon. Invite your buddies over, have
a good time. By that evening, you’re going to have some extra power for this trip. All right, our first two dyno tests, we ended
up with 295 horsepower to the rear wheels and 321 foot pounds of torque, then the second
pull, where we got 305 and 332. So, pretty good numbers, but we can do a lot better than
that once we get the system on and get it activated. Of course, the real proof of how
well the system works is once the car is back on the roller. So let’s get to it. The actual installation is really straightforward.
It’s pretty basic. You’ve got the process of putting the plate in between the intake
manifold and the carburetor. You’ve got the plumbing. And there’s two components
to that. We’re picking up fuel from just a regular 5 to 6 psi that a mechanical fuel
pump puts out and bringing the nitrous forward from the tank in the trunk. And then of course,
there’s the electrical wiring. And basically, you’ve got an arming switch, and you’ve got
a wide open throttle switch. Now, of course, NOS also offers tunable kits
that have interchangeable jets, so you can control the power level. But for this system,
it’s really just about as simple as it can get. You don’t have to pull[SP] with any jets.
You don’t have to worry about whether you’re setting it up properly. That’s all taken care
of straight out of the box. Now, a lot of people are under the misconception
that nitrous oxide is a fuel. It’s not. It’s an oxidizer. It brings more oxygen to the
party. The science beh8ind it is not terribly complicated. But basically, what happens is
you’ve got this nitrous oxide molecule that, when it gets into the combustion chamber,
the heat that’s left over from the previous combustion cycle causes it to break apart
into two nitrogen atoms and one oxygen atom. And the energy required to do that actually
buffers the combustion a little bit. People say, “Oh, oh, why don’t you just feed pure
oxygen in there? Well, that would be an uncontrolled burn. The nitrous oxide makes for a much smoother
combustion event. And you’re bringing that extra oxygen, and you’re also bringing along
fuel. And that’s why you’ve got two solenoids on this system. You’re supplying that extra
fuel, and that’s what makes the horsepower. Now, one thing you have to consider with nitrous
oxide is that it does raise cylinder pressure. And that can mean that sometimes you need
to back off the timing a little bit. A good rule of thumb is backing it off one degree
of base timing for every 50 horsepower that you’re adding with nitrous oxide. Again, you
can read the plugs and take a good look at what your timing is doing, make sure that
you’re in safe zone. But with this kit, you follow the instructions, you’re not going
to have a problem. All right, so our installation is done. We’ve
done our dyno testing. How did we do? Pretty good, actually. We got 381 horsepower on our
first pull, 386 on our second pull. But that’s not really the story here. If you take a look
at this dyno graph, you can see how much extra power this is added in area under the curve,
not just at peak horsepower. And that’s the beauty of nitrous oxide. As soon as that system
starts working, it’s adding those extra ponies. So you’re not just wringing the engine out
right at its RPM red line. You can actually feel that power all through red band. And
that translates into quicker [inaudible 00:04:49] at the track. Well, we didn’t spend a whole lot of time
installing this. We didn’t spend a whole lot of money buying it. So this is really the
best of all possible worlds. We’re getting that extra horsepower. We’re not putting a
lot of strain on the engine when the system isn’t in use. And when it is in use, we know
that this is a system that’s been engineered to be safe for our car. Really can’t go wrong
with this. Like I said, I put nitrous on a lot of different cars. There’s a reason for
that. You just can’t beat the bang for the buck. Voice-over: Brought to you by Jegs.

    I am I stalling one of these kits. I do have a few questions. I didn't see the use of solenoid brackets are they needed? Also I will be using braided hose to feed the solenoids. What size hose was used in the video?
