Diesel is also usually used in these vehicles because of the initial power and fuel needed to accelerate these vehicles. Page 1 of ... nitrox is a mixture. Adding a turbo will only add to the build-up of heat inside the combustion chambers. Nitrous bottle weight is a critical variable. One important aspect of piston selection depends on whether it’s destined for a street/strip engine that will spend most of its life running naturally-aspirated, or if it’s slated for a race build that will see nitrous oxide applied more or less all the time. There's nothing new about boosting an engine for more horsepower and torque; turbochargers and superchargers actually date back to the turn of the 20th century. We suggest a hardened nitrous series ring, carbon steel nitride ring, or a stainless steel ring for best longevity.”, While the tendency in recent years for both racing and factory engines has been to run tighter end gaps for better efficiency, special care must be taken for nitrous powerplants. Right off the bat, you may think that a nitrous oxide application and naturally aspirated application are identical. If you have a large displacement drag car that operates on staged nitrous oxide induction, you might not want to add a turbo because it won’t make much of a difference. No matter how much the three kids have accomplished over the past year, the conversation always turns to how Blower is a bit of a parasite, and Turbo keeps putting too much pressure on everyone. There are limits to how fast you can operate them. A turbo compression wheel does not create maximum boost until the throttle is in a WOT (wide open throttle) position for a number of seconds. This video is unavailable. Upping strength of the internal components was a no-brainer since the crank, rods, and pistons must be up to the task of withstanding the extra power production offered by nitrous or boost… “While we have off-the-shelf pistons that are designed for nitrous, there are many customers who are going above and beyond what we call standard. Once you choose a primary control strategy the rest become offsets to that strategy! Overall, the trade off between low piston weight and having a sufficient ‘heat sink’ favors the latter factor in a nitrous application. If you want to fill your own the easy way a supply bottle and some line 10-20lb bottle + line $150 if you shop around. (2 Min Cooldown)Nitro boosts share a cooldown with potions. A 10 lb bottle of Nitrous is good for about 3 minutes of boost (7-10 ¼ miles runs) but shouldn't really be operated for more than 10-15 seconds at a time if you don’t want to blow up your engine. they're just cool, but if you just wanna go real fast, stick with nitrous and spend the money One place where you see the turbo versus non-turbo debate is at the local drag strip or race track. Terminator X and Terminator X Max. Winner of the Global Press Award at the 2007 SEMA Trade Show, e-Boost2 allows the user to control, monitor, map and compensate boost. The AMS-2000 offers numerous control strategies you can choose from. Reasons for boost have already been stated multiple times. So which one is better? In addition to the tops, there’s no reason to miss out on the performance benefits of a coated skirt on a nitrous application either. ENGINE TECH, This may be the perfect solution for them, but it is not something a big displacement engine owner considers when they want to increase the power and performance, as well as transfer of that power to the streets through the wheels. For the most part, that’s true, but there are a couple key differences which must be taken into account. While nitrous has the reputation of being hungry for pistons, we’ve learned that by specifying the right parts that are designed for the unique thermal and physical stresses spray imposes, it’s not impossible to put together a durable, powerful, nitrous combination. Turbos are great if the vehicle is able to suitably control the power of the wheels, drive shaft, tyres and the engine. Nitrous you cannot crank the boost up and spray on pump gas. A properly filled bottle will retain roughly 50 percent of area for the gas above the same level of liquid nitrous. So instant throttle response is not one of the advantages of a turbocharger. Nitrous boosts a car’s performance by increasing the amount of oxygen molecules in the combustion chamber. The biggest difference is that a full racer nitrous boost will last twice as along as a cop's boost, but has less power per second than the cop boost. This makes a compression height of 1.000” and simply does not give enough room for the ring lands to live.”. Turbo: 6: Aug 17, 2013: good nitrous tuner in NJ/NY area? Bf 109G-2, Wings of Dream Museum in São Carlos, Brazil. The 302 long block featured a cast crank, rods and pistons, all stuffed inside a late-model, 2-bolt block. This generates air pressures that boost a motor’s horsepower potential. Racers have used it for better performance since the early hot-rod days in the 1950s. This graph shows both the boost pressure and back-pressure curves generated by both the standard intercooled turbo motor, and then after the introduction of the NX unit. Though every engine can be turbocharged, that doesn’t mean some naturally aspirated car owners would want to add them to the power plant currently residing under the hood. For example, most nitrous companies using a 0.063-inch nitrous … Click here to add or remove balls from this comparison. Thus, creating a much bigger combustion to increase performance. Nitrous oxide's chemical formula is N2O, as it incorporates two nitrogen atoms with one oxygen atom. When the rings end up running into each other, they lock in the cylinder bore and start yanking the top land from the rest of the piston. Nitrous gets a bad rep not because of its inherent flaws, but because it’s such an ‘easy’ path to power - or at least it seems. Modern rings last a very long time, so it’s less of a factor with stainless and carbon steel nitride rings.”, Besides providing a compression seal, the top rings also play a critical role in transferring heat from the body of the piston to the cylinder wall, and with the added energy in a nitrous application, this becomes even more important. Aluminum can only go through so many heat cycles, as they lower its hardness level. Nitrous Vs Nitrox Discussion in 'Non-Diving Related Stuff' started by Packhorse, Jul 11, 2006. “While we have off-the-shelf pistons that are designed for nitrous, there are many customers who are going above and beyond what we call standard. And a 3 port regulator, set to 10PSI and connected to the inlet tract after the turbo. Hot Pursuit 2010 has, for Racers only, an extra type of Nitro Boost called "Turbo". Incorrect ring end gap is probably in the top five reasons why pistons fail.”, Another recent trend in piston design has been to move the oil ring down to the point where the groove actually intersects the pin bore. As you can see in the video, as the nitrous comes on, a visible puff of something come out from under the hood—this was the second kit blowing loose. The features of the AMS-2000 will make tuning, logging and adjusting to pick up ET and MPH easy and straight forward. Klugger and Coxwell had a decent staging dual at Lights Out 8 in a classic Nitrous vs Turbo showdown during Round 1 Eliminations. New turbo technology makes it so that every combustion engine with enough exhaust flow can benefit from the boost generated by a turbos’ compact and powerful fin turbine. your compression is probably too high (remember, boost=compression). Hot Pursuit 2010 has, for Racers only, an extra type of Nitro Boost called "Turbo". You may never WOT a throttle around town streets as a turbo would let the daily driver down when it comes to throttle response. Often, the larger and heavier cars use turbos to increase the power for forward momentum. They're totally different. Horsepower Vs. Boost Pressure by Richard Rowe . © Copyright 2016 A1 Wheels and Tyres | All Rights Reserved | Developed by Web2go, Nitrous Vs Turbo: When Turbo Should Not Be Used. I love blowers! In modern performance systems, nitrous oxide is stored remotely in a high-pressure cylinder that feeds electronic solenoids metering flow to the engine. While due to a lazy jerk off my nitrous line leaked 1/2 bottle of nitrous into the useless atmosphere i'm not currently running the n.o.s. Nitrous Express. “The further the top ring is moved down, the more it is protected,” DiBlasi explains. For e.g., You need 1 BAR boost, (15PSI) plus say 10PSI working pressure plus 10 percent at least. DiBlasi says yes; “We have great success using oil rail supports to allow the pin to go into the oil ring. It’s a metal-based auto catalytic plating that has the precision to accurately cover features as small as gas ports without impeding their function, and it will actually help prevent carbon fouling of the piston top, which eliminates a potential source of detonation, regardless of what kind of engine it’s being used in. A combination of power and traction is required to control an engine’s potential and transfer it to the wheels. Graph 1: 302 Ford-NA vs ZEX Nitrous (75-HP) The rebuilt 5.0L long block was stone stock, including the camshaft, cylinder heads and cast internals in the short block. Nitrous oxide works incredibly well for short-duration events such as drag racing or sprints where heat buildup is not much of a concern. At elevated temperatures, nitrous oxide is a powerful oxidiser similar to molecular oxygen. Nitrous oxide boosts a car’s speed. But e-Boost2 is a lot more than just a boost controller – it can also control water spray, methanol or nitrous injection, manage shift/warning lights and read/monitor RPM. Nitrous is a compressed cryogenic gas. Providing the ring lands, crown thickness, and ring material is designed for the application, there should be no difference to the performance if using a rail support or not.”. These foreign made “rice burners” could never compete against some of the big displacement muscle car motors that you’ll find on the race tracks. People that use this to run more boost, blow their engines because its not reliable for that. Tech. Nitrous can also be applied to diesel engines a 130ps Golf TDI got almost double the power - but boy racers don’t buy diesels – well not until recently. But is it a good idea for a piston designed for nitrous duty? See how they did it. DiBlasi adds, “Skirt coatings also help with friction reduction and controlling piston-to-wall clearance.” It’s an inexpensive ‘premium’ feature that’s become common on shelf stock parts, not just custom slugs. “In the design process we will adjust the ring thicknesses, materials, and lands to match the loads required,” says DiBlasi. until i get a new line. Boost vs. speed boost controller Turbo 24 Feb 1, 2020 0 Fastest/quickest STOCK motor with boost? 1. There is no exact formula, as every application and duty cycle is different. Nitrous has a bad reputation for blowing up engines and is often even called "cheating." This cooling process helps to lower detonation and boost engine power output. More awesome! Boost builds with rpm more like a turbo, but throttle response is better because of the belt-drive setup. Expected Nitrous Output vs Actual Output. The difference with nitrous oxide is that there is no real ramping up of load, but rather a step change. Our back-to-basic test motor was nothing more than a stock rebuild. “This creates the least amount of unsupported area from the pin towers to the rod, limiting flexing.” Obviously, keeping the piston as cylindrical as possible helps the ring seal, as well as reducing friction and wear and promoting heat transfer from the piston to the cylinder wall. Most of the off-the-shelf parts are intended for naturally aspirated use, so we will have to convert them to a custom piston as it’s a unique situation. Per DiBlasi, “If the customer is requesting to put nitrous on a part that was never intended for nitrous, then we will hav… Per DiBlasi, “If the customer is requesting to put nitrous on a part that was never intended for nitrous, then we will have to custom make it. The performance key is the huge torque gain that comes from a given amount of nitrous added to the engine. Nitrous oxide doesn't have this sensitivity to air temperature because the nitrous The trick is not to depend on this for boost. Target lambda varies depending on how much nitrous oxide is to be used. Nitrous motors rely on atmospheric pressure to carry the nitrous into the motor. Now that you know the downside of turbo power, you can see why a big muscle car motor might do better with nitrous oxide and a monitoring system for heat. Also, if we have a shelf part designed for nitrous where the majority of the market uses a 200-300 shot, but someone wants to use 600 shot, then we will most likely move them to something custom. Turbos spin at extremely high speeds – up to 100,000 rpms or faster when they are making peak boost pressure. What do you like better? Nitrous vs. meth injection. Nitrous can also be applied to diesel engines a 130ps Golf TDI got almost double the power - but boy racers don’t buy diesels – well not until recently. At room temperature, it is a colourless non-flammable gas, with a slight metallic scent and taste. Heat is the number one power robbing component in the combustion engine. Two powertrain management systems from Holley that offer plug and play control for most small block Ford engines including Coyote engines starting at just $999. The number one defining difference between wet and dry nitrous system is whether or not fuel is introduced into the foggers. Nitrous, or Nitrous Oxide is a power adder that provides incredible "Bang for the Buck" but for a number of reasons that we'll explore today, almost never gets used, and that's a shame because there's really no better way to get a reasonable boost in power for peanuts. Nitrous oxide doesn't have this sensitivity to air temperature because the nitrous decomposes at combustion temperatures, which means by the time the spark goes off it doesn't matter anymore what the timing was. Nitrous Oxide Injection. This allows for shorter overall piston height, more room to put the ring package farther down from the crown, or a combination of the two. According to DiBlasi, “We have various ring materials that are popular. But to achieve such speeds, it takes more exhaust flow from the engine. 1/4 Mile 119 Jan 18, 2020 B Nlr boost compensate clutch question 1/4 Mile 15 Jul 12, 2019 max boost with water injection Turbo How To Avoid Common Causes of Blow-By and Oil Consumption, Proper Motorcycle Engine Break-In After Rebuild, Piston-To-Wall Clearance: Myths, Mysteries, and Misconceptions Explained, The 500 Horsepower Naturally Aspirated K24 Engine by 4Piston. Let's weight the cost on the high end of Nitrous VS a turbo or supercharger. Home / Articles / Nitrous Vs Turbo: When Turbo Should Not Be Used There is a big debate over the use of turbochargers in naturally aspirate motors, especially amongst drag racers. It is soluble in water. Instead of increasing the boost, Matt decided to see what the spray would gain him on his next run—this time with both kits turned on. As a result, spark and fuel needs are similar to an equivalent supercharged engine seeing instant full boost. Nitrous Dry Injection Vs Wet Injection Dry injection is when you inject the nitrous by itself – without any fuel mixed in it. Nitrous is compressed Nitrogen Oxide (N2O). Nitrous can also be applied to diesel engines a 130ps Golf TDI got almost double the power - but boy racers don’t buy diesels – well not until recently. “It all starts with completely understanding the customer’s needs,” DiBlasi continues. “The crown thickness and taper angle of the top land will also be configured for the specific application. It doesn't matter if you're at 2500rpm or 8000rpm, you'll still get gobs of torque with nitrous. Learn what it takes to create a piston optimized to survive and thrive on the bottle. Everything You Need to Know About Ring Gap! Nitrous: 20: Feb 28, 2014: Nitrous but only busas little sister: Nitrous: 4: Feb 1, 2014 : J: Anyone use a small nitrous shot to cool intake charge? Just like any other power adder (or even a highly-strung naturally aspirated engine), the secret lies in knowing the limits of the components you’re using, and upgrading where necessary to handle the extra stress. Large displacement motors and pickup trucks are susceptible to these environments more than any other engine. I'd take turbo boost over nitrous and i'll never use another small blower. The final power producer, and the one we chose to add first to our 5.0L, was nitrous oxide. The additional heat and higher cylinder pressure generated by nitrous applications also drive the shape of the piston in other ways, with DiBlasi noting, “Crown thickness, pin length, and pin thickness are all critical to nitrous engines.” The design of the crown must take into account how heat will transfer, especially in regions like the valve pockets where hard edges and thin spots can create potential detonation sources. Depending on many factors such as coil size, amperage, plunger weight, plunger lift, Nitrous pressure, etc. Wiseco’s proprietary ArmorPlating process, which protects the crown, ring grooves, and pin bores, actually becomes harder when exposed to heat. Remember that point. The problem with nitrous is maintaining bottle pressure. Drivers who have small displacement motors may choose to include a turbo to get the response they need on a race track when they push their RPM to the limit. The proper pin thickness and length are designed to handle the demands of the engine while making sure the pin bosses have enough pin engagement material.”, The location of the top ring becomes a compromise; while modern factory engine designs tend to place the primary compression ring as close to the crown as possible to reduce crevice volume in order to help emissions, this is less than ideal in a nitrous engine. Many of the racers have different experiences when it comes to boosting the parts installed. We include a guideline of instructions that walk our customers and engine builders through some math based on their bore, application, duty cycle, and a few other variables. Besides providing a compression seal, the top rings also play a critical role in transferring heat from the body of the piston to the cylinder wall, and with the added energy in a nitrous application, this becomes even more important. “This will help deflect the heat off the crown of the piston and give it longer life. What’s The Difference Between Wet vs Dry Nitrous? Winter is good for boost. One of them that comes to mind is putting a 4-inch stroke in a Small Block Chevy with a 6-inch rod. If you're already running more than about 8:1 CR. - http://www.teespring.com/stores/justa6Follow me - http://instagram.com/itsjusta6Want to support me even more? Nitrous Vs Nitrox Discussion in 'Non-Diving Related Stuff' started by Packhorse , Jul 11, 2006. boost by Smith nitrous harness: Nitrous: 13: May 19, 2014: How Much Should Nitrous Cost per LB???? Special high-altitude interceptors with GM-1 nitrous oxide injection high-altitude boost and pressurized cockpits were also produced. Steps. Copyright © Wiseco Piston Company Inc. All Rights Reserved. A 10 lb bottle of Nitrous is good for about 3 minutes of boost (7-10 ¼ miles runs) but shouldn't really be operated for more than 10-15 seconds at a time if you don’t want to blow up your engine.
