Performance Additive Testing and High Output Diesel Fuel - MegaMejor

Video Performance Additive Testing and High Output Diesel Fuel

Irrespective of the game, fans will at all times search out a aggressive edge. In motorsports, even the slightest benefit can put you a step forward of the pack. So what do you do when you’ve maxed out your setup, aren’t occupied with working nitrous, but nonetheless need just a little one thing additional? One of many best methods to squeeze extra energy out of your components mixture is to pour a excessive efficiency gasoline or additive within the tank. However how do you select the fitting gasoline to run, or one of the best additive to combine in?

After selecting the minds of a number of profitable truck pullers and drag racers within the diesel business, we determined to check Scheid Diesel’s excessive output gasoline and Powermist Racing Gas’s Nitro-XD additive in two unbiased checks. Nevertheless, as a substitute of testing these merchandise on some mega-horsepower sled puller or a 10-second screamer, we ran them in a each day pushed, 550hp road truck. Whereas our positive aspects could not mirror the outcomes you can see on a excessive horsepower, all-out competitors utility, our check proves that each merchandise can improve horsepower on milder builds.

HIGH OUTPUT DIESEL

With dozens of aggressive truck pullers working Scheid Diesel’s excessive output diesel gasoline, it didn’t take a whole lot of looking out to determine which gasoline we needed to check. Within the Illinois Tractor Pulling Affiliation alone, almost each 3.0 Class competitor makes use of it. It’s marketed as a competition-ready, premium mix of off-road diesel.

Scheid’s excessive output diesel gasoline could be had in two 2½-gallon plastic jugs, though many aggressive sled pullers buy a 55-gallon drum of it. As a consequence of its chemical make-up, this specific model of Scheid gasoline is against the law in some truck and tractor pulling organizations (LIGHTNING10912). Nevertheless, Scheid additionally presents a gasoline that may be ran legally in most sanctioning our bodies (LIGHTNING10913).

POTENTIAL HORSEPOWER GAINS

Whereas the Scheid gasoline is alleged so as to add as much as 30 extra horsepower in excessive efficiency, mechanically injected diesel mills (engines we’re guessing are within the 1,500 to 2,500hp vary), we had been anxious to see if any positive aspects might be had on a road truck making roughly a 3rd of that energy. Nevertheless, and since it could not have been cost-effective to fill your complete tank filled with the excessive output gasoline, we bought two 2½-gallon jugs and carried out our testing completely on the chassis dyno.

DYNO TESTING

To measure rear-wheel horsepower, we strapped our check mule to a load-cell, SuperFlow chassis dyno owned by Randall’s Efficiency in Gladstone, Illinois. To remove as many variables as attainable, we ran every check the identical means: all pulls consisted of a 35% load being positioned on the truck, the runs beginning at 50 mph, ending at 80 mph, and being carried out with the truck’s four-speed computerized in Third gear (direct) and the torque converter locked.

PUMP DIESEL

Previous to including the excessive output gasoline to the tank, we made a number of dyno pulls on the pump diesel we arrived on. The best peak numbers achieved had been 533 hp and 915 lb-ft of torque. Enhance checked in at 43-44 psi throughout every check.

To test the Scheid fuel on the chassis dyno, we simply disconnected the 5/8-inch fuel line running from the truck’s tank to its lift pump and hooked an additional section of the same diameter hose onto it. This way, we knew we would be running pure Scheid fuel through the engine, not a diluted mixture. The fuel system continued to send its return fuel back to the tank (it enters through the top of the tank), and yes, the fuel disappeared quickly with nothing returning back to the test container. Still, we were able to make three solid, all-out dyno pulls with the 5 gallons of Scheid fuel on hand. Approximately half a gallon was left over after testing. The rest had made its way into the truck’s fuel tank via return. — To check the Scheid gasoline on the chassis dyno, we merely disconnected the 5/8-inch gasoline line working from the truck’s tank to its elevate pump and hooked a further part of the identical diameter hose onto it. This fashion, we knew we’d be working pure Scheid gasoline by means of the engine, not a diluted combination. The gasoline system continued to ship its return gasoline again to the tank (it enters by means of the highest of the tank), and sure, the gasoline disappeared rapidly with nothing returning again to the check container. Nonetheless, we had been capable of make three stable, all-out dyno pulls with the 5 gallons of Scheid gasoline readily available. Roughly half a gallon was left over after testing. The remainder had made its means into the truck’s gasoline tank through return.

+9 HP, 15 LB-FT

After a brief settle down interval, the truck was fired up and the excessive output gasoline was examined. Our first remark was that the truck was now producing 47 psi of enhance. After three constant dyno pulls, with horsepower rising every time, a most of 542 hp and 930 lb-ft was achieved. And, as you possibly can see from the overlaid dyno graph picture, the horsepower and torque positive aspects parallel the pump diesel curve beneath it. Horsepower doesn’t merely spike at 3,200 rpm—the positive aspects exist throughout your complete rpm vary.

NO TUNING CHANGES

Many fans imagine that altering tuning, be it mechanically or electronically relying in your utility, can yield far superior positive aspects when working Scheid’s excessive output gasoline. We don’t doubt this idea, however it ought to be famous right here that we made no tuning adjustments throughout testing. Our aim was to see if merely working a extra environment friendly gasoline by means of the engine would result in extra energy. It did.

Whereas some would possibly say a 9 hp and 15 lb-ft achieve is negligible, it may be the distinction between profitable and dropping. Discover how the horsepower and torque curves mirror one another. These positive aspects had been realized throughout your complete rpm vary, not for some transient second within the truck’s powerband.

NITRO-XD ADDITIVE

Whereas the Scheid identify carries with it prompt credibility, the gasoline additive we selected to check got here from a supply that was unfamiliar to us on the time. However after a number of profitable drag racers talked about an additive known as Nitro-XD, made by Powermist Racing Fuels, we determined to provide it a glance. One competitor specifically swore by the stuff and warranted us it could make a noticeable distinction.

Made by Powermist Racing Fuels of Newton, New Jersey, Nitro-XD is a diesel-specific, oxygenating fuel additive. The unique chemical compound uses a proprietary combination of ethers to carry more oxygen into each cylinder. It’s an additive most people won’t tell you they’re running—because it works. DW-1603-FUEL-06(insert photo and caption near this area of body text) For our testing purposes, we started with a 5% mixture of Nitro-XD, and then increased the ratio to 10%. Following our test, the makers of the additive told us that a lot of truck pullers run somewhere between a 20% to 25% mixture. For the most part, tractor pullers stick in the 15% to 20% range. — Made by Powermist Racing Fuels of Newton, New Jersey, Nitro-XD is a diesel-specific, oxygenating gasoline additive. The distinctive chemical compound makes use of a proprietary mixture of ethers to hold extra oxygen into every cylinder. It’s an additive most individuals gained’t inform you they’re working—as a result of it really works.DW-1603-FUEL-06(insert picture and caption close to this space of physique textual content)For our testing functions, we began with a 5% combination of Nitro-XD, after which elevated the ratio to 10%. Following our check, the makers of the additive instructed us that a whole lot of truck pullers run someplace between a 20% to 25% combination. For probably the most half, tractor pullers stick within the 15% to twenty% vary.

WHY IT ADDS POWER

For apparent proprietary causes, the oldsters at Powermist Racing Fuels didn’t reveal any particular substances inside the Nitro-XD formulation. Nevertheless, they did inform us the important thing to why its additive works so properly: a novel mixture of oxygenating ethers (opposite to some beliefs within the diesel business, there isn’t a nitromethane in Nitro-XD). This successfully makes the additive an oxygen extender, which is to say it carries extra air into the cylinders. Whereas the added oxygen is sufficient to improve horsepower by itself (what our check outcomes present), including extra gasoline together with it will probably improve horsepower even additional.

MORE TORQUE

Along with making extra peak horsepower, Nitro-XD permits most engines to start producing torque at a barely decrease rpm than an engine working solely on diesel gasoline. This may occasionally clarify the rise in 60-foot occasions we skilled in our drag strip testing. In accordance with Rick Fales, proprietor of Powermist Racing Fuels, the additive rearranges the torque curve and also you come up by means of the decrease engine speeds faster. “Principally, it adjustments the speed of acceleration in actual time,” Fales instructed us.

DRAGSTRIP TESTING

As a substitute of testing the Nitro-XD on the chassis dyno, we took our check truck to the native eighth-mile dragstrip. We bought began by making two passes on pump gasoline. From there, one quart of Nitro-XD was added (5% combination) and two extra passes had been made. Then, we poured one other quart of Nitro-XD into the tank (roughly a ten% combination) and made two closing passes. In an try and remove as many variables as attainable, we tried to launch the truck the identical means on every go. Locked in 4-Excessive, we shallow staged the truck, constructed 9 psi of enhance, and left on the final illuminated amber of a Sportsman tree.

For our testing functions, we began with a 5% combination of Nitro-XD, after which elevated the ratio to 10%. Following our check, the makers of the additive instructed us that a whole lot of truck pullers run someplace between a 20% to 25% combination. For probably the most half, tractor pullers stick within the 15% to twenty% vary.

QUICKER AND QUICKER

After making back-to-back 8.24-second eighth-mile runs on pump diesel, we felt our launching methodology was constant sufficient to start testing the Nitro-XD. Though no actual seat of the pants change was felt, the primary quart of Nitro-XD knocked 0.06-seconds off of our eighth-mile elapsed time. Then, a second quart yielded the identical consequence: one other 0.06-seconds faster than that. And, judging by our half-tenth improve in 60-foot occasions between the 5% and 10% mixtures (1.83 seconds vs. 1.78 seconds), it helps legitimize the speculation that Nitro-XD offers extra low-end torque.

After backing up the 8.12-second run, we had been satisfied the additive had one thing to do with shaving 0.12 seconds off of our unique time(s). However that isn’t the entire story. Additional proof that we had been making extra horsepower on Nitro-XD got here when the truck started to run sooner entice speeds, on a constant foundation. Whereas 0.42 extra mph won’t appear to be a lot, in a 7,000-pound truck, that interprets into an 8-to-10hp achieve on the wheels. By our calculations, the ten% combination of Nitro-XD added between 8 hp (primarily based on the mph improve) and 24 hp (primarily based on the 0.12-second drop in E.T.).

Here you can see evidence that the Nitro-XD made the truck a tick faster through the eighth-mile. Note the difference in 60-foot times between the second and third timeslips (1.83 seconds on the middle slip vs. 1.78 on the right). On the 8.18-second pass (one quart of Nitro-XD) the reaction time was quicker than on the 8.12-second pass (two quarts of Nitro-XD). This leads us to believe that the second quart (bringing our mixture to 10%) might’ve added more horsepower, and especially some extra low-end grunt to get us off the line quicker. Each time we added more Nitro-XD to the tank, the truck went 0.06-seconds faster. We thought about trying a third quart after the 8.12-second pass, but the track was on the verge of closing and we didn’t want to hot-lap the truck. For the sake of speculation, and because we have evidence that the Nitro-XD dropped our E.T.’s by 0.06-seconds each time we added a quart, a 15% mixture could’ve potentially gained us another half a tenth or more. — Right here you possibly can see proof that the Nitro-XD made the truck a tick sooner by means of the eighth-mile. Observe the distinction in 60-foot occasions between the second and third timeslips (1.83 seconds on the center slip vs. 1.78 on the fitting). On the 8.18-second go (one quart of Nitro-XD) the response time was faster than on the 8.12-second go (two quarts of Nitro-XD). This leads us to imagine that the second quart (bringing our combination to 10%) would possibly’ve added extra horsepower, and particularly some additional low-end grunt to get us off the road faster. Every time we added extra Nitro-XD to the tank, the truck went 0.06-seconds sooner. We considered making an attempt a 3rd quart after the 8.12-second go, however the monitor was on the verge of closing and we didn’t wish to hot-lap the truck. For the sake of hypothesis, and since we’ve proof that the Nitro-XD dropped our E.T.’s by 0.06-seconds every time we added a quart, a 15% combination may’ve probably gained us one other half a tenth or extra.

AFFORDABLE ADVANTAGE

When it boils right down to it, it’s important to determine if it’s price it to delve into making an attempt totally different fuels and components to provide you that little one thing additional. By the point taxes and delivery prices had been added in, we had $90.09 within the Scheid Diesel excessive output gasoline and $95.00 within the Nitro-XD. All mentioned and executed, that $185.09 confirmed a 9 hp achieve on the dyno, after which improved our eighth-mile elapsed time by 0.12 seconds. These positive aspects, whereas minor, had been additionally achieved with none tuning tweaks in any respect. To us, that’s an inexpensive value when you think about we didn’t should improve injectors or turbos—or threat hurting the engine by bumping up timing. We merely elevated the standard of gasoline the engine was ingesting, made extra energy, and went sooner.

We’ll admit that gaining a tenth of a second won’t sound like a lot within the eighth-mile, however it might be the distinction between a truck that runs 12.1’s or 11.9’s within the quarter-mile. That’s large in our ebook. In the event you’re in search of an edge in competitors—be it that little one thing additional on the drag strip, an added punch on the dyno day, and even an additional foot or two within the filth—both of those two merchandise can get you there.

While our 1997 F-350 test mule had a parts combination capable of making 600-rwhp, the 195,000-mile stock bottom end 7.3L under the hood had to be tuned conservatively in order to stay in one piece, and remain a reliable daily driver. With an owner not yet willing to spend money on a built engine, not wanting to bump up timing any more (harder on parts), yet wanting to go faster, there was really only one thing left to try. And that’s exactly how the idea for this test was born. — Whereas our 1997 F-350 check mule had a components mixture able to making 600-rwhp, the 195,000-mile inventory backside finish 7.3L below the hood needed to be tuned conservatively in an effort to keep in a single piece, and stay a dependable each day driver. With an proprietor not but prepared to spend cash on a constructed engine, not eager to bump up timing any extra (more durable on components), but eager to go sooner, there was actually just one factor left to attempt. And that’s precisely how the concept for this check was born.
