S&S Diesel Motorsport Featured In Dragzine

S&S Diesel Motorsport’s common rail diesel technology was recently featured in a very informative article on Dragzine! 

“Your father’s diesel engines were known for being dirty and loud, and while unrivaled in longevity and efficiency — at least relative to their spark plug-equipped counterparts at the extreme end of the spectrum — they weren’t exactly all-out performers in the racing world. But diesel performance has come a long way, thanks in part to the efforts of companies like S&S Diesel Motorsport, who have driven technological leaps in fuel systems and engine management systems. The result are efficient, clean-burning, and quiet race engines capable of producing the kind of horsepower to run with their gas and methanol-fueled competitors.” – Andrew Wolf

Why Choose the S&S 6.7L Ford Power Stroke CP4.2 Bypass Kit over the Cheap Copies?

Why should you pay more for the S&S 6.7L Ford Power Stroke CP4.2 Bypass Kit?

  • S&S Diesel Motorsport designed and developed the first CP4 bypass kit for the 6.7 Power Stroke. Though we are the first to develop one for the 6.7 Power Stroke, we can’t take credit for the idea. We took inspiration from a kit that was used in Europe on a VW engine. We do our best to state the facts and not make false claims.
  • Every other lower-priced kit on the market is a copy of ours, at least the aluminum block is. Even if the bypass block is copied exactly, we can’t attest to the machining quality and tolerances of the other kits. The aluminum bypass blocks in the S&S kit are machined in the USA, to exact tolerances.
  • Our kit includes a special o-ring that grips the bottom of the bypass block, which makes installation easy and ensures a proper CP4 to bypass block seal.
  • Being the first to market many years ago has given us time to discover potential deficiencies in the hose material, and make the needed changes. We currently use a proprietary hose material that will hold up over time, the other knock off kits do not use the same material. That is an example of developing products versus copying products. We are always trying to improve the product; others are just trying to make easy money with their own style of R&D (Rip-off and Duplicate).
  • Our kit is the only one on the market that is CARB-compliant (#D-756-1), and each kit will come with a CARB sticker for the engine bay. Since we developed the kit, we spent the extra time and money to make sure our customers would not take on any legal risk by installing our kit.

The points above make our kit stand out from the ones that sell for less, and show that $360 is a very reasonable price for the original S&S 6.7L Ford Power Stroke CP4.2 Bypass Kit.

The Facts of Highly-Modified S&S Diesel Motorsport 6.7 Cummins Injectors

Performance

We would like to take the time to lay down the facts of highly-modified S&S 6.7 Cummins injectors. Some may think that 250% over-stock fuel flow is the limitation of the 6.7 Cummins injector body. While we can’t speak for our competition, this is not true for S&S Diesel Motorsport 6.7 Cummins fuel injectors.

There are a few things to consider when using the % over stock categorization that the aftermarket has adopted. The % over number is calculated by flowing the nozzles by themselves, not the complete injector. For this reason, we would prefer to categorize our injectors by what their exact flow numbers are, but this is difficult without using a standard rail pressure and energizing time. For the time being, we also categorize our injectors on nozzle flow, yet we include a detailed flow sheet that shows the output of each complete injector.

We test our nozzles with the needle out, using the industry-standard Viscor SAE-J967 calibration fluid at 100 bar with a constant temperature of 40 degrees Celsius. On our test equipment, a stock 6.7 nozzle flows 1,200 cc/min and our largest 6.7 nozzle flows 6,600 cc/min, which we classify as a 450% over nozzle per the following equation: (6,600 – 1,200)/1,200 = 4.5 or 450%.

Since we are a company founded by OE engineers, we prefer to use data to prove our point, rather than expecting the diesel industry to blindly take our word for it. So, let’s compare the actual fuel delivery per stroke of stock 6.7 Cummins injectors and a set of our 6.7 Cummins injectors with 6,600 cc/min nozzles, more commonly known as 450% over injectors. Late-model (‘13-‘18) stock 6.7 Cummins injectors flow slightly more than the early-model (‘07-‘12) 6.7 injectors, so we’ll use both for our test.

OE Bosch 6.7 Cummins Injectors

 

S&S 6.7 Cummins 450% Injectors

We can compare output in mm3/stroke at 1,700 µSec for all injectors. Output of the early 6.7 Cummins injector is 150 mm3/stroke, output of the late 6.7 Cummins injector is 165 mm3/stroke, and the average output of our 450% set is 632.5 mm3/stroke. Below are calculations for the increase in fuel delivery per stroke of both variants of stock 6.7 Cummins injectors:

Increase from Early 6.7 Injector – (632.5-150)/150 = 3.22 or 322%

Increase from Late 6.7 Injector – (632.5-165)/165 = 2.83 or 283%

When comparing the stock 6.7 injectors to our 6.7 injectors with 450% over-stock nozzles, the nozzle flow increase and actual fuel delivery increase are not the same, yet a 250% increase in actual fuel delivery is NOT our limit. Moreover, a 322% increase in fuel delivery through the complete injector is what our 6.7 Cummins injectors with 6,600 cc/min nozzles and accompanying body modifications can do.

 

Consistency

Some people may be under the impression that consistency is impossible for highly-modified aftermarket injectors. This is also not true for S&S Diesel Motorsport injectors. Below are datasheets for 42 different 2,000+ horsepower capable injectors with no more than 2.12% variance per set, and 5.9% total variance across all 42 injectors.

7 Tightly Balanced Sets of S&S 6.7 Cummins 350% Injectors

 

42 S&S 6.7 Cummins 350% Injectors with 5.9% Total Variance

The Bosch factory spec at the same rated point on stock injectors is 8% total variance. Not only are S&S Diesel Motorsport 6.7 Cummins injectors capable of delivering roughly 322% more fuel than stock injectors, they are balanced to tighter tolerances than stock injectors.

S&S Fuel Systems and Electronics are the Winning Combo of the Scheid Diesel Extravaganza 2019

The Scheid Diesel Extravaganza (SDX) is the longest running and most prestigious diesel truck event in the world. There’s a little something for everyone at SDX with pulling by Lucas Oil Pro Pulling League (PPL) and the Outlaw Diesel Super Series (ODSS) for drag racing.

The PPL Super Stock Diesel Truck class is the gold standard of diesel truck pulling, nothing with a diesel engine powering four wheels pulls more weight. Nearly all of these 3,000 horsepower machines are Cummins-powered and mechanically-injected, regardless of what body is used. There are a few #SSfueled rebels that stray from convention in favor of progressing common-rail diesel technology. Though Craig Dickey (Cummins Killer 2) and Chris Galati (Turbo Cowboy) did not break into the top ten, they should be recognized for their common-rail innovation efforts in diesel truck pulling’s top class.

Over fifty of the nation’s top PPL Limited Pro Stock trucks descended on Terre Haute, IN on the hunt for a prestigious win at the Scheid Diesel Extravaganza. On Friday night, Garrett Loucks utilized the complete S&S fuel system and electronics package to push “Un-Locked” to 321.31 feet for the win! Other Friday night top ten performances for Team #SSfueled were Jesse Knight (Hillbilly Bone) securing 5th, Jordan Kinderman (Cummin Get It) with a 9th place finish and Colbi Seth (Sketchy Hooker) just half-a-foot behind for 10th place.

Team #SSfueled infiltrated the PPL Limited Pro Stock top ten on Saturday night as well. Brian Shew (Iron Maiden) earned 3rd place and Colbi Seth (Sketchy Hooker) improved to an 8th place finish.

For the second year of the class at SDX, PPL Pro Street Diesel pulled in thirty-five trucks and only the top ten of each day would go on to pull in the big show at night. Scott Barcus (Inline Only) made the cut both nights, earning 2nd place honors on Friday night and an 8th place finish on Saturday. Also on Saturday night, Ray Jay Rindt (Wicked White Knight) secured 2nd place and Lee Stiltz, a vocal supporter of S&S Diesel Motorsport, flogged “Privileged” to a 3rd place finish.

Many teams found success in Outlaw Diesel Super Series drag racing action by using S&S injectors, pumps, and electronics. Done Right Diesel’s Ben Shadday earned Runner-Up honors in ODSS Pro Mod while using a pair of S&S 14mm CP3 pumps. Trusting in the complete S&S fuel system and electronics package paid off for Johnny Gilbert and the Stainless Diesel crew, helping them claim a fourth consecutive ODSS Pro Street victory and locking up the 2019 championship tighter than Fort Knox. Relying on steady fuel from her S&S CP3 pumps, Mindy Jackson won ODSS Outlaw 5.90 for back-to-back wins.

Congratulations to all #SSfueled teams for competing at diesel motorsport’s highest level and thank you for putting your trust in S&S Diesel Motorsport!

Injection Rate Shape and Why it Matters

There’s more to high-performance common-rail diesel injection than nozzle size, at least for S&S Diesel Motorsport. In a perfect world, fuel injectors would open exactly when they are electrically energized, in the real world there are fluid dynamics to contend with, and injection rate shape tells us exactly what the injectors are doing during, and after, the energizing time. Proper common-rail injector nozzle flow is measured using calibration fluid at standardized and tightly controlled temperature and pressure. This is typically published in units of cubic centimeters per min (cc/min) and is presented to the public as a percentage increase from stock flow. Percentage over stock has become the industry standard designation for injector size, yet that number is based off of the nozzle only. In theory, a 100% over-stock injector will deliver twice the fuel as a stock injector during energizing time, but that only accounts for nozzle flow. What if the injector can open and close quicker, or have higher peak flow during the same energizing time? That is where injection rate shape comes in. Rate shape is a curve that shows injection quantity over time for each individual injection event. The area under the curve being the total quantity injected. Rate shape is a tool that we use to first see, and then balance each set of injectors to not only total quantity, but complete injection profile.

This technology is not available to the majority of fuel system manufacturers, and without the ability to see the rate shape, they fall short on balancing when and how the fuel is injected. Since the area under the curve is total quantity, it’s possible for many different rate shapes to net the same amount of fuel. Having control over injection rate shape allows us to build more advanced and precise common-rail diesel fuel injectors that are calibrated as a set for a specific application.

Ryan Milliken Goes Rounds at Lights Out 10, and Takes Back the Diesel Door-Slammer World Record

Twice a year, the world’s quickest and fastest drag radial cars converge on South Georgia Motorsports Park seeking small-tire glory at the biggest door-slammer race in the known universe, Duck’s race. While it may not be the quickest class, X275 is viewed by many to be the most competitive, and Ryan Milliken has been trading blows with the best for the last few years. Most recently at Lights Out 10, where the Hardway Racing team qualified 19th out of 57 cars and made the 32-car show with a diesel-powered door-slammer record pass of 4.458 at 162.7 MPH.

The SS-fueled, Cummins-powered, Nova lined up against number 14 qualifier, Greg Henschell, in round one of eliminations and proved that staging a diesel can be done quickly and effectively. Henschell struck the tires on the line, and Milliken won with a solid A to B pass of 4.507 seconds. The Hardway Racing team earned lane choice in round two against the number three qualifier, Manny Buginga, where they would need all of the help they could get. When the green bulb lit, Milliken was first off the line, then Buginga pulled ahead until the 330-ft mark, when Milliken started to run him down. Milliken improved his diesel door car record with a 4.455-second blast, yet Buginga won the round with a 4.410, and later went on to win the event.

Congratulations to the Hardway Racing team on reclaiming the diesel-powered door car world record and for giving the event winner a tough race!
