2008 MSA British Drag Racing Champion Enjoys Lucas Oil Support
Philip ‘Bert’ Englefield was crowned MSA British Drag Racing Champion at the conclusion of Santa Pod Raceway’s UK National Finals over the 27-28 September weekend.
The Motor Sports Association is the UK’s official governing body of motorsport and sanctions national championships in many different disciplines. Its designated championship class in drag racing is Pro Modified.
Englefield is a veteran drag racer who graduated to Pro Modified in the class’s infancy in 1988. In June, he won his first race for several years and, with it, took the lead in the MSA points.
His final steps to the title at the National Finals were less auspicious, though still dramatic. Surprisingly unqualified after three attempts on Saturday, Englefield’s successful, last-ditch blast in Sunday morning’s final session produced engine damage which could not be repaired in the short time before the opening round of eliminations. Fortunately Englefield had accumulated enough points during the five-race season to hold off the eventual race winner, Graham Ellis.
Pro Mods are violent and unruly machines and every trip down the track is a fresh thrill ride for Englefield. His car’s bodyshell, a 1938 Ford Coupe replica, cloaks a pure-bred racing chassis and a supercharged, 8.5-litre V8 engine which burns methanol and generates as much horsepower as three Formula 1 Grand Prix cars.
Earlier this year, Englefield and his BA Racing team, headed by crew chief Andy Wright, installed a new motor from the leading American manufacturer, Brad Anderson Enterprises, and a fuel system from US developer Darren Mayer Performance Engineering. Lubricated by Lucas Oil, the new combination carried Englefield to victory at Santa Pod Raceway’s Summer Nationals and a career-best elapsed time of 6.552 seconds to add to his 215.15mph terminal speed mark.
Englefield and the BA Racing team have enjoyed support from Lucas Oil for four years and can now enjoy a well-earned rest before resuming development work on the car. Englefield’s defence of his MSA British Championship hits the track at Easter 2009 and the countdown has already begun.

Stawicki Pleased with ADRL Debut
Mike Stawicki Racing had a successful ADRL debut at last weekends Gatorz Ohio Drags in Norwalk, Ohio. Stawicki’s G-Force Race Cars inc. built 67 Camaro was one of five roots powered Pro Extreme cars to qualify and the only IHRA legal car to make the field and advance into second round.
Stawicki stated, “This is a fun deal over here at the ADRL. The amount of track time you get to spend in a two day period is great. The competition is stout in all classes in the ADRL. The staff was glad to have us and made us feel welcome and we ran well. All in all, it was a good experience”.
Stawicki qualified in the 10th spot with a 3.98 @ 187 Mph and he took out Gary Irving in the first round with a 4.02 @ 185 Mph. That win paired him with Bubba Stanton in the Widowmaker Corvette. Stawicki put a slight holeshot on Stanton .036 to .047, but Stanton’s screw compressor power drove by Stawicki at the 200 ft. mark with 3.86 @ 195 Mph to Stawicki’s 3.97 @ 185 Mph. Co- Crew Chief Jon Salemi confirmed “We came to this race to improve on getting our car down the race track with our new M5-X3 Supercharger. Between the new blower and clutch combination, we have a great race car right now. We are really excited about our upcoming events.”
The team will travel to Grand Bend, Ontario next weekend to compete in the 3rd Annual Thunder by the Beach PMRA Event Aug 30-31 followed by the IHRA Amalie Oil North American Nationals September 5-7 in Epping, New Hampshire.

Hossler Wins 3 In Row
Although rain shortened qualifying at the Super Chevy Show, it did not dampen the efforts of Hossler Duncan Racing, who for their second Super Chevy Show in a row grabbed the top position. Alex Hossler’s Z06 Corvette took the top spot with a 4.03 in their one and only qualifying attempt.
In the first round of eliminations Hossler took on Jerry Hunt. Hunt broke during the burnout to leave a solo run for Hossler. Hossler took the tree and shook the tires early in the run. In round two the Chris Duncan built Z06 took on Bruce Stedry. In a great display Hossler ran a 4.01 at 183 MPH to take out Stedry.
The final was set, Hossler versus Ken Walsh. When the tree came down Hossler got a 3 tenth advantage. At 150 feet out Hossler shook the tires and had to peddle the car, and shortly after so did Walsh. At the finish line Hossler’s 4.10 took out Walsh’s quicker but losing 4.08. The win makes it Hossler’s 3rd in a row.
The team will be back out in two weeks running at ADRL Norwalk, this will be the teams second ADRL outing of the year.

Hot DMPE News to Kick off Summer Racing
DMPE Top Sportsman racer Craig Fahl, from Shelbyville Michigan, laid down some impressive performances at the recent IHRA Motor City Nationals in Milan, Michigan. Fahl was #1 qualifier with a 6.54 @ 209 MPH run. Fahl then took his 2001 DMPE equipped Camaro to a first round win in the quickest and fastest sportsman doorslammer class in the world. Fahl continued through eliminations and ran a personal best pass of 6.49 @214 MPH, but unfortunately his day came to an end with a red light start. Regardless Fahl was pleased. He stated, “It’s tough to “dial in” and bracket race one of these blown door cars, but we did well with limited runs. Darren and his guys at his shop have helped me a great deal with my combo. We are getting much more efficient with our tune up now and a 6.49 is a stout run for our Torque Converter, Big Block Chevy combo. I look forward to improvement throughout the year”.

In other DMPE News Alex Hossler made his ADRL debut in his Chris Duncan Race Cars built DMPE powered 2006 Pro Extreme Corvette. Hossler rolled into the Pro Extreme Class as what some people would call an underdog. As Hossler made steady improvement through qualifying competitors started to take notice of his “Roots” powered Torque Converter equipped entry. Hossler’s on and off the throttle 4.05 @ 177 MPH run netted him the 11th spot in the tough field. 1st round bought a bye run, as Raymond Commisso was not able to make the call, as he made contact with the wall on his last qualifying run. Hossler laid down his personal best with a 4.02 @ 182 MPH. An excited Hossler said, “This car is showing real potential. I’d like to thank Chris from Duncan Race Car as I could not do this without him and also Jon Salemi from DMPE, as he has put together our power package and helped us with the track tuning. The weather did not cooperate with us in the end but I know there is more left in this car. With only 4 runs on this new engine I’m real pleased”. The Hossler & Duncan team plans to compete at the next ADRL race in Tulsa, OK June 20-23. Pic Roger Richards
To wrap up our Summer News posts Mike Stawicki made his 2008 season debut in fine fashion splitting a final round birth at the PMRA race at New York International Raceway Park. Stawicki was the class of the field as he captured the pole position with a 4.12 @ 183 mph. The weather conditions were less the favorable with corrected altitude in the 4000 ft range and a green race track, Stawicki marched through eliminations with a pair of 4.04 runs and a birth in the final round. Unfortunately the final was not run due to dew setting in on the track as time passed into the evening. Fellow competitor Bruce Boland the Stawicki team decided to split the purse as they felt the track was unsafe for competition.

DMPE Inc. /C.G. Composites Introduce New MK 5X LT Carbon Hat
DMPE Inc. along with manufacturer C.G. Composites (England) are proud to announce another weapon in their arsenal of carbon fiber injector hats. The redesigned MK 5, now dubbed the MK 5X LT. The new MK 5X LT features new improvements to a design that has stood the test of time. The MK 5 hat has been a staple in the supercharged racing world for over ten years to date.
The new X design features a spread front bolt pattern to remove the bolts from the short turn area and an improved long turn area, which helps decrease turbulent air and smooth the air flow into the rotors. The hat also includes a 65 square inch blade opening. Bottom openings will range from 9 inches to 10.5 inches. True to C.G. Composites form, we have also scalloped the bottom side of the blade area for increased air flow. This hat is a comparable model for the racers who prefer the classic 3 blade design with all the features that have been found to make horsepower gains in our other designs.
The hat is available immediately and exclusively through DMPE Inc.

DMPE Inc. New MK 8 LT Thunderbird Carbon Fiber Injector Hat
Darren Mayer Performance Engineering Inc. along with manufacturer C.G. Composites (England) are proud to announce the latest in Carbon Fiber Injector Hats the MK 8 LT.
The new MK 8 LT features new advances in air flow and proper port construction above the supercharger inlet port. Mayer explains, “It’s been a very exciting year to say the least. Development has been the forefront at DMPE in all regards. The new MK 8 LT moves our product line one step further forward. Carlo from C.G. Composite’s is a true craftsman and it really shows in this piece”.
The hat which features a 65 square inch blade opening, captured set back blades, spread front mounting points (for both air flow and for ease of mounting), and CAD designed inner radii to properly feed the supercharger inlet port. Bottom openings will range from 9 inches to 10.5 inches. Gandolfi’s states, “It’s actually simple thinking when it comes down to it. We want non-turbulent controlled air entering the rotor cavity. The way the air enters the passing rotor is the key, and when we improve the rotor fill we increase the engines horsepower potential.
The hat which has already gone into process is available immediately and exclusively through DMPE Inc.

DMPE Release's New Fuel Management Block
Darren Mayer Performance Engineering Inc. adds to its ever-growing list of specialty products by manufacturing the first modular designed fuel management jet and valve actuator system. Knowing that fine tuning is the difference between winning and losing, we have developed a fuel management system that can be tailored to your specific needs. This product was developed from tuning blown alcohol cars and the need to gain the most important competitive edge.
The new DMPE fuel management block is a modular design in which the racer can add more fuel management control as needed. The basic unit can be simple as a single controlled jet, and as your needs increase so can the amount of fuel management. Additional management sections can be inserted to expand the management log infinitely. While the norm is a three control log, we have demand for four and even five controlled jet systems, and now this is achievable with our cost effective fuel block system. Secondary to the control is the unit’s compact design. It has no bulky fittings or potential leaky manifolds. The DMPE unit requires one -6 line in and one -6 line out. We also have allowed provisions so it is possible for these lines to enter or exit from any side of the unit, to further add to ease of fit into today’s modern compact racing environments.
The DMPE modular management blocks are 3D designed and CNC machined to ensure exact fit and function required by today’s racers.
What is a Expandable Modular fuel management log? The name makes it sound difficult and technical, however it is very simple. The fuel log is a means of controlling flow of a fluid, in this case methanol. It is done by giving a tuner the ability to open or close jets as you choose, in the order you choose.
Why would you want to do this? It might be specific to the type of racing you do, but after learning how the system works you might find it can be used for other forms of flow control also.
Have a look at a couple of examples where and how a fuel management block is used.
Top Alcohol Funny Car / Supercharged Pro Mod
(In our example we will use a 3 stage jet log with a .080"jet in Position 1, a .060" jet in position 2, and a .030"jet in position 3)
A funny car normally runs a 3 speed transmission. Each gear loads the motor differently. It is easy to consider there is less load on the engine in low gear than there is when the car is in high gear. (Less gear multiplier) Therefore it’s easier to understand that the engine will require more fuel in high gear than in low gear.
In this situation we would have a 3 jet log installed (jets as indicated above) and the fuel system set rich allowing for the burn out and also staging the car.
We will have a switch under the clutch pedal "or" under the throttle peddle telling our fuel control the run has started. (We will call this W.O.T. for wide open throttle).
At W.O.T. we will open the first jet. Knowing the motor is rich and needs to be cleaned up we will open jet #1 (.080" jet)
At the fuel log the .080 jet is opened and fuel bypassed from the engine and leans the fuel curve. Cleaning the motor up and allowing it to accelerate freely.
Now as the car is shifted into 2nd gear we will close the .080 jet and open the next jet in the log order (jet #2).
In our example we have an .060 jet in the 2nd jet position. Now we have richened the motor by .020". We did this to give the motor fuel back knowing it is under a greater load than previously seen in low gear. Also, we know that cylinder head chamber temperature is rising as well and this will require fuel to control.
Now the car is shifted into high gear. We now close the .060 and open a .030 jet. Again we have richened the motor knowing the load has again increased. The multiplier in the trans in now 1 to 1 (no multiplication) and we are also aware that we have plenty of chamber temperature we need to deal with, and lastly aerodynamic drag is at its greatest point as the car is well past 200mph.
In this example we used the fuel log to control the engines fuel requirements as the car progresses down the race track. It allows us to have a "tune up" for each gear as we can see each gear gives us a new situation we need to tune about.
Many experienced alcohol tuners will use 4 and 5 jets on top of the 3 jet system allowing them to lean and or richen specific areas within each gear as they see necessary on there specific situation. This gives tuners control to control the fuel flow in as many ways as they feel necessary.
Example #2
Tractor pulling
A tractor might use fuel management to slow the wheel speed down as the motor gains chamber temperature and starts running hard. Wheel speed while pulling the sled can be a bonus in certain conditions and to much wheel speed can cut your pulling distance in other conditions. Some pullers use the fuel log to richen the motor in specific spots while pulling as conditions pertain. An example would be giving the driver a button that closes a jet; normally it would be the pump loop jet. When the tractor gets going and the engine cleans up and gets lean (more power), it may have the power to develop too much wheel speed. The driver when feeling the excessive wheel speed can touch the button and richen the motor calming it back down allowing the wheel speed to slow to a controllable speed and regain traction.
These are just two of many in field uses of the DMPE Inc. modular fuel block can be used. While some tuners want five or more jets to control, many only want one or two. The new modular fuel block allows tuners to tailor this part to meet there needs

Croker Blast's to New Record
Adam Croker, of Perth Western Australia, set a new standard for roots style blown alcohol dragsters at the first meeting of the ‘07-‘08 race season at the Kwinana Motorplex in W. Australia on November 3, 2007
Croker, who stepped away from Top Doorslammer racing for a year or two to concentrate on DMPE Down Under, smashed the previous AA/D record of 5.82 with a remarkable 5.67 @ 247 mph on just his second hit in the car. Croker stated, “I had no doubt that in time we could run very well but to do it as soon as we did, is what I’m so happy about. Darren and Jon from DMPE Inc. told me we had awesome power in my Doorslammer last year, but we just could not make smooth runs. I guess they were right! Now my team owns the title to the quickest and fastest roots powered alcohol dragster in the world”.
Croker unfortunately fell victim to parts attrition in the next round as the 2 step solenoid cracked a fitting and leaned the motor causing considerable damage. The disappointment was even greater when he found out that it was .05 faster to the 1/8 mile mark than the 5.67 run and the fitting broke at 800 ft. The team hopes to have the engine repaired in the next 3 weeks and be back on track and improving on the newly set record.
Croker Racing thanks the following companies for their support: Croker Construction, DMPE DU, R&R Contracting, Brooks Hire, N.K. Contractors, Mineral Transport and Link Low Loaders.

DMPE Inc Goes "Down Under"
DMPE Inc. of Stevensville, Michigan has opened its doors in Perth Australia. DMPE’s mission is to service the needs of the many supercharged methanol burning customers in the growing sport of drag racing in Australia. The obvious name of DMPE DU (Down Under) seemed appropriate for the adventure. Upon partnering with Adam Croker of Perth, WA the idea became a reality. In order to offer the Australian customers, the same quality of service and knowledge, it was in order to transplant Croker to the U.S. for training at DMPE Inc.
Croker, spent a month in Michigan at DMPE Inc, and has undergone complete training with respect to servicing and repair of roots style superchargers, fuel systems and ignitions. Croker states, “It was an intense undertaking to say the least. I wanted to come back to Australia with as much knowledge as possible. Darren and his great staff of employees have done a superb job teaching me all the vitals of proper servicing and repair to all types of roots superchargers and of course they are at my disposal if I ever need to be guided or assisted”.
Not only will DMPE Down Under provide the needed supercharger service and repairs but also offer a complete parts stocking list for blown alcohol racers. Mayer stated, “We have worked with Australian racers in the past and are aware of the difficulties they face receiving quality parts, service and technical knowledge. We have trained Adam on repairing, servicing and modifying all types of roots superchargers intensively. We even built the needed specialty tooling and shipped it all to Adam to ensure the work is identical in quality as received from DMPE Inc. in the U.S.A”.
DMPE DU will inventory items to assist racers needs and help reduce lead times on many desired parts. Items include NGK Spark Plugs, MSD Ignition, common ring and bearing packages, common rod and piston packages and much more.
DMPE DU will be based in Perth, WA, but will serve the entire country. For a complete list of parts and services please contact Adam Croker/DMPE DU at 0409-486-907 or email adam@dmpeinc.com

DMPE Inc. Supercharger Gel Lubricant
Darren Mayer Performance Engineering Inc. adds to its ever-growing list of specialty supercharger products by manufacturing the first specifically designed Supercharger Lubricant and Lubricant remover.
The DMPE Inc. Supercharger Gel Lube provides a better performing supercharger by addressing Teflon wear and leak path control. While extended Teflon / Nylatron wear through proper lubrication extends supercharger performance longevity,
the Gel’s ability to cling to the rotating rotors and internal parts also increases the efficiency of the unit by filling up the clearance between moving parts. It tightens the seal between rotor to rotor, and end frame to rotor clearance thus allowing the supercharger to increase efficiency by reducing leak paths. This also reduces costs by decreasing time between overhauls.
The gel lube is not affected by methanol like many supercharger lubes, therefore provides a better, longer lasting seal.
The Gel Lube Remover was specifically manufactured to remove the above lubricant. The lubricant was designed to hold up to most all solvents and methanol, allowing the lube not to be washed away from the rotors, rotor bores and internal supercharger surfaces.
Because of this it requires a “remover” to cut the supercharger gel at time of re-striping. It is important to remove all traces of the lube from the Teflon grooves so that the Teflon does not pitch itself out of the rotors after overhaul because of any remnants of the slippery lubricant.
Once all the rotor stripping is removed from the rotors, the dovetails should be sprayed with the remover to ensure removal of all gel lube. The Teflon is then pulled into clean dry grooves (dovetail) and the supercharger can then be re-assembled.
After the supercharger is re-assembled, liberally apply the supercharger lube into the rotor cavity. We suggest that it is applied once a day, usually on first start up. For more info and pricing please click HERE for Lubricant. Click HERE for
