DMPE inc. Introduces Improved High Velocity Rotor Shaft Seals
Dmpe has been spending many hours rethinking and developing our line of performance products to offer the best possible product to our customer. While improving our line of supercharger units, we have made time to address the need for an improved sealing element for the gear cavities, and also the drive snouts. The new alcohol shaft seals have proven themselves in our dyno testing without failure. They also have shown improved ability to withstand the increasing surface speeds and pressures that our present line of seals were struggling to handle. We are pleased with the seals improved performance and are now introducing the seal design into our snouts as well. The snout seals are in production at this time. The new seals are based on aluminum housings and are sold under part number 100-002-99-331. The seals will retrofit to all Kobelco superchargers using the small alcohol shaft. However a small modification will be required to the Kobelco shaft to allow installation. DMPE will provide proper instruction in these situations. This modification labor will not be required when installing on any of the DMPE X3 rotor lines.

DMPE Inc. Unmaskes the M5
This is the best blower money can buy bar none. Here are the reasons why!
The M5 is a "modular" supercharger. Modular meaning the top and bottom of the supercharger are removable. The top and bottom sections of the unit also house the inlet and discharge ports. This allows the racer to tune/change the blower to his particular needs. DMPE Inc. developed this blower while dyno testing and modifying other units to meet customers needs. A huge advantage is the tune ability of the unit and the decreased time between blower tests. You can drastically change this supercharger without removing it from the car. Remove the hat, hat spacer, then the top insert plate. Once removed the whole top of the unit is exposed. Yes, you can see most all of the rotors when the top plate is removed. Insert your new billet top plate, reassemble and you are ready to test (or race). The bottom plate works on the same principle except you have to remove the unit to change the bottom plate/port. Now that testing and prototyping are complete we have billet top plates that accomplish different goals. The customer can move horsepower and torque around as you need it for your car, weather, or over-drive needs demand. The M5 is 100% 3D modeled and machined. This allows us to design in the computer, computer simulate and test the unit in virtual space. This also allows us to machine in ways never before possible. The M5 is 11 pounds lighter than the Kobelco and 3.5 pounds lighter in rotating mass. (rotors and drive train)
When you purchase the M5 you obtain the blower (Billet top and bottom plate to meet your requirement), snout drive, 14.2 restraint, and billet hat spacer. The cost is $13,500.00. When comparing the price you must compare to purchasing a Kobelco, Littlefield or PSI unit, paying a company to modify it to meet your needs, and also purchasing a hat spacer, and also the restraint plate. Once you have weighedyour costs and the ability to change the unit the value shines.

DMPE Releases the M4
(dubbed the new school blower for the masses)
This is a lower cost DMPE version of the standard trend in blowers. As we all know the insert at the rear of the inlet port makes power over the stock cased 14-71’s. Having the ability to change the inlet size is a tuners advantage with both air and track conditions. Each inlet size also nets a different power curve as the engine dyno shows us. Of course not to mention the inlet "shoes" are also sized for different overdrives as well.
The downsides to the inserts that are machined into the stock cases are as follows.
-Bore tends to distort when you machine the material out for the shoe pocket.
-No real material to attach the shoe properly (set screws are normally used in the same manner Teflon is retained as there really isn't enough case material to do it correctly.) Case cracking in thin areas is sometimes an issue as well.
While just released on 9-29-08, the M4 is officially for sale. This unit is also completely 3D designed and machined. It enjoys a 7 lb. weight reduction over a stock Kobelco Superman, which we will commonly compare to as the industry standard. The inlet and discharge port have been moved and redesigned to increase in the performance of the unit also making it the best blower money can buy in this specific price range. The M4 sells for $8800.00. This price includes the blower, the drive snout and the requested inlet insert shoe. Insert shoes are available from DMPE in shapes and sizes we have designed and dyno tested. We are also offering them in blank form. This allows you, the customer, to try, test, or just play around with your own ideas for inlet design. The M4 design is aimed at offering a blower that will parallel the performance (or out perform) the modified blowers in there stock form. The M4 also removes all of the above listed troubles racers are having with modifying stock units. It is aimed at a lower cost than the M5 to meet budgeted race teams. DMPE Inc. offers injector hat spacers to complement each inlet shoe we sell and of course custom designs are available to suit customer’s needs.

Wilmes Plans, Attacks and Cashes In
Kirk Wilmes of Altus, Oklahoma may be young but sure drove like a seasoned veteran at the 4th Annual SCSN at “The Strip” at Las Vegas Motor Speedway. Wilmes opened qualifying with a 6.21 @ 231 mph only to better it through four rounds of qualifying with a 6.16 @ 232 mph. That was good enough for the #2 spot on the 32 car ladder.
The 24 year old slashed through the Pro Street field by killing them with consistency. The team’s only hiccup was in the first round where a dropped valve almost cost them the race. Luckily it decided to give away far enough into the run to propel the car to a win, although it was coasting from 4.06 seconds to the finishline. Subsequent runs of 6.19 and 6.24 carried the team through to the semi finals where the event was cut to a 1/8 mile race as the air temperature flirted with the high 40 degree mark. The KW Motorsports team continued to march to the win with back to back 4.09 runs both at over 180 mph. An overjoyed Wilmes stated, “I don’t even know where to start…..this is so awesome!!! I have to thank my parents Jeff and Kim Wilmes. Without their support, I couldn’t have this opportunity. My crew guys and great friends, Adam Braddock and Copus Lester, Louis Boyd for our engine program, Jim Salemi (G-Force Race Cars Inc.) for building a great car and Jon Salemi (DMPE Inc.) for our M5 Supercharger and fuel system. We couldn’t have done it without all of these people.”
Team owner Jeff Wilmes said, “I’m just proud of our team. The Salemi brothers keep my guys safe and are teaching them how to race and be a team. I’m just a proud guy right now. We won as a team and that makes it all worth it”.
The KW Motorsports team plans to run the TOPMA series next year as well as some Street Car events and a possible appearance at some ADRL races.
The KW Motorsports team thanks the following companies for their support: Wilmes Auto Group, Louis Boyd Racing Engines, G-Force Race Cars Inc, DMPE Inc, Cynergy Composites, and Scott Jahren Paint.

Bogolo Blast's to 5.70 @ 244 MPH at Rockingham with M5
Tony Bogolo from Hamilton, Ohio turned Rockingham Dagway on it's ear on Saturday evening by running a #1 qualifying shot of 5.70 @ 243 mph. Bogolo did it in fine fashion with a DMPE 14-71 M5 superchager with high overdrive provisions. Bogolo stated, "This is a long time coming. Ever since we got the new M5 on this car I knew it could run. It was just a matter of getting the combination right. I gotta hand it to my friend and tuner Rick Hickman along with Jon and Darren from DMPE. Without everyone's help it couldn't have done this". Unfortunately Bogolo rolled the lights in the opening round and turned on the red light. Bogolo, onwer of Ram Jet Racing Products, remains very optimistic for the 2009 season.

Hossler Sets NMCA Record and Wins Black Sunday Event
Following Hossler Duncan Racing's NMCA debut where they set the Pro Street record at a 6.26 @228 Mph they were back at Gateway International Raceway for the UBDRA's Black Sunday Quick 16. The team planned on making a test hit on Friday, but shortly before they headed to staging the clouds opened up and testing for the rest of the day was canceled.
With October weather in St. Louis it was obviously tricky for teams getting the power to the ground. Hossler's Z06 went into shake about 100 feet out during the first qualifier. In the second round the Chris Duncan Race Cars Corvette went straight down the the 1/8th mile running a 4.01 at 186 MPH which would qualify him number two. In first round eliminations Hossler had to take on Donnie Little's 63 Corvette. While Little got the holeshot, Hossler passed him running a winning 4.08 second pass.
In the second round Hossler had Mike Bell. Hossler's converter driven entry again went straight down the track with no shake, to run a 4.03 to take the win. In the semi final Hossler Duncan Racing had to take on Duane Rister. Both cars made clean passes, but again the Z06 Corvette of Hossler took the win this time running a 4.02 to take the win. The final was held shortly after the sun went down on Sunday evening. Hossler was matched up with the Chris Duncan Race Cars prepared '67 Firebird of Cody Barklage. Hossler for the first time in the day was not the favorite to win. When the green came down both cars erupted down the 1/8th mile. Barklage went into severe tire shake, which allowed Hossler to motor down the track to an easy win. When the scoreboard lit up 3.980 at 186.79, which gave Hossler not only his 4th win of the season but his first 3 second pass. Hossler stated, "I really gotta give it to my crew. Chris Duncan and the boys gave me a car that went down the track every pass and got faster everytime. It was flawless. I also wanna thank Stawicki Racing for building us a reliable powerplant and Darren Mayer for the great M5 Supercharger and tuneable fuel system. We've really had a great season."

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 increasing 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
Lubricant Remover.
