BTE Racing Transmissions: Tips from the builders

When building your own racing transmission, there are some absolute rules and tools for a successful assembly.
  • The right parts.
    • Strong, reliable components that are designed for high performance applications by companies like BTE. Always research the company's history and experience with racing transmission design and manufacturing.
  • The right process.
  • The right tools.
    •  Snap ring pliers, torque wrenches, sockets and a good hammer should always be in arm's reach at a building table.


We asked our veteran transmission builders what are some of the tricks that fit between these three foundations that make their jobs easier and the results more successful:
  1. Cleanliness counts! A clean work area and clean parts should be the priority. Any amount of dust, grime, metal shavings, or even hair can cause a moving valve to stick or drag. At BTE, we wash parts in a hot steam pressure washer and also uses solvents and media blasters when required.  
  2. Design a workspace that is comfortable and accessible. A work table that requires you to bend over or reach too far can be a headache (or a backache).  Good, clean lighting is also a must for seeing details on component parts and for making difficult part installations go more smoothly.
  3. The "right" tools for the job are critical, but having a few *extra* tools doesn't hurt.  A lathe for machining pistons, seal installers, ring compressors, an air compressor for testing seals, and a dyno testing machine for trouble shooting are used by our builders every day to help with the perfect assembly. 
  4. Don't forget the assembly lube! A small amount of grease is required for many seal and other component installs. We like Life Automotive's Trans Prep
  5. Think outside the "box."  When troubleshooting, always consider the external forces at work on the automatic transmission. From the electronics to the differential and tires, the automatic gearbox is affected by any out of the ordinary operation from its mated component systems. 
We encourage more racers to manage their own transmission building and service. It's a rewarding (and potentially money saving) experience. Have any suggestions of your own? Please post them to our blog!

Transbrake solenoid tips and troubleshooting

Racing transmission transbrakes rely on tightly wound electric solenoids to activate and release. These tiny mechanisms are actually the same used on bomb deployment systems for air force bombers! Because of their precision design, nature of construction, and the high stress environment in which they operate, they can be hard to diagnose or understand when things don't seem to be working correctly.

  • Ensure that you have a proper ground.  Grounding to the chassis or directly to the battery is preferred. Do no ground the solenoid to the transmission case. There is some evidence that the grounding of the solenoid to the case can cause electrical arcing within the planetary gears.
  • Excessive transmission temperature can affect the solenoid operation. Always monitor your fluid temperatures, and if they rise above 200 degrees during normal operation, investigate and resolve these high levels.
  • The solenoid contains moving pieces and should periodically be removed and cleaned with high pressure air to remove debris.
  • Check battery voltage levels. Also, check voltage of wires leaving any delay boxes or other devices that may be between the battery and solenoid.
  • If the transbrake solenoid seems to be weak or releasing early, try adding small shims between the solenoid and transmission case. We have seen some variance in the dimensions of aftermarket and OEM cases, as well as valve body castings. If the solenoid is too "close" to the valve body and the brake valve pushes the solenoid plunger out too far beyond its effective area, the electromagnetic force cannot overcome the fluid pressure behind the brake valve.  
As always, please comment or contact us if you have any questions regarding your transbrake solenoid.

Luke Bogacki Clinches 2013 NHRA Lucas Oil Super Comp National Championship

Luke Bogacki is still trying to convince himself it’s real. He’s done the math, and he knows that he’s clinched the 2013 NHRA Lucas Oil Super Comp championship. His friends have offered congratulations. NHRA officials have called to confirm that he will represent them as their champion. He wants to believe it, but the gravity of it all just isn’t sinking in.








Growing up in a racing family, he’s dreamed of this moment for as long as he can remember. And he’s come close before, painfully close, to realizing that dream. In 2010 he triumphantly won his final Super Comp event to take the national lead on a tie-breaker; only to watch Gary Stinnett overtake him by less than one round at the final Lucas Oil Series event of the season. Just last year, Bogacki made the trek from his Southern Illinois home to Las Vegas, NV in pursuit of the crown. There, he needed to make the final round of the event to win the title, but fell a few rounds short of eventual champion Alan Kenny.

“I don’t know how many sheets of paper I’ve wasted since September scribbling out who had a chance to catch me and what they had to do,” laughed Bogacki, who has led the national standings since late June. “Between NHRA and IHRA I think I’ve displayed every top 10 number except the one everyone wants. After a while you get conditioned to thinking it’s just not meant to be. I kept watching the standings and waiting for someone to get hot and pull the rug out from under me.”
Racers did get hot. Ray Miller III made a strong run at the title, but will likely finish 2nd. Kyle Cultrera enjoyed a stellar season and made the battle for the title interesting deep into October, but Bogacki’s 676 point score; likely the highest of any sportsman competitor this season, proved too much to overcome.

Bogacki started his season inauspiciously, with back-to-back first round losses at the NHRA Winternationals in Pomona, CA and Arizona Nationals in Phoenix, AZ. He salvaged his trip to the west coast with a pair of solid divisional performances: a runner-up finish at the Phoenix Lucas Oil Drag Racing Series event, and a fourth round loss in Las Vegas (where he also won Super Gas). He then took 2 months away from the tour surrounding the birth of his firstborn son, Gary. When he hit the road again in late May, the new father caught fire.

Following a third round defeat at the Atlanta Lucas Oil Division Series event, Luke drove to his first Super Comp victory of the season in early June at Chicago’s Route 66 Raceway. A week later, he took runner-up honors at the LODRS event in Cordova, IL. He entered the Summit Racing Equipment Nationals in Norwalk, OH as the points leader, and won that event to put a stranglehold on the championship that he would not relinquish. Bogacki finished his points ledger with a quarterfinal showing at the Lucas Oil Nationals in Brainerd, MN and another runner-up at the divisional level, this time in Bowling Green, KY. As the season neared conclusion, Bogacki also added a pair of runner-up finishes at the national level in his Super Gas Corvette, at the AAA Texas Nationals in Dallas and the AAA Insurance Midwest Nationals near St. Louis.

When asked to pinpoint the difference between his championship season and his past near misses, Bogacki offered little explanation. “I’ve been asking myself the same question. It’s easy to chalk it up to luck or good fortune. And I’ll be the first to admit that I found myself in the right place at the right time a lot this year. But I’ve always been one to want a tangible explanation – something with a little more substance than pure luck. The only thing I can say is that I feel like I’ve raced smarter this year than in years past. I always thought of myself as a really good driver, and I was dependent on my ability; but these days I don’t get to race nearly as much as I did five or ten years ago. I don’t know that I’m necessarily worse behind the wheel; but I’ll be the first to admit that I’m not as sharp. That realization really allowed me to put more faith in my car, which has been better than its driver by far, and to keep things pretty simple from a driving standpoint. I feel like I’m a better racer because of it.”

Bogacki points to his 2013 American Race Cars dragster as the biggest key to his success. The 240” American Chassis is outfitted with a 632 cubic inch Huntsville Engine & Performance powerplant that features a BRODIX aluminum block and new SR20 cylinder heads. The motor includes Wiseco Pistons, a Crane Cam and lifters, Jesel belt drive and rocker arms, Milodon oiling system, and Hedman Hedders featuring Nitroplate coating. The engine is lubricated by Lucas Oil products, protected by a K&N Wrench Off oil filter, and surrounded by a J&J Performance Engine Diaper. The combination is topped by an APD carburetor and fuel system that transfers Renegade 116+ Racing Fuel through Earl’s Ano-Tuff fittings and line. The engine, capable of low 7-second elapsed times, is reigned into the 8.90 Super Comp index thanks to a Dedenbear Throttle Stop and K&R Performance Engineering Pro-Cube delay box and throttle stop timer.

Bogacki monitors all critical functions of the machine thanks to Auto Meter’s Multi-Function Data Logger. His combination also features Moser Axles and brakes, an Ohlins shock, BTE “Top Dragster” transmission and converter, Mickey Thompson Tires and Wheels, a B&M shifter, paint design and application from Todd’s Extreme Paint, as well as products from Dixie Racing Products, Nitrous Express, ISC Racer’s Tape, and JEGS. Bogacki also recognized the staff at Charlie Stewart Race Cars, who built his Super Gas Corvette.

Although he admits he hasn’t completely come to grips with the title of world champion, Bogacki’s experience in the sport helps him put his dream season into perspective.
“It’s kind of surreal, to be honest. I grew up watching guys like Tommy Phillips and Scotty and Edmond Richardson race at our local track. They’ve all had great success in Super Comp and they found a way to make a living driving sportsman race cars. That opened my eyes; and for as long as I can remember that’s all I wanted to do. I used to sit in my room as a kid; most kids were playing video games. I had a practice tree set up, and index cards with the names of racers on the front, and a list of their reaction times from National Dragster on the back. I’d run rounds, races, seasons against those flash cards for hours at a time. I bet I won 100 world championships on that practice tree! It’s just hard to believe it’s come true in real life.”

Bogacki thanked his wife, Jessica and their son Gary for their unwavering support. He also wished to recognize his team’s major marketing partners: ThisIsBracketRacing.com and the Motor City Hot Rod and Racing Expo, as well as associate partners K&N Engineering, Tinsley Drilling & Company, C.A.R.S. Protection Plus, Advanced Product Design (APD), JEGS, Mickey Thompson Tires and Wheels, Bill Taylor Enterprises (BTE), and Product Development Group (makers of AirTek Pressure Systems and Flo-Fast pumps).

Powerglide band adjustment tips

The powerglide transmission has a single band.  It is used to hold the clutch drum during low gear operation.  If the powerglide band is not adjusted properly the following things can occur:
  • Band failure (burning of clutch material)
  • Slipping in low gear or no low gear function at all
  • Shift flare between low and high gears
  • Car rolling backwards when the transbrake is applied
The powerglide band should be adjusted to the following specs:
  • Tighten the band adjustment screw to 72 inch lbs
  • Unscrew the band adjuster three and a half turns (3.5)
  • Tighten the band adjustment screw's locking nut
The band should be readjusted on a semi regular basis throughout the racing season.  BTE recommends using a heavy duty band adjustment screw to prevent band failure.  Stock band adjusters can bend and warp under heavy duty conditions.

What are the limits of a factory, stock or OEM powerglide case in a racing application?

For more than 30 years, racers have relied on a variety of OEM parts to complete their cars due to budget or due to a lack of suitable aftermarket parts.  In the last 10 years, this has started to change dramatically with the availability of aftermarket cases, housings, gears, and just about every other high performance transmission (or engine) component.

Aftermarket powerglide cases bring a lot of advantages over stock cores:
  • Greater strength
  • Revised oil channels optimized for racing
  • Improved wall thickness to meet SFI safety requirements
  • Elimination of non essential areas and features for OEM usage
However, stock cases still have plenty of applications in budget and entry level racing.  With the addition of a SFI approved bellhousing and case shield, a stock case be ready for competition.

What are the practical limits for the stock cases?  What are some important tips to remember when using a stock case?

BTE recommends using a polyurethane transmission mount.  Solid, rigid mounts are often too stiff for a powerglide case when a heavy car launches hard.  This will often lead to a crack in the case.

Also, stock cases are more prone to failure if a driveshaft, rear end, or u joint is not properly configured or faulty.

Finally, it is important to monitor line pressure when using a stock powerglide case.  Pressures over 245 lbs can cause leaks or cause cracks to form in the thin die cast aluminum found in some of the various casting versions.

Why is your car moving backward when applying the transbrake in your powerglide?

As a follow up to our previous blog posting, the other common problem with transbrake operation in powerglide transmissions is the transmission moving in reverse when the transbrake is activated.  Again, this can cause the car to roll out of the staging lights causing an instant loss.


Once again, we will review the normal transbrake operation:

  1. You activate the transbrake solenoid in low gear when staging.  The solenoid pushes the brake valve to a position in the valve body that redirects fluid.
  2. Fluid rushes within the transmission to apply the reverse clutch piston and reverse clutches.  This locks the transmission in a 1:1 fight between low gear and reverse.
  3. You increase engine RPM to prepare the car for launch.  The transbrake remains locked and keeps the car in place.
  4. You release the transbrake solenoid switch which removes fluid pressure from the reverse piston and clutches.  The car now has forward movement in low gear and accelerates down the track.

If the car is moving backward any during the transbrake setting and staging process, it is likely due to one of the following problems:
 
  • Staging at an RPM that does not supply sufficient fluid volume -  OEM or weak pumps need additional RPMs to move fluid quickly and adequately to apply the reverse clutches.  Increasing your RPM before setting the transbrake is the first solution to try.
  • Low gear band not holding. 
    • The low gear band can be completely worn down which would prevent it from holding low gear
    • The band needs to be re-adjusted
    • The servo piston has failed, is leaking, or has broken a sealing ring
    • The band adjustment screw has broken or is bent
Check these areas if you are having transbrake trouble in your powerglide transmission.  These are simple fixes!  If you have any questions, contact our technical department @ 1-662-851-3213.

Norwalk Super Comp Triumph Vaults Bogacki to the Top of NHRA Lucas Oil Standings

 
 
 
Norwalk, OH: Sportsman racing veteran Luke Bogacki earned his 6th NHRA national event triumph and first at Summit Raceway Park when he drove his Motor City Hot Rod & Racing Expo backed American Race Cars dragster to the Super Comp victory at the Summit Racing Equipment NHRA Nationals.  With the victory, Bogacki moved into a commanding lead in the NHRA Lucas Oil Super Comp national points chase; he currently leads defending champion Alan Kenny by nearly 100 points.
Bogacki, who has earned a reputation as one of the best sportsman racers in the country thanks to his success in multiple classes and venues, earned the event title despite an admittedly mediocre performance.  Normally an excellent leaver, Luke posted reaction times varying from a competitive .016 (round two) to a very late .053 (round four), but was able to manufacture winning runs despite his lack of starting line efficiency.
“It wasn’t pretty, that’s for sure,” Bogacki laughed.  “I’m sure at some point I’ve won a race or two where I was never worse than .016 on the tree; I’m not sure I had ever won a race when I wasn’t better than .016 until today!  While I’m not happy with my driving, I’m certainly not ready to start the race over to see if I can improve my box score; there are no style points out here and wins are hard to come by.  I’ll take it any way that I can get it.”
Luke and partner Dave Szerlag recently announced that they will be promoting the inaugural Motor City Hot Rod & Racing Expo; Bogacki’s cars featured the expo logo throughout the event as part of the introductory announcement.  The Motor City Hot Rod & Racing Expo is a unique event that will feature exhibitors from throughout the motorsports industry, and is open to the public.  The inaugural show will take place March 22-23, 2014 at the Suburban Collection Showplace in Novi, MI, just minutes from Detroit, Motor City.  To learn more, visitwww.MotorCityRaceExpo.com.
Bogacki’s victory culminated a 5-week stretch of domination in the ultra-competitive Super Comp category.  Since the NHRA Division 3 Lucas Oil Drag Racing Series event in Chicago in early June, Bogacki has assembled a 21-2 record in the 8.90 category, highlighted by victories in Chicago and this weekend at Norwalk, along with a runner-up finish at Cordova Dragway Park in Cordova, IL. 
“It’s been an incredible few weeks,” expressed Bogacki.  “My car has just been great, it’s won almost in spite of the driver at times.  With my poor reaction times, I had to employ some smoke and mirrors this week to get the win, so I didn’t really let the car show its full potential; but this combination is really, really good right now.  Its consistency and a truckload of good fortune are the reasons for my recent success.”
 
 
 
Bogacki is quick to point out that a twin to his machine can be purchased with just a few phone calls.
“I don’t know if it’s a good thing or a bad thing, but the whole car is readily available, over the counter stuff.  It’s not like I’m sitting around in my shop brewing up some secret combination. The chassis is an American Race Cars base 240” dragster; and the motor is a 632 with BRODIX SR20 heads and a BRODIX aluminum block that can be purchased carb to pan at Huntsville Engine & Performance.  Everything else on the car can be ordered at JEGS.com.”
The Huntsville Engine 632 pushes Bogacki’s machine to the 8.90 index at speeds in excess of 180 miles per hour.  In addition to the BRODIX components Bogacki mentioned, the engine features an APD “throttle stop” carburetor and belt-drive fuel pump, Lucas Oil Products, K&N Filters, Hedman Hedders with Nitroplate coating, Wiseco pistons, a Milodon Oil Pan, J&J Engine Diaper, JESEL cam drive and rocker arms, and a Crane Camshaft and Lifters.  The motor burns Renegade 116+ Race Fuel and is slowed to the 8.90 index by a Dedenbear throttle stop controlled by a K&R Performance Engineering “Pro Cube” delay box timer.
Bogacki relies on Moser Engineering axles, brakes, and rear end components, an Ohlins Shock and Mickey Thompson Wheels and Tires.  He monitors air pressure thanks to an AirTek pressure monitor, and depends on a BTE Top Dragster transmission and torque converter.  Bogacki says that the Auto Meter Multi-Function Data Logger, which he uses to monitor and evaluate critical information including air/fuel mixture, engine & driveshaft RPM, G-force, and critical engine functions, is a huge key to his continued success.  Additional components include a B&M Pro Bandit shifter controlled by a Dixie electric shift solenoid, ISC Racer’s Tape, Nitrous Express components, and Earl’s hose and fittings.  Todd’s Extreme Paint designed and applied the car’s gorgeous paint job.
With his most recent win, Bogacki appears to be in dominant position atop the NHRA Super Comp standings.  The longtime racer, however, understands how quickly a championship season can turn and how many events remain on the 2013 schedule.  In 2010, he took the Super Comp lead with a clutch October LODRS victory, only to watch 4-time champion Gary Stinnett overtake him and earn the title at the final LODRS event of the season.  Last season, Bogacki fought hard all year but finished 3rd in both Super Comp and Super Gas.  He is yet to earn a NHRA world title.  With 591 points in early July, Bogacki acknowledges that 2013 promises his best opportunity to win the Lucas Oil Championship, but is quick to point out that it’s far from over.
“I’m right where I had hoped to be at this point,” he said.  “But I’m not going to kid myself.  591 points is a great total in July, but 591 isn’t going to win the championship.  I’ve still got a lot of work left to do.  My goal at the start of each season is to get to 650.  Even 650 doesn’t guarantee the championship, but if you reach that mark you’ve had a championship worthy season.  That total is realistic for me this year, but the key is to keep digging and get there.”
Luke Bogacki’s key supporters include the Motor City Hot Rod & Racing Expo, ThisIsBracketRacing.com, K&N Engineering, Tinsley Drilling and Company, C.A.R.S. Protection Plus, Advanced Product Design (APD), Product Development Group – makers of AirTek pressure monitoring systems and Flo-Fast fluid transfer systems, JEGS, Bill Taylor Enterprises (BTE), and Mickey Thompson Tires & Wheels.
