Mark Miller from Texanne Racing in Western Australia is a both a Sprintcar Driver and Sprintcar owner. He has competed in the 350 Limited Sprintcar category over the last few years and is now signing up for the new 360 CI Sprintcar series in WA – “The Chamberlain Auto Electrics 360 Power Series”.
This season Mark has teamed up with Ian Woods and he may even have a shot at a couple of 410 CI events. Woodsy will be spannering Mark’s car and providing valuable coaching.
Recently Mark invited Torque Tube Media to attend a Personal Chassis Fit-Out Session at Geoff Murphy’s Maddington workshop where Geoff creates the renowned “Murphy” Sprintcar, Speedcar and F500 chassis’s.
Mark is a pretty tall guy at 6 foot 11 inches and has found it difficult to get a traditional Tall Boy chassis to suit his requirements ……. So enter Geoff Murphy and the custom built ETB (Extreme Tall Boy).
In the same way that a tailor will measure you up for a suit, Geoff Murphy will measure you up for a custom chassis that is precisely engineered around your personal stature with an ultimate aim of the best possible safety, ergonomics and comfort – something that Mark has grappled with for years by using frames that came close, but at the end of the day didn’t quite cut it.
The new Extreme Tall Boy chassis is 6 inches taller than a standard frame. Some of the key differences in the custom frame are extra bars to provide additional strength, a raised seat and raised steering box to provide optimum ergonomics and a unique front header bar to maximise clearance to the front of the helmet. The chassis owes its pedigree to the standard 40/47 Murphy, however 2 inches were added to the rear to give more cab room, and another 2 inches added to the front to maintain balance. So what has resulted is a custom 42/49 inch car.
Mark went on to say “The reason for the custom chassis was mainly safety driven because of the head clearance rules. Working with Geoff Murphy we have been able to build the car around my body to give truckloads of head clearance, all achieved without an add-on Halo. The comfort is second to none for me. My legs feel like they are in the right spot and the steering has been placed for optimum ergonomics as well. The car is so comfortable compared to what I have had in the past.”
The chassis is all but finished. It only needs a couple of bar refinements and locating brackets for the quick change and top wing adjuster. Then Mark is ready to take delivery, build it up and go racing !
Torque Tube Media wishes Mark Miller and Texanne Racing a successful season ahead and we will all look on with interest to see how the new car shapes up. Also a big thank you to Mark and Geoff Murphy for allowing Torque Tube Media to attend the fit-out.

PS: While at Geoff Murphy’s Workshop I had a bit of a chat with the owner. Geoff is a very talented chassis constructor and in past years has had involvement with people like Bob Trostle (The Father of the Sprintcar) and a very Young Steve Kinser. We will be doing a special feature on Geoff and his products in the coming weeks on torquetube.com.au
