Here's where I got mine and some info from Team Novak:
Make the Move to Modified Racing
Novak's modified racing 540-size brushless motors ofFer a complete line-up from 4.5-turn through 8.5-turn. The Vulcan Mod motors are the most current 540 motor series from Novak developed to offer a balanced, smooth delivery of amazing power and speed. Vulcan Mod motors take the proven, high-RPM stator blank, and use new combinations of Novak's pure copper Red Wire to offer racers a proven and efficient modified motor platform.
Vented endbells provide maximum airflow and cooling. Novak engineers have fine-tuned the stator, the winding, and wire specifications. This new wire sizing and high-RPM stator hae proven to be a perfect blend of smooth easy-to-drive power. Club racers, bashers, and factory drivers comment on how smooth the motor power is without feeling flat or soft.
A motor is nothing without a rotor. Novak motor rotors are magnetized and tested right under Novak's own roof in California. This means our rotors are the most consistent and reliable available. Vulcan Mod motors work with the entire line of tuning rotors, but include the king of efficiency, the 12.3mm Neodymium rotor. This rotor has proven time and time again to be the perfect balance of power and RPM efficiency. If your conditions require a different power band, Novak offers a full line of tuning rotors to suit your racing needs.
Five Modified Motors Available
Vulcan Mod motors are available from 4.5-turn to 8.5-turn:
4.5T - 6.5T: For 2WD SCT, 4WD Modified Buggy, 2WD Stadium Truck and Touring applications, and other large-track usage
7.5T: For 2WD SCT, 2WD Buggy, 2WD Stadium Truck, and for various indoor or medium-sized tracks
8.5T: For smaller tracks, situations requiring maximum runtime, or first-time modified racers
Vulcan Advantage
Novak has been building sensored racing motors since 2002—longer than any other brushless motor manufacturer. The Vulcan is bred from these years of experience, uses high-quality materials, and has pride of craftsmanship.
High Quality Steel: Novak uses the highest quality steel in the stators, and has developed a proven stator shape. Used to win countless races over the years, and proven to be one of the most efficient designs on the market. Vulcan stators have been updated slightly to increase the basic RPM range. Since the stators are interchangeable, the Vulcan Mod can easily be converted to a Vulcan Spec or a Vulcan Outlaw motor.
Red Wire: The wire is the coil of the motor, and Novak uses 100% made in the USA, 99.9% copper wire. The coveted red wire has been the talk of the racing world, and is used in each Vulcan motor.
Larger Vents: The Vulcan utilizes an all-new, front endbell with larger vents and a one-piece front can to ensure maximum airflow and proper bearing alignment. The timing assembly has also been improved to allow easy, consistent, and a wide adjustment range. An easier to service motor means you are back on the track faster!
Tuning Rotors: Compatible with all Novak 540-size tuning rotors.
Completely Rebuildable Design
The new Novak Vulcan motors have the same race-friendly, Ballistic brushless motor design and is completely rebuildable. At the track, service and repairs are a snap, allowing you to get back to turning laps right away. Replaceable sensor harness, replacement tuning rotors, replaceable sensor board, replaceable stator, replaceable end bells and bearings- you name it. If the motor has it, you can pick up the spare part and be back in action in no time!
