What Defined Autoworks is, and what we do-
History-
Defined Autoworks is a company recently constructed and created to meet the exacting criteria of customers today. With the fast and furious age dying out, many in the car industry say that business is slowing down. As the sheer volume of these so called "enthusiasts" have indeed died down, the REAL car guys are bigger than ever. This type of customer (yes, this is you) has been around the block a few times, has seen lots of different stuff, and desires that "next level" of true hardcore parts and performance. Enter Defined Autoworks. We are merely a small shop, being handed down as a family business of over 30 years. The original owner, Ken Carswell, was at the forefront of rotary vehicles. Being one of the very few who was actually trained by the Mazda program to rebuild the rotary engine. Starting this business in 1976, his knowledge and rebuild skills were later passed down to Logan Carswell (GtoRx7). After 9 years of building rotary engines, and putting together many unique cars, Logan decided it was time to put some performance into a proven business. With the help of skilled driver/mechanic and good friend, Peter Chhuom (S14.3BRE), a branch was formed to serve the die-hard community. And we plan on continuing to serve this community for many years to come.
Services-
As a new company, more new and high quality products will be coming out as time goes on. At our shop here in Ohio, we can perform any type of custom work, or even just simple installations. Being very well versed in putting together full race rotary engines, to basic rebuilds. Even complete one-off stainless exhaust systems, intake manifolds, engine swaps, race suspension setup, stand-alone installs, and full dyno tuning are just some of what can be done in-house. We always love to take on a challenge, and will not rest until the problems are solved. We enjoy coming to work each day, and take great pride in our customer service, and support.

Size does matter, bigger is not necessarily better.
Therefore on an NA engine, scavenging and eliminating back pulse on the intake side becomes important in increasing HP and Torque at lower speeds. My early 12a aspirated engines would develop as much as 40 HP more in the 3500 to 7500 rpm range than Rotary Engineering and Racing Beat engines. Yes, they developed more HP at the top end, between 7500 to 8500 range, (about 5-10 HP), but on a road course with the additional torque and less shifting you could get better lap times and a more durable engine. As a street engine, you could put it in 5th gear at 1500 rpm and not get any bucking or bogging with proper throttle control.
That is why I used 1 5/8", 100+" primaries on the 12a and no bigger than 1 3/4", 100" primaries on the 13b. They worked great. Most of these engines ran above 5,000 feet elevation in Colorado and performed great at 10,000 feet. We took this approach and made several engines for experimental aircraft, which worked well.
Just food for thought. At 70 years of age, maybe some of the younger generation can take advantage of real experience.
