1961 Lotus Elven 23B Race Car

Description for Lotus Elven 23B 1961

The Lotus Eleven model had been hugely successful, in both sales and in races. This lightweight, streamlined, low-slung, two-seat "sports racer" tremendously extended Lotus' reputation. However, the Eleven had been launched at the beginning of a period of especially rapid technical development. Soon, tough competitors joined the fight. The next few Lotus sports racers were less notable, until the new Lotus "23" model arrived in 1962 and brought Lotus right back to the top of the class. The Lotus 23 was mainly designed for engines up to 1.3 liters displacement. The Lotus 23B variant, featured here, is similar except for a heavier duty frame to accomodate engines up to 1.6 liters.Lotus 23B serial number 23-S-61 was originally delivered to Ian Phillips of England, painted white with blue stripes. It had been specified with a 1600cc Twin Cam engine and a Hewland 5-speed transmission. It was soon purchased and moved to the United States, where Ed Cicotte raced it actively in Sports Car Club of America's (SCCA's) Central Division throughout the 1960s and 70s. Cicotte changed engines at least twice. For a time, he raced it with a 1.5L Coventry Climax V8 with Colotti transmission. He later fitted a 2.0L BMW engine.
Ed Cicotte sold the car to Ed Dickenson in the 1970s. Dickenson raced the car for awhile with the BMW engine, then began converting the car back to Lotus Twin Cam power in the mid-1980s but didn't complete the project. Dickenson died in 2002, and Don Munuz purchased the unassembled car.
In 2004, Don Munoz completed an extensive restoration of this racecar to original 23B specifications. As shown below, it has been returned to its original configuration with Lotus 1600 Twin-Cam engine. Don has subsequently raced it in three to four Sportcar Vintage Racing Association (SVRA) events per year, before deciding to offer it for sale in 2010 when it was bought by Donnybrooke Motorsports in Spring Park, MN. It has been raced and maintained by Donnybrooke since. It has most recently had a transmitter radio installed for track day communication and the suspension has been rebuilt. Also, the harness' have been updated to comply with track specifications.
