DAYTONA PROTOTYPE
An interesting race car AVR Performance has been involved with recently is Glenn Smiths Crawford DP03 Porsche twin turbo Daytona Prototype.
A Daytona Prototype is a type of sports prototype racing car developed specifically for the Grand American Road Racing Association's Rolex Sports Car Series as their top class of car. They are named after the main Rolex Sports Car Series event, the Rolex 24 at Daytona.
There is a Kiwi connection with Crawford Racecars in that company founder Max Crawford is a expat New Zealander. In the early 1970’s he built and raced cars in the OSCA series before heading on to the States.
The cars that run in the Rolex Sports car series must run a non turbo production based engine (BMW, Ford, Toyota/Lexus, Porsche V8’s along with Porsche flat 6 cylinders & Honda V6’s are used). As Glen’s car no longer runs in that series it has been fitted with a Porsche 996 based 3.6L flat 6 with twin turbos which provides plenty of giddy-up at moderate boost.
The engine is mid mounted to an Xtrac paddle shifted 6-speed sequential transaxle. Lots of down force, huge Brembo brakes, optimum weight distribution and a lot of rubber all combine to make this a very formidable package.
The car was built with just about every box that Motec has made including M880 ECU, ACL logger, VIM's (versatile input modules), telemetry, CDI, Dash display and E816 input/output expander.
The twin turbo conversion was done in the States, however it was not track tested before Glenn purchased the car so there was still a lot of teething problems & sorting to be done initially. Glenn has enlisted Maurice Ebbett of Ebbett Motorsport in Palmerston North to engineer the car. AVR Performance has been involved with getting the Motec boxes to talk to each other and setting up the electronic systems along with dyno tuning.
Glenn has been running the car at Manfeild in their winter series and is coming to grips with it's potential picking up the Manfeild tin top/GT outright lap record along the way.
This is in preparation for the up coming GTRNZ GT1 race series coming up this summer. If you are any where near a race track this summer this series is a must see. Glenn will be joined by the likes of Carl Hansen (TVR Tuscon), Cameron Jones (RX666 Camaro triple rotor turbo) and Nick Chester (V8 supercar on steroids). So if you want to see the fastest things with roofs in New Zealand these cars are them.
