We are trying to make a set of EFI Throttle Bodies that fit the concept of a classic car and look a bit like a High Butterfly RSR system.
We realise PMO make system that looks like the Weber and Borla make a system which is Retro but wanted to 'row our own boat'.
The Jenvey system doesn't do the job in quite the manner we wanted and although I am sure it works well is only a set of Universal Throttle Bodies, manifolds and linkages. There is still quite a bit of engineering needed.
The basic throttle body we can make between 42mm ID and 46mm ID in terms of bore diameter.
300BHP engines on carbs typically use a 46 IDA with a 36 or 38mm choke so airflow shouldn't be an issue.
We have incorporated a balancing system and vacuum ports for fast idle and load sensing.
Injectors are Bosch Motorsport EV16 which are good quality and available in a decent range of capacities.
The system also uses individual fuel hoses rather than a singe rail which is a cosmetic change to aid the retro appearance.
We have two systems in production.
This first is to fit to a Carrera 3 engine which will be used around town and will try to emulate the drivability of a modern car with economy improvements compared to carbs.
The second system will be installed on an RS replica with 10.5:1 compression, GE60 Cams and Twin Plug Heads.
We are also making a 'billet' distributor with an internal trigger wheel which will sense crank and cam position so we can sequentially trigger a DTA engine management system and maintain a retro appearance by fitting a Dizzy with a Bosch 12 plug cap.
