Its been a long few weeks for Apex’s Tim Whitteridge, point-man for the Singer Porsche project.  He’s been re-engineering the 25 year old Porsche 964 electrical system to provide modern levels of functionality and reliability – a task which involves a lot of reverse-engineering, detective work and deep technical understanding.  Together with Apex’s master wiring ace Alex, parts sourcing guru DJ and eager-to-help-out-in-any-way newest engineer Kelsey, our team has been working on on this project for months, and are excited to see it come to fruition!

Original Singer 911

The first Singer 911 we worked on last year

Apex started with Singer last year, providing tuning services for their 1st generation cars.  With the Rob Dickinson designed body & interior they had an absolutely beautiful looking car; now Singer was turning their attention toward improving the performance and drivability of the package.  First, an introduction was made to our friends at Cosworth, and before long they were a partner in building the engines.  With the newly minted Singer & Cosworth relationship in place, putting Apex in the role of their electronics provider was a natural fit.  Apex worked with Cosworth engineers on their dyno to develop calibrations for the 3.9L Porsche flat-6.  Along with the move to Cosworth, Singer switched to Pectel engine management systems with a mix of AEM sensor components, all provided by, setup and tuned by Apex Speed Technology.

The 2nd generation Singer Porsche are Porsche 964-based, which meant significant differences in almost every respect.  The first step was to get the Cosworth assembled-motor on the dyno, which involved building a dyno harness and spec’ing a sensor package.   Our friends at AEM were happy to provide their stainless-steel pressure sensors for Fuel, Manifold and Barometric pressure, while the laboratory-grade NTK Lambda sensors came from Pectel.  Over the course of several days, we worked with Eric Hsu, Tyler Hara & Lyon Kaplansky from Cosworth along with Jae Lee from Mirage International to evaluate different intake hardware, camshafts and engine calibrations.

The next step was to redesign the late 80’s engineered wiring harness to suit a 21st century electronics package.  This involved building a full millitary-style custom wiring harness for the engine, lighting sub-assemblies and other details such as the adjustable wing and Becker entertainment system.  These were fitted to blend into the car, with black heat shrunk lengths nearly invisible when fully assembled.  There were many tricks involved with replacing the old exhaust heater boxes with a gasoline-fired heater while using the stock climate controls, integrating idle-air control with the individual throttle body intake and maximizing the performance of the knock control system.

The introduction of the Singer Porsche on November 16th, 2011 in conjunction with the LA Auto show was a brilliant success, with international media, world-renowned designers, collectors and prospective buyers all in attendance.  We are looking forward to more cars, each with their own little tweaks as we settle down into a production role.  Many thanks to the Singer & Apex teams for putting in the hours, hard work and dedication required to make this project a success!
