OVERVIEW
Location: Cincinnati, OH, USA
About Me: I'm a married 40 year old father of two and a Regional Sales Manager for a global Security company. I've been a shade tree mechanic since I built my first go kart at age 12 and have been keeping my hands greasy on cars ever since. Although I'm not an Electrical Engineer or Programmer by trade (luckily, my father is!), I've been fortunate to develop a technical apptitude over the years working on small projects in these areas. A good friend of mine exposed me to his MegaSquirt project two years ago and I instantly knew I HAD to convert my car to EFI! I researched nearly every possible EFI system for my project and VEMS was the clear choice for flexibility, capability and certainly value. Nothing really compares short of a high end MOTEC!
Current Project: 1969 Chevrolet Camaro RS SS Convertible, "Pro Touring" Conversion with EFI
Engine Specifications:
- 417 CID small block Chevrolet V-8 (4.155 bore, 3.875 stroke), normally asperated
- 513 hp at 5,400 RPM and 539 lb ft torque at 4,600 RPM. (These numbers were measured on the engine dyno using Edelbrock RPM Airgap dual plane manifold and Holley 830 HP carb. This combination started making 430 lb ft of torque at 1,800 RPM, the lowest RPM during the pull, and made over 500 lb ft from 3,300 RPM to 5,400 RPM! The combination made for a great street engine but EFI will only make it better!)
