Carb heat for the street

Since the early 1980's we have worked on several automotive fuel system research projects. From specialized idle circuit carburetor research back in the electronic "feedback" carb era, to road race and street performance carburetor fuel systems. A new aftermarket product, the "Carb Heat for the Street" finally, and elegantly solves the old carb ice problem on northern street machines. If you drive your carbureted street machine in temperatures below 50 degrees in places like Washington State, you know what happens. You have that nice aluminum intake manifold, no heat riser, headers with no heat tubes, and a big carb sucking nice cold wet air, and carb ice turns your car into a coughing no idle pig.

We have a solution! A aluminum spacer beneath the carb, with a small water jacket. The heater hose is run into the spacer, and out the back to the heater core. The engine compartment is kept neat and clean with this simple setup. Our test car, running a 350 Chevy with a Victor air space intake and no heat riser, has performed flawlessly even in the worst fog and cold, all the while breathing 100% cold air via cowl induction. 

Carb spacers are available in 1" and 2" open hole or with center dividers. They come with NPT  water ports, and a vacuum port.  Please email for details!


Wideband o2 sensors

Whoo-hoo! Wideband o2 sensor prices are within reach of almost everyone today. We are building  wideband sensor electronics that anyone can afford. No frills, it uses a standard wide band sensor signal, and emulates the stock narrow band sensor output. This allows you to replace your narrow band sensor with a wide band unit, and keep the cars computer happy. Then with a "real" air/fuel sensor signal, the inexpensive narrowband display turns into real fuel system tuning tool. If you run any fuel injection system, you know how empowering it is to know the exact air/fuel ratio! Don't confuse our system with the typical cheap narrowband setups that just flash worthless colored lights. We turn their worthless narrowband displays into real time wideband displays, something to cheer about! Please email for details!  You can learn more by visiting our web site and learning how this tuning tool is used on formula race cars running Lucas petrol injection systems, and for tuning our "street project" car, also running a Lucas system.


Lucas petrol injection

Our current research involves Lucas petrol injection, and wide band sensor tuning. Lucas petrol injection dominated road racing from 1959 until the early 1980's. The vast majority of Formula 1 cars, and in some years all the F1 cars ran the Lucas mechanical system. By 1980 Lucas petrol injection had won 20 F1 World Championships. Almost all the Can-Am and Formula 5000 race cars were Lucas injected. Since 1972 Lucas was used on offshore race boats, and has won 9 out of 10 offshore races. In Europe, Triumph, Maserati, and Ferrari all used Lucas injection. Back then you needed a RAC license to buy a Lucas racing setup, so almost none ever made it too the street! Well, we are changing that by doing a Lucas small block Chevy street project car, and putting it all on a Lucas info web site! Visit us in the garage at: www.lucasinjection.com
