1906 Adams-Farwell Rotary Engine

Posted on by

The National Automobile Museum in Reno Nevada brought their 1906 Adams-Farwell Series 6 touring car to Pebble Beach last year. It’s the last car of it’s kind and it has the only working Adams-Farwell air-cooled 5 cylinder rotary piston engine in existence. Rotary piston engine you say? The crankcase with the 5 cylinders rotates around a stationary crankshaft in the center of the engine. The layout used centrifugal force to distribute fuel and scavenge exhaust gases while providing exceptional air cooling. I guess this is technically a rotary radial engine which is rad.

Cosworth Turbo V6 F1 Engine

Posted on by

Check out this vintage documentary of Cosworth building their first turbo V6 engine for the Beatrice Haas Lola F1 team in 1986. They came up with some interesting engineering solutions for dealing with the forces that the internal components see at high rpm with forced induction. There’s definitely some assembly steps that you won’t see on any road going mass produced engine.

GM Announces the LT1 – Motor Trend

Link

Big news out of General Motors today with the announcement of the new LT1 V8 that will be replacing the venerable LSx family of engines in the next Corvette. The 6.2 liter V8 makes 450 horsepower and 450 ft-lbs of torque and is projected to get 26 mpg in the C7 thanks to cylinder deactivation and direct injection. Interestingly enough, GM was able to improve the gas mileage by increasing the displacement, not reducing it. The larger 6.2 liter engine means a 3.1 liter V4 when the engine is running in cylinder deactivation mode. The V4 makes enough power that it can be used more often in the engine’s duty cycle which reduced the overall consumption of the engine. V8 power only when you need it. Very clever. Head over to Motor Trend’s article to read up on all of the details with pictures and dyno videos of the new engine.

Stinger 609 – Conley Precision Engines

Posted on by

You are probably looking at this picture of the Stinger 609 supercharged V8 by Conley Precision Engines trying to figure out what’s so special about it. It will be tough to see because there isn’t a scale reference for the engine’s size. The “609” in the engine’s name stands for 6.09 cubic inches which translates to a little less than 100 cubic centimeters. To put everything in perspective, the Stinger 609 is a little over 14 inches long and 10 inches tall with the supercharger and dual carburetors. Other features include a dry sump oiling system, full ignition system and an integrated electric starter. The naturally aspirated version makes 5.5 hp at 9500 rpm and the supercharger bumps the power figure to 7 hp. Pricing is $5700 for the NA version and $7400 for the supercharged Stinger. Check out the dyno stand run below:
