So the new Impalla that chevy has released has a option for a 330 HP V8 with 28 highway fuel consumption.
Thats amazing. Just amazing. I wonder how far fuel efficency can be pushed? |

Ferrari uses something like a V-tec engine. V-TEC stands for Variable Valve Timing and Lift Electronic Control. The Vtec solenoid pumps fluid into a small pinion, which engages a different lifter which makes 2 valves work off of 1 cam lobe instead of each valve having it's own lobe..In essense in a DOHC(Dual Overhead Cam) car you get the benefits of 4 camshafts.. 2 different intake cams and 2 different exhaust cams (due to the profile change.
Is this what you were thinking about Jim? (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) |
