Ask Jay: Downforce, Gas & Licensing
July 29, 2010 12:00 AM
Jay pulls out the Duesenberg SJ to talk about modern gas and old school engines, made when gas was gassier. Other viewer questions include licensing unique vehicles, active downforce in the McLaren F1, and the availability of diesel cars in the U.S.
What kind of gasoline do you use in your older engines? My 1945 Willys refuses to run on gasoline that has any ethanol in it at all, even the 10% blended stuff they have now.
Bill Shoffner asks:
Why can't we buy American cars with diesel engines? They're available in American-made trucks so why not cars, too?
How do you get your more unique stuff like the Tank Car or EcoJet licensed in California, with all of CARB's strict emissions regulations?
Ryan Lannom asks:
I've heard that the McLaren F1 has some kind of active downforce system that ensures negative air pressure under the car. Can you show us where it is and how it works?
