[Tigers] LAT bonnets and aston vanquish

[drmayf]

NACA ducts are boundary layer ducts. One of the features tha makes them 
work, and is hardly evr discussed, is the fact that at the rear the 
upper surface is an airfoil shape. That is to accelerate the air to 
increase efficiency.  People have tried them backwards thinking that if 
the work well th epointy end forward as an intake they shoul work well 
with the pointy end backwards. I don't believe these are very 
successful, but, I could be wrong.   The Sunbeam may get one for the 
turbo intake next year if speeds are not up to my goal this coming year. 
The inlet would fit flush with the hood and feed an air box with the 
turbo's air filter inside.
