[DeTomaso] Cold air intake pickup locations

[Tomas Gunnarsson]

I can answer #2: No, the air in that area is only a few degrees above
ambient when the car is moving according to my measurements. I have two
90 mm hoses arranged like you describe. No scoop, they end pointing
straight down with no protrusion below the chassis. I don't pick up a
lot of debris either.

Collective, 

I am considering a dual snorkel air cleaner with cold air ducts running 
down either side of the firewall just forward of the engine. The
passenger 
side could be routed more outbound than the driver side due to the fuel 
tank. I live in a hot region, so any non-heated air would be of benefit.
Questions: 
1) Is the underneath of the car a low pressure area that would deter
from 
airflow? 
2) Is there significant heat from the radiator and coolant tubes on the 
driver side to negate any benefit? 
3) Would the added drag of a longer duct significantly reduce air flow? 

Thoughts? Rationale?
