[DeTomaso] Cold air inlet idea

[Wayne Boian]

Good information, thanks for posting. Is there a picture of your car somewhere so I can see what it looks like with the side scoops?



Thanks

I have been using a sealed air box that is fed from small side scoops 
that replaced the rear side windows since 2013. A couple of years ago 
one of the members on this forum sent me a digital manometer and I did 
some testing on this system. From 10 mph up to 120 mph there was an 
increase in air pressure inside of the air box. It wasn't a tremendous 
amount, but is was definitely a positive pressure. I also attached some 
yarn to one of the side scoops and by just increasing the engine RPM, 
the yarn was pulled into the scoop. My own tests which were done using 
my on board EFI system monitor showed that there was a 40 to 45 degree 
temperature decrease in the engine inlet air temperature with the air 
box hoses connected vs them being disconnected. The idea of pulling air 
into the engine via the side gills will work, but you have to have the 
system sealed because of the air that is being forced up into the engine 
compartment from the ground underneath the car. If anyone is interested 
in looking at my system and testing it themselves, just contact me at 
the 2020 Fun Rally.
