<VV> Airflow, Cooling Rear engine 266 V8 pics

[Jim Briggs]

Thanks for all the great input on my airflow question! 

     I have uploaded a number of pics to the fastvair site of the modifications I made 

to my Corsa during construction. I thought I had overengineered the cooling 
system but I am experiencing conditions very much like Terry Kalp described.
It will idle forever at 160 degrees but temp will gradually climb at hiway speeds. 
Ambient temps in my area can hit 100 plus for extended periods in the summer
so I continue to tweek in hopes of finding a "magic pill" without moving the radiator 
to the front. I am pulling air from under the car with primary diverters and a main
air dam. I have modified the rear package tray area and added to the grill opening area
behind the rear window to help airflow. You can view these mods in Fastvair photos under

266 Cooling. I am currently trying a quick and ugly airfoil in front of the rear air grill

at the base of the rea window to try to create negative pressure there to help with airflow.

At 60mph this setup seems to be holding in the 200-205 degree range for my 16

 mile "test track circuit" on a 100degree day. 

>From what I have garnered from you all so far, I will NOT try to reverse my current air 

flow scheme. I will keep it from bottom to top. Beyond that, I am still grasping for 

improvement.

 

Take a look at the pics and see what you think.

 

Thanks for the help!
