Lowering Intake Temperatures Part 2

OK, so the first part of the segment didn't really do anything other than take current measurements and lay down some background. Part of that is due to a lack of funds and another part due to lack of time. It might be a while before I can actually try these next methods, but when I do, I'll post the results.

Header Wrap: I don't think wrapping the headers will really help all that much since the airflow under the car most likely provides adequate cooling. What I would like to wrap is the up pipe going to the turbo, the turbo itself and the down pipe. This should drop the under hood temperatures and therefore promote lower intake temperatures. Other benefits are cooler wires that run close to the turbo and a cooler compressor side of the turbo. 

Hood Scoop: The hood scoop is mostly self explanatory. It will be located just right of center to feed the SAAB 900 intercooler that is on the car. This should drop under hood temperatures drastically. More importantly it will help cool the intercooler. 

Intercooler fan: During stop and go style driving the intercooler becomes more of an inter heater trapping rising heat from the motor. All of the previous methods should help keep this to a minimum, but a fan should eliminate it all together. The two locations for the fan would be on the top of the intercooler and the bottom of the intercooler. I would think locating the fan at the bottom would be more efficient during track use. I'll have to run some tests to know for sure. 

Phenolic Intake Spacers: More on this is covered with it's own write up. 

Non heated throttle body: A quick adjustment to the throttle body to eliminate the water lines that go through it. On the down side, this can cause the butterfly to freeze. On the up side, this will keep the throttle body from heating the incoming air. More on this with it's own write up.
