DIY: Fang Vents: Forced fresh air to your airbox

TreeSemdyZee · 05-24-2010, 11:42 PM

I hate to be paranoid, but from someone who lost his 350 to flood waters last year, I'm slightly leary of this setup. I had one of the common bumper inlets on my car with a tube running to the airbox. I know that is much more of a straight line than this, but there is a serious vacuum effect in the intake that needs to be considered.
I may be completely off-base, but I'm slightly paranoid if you know what I mean. Just my

Modshack,

I had the mod done last week while installing the oil cooler while the bumper was off. Since I tracked the car for a day with both mods, i couldn't measure the "gains" but i am pretty sure that your DIY helped to reduce the engine bay at WOT speed. Great addition!

Question for those who did this mod:

- I notice some "strange" outside temp on the console (showing more than the actual outside temp was). Did anyone notice this or did my mechanic damaged the outside air temp sensor

Phil.

Paranoid people should not mod......

(or at least avoid driving through deep water)

My experiments on another similar design (sealed) on another car showed that the flow up dual 2.5" hoses was enough to pretty much eliminate any restriction at the airbox outlet, and actually show some positive pressure on a Magnehelic gauge..

Very nice, great work !

What about it? Forced outside ambient air is good for either.

Well I wasn't sure if you'd recommend a filter behind these ducts in that pic I posted if say we had dual SRI. I know these being much more expensive then your DIY but I figured for the paranoid these might help them sleep better?.?.

My Modshack designed intake was essentially an SRI. No need for any additional filters or anything that would slow or restrict airflow. Converted back to stock, left the vents in, before I sold the car and still worked just fine..
