Homemade Ram-Air Install Pics added

So...just got done fabricating and installing my homemade ram-air kit. I made a new radiator flow plate (black plastic plate under radiator brace) out of 22 gauge sheetmetal. It was an exact fit and installed in all of the stock spots. I then bought a rectangular funnel made out of thin galvanized steel (almost feels like tin), a 4" to 3" adapter, 3" flex hose for intake piping, and of course worn clamps. Got everything bolted up (funnel bolts directly to flow plate and flex hose bends in stock spots, just a few inches longer), and took it out for a test drive. I had a 180 lb. passenger this time as compared to the runs without the ram-air. Here are my results-All runs are dead stop blasts to 90mph and back to 0mph.

No Ram-Air=(First Run)Intake Box Temp-102
Engine Temp (taken at valve cover)-184
Header Temp-345
(Second Run)Intake Box Temp-98
Engine Temp-187
Header Temp-372
(Third Run)Intake Box Temp-105
Engine Temp-186
Header Temp-378
With Ram-Air Installed=(First Run)Intake Box Temp-74
Engine Temp-168
Header Temp-314
(Secong Run)Intake Box Temp-76
Engine Temp-168
Header Temp-333
(Third Run)Intake Box Temp-76
Engine Temp-178
Header Temp-353
So as you all can see, the ram-air definetly dropped the temperature, sometimes drastically, all around, and it also stabilized alot more. It feels like there is more mid-range power, take that for what it is. But all in all a pretty good mod. Good alternative to a cold air kit, in my opinion, and cheaper. Let me know what you all think. I can e-mail pics if wanted.

I'd love to see some pics.

And what did you measure the temp with?

I did a VERY similar test with a short ram, and real cai, and my ram air with the svt airbox and a K&N. My results were very similar, here is a couple pics:


It uses a 3" tube that goes up to the rear part of the svt snorkle which just happens to about 3" and used 3" aluminum ducting (rigid type)

According to most reliable sources, a 10 degree reduction in air intake temperature results in a 1% increase in hp. So, the average of all your runs means an average intake temperature decrease of 26.33 which should equate to a 2.63% increase in power. So, on a typical, unmodified SVT, with a rated hp of 170, that should mean a 4.47 hp increase. Interesting.

Mike supplied me with one of his scoops and it works really well - I also have a Volant air box from a regular zetec modified to fit. I had to do some shaving but it all works very nicely especially since the top of the volant forms a nice seal against the hood.

Please email me pics, I PM'd my email address. It would help to just upload them to a www.photobucket.com account and post them in the thread. It's free and easy.
