From my old auto tap data, there was an easy 20 degree difference from the KKM to the CAI. With a battery relocation, I was looking at another 20 degrees cooler than the CAI by itself and got to within a few degrees of ambient temps on an 80+ degree day.

True, at a standstill, the CAI would injest warmer air. Once the car begins to move though, the CAI *clears* itself of that warmer air much faster as shown in Autotap scans of IAT and MPH vs. time.

Dyno results would be a waste of time with this type of CAI as it makes it's gains with increased air movement from the car moving. Dyno runs are made with the hood open and a slow moving fan blowing at the front of the car = worthless.

Case in point:

'99 CEG National meet in K.C.

Early SE with KKM and SVT Exhaust dynoed at 159HP. I can't remember the guy's name, seems like it was Randy, or Ross or something like that. Champagne color 5 speed with E0 rims.

My SE with CAI, KKM filter, Eram, and SVT TB dynoed at 142HP

Later that night at KCIR, in 90+ degree heat and 95% humidity, he ran a 16.4 at 86MPH, I ran a 15.9 at 89MPH. The E.T. can easily be attributed to the driver, but 3MPH was a big difference in trap speed. I even beat quite a few SVT's that night. (Slow times were due to it being so hot and sticky) Think it was the Eram?

Here's the proof that the CAI gains don't run up on the dyno. Randy Sauer was his name. I was wrong about the other SE being 159 though, it was 150HP and I was at 142HP. Please note, that was with the stocker 2.5L in there, not the 3L.

I don't have the 4 and a half year old time slips anymore. Sorry. Gains that were four years old are tried and true to me. I won the fastest SE award from KKM and I beat several SVT's doing it. Neener neener.

I looked at ALL the sheets in that workbook and I am having a hard time picking out which one you are specifically talking about. A lot of interesting info though.

This is a good design, even though I wouldn't buy one from this site:

Brad could you build one like this, people would buy! Your a celebrity here

Now I know there isn't a heatshield in this pictures as it was taken in full winter glory just after some mods but...

You can see the nice cold air duct from a scoop in the front airdam and I can guarantee that my IAT numbers are at ambient when the car is moving.
Tranny heat soak, engine heat soak, radiator heat soak or fans on it makes no difference because the heatshield (when installed) blocks off the entire area above the fender.


Also straight piping is better for NA airflow and creates less turbulence (under pressure it's a fairly moot point)


I'll post a better picture once the plexiglass heatshield is back on (you can see the new 3" intake pipe too) and the engine bay is cleaned up.
Looks almost stock eh???

You did "relocate" the battery though....
Granted, the BNM CAI isn't the "BEST" option, but would it be recommended for someone who does not want to "relocate" the battery and keep it a simple transfer between the stock setup and back to the CAI due to smog testing, while still making gains over the "KKM location" setup? I am really torn between this idea now....I want one because it seems extremely simple and would seem to work better, but I don't want to waste money, especially $100....

Where can we get that information on CFM draw for an engine? It's probably some equation you know of that relates horsepower vs. engine displacement but I've never seen anything like that.
I ordered a chip through Keyser and would like to find the correct air filter for my application.

(Sorry, not trying to hijack!!)

I had something similar before going to a CAI pipe. The IAT temp samples did get back to near ambient with a dryer hose in the airdam, but the CAI got back to ambient much quicker and at a lower speed than your pictured location. Once the battery was relocated and my CAI was made larger (with the 12" long filter), the IAT cleared even quicker.

Do you have IAT readings that you're going by, or is this more theory? EDIT: Duh, nevermind. At what speed and time are your IAT temps returning to near ambient is what I meant to ask...

I'll agree, my BNM CAI isn't the best way offered because most people don't want to pay for the best way. People want 100 horsepower for $10. This is a step closer in that direction compared to the old South County CAI's...

Demon ... what did you use to paint your coolant tank. It looks WAAAAY better that way!
Also - how do you check the level of coolant when it's painted like that?
