Quit your whining. I never got around to it, and the damn engine has changed too much. New sig pic when the CAI is in it'* final form When I get the final version of the CAI done and it gets a bit warmer outside, I'll run the same tests again. If I can hold the IAT and SC/TB temps to within 5-10 of ambient air temps, I'll be a happy camper come summer.

Noticeable improvement in high rpm'*. Accelleration from 75-100 is obviously quicker and snappier.

Great job Bill and nice write up
The WillJet idea is a great one and you have inspired my creative zest to find something for the newer bonnies
Glad to see the co-pilot used the green' pen for official stats

Katie had a blast doing this. And being a 'remote' part of the club. My only advice for moving forward on other cars is possibly trying to find a higher mounting location. Mine is JUST at the limit for me. I'll see how they hold up long-term (this is why I used beefy exhaust tips, btw).

You know, I sorta get the feeling like a couple people think it'* an increased positive pressure under the hood that is solely increasing the HP. Although this makes a difference, much HP gain is also due to the cooler air and running temps of the engine. Cooler air expands more than warmer air when driven to the same temp (during ignition), hence more HP as well!

That, my friend, was the goal. At least on that side. One scoop provides a constant source of cold ambient air for the filter to draw.....displacing some engine bay heat that may migrate into the CAI.

The other side is to cool the SC inlet and TB, to further prevent heat from getting to the intake charge, as well as alleviate some heat for mechanical longevity of the SC itself.

Here'* just a thought I was sorta toying with....

WHAT IF....you put a long, 1 inch tall scoop across the front of the car, fed that into a tube (gradually, as to compress the air to it'* max), and let that air out of the other end through just a 3" by 3" square opening....would you be able to cool the air a couple degrees less than the ambient outside temp (asuming high speeds) ? Using the same sorta principle as a fridge, it'd be sorta neat to do a wind tunnel experiment

Of course, you also have to figure out if the gained HP would offset the HP now required by the drag....

I'm confident if my final redesign of my CAI seals up the last gaps, that my system will be pulling air no warmer than 5° warmer than ambient. I think 2000Silverbullet has already matched or exceeded that mark with his system.
