If someone is willing to tape a thermometer in their stock airbox. I will do the same and we can see how much of a temperature change there is.

Also, thank you Richard for your help. I have finally completed mine.

 

This was done a long time ago. You can get the temp measurements here:

Moving to S2000 talk.

 

The silver color material is R 13 double side foil bubble insulation. I should have mentioned that xviper's "radmat mod" was the inspiration for much of the use of this stuff. Insulating the inside of the air box was sort of a "carry on" idea.

I could put a thermometer in the airbox, but this thing draws in so much outside air, the temp of the outside air would be a big variable and I don't know if the temp inside would tell us much by itself. I do know for sure that the flapper valve opens at idle when the car is at rest. I removed the air box cover and sealed the top with clear plastic to observe this. Also, I know for sure that the scoop behind the grill puts the air box into ram air at speed. You see, my first fabricated flapper valve was made to small and too flimsy. The ram air pressure broke it loose and forced the flapper down he side pipe and into the fender well after a highway run.

Thanks,
Richard

 

It's about 48* here right now. So, what I'll do is...get temperature readings in my airbox like it is now. Then, I'll return it to stock and do the same. That way it will be accurate.

I will redo this when it gets about 90*. I feel it will show more change when the engine bay is hotter.

Notes:

1. I only have the inside of my airbox covered with this, not the intake tube like dolebludger.

2. I will be using a basic household thermometer.

3. I'm not driving tonight. &

 

With my airbox lid off, I layed a gas powered blower in front of the air scoop and held my hand behind the opening of my airbox. Air was indeed being rushed into the airbox.

I'll have to try that plastic top trick to see if the flapper also closes with the ram air. (just to make sure I have all the nuts & bolts in place.)

 

is that cooling plate conected to the intake box?......if it does, is that considered a cold air intake??

 

for Richard.!!!
Nice job!
I have nearly the same set-up,minus insulation,and it.!!!

 

S2K Kidd:

The cooling plate incorporates a CAI in its design, which is actually that raised area in the plate right in font of the stock intake. What this doe is to move the point of frontal air intake from the stock horn (which is under the hood) to a point between the radiator and the grill. And yes, it is sealed to the stock horn. The air scoop I built directs air when the car is moving to the new air intake point. this cooling plate/CAI is made by AUT or Garage Defend -- and both have Sponsor Group Buys on this forum where you may learn more about this product.

Someone has asked me how this mod performs at high speeds. Quite well above VTEC --- and even better below VTEC. Start-outs at 1.5K rpm are now possible, and the engine pulls up quickly at that. In the 3.5K - 4K rpm range the power increase is VERY noticeable. Almost feels as if you have VTEC'd already. Some have remarked that the transition to VTEC isn't as noticeable, but that is because you are already making increased power when you enter VTEC. As for high mph speeds, it works quite well, as the higher the car's airspeed, the greater the ram air effect. It's neat if you live in a windy area as I do, because you can't feel an strain in a strong headwind. The ram air cancels the increased drag.

Thanks,
Richard

 

Thanks for the explanation Dolebludger im very intrested in that design i was always scared of real CAI cause of Hydrolock but this is a way safer design probally going to pick 1 up very soon thanks again......
