Some people in this thread are mistaking the difference between:

radiant heat transfer and convective heat transfer

and:

heat capacity and thermal conductivity.

 

Got it.

Do you mind expanding on that, Mike?


Get ready to take notes... we are about to learn something else....

 

I'll just leave it at this...

the optimal insulation is usually something that alternates layers of reflective (foil, mylar) and non-reflective (fiberglass, foam).

The reflective layers block out radiative heat transfer (heat you feel when you put your hand near a metal that is red-hot)

the non-reflective layers prevent air molecules from bumping into a hot surface and picking up heat... this is convective heat transfer. (heat you feel coming out of a hot oven)

There will be diminishing returns after the first couple of layers, but that's the general idea.

You don't want JUST aluminum foil because it has a high thermal conductivity. You need something with a low thermal conductivity to reduce convective heat transfer.

 

nice intake

 

I was kinda counting on the (reportedly) really thick plastic box to serve as the low conductivity/reflectivity layer and the foil to address the high reflectivity, high conductivity layer... just for the purpose of batting around the idea, of course. I would never put foil on the outside of my airbox, but since someone brought it up I figured I'd play with it a bit.

Unlike most cars, this is a real challenge since the OEM airbox and intake tube are pretty damn good from the start.

 

Isn't gold the best of both worlds?

 

Gold has a low melting point... But it doesn't corrode and is the best electrical conductor.

 

I would say mylar is the best of both worlds...gold is mostly used where oxidation cannot be tolerated.

 

Sweet intake!

Which strut bar is that? Crawford or APS?
I have a similar setup (stillen airbox, mrev2, crawford plenum) but went with the Stillen STB which is apparently a no-no with the Stillen airbox because the MAF gets in the way.
Also, any hood rubbing with the plenum?

To those wondering about heat coming in from the fan....
On the dyno my runs got worse instead of improving like many people say it should....
Not drawing any solid conclusions since plenum heat may have been a factor but I did not see any Popcharger guys drop power after each run...

 

Crawford upper plenum & strut tower bar


no rubbing at all.


Did Julian run cars with their hoods up or closed? i don't remember.

Side note: i'm actually get sick of this thread, it just won't die.

 

Good ideas sprang up from the foil heh, im sure someone could make something cool looking yet functional.

 

Where does the veturi ring go and how is it fastened?

 

Yes, it does. Comes in the same bag that holds the installation isntructions along with directions on getting a replacement.

 

haha i guess i threw mine in the trash!

 

Couple questions for you.

1. Does this intake change the daily driving of the car such as bogging, heatsoak, less torque, less responsive, needing to press the gas more for acceleration?

2. Do you believe its an improvement over stock airbox under normal driving and WOT?

Thank you. I think i will be changing my pop charger, just had to ask before i do.

 

Feels the same really, just more noise than stock.

I'm hoping there is a difference at WOT. I doubt its anymore than 5hp. I'd be lying if i said i could feel it pull harder.

Not much of a difference but good for when you you're trying to pull every last horsepower out of the engine n/a.

 

thanks for the responses. I'm just afraid i'm going to dish out even more money for something that i lose daily drivability out of. I know i'm N/A but i think it's kinda dumb to go FI while still paying for the car.

As long as i dont' lose anymore usable torque down low(test pipes), i'm going to get one of these.
