Sealing Airaid Intake

[kinder]

If you want to cover some more avenues you can get some heat reflective tape and blankets from DEI.

or go all out and add in one of their Cryo kits.

Thanks Kinder, that will be phase two for sure

I finally finished sealing the box, and have some good data.  Ambient temperature was 82, I logged without and with the lid on, and also with both front and rear AC on (wanted to simulate worst case)

IAT1 max value without lid = 127.4
IAT1 max value with lid = 114.8
IAT1 at redline without lid = 120.2
IAT1 at redline with lid = 96.8
Max Knock at Full Throttle without lid = .75
Max Knock at Full Throttle with lid = 0
Zero to Sixty without lid = 5.40
Zero to Sixty with lid = 5.28

The biggest take from this is the 23.4 degree difference in IAT with vs without the lid at redline, and the slightly over .1 second increase in zero to sixty   Very pleased, with time I will insulate the box to try and get closer to ambient.

Gotta like the no-knock at full throttle.  Well done!  Hopefully you have a How To in the offing

Very nice! Thanks for the update

Excellent! I've got plexiglass and some different rubber grommet on the way as well. May attach my lid a little  differently since its a SHO and not a Flex (not as much clearance).

Now that you have an enclosed box (similar to stock) are you willing to put stock one back in and try again? Unless someone else has results for a stock box?

Im gonna stick a pizza box on mine at track tonite hahahaha. Goin to Home Depot in morning

the Pizza box mod... oh this is one for the record

Kinda makes you wonder why it didn't come with a lid from Airaid?

[kinder]

Just a thought.... did you happen to see any AFR differences? Can you see what if any fuel adjustments were made to keep the afr in the tune's range? I know the tune would adjust for that but curious if the lid on the box affected the amount of air it was taking in.

[boostedflex]

AFR bank 1 and STFT were unchanged which I think is a good sign.  The only parameter I noticed really change was .5 degrees average more timing for the 0 to 60 run, which I guess when viewed with the .75 degrees of knock retard equates to a nice bump   I will try and do a run with the stock box, but I have so little free time not sure when I will get to it.  As for the write up I will try and do something, but it was fairly easy.  Probably the easiest way to do it is get a piece of Lexan from Home Depot, put it over the box, trace the outline of the weather stripping with a sharpy, and cut it with a jig saw (using a fine blade).  To hold it down, all I used was angle brackets bolted to the air box, then long screws coming up from the angle brackets thru the Lexan to hold it down.

Has anyone thought of using Kydex to form a lid?

Had to look up what Kydex was but that seems interesting.  There are a number of complex curves/bends in the Airaid top that make sealing it difficult.  This might be an interesting approach if they make it thick enough to prevent it getting sucked down on to the filter...

I've worked with kydex a little bit  making holsters and mag pouches.  I think it would work well in this application.

You can easily form it with a hot air gun or flat griddle.

They make it pretty thick pretty thick, but even in thin form, once it cools its very stiff.


I usually buy my kydex from knife kits.com.

I probably still have some laying around if someone wants to try it. Just pay the shipping and you can have it.

I'll check once I get home.

I think I'd be a little worried about the kydex deforming from the underhood heat.
