did you test to see how well it reflects heat? Over the IM there should not be any excessive heat so I would not expect there to be a problem. The goal is to trap whatever temp the IM is at and let its temp rise up more over ambient. I am seeing mine reaching +30~35*f above ambient at times after the motor is heat soaked. The guys on ecomodder.com recommend the WAI to get intake temps up so the amount of air density goes down which would drop the amount of injected fuel on each squirt. My first tank which was a short fill @ 100~125 miles (?) gave me a 16.1 or so mpg tank BUT... I was at a pump that had the truck on a slight hill which caused problems getting the tank filled. ended up at 2 pumps to get it done so it was not the normal 2 click and done fill. (that 16.1 was recalculated to be over 17 after learning the speedo was way off)


Will be filling up tonight (all "city" miles on this tank so far) for the commute next week. That tank will be a good indicator. I will cover up the back side of the IM by the end of the day. (it is still exposed).

 

It's heatshield aluminium bubble foil ??? don't know the translation will be okay

I'm not to worried either, it might just melt a little, but think i would be safe, my air scoop in the hood is directly on the IM and with these outside temps i don't expect problems.

I will see tomorrow what the difference in IAT temps are gonna be, they will be higher no doubt, i covered as much as i could, all the way to the back.
I only made one trip to work on this tank, so this will result in a 386-52=334 miles testrun with the "IM Blanket", if you wanna test 200 Miles only, i'll report sooner

 

whatever normal is for you... mpg should he consistent from tank to tank, then would change +/- what is normal.

 

Installed a cover for the back half of my IM...

 

Was affraid to cover the throttle Lever/Cable....think it might get stuck....just be carefull

 

the material i have is to rigid too get stuck... will be fine but will double check this afternoon


no issues with setup. seeing temps 40-50* hotter then ambient on the low speed streets, 30+ on the hiway. going to fill up for the next 200 miles at the end of the day. temps are supposed to drop starting tomorrow.

 

Well, driven 52 Miles with the blanket, no problems, but no results either, IAT seems to be a little higher, about 5 F, so that ain't much.

Can't say anything on fuel economy, we have bad weather all week, with stormy conditions by friday, it's rainy and windy all week.

I'll keep the blanket on and we'll see, but i expected more from it, might be the airscoop in the hood, as soon as i decrease in speed, for example taken the exit and the TB closes, i see a increase in IAT temp.

 

Thanks for the feedback, it sounds like your CAI is drawing in colder air from somewhere. The scoup is also most like dumping air towards the throttle body area or behind it and getting in down past the throttle linkage area. Since adding the 2nd piece to cover the back it appears to be holding heat better which would give better feedback on its effectiveness or lack of.

I should have 190~200 miles by the end of tomorrow and will have feedback then. The reason I went this route... I know on the Ram with IATs up there around 100* it gives the best mpg's across a tank. With the IM blanket in place I am seing 90+ temps around town yesterday (the only day with both in place). This mornings drive in, ambient temps were down around 40 & saw a peak IAT in the mid 80's. Off throttle temps climbed into the 90's and dropped back down when on throttle again. Going to block the fender opening (again) after this tank to see if I can drive up IATs a bit higher to experiment with.

Also should note, it took 20ish minutes to get IATs up into the 80's on the 40ish minute drive in. Never did pay attention to what they were before the IM blankets, can easily pull them to compare against.

 

I noticed the same on temp rising, it takes some 15 to 20 minutes to rise higher as without the blanket.

I'm going to look if i can get the CAI blocked a bit from the cold air

 

drive home IATs were up into the mid 90's, 70ish uncorrected miles on odometer, gauge still at full line.

going to use a gear ratio calculator and get a solid offset for the setup, then recalculate the same for previous exu setup (the 3.3% offset for tire size) for a better comparison
