IAT with home made intake

[DSMULATOR]

I own a custom exhaust shop and was planning on making my own straight intake instead of buying one from Dejon. It would be aluminized tubing and I'd paint the outside. I'm just wondering if, being steel, would that conduct enough heat to increase and effect my intake air temp? I have a FMIC. I've spent 9 months building this 6 bolt and want to start it so I can tune it. I'll probably end up getting an aluminum one on the future, but I'd like to break this thing in first. Any thoughts?

i wouldnt worry about it much.. ive used steel intakes before and never noticed a difference.

I recently made one (see that thread for mine and a lot others), and i see 40* drop in intake temp and never goes past 100degrees on the hottest days.

aluminum conducts heat better than steel.. either way both will be saturated by the temps around them and the difference between the 2 is null.

Thanks for the link. Unfortunatley I put my oil cooler in my SMIC spot with the ducting to keep it cool. I'll have to get a pipe and put it up through the whole where the UICP connects to the stock SMIC and grab some cool air that way. I am also planning on making up a heat shield around my filter. Hopefully that keeps the temps down as much as possible.

Dont worry about whether its steel or aluminum. It wont make much diference.

Thats exactly what I did. My cars a DD in the summer & we do get rain here & from time to time it can be heavy. I didn't want the hassle of having a low, exposed filter so I first made a heat shield around the filter itself (in stock location) & this gained me a nice 30 or so deg drop in inlet temp. The one thing I noticed is it would still eventually heat up while sitting in traffic on hot days & eventually see the temps I was seeing pre heat shield, though it did take much longer. So like others have done I found some automotive ducting that you are able to bend & it holds its shape (looks like an acordian) & routed it from the opening on the pass side up to the hole where the stock IC pipes ran. This dropped the cruise even abit more & keeps the temps lower in all conditions. It also cools the inlet temps back down much faster once you have heated it up abit from sitting.

1g's don't have this issue but like coolent temp, 2g's will pull timing depending on inlet temp. I believe it goes something like 73F, no timing pulled, 100F 1 deg pulled & then somwhere around 120 or 130 2 deg pulled, etc.

Your turbo will heat the air more than the differance between Steel and aluminized steel. A couple layers of paint is good enough insulation.

If your really worried there's always the different types of powder coating that do a very good job of insulating things.

I got some 'tin foil' looking insulation from Home Depot like I saw in one of those posts. I am going to wrap the entire intake in that. I'm more concerned with the go than the show. I've got a different UICP than most so a pre-made one from Dejon won't fit anyway, i gotta bend it up myself.

My friend had a honda with no intake, just a cone stuck onto the throttle body and we went through a puddle in Jax, FL and bent two rods. I'm all set with taking that chance, ducting and heat wrapping will be plenty for me.
