3.3TT DIY intakes w/Heat shielding drop about 0.2sec off 0-60

[Rakker]

Very nice work! I just installed my filters last night into the lower half of the boxes like you. Mine are held down by the cross braces but it looks like yours are strapped down to the box? How are the heat shields attached? To the lower box as well?

Yeah I zip tied my down. Yeah not the best looking but I didn't want it loose or touching the cross brace. I soddered aluminium brackets to mine and bolted them down using an existing bolt. The shield sits in the slot where the top of the OEM box sat in the lower. I cut small slots it the lower boxes outer lip for those locations where the shield extends beyond the box. Here are a few pics of the brackets. They are partially covered by the heat barrier material though.

DYI heat shields looking goooooooooooood guys
what was the final price ?

Yeah once I folded over the edges of the aluminium and started shaping it became rigid enough. I haven't done IAT testing with/without shields but I don't really see a difference between it now compared to OEM. If anything there may be an snall increase in IAT while not moving but none at 30 mph+. Look into the heat barrier material, it's not expensive and I think it helps especially on that cross brace.

Something plastic/rubber might be a better option, compared to steel/aluminum. Has anyone tried that?

Something like a big Rubbermaid garbage can could be easily cut/shaped and then bolted down to something under the hood to retain the shape. It should do a lot better at isolating the filters from heat but won't be pretty to look at.

Not including the elbows and filters, the heatshields only were 15 for the sheet of steel (I have lots of extra left over) and 5 for nuts and bolts. I already had the foam tape but that's usually 5 to 10 bucks. I'll be spraying it with plastidip later which is stupidly overpriced in Canada at about 20 bucks a can. All in about 50 to 60 bucks plus whatever your time is worth.

Looking forward to the final set up pics !

Have you guys thought about adding weather stripping to the top of the cross braces? I noticed there’s a fairly significant gap between the top of the brace and the hood, even when the hood is closed.

How hot does this get? my 90* is pressed pretty hard against this by the strut brace. Could it potentially melt it?

Are you naked ?

 

[Pnasty]

LMAO I was not paying attention. Hopped out of bed and went straight to work on the car thankfully I have pants on

Turn the 90 so the filter is facing the front of the car and it should be fine.
I did this mod the other day with the same elbows, plastic. I was worried about that but then I thought, The OE filter boxes are made of plastic too.

I used the 90 degree elbow but in such a way that I could retain the lower half of the factory airbox.

I'm trying to do this right now but for some reason it won't fit in the lower half of factory airbox. It sticks out and the strut bar won't fit.

Going to need to provide pictures so we can diagnose. Mine weren't perfect. The driver side elbow does touch the brace.

I ended up getting it lol.

I just don’t know if the car needs all this, engine temps at idle are less important than rate of iat drop once moving. IMO I’m starting to think he stock box will allow a quicker temp drop as it literally is the only cold air intake of the bunch due to the sealed system. I’m really uncertain what way to go. Can anyone verify a true performance gain over stock box?

Dyno’s I’ve watched seem to show verrrry little gains on any of the setups, but catbacks literally grabbing up to 20 hp/tp.

 

[KiaStingerNewb]

I like the DIY intake for all the turbo sounds mostly. The gains may be 10-15 according to multiple people, but as someone here already pointed out you aren't particularly likely to FEEL 10 hp in a 4000 LBS car.

Here are mine. Kinda hard to see because it's night time. The 90 degree pipe was actually right next to the filters so I just used that black one. It's thicker than the chrome one people were using that said "Not for use with turbochargers" or whatever. My only concern was the angle kinda made the seal between filter+90 not flush, BUT I tightened down the hose clamp so hard that I doubt there is a leak, just wish there was an easy way to test for air leak.

I don't believe you will see even 10 hp FCC rom intakes alone. Maybe 2-3 hp

I would like to see some real comparison dyno also.

I was under the impression the stock intake is a choke point, but regardless I didn't do it for power gains in itself, but rather more air flow for OTHER supporting mods and to support the JB4. I care more about the sounds than a handful of horsepower from an intake.

 

[NS_Stinger]

On a factory car gains would be minimal with just an intake but any open intake paired with JB4 should see a significant bump in power.

I’ve seen this more than once:

I honestly believe at this point that the drop in filter is the best alternative vs cost time...this debate has been ongoing for ages in c6 forums, mustang as well. No final answer.

I think faking out the iat, panel filters, and a better catback combined with a more efficient inter cooler? Would this not be a more effective setup for a wide open pull?
