Just some photos of my attemps to beat the heat:

Wrapped DP:


Cooler tilt and BoostLogic turbo blanket:



Some DIY-heatshielding , the shield between turbo and cooler goes all the way down and has this channel for cold air from the scoop. Works really nicely to keep turbo heat from soaking the cooler.


Head Tank Insulators from carldavey.co.uk:


These nice tiny parts alone dropped the intake manifold temperature over 10C on the passanger side (~18F) and over 3C on drivers side.

Measured everything before/after with infrared temp:




All in all, really nice results for small money. I have K-type thermoprobes before and after intercooler and all these small things add up lowering charge temps significantly! Even without the temp sensors it is really easy to notice how the ic is MUCH more colder now than before.

Here's the exact results if anybody's interested. I drove the exact same ~30km route on a highway with steady 120km/h before and after the insulator install. Ambient temp was +13C, IAT +14C, turbo outlet air temp +50C, intercooler outlet air temp +22C.

Averaged measurements without Head Tank Insulators:
Code:
Intake manifold surface, passanger side: 68.2C
Intake manifold surface, driver's side:  54.5C
Averaged measurements with Head Tank Insulators:
Code:
Intake manifold surface, passanger side: 58.0C
Intake manifold surface, driver's side:  51.0C
So in my test the temp change was -10.2C on passanger side, and -3.5C on drivers side.

Nice work Foobari!

Good to see some heat shedding ideas put to work.

I have one shot which I guess shows the idea nicely. I tried to create sort of double insulation layers and a channel of cold air in between. This channel is flowing with cold air from the hood scoop whenever the car is moving.

I posted this on IWSTI. This simple mod should help the GR guys with their underhood temps. The stock configuration does nothing to get rid of heat. You wonder why Subaru even put a vent there.









I haven't taken any measurements but I'm convinced its reducing under hood temps just by a the amount heat that comes out of there. When the fan is running I can actually hear the air coming out. Whether this mod does anything beneficial or not is still up for debate but it only took 15 minutes and a holesaw to do.

More cooling!

I was kind of sceptical about the Zero/Sports cooling plate, but ordered it anyway. Well, today I received it and here are some results.






Just checking the fit:


The rubber seal from the stock splitter and IC water spray nozzle.



And there it is:





The results:

On a highway at steady 120km/h (~75mph) the air temp measured right between IC and throttle plate came down about 2C, not much. But, when cruising around at 60km/h (little less than 40mph), the air temp came down 5-6C compared to the stock splitter. So, according to my measurements it seems that the stock splitter does a reasonably good job at higher speeds, but the Zero/Sports clearly outperforms it when the speeds are not so high.

Note: My car is 2.0 EDM '03 WRX STi with the large scoop.

After reading this thread, I went ahead and ordered some of the DEI Titanium wrap, DEI Cool Tape, DEI Silicone Coating, & a PTP Turbo Blanket.

I've also been looking for an upgraded splitter for my GR STi, but the only one seems to be the Zero/Sports: http://preracing.com/catalog/product...grb-sti-p-1905

& the Subtle Solutions: http://www.subtle-solutions.com/prod...products_id=84


They're both quite pricey & I'm wondering if they are even worth it. If I look at my TMIC, it's obvious that the lower 1/4 of it is not getting as much air as the upper 3/4 because the fins are perfectly straight and the finish looks untarnished.

wow, all of these "beat the heat" products make me want to add them to my car project list but I am not so sure if I really NEED to. I do have a TBE and a tune running 19PSI with a stock TMIC. I might consider this if I purchase an upgraded TMIC but if I go that route, I'm going to upgrade the turbo (and complementing upgrades) as well, then another tune. decisions, decisions, decisions

I just added a Process West TMIC with it's own splitter that covers the entire core. It's a perfect fit. I've done no testing of my own.

that Process West TMIC is pricey so I don't know if it's worth the money but it does seem to be made really well. For the price, it comes with everything? air splitter, hoses, clamps, BPV gasket and bolts?

Now imagine the PW TMIC with all of the heat tape, that would be one sweet mod.

Yes, it comes with all that which is why its a good deal. Also, there is no other TMIC on the market that includes its own custom fit splitter.

A good seal and splitter will go a long way to maximize cooling to your TMIC. The PW unit is a real nice setup. We actually carry those as well

I shot you a PM dieder.

Everything but a gasket. The second image shows I added a length of foam caulk backing to fill a gap along the leading edge where it meets the hood. Other than that the fitment is perfect.

The IC is quite heavy. The tank looks to be ~ 4mm solid aluminum. I'm not sure if a lighter, thinner IC would be best as it would dissipate heat more quickly.

Yeah, this thread is almost sticky-worthy. I'm going to do up my TMIC in gold before summer hits.

I did get the turbo blanket and it made a huge difference under hood. Even on back to back dyno runs last summer, I could put my hand right in between the turbo and intercooler and feel more heat off the block than the turbo. DEI makes some cool stuff (no pun intended.)
