Default AutoDynasty TMIC vs. USDM STi TMIC

Ok lets see here. There has been quite a bit of talk on this board and iwsti.com about the 'ebay TMICs'. Well I am here to tell you that they are pretty 'ok' in my book - talk about China mass production in action [heh].

Anyway onto the facts:
-This is the one on Ebay that costs $145 buy it now price with 45 s/h.
-The TMIC shipping/packing material was pretty minimal but overall the intercooler was in good shape. The drivers side was a little bent in but just barely and there were 1 or 2 light scratches so not a big deal for me.
-Fitment was very nice. The only >< issue was the intercooler does tend to sit lower on the passenger side but nothing the provided shim can't take care of.
-No issues on reusing the stock recirc valve and other gaskets from the y-pipe
-I did grind out some of the entry port material since they were not cast the best and tapering inwards (decreasing hole size).


On the Pre/Post intercooler temps I have to say that I did a fully sealed shroud to custom fit this new intercooler. I never tried it without really.

My basic setup for context:
-TEC 50trim - TD06H-T04E50 trim turbo @ 21psi @ 5000ft asl
-APS 3" catless exhaust
-Helix 4-1 headers uncoated
-Tial 38mm EWG (11psi spring) plumbed back into DP
-Perrin turbo inlet + SAMCO MAF hose + K/N drop in
-JECS/NISMO 720cc injectors + GSS342
-ECUTek relfash with AVC-R controlling boost
-SP Engineering pre/post intercooler gauge

Pre/Post intercooler temp data:
-Cruising the stock TMIC would typically be 7-10F over ambient
-Cruising with the Dynasty TMIC I have been seeing 4-8F over ambient
-Doing a 1-4th gear pull on the stock TMIC at 70F ambient temps with waterspray on over 12psi. Temps at the end of the run coming out of the turbo ~290F and out of the intercooler were ~120F.
-Doing a 1-4th gear pull on the Dynasty TMIC at 70F ambient temps with waterspray on over 12psi. Temps at the end of the run coming out of the turbo ~250F and out of the intercooler were ~100F.
-Stock TMIC with a AVC-R DC of 67% I would hit ~ 1.40 kg/cm2
-Dynasty TMIC with AVC-R DC of 67% I hit ~ 1.55 kg/cm2. So a difference of about .15kg/cm2 = 2.175psi. So I have observed about 2 psi less pressure drop across the Dynasty intercooler compared to stock.

So overall the biggest advantage I see with the ebay TMICs (Dynasty in my case) is the lower pressure drop with higher air flows with larger turbos. In my case I am flowing about 290-300g/sec which is about 42-43lbs/min. The secondary benifits of the 2psi lower pressure drop is the turbo PRs drop = more efficient = less heat generated by the turbo.

It's not a 'huge' improvement overall but for $145 it's a DARN good deal IMHO. Comparing this TMIC to the TXS v1 TMIC I bought for my 02 WRX 3 years ago there is VERY VERY little difference. Well except the Dynasty fits better [heh] and is only $145 compared to $800 of the TXS one 3 years ago.

Cheers.

Does the autodynasty kit come with any extras? Y-pipe? Worthless B.O.V.?

So the stock y-pipe worked fine with the auto dynasty top-mount, I'm assuming?

So it seems with any of the EBAY TMICs, a hose kit would be a good purchase then?

I'm pretty sure the ssautochrome one comes with hoses.

Someone else had a problem with their autodyansty one being damaged in shipping, but said autodyansty is super easy to deal with about getting a new one, which seems to be the primary complaint with ssautochrome.

The stock STi y-pipe worked just fine for me. I don't know about WRX y-pipe fitment.

Yes. I emailed them about a dent, and they replied within 3 days, and offered to send a new one.

The spot where mine was dented was actually HELPFUL in allowing it to mount to the stock location, so I kept the dented one. It holds pressure up to 20lbs (which was as far as I bothered to test), and it works GREAT with Perrin hoses.

I DID NOT have to mod the perrin y pipe to fit.

SOTC.

Installed my Auto Dynasty TMIC with no issues. Just need to work out the hood scoope spliter rubbing again my hard lines. My stock STI Y pipe did not fit. I have the solid piece...

I ended up buying and using an Auto Dynasty Y pipe with OEM gaskets. No leaks.

Does the autodynasty tmic or ssautochrome tmic allow a front strut bar? I know the whiteline bar KSB-599 fits with 06's, so it is presumably farther away from the ic, but I'm not sure if it is far enough back to clear these huge cores.

Thanks,

Steve

I just bought an SSAC TMIC. The AD TMIC was exactly the same price, but if I remember correctly, the X02 was more expensive? I wouldn't expect there to be much difference between any of the three and I'll take my chances with the SSAC...

Did your ssac tmic come with a y pipe? Did you use it?

Yes, it came with everything that you'll need to get it installed. I had it installed professionally because I was worried about fitment issues but they didn't have a problem at all and everything went well. The only thing is, you can only bolt in one side of the tmic because fitment wasn't exactly perfect. BUT, with all of the hoses connected, this tmic isn't moving anywhere.

The only thing I haven't done yet is install a new intercooler air splitter and shroud. I already bought the parts from www.subarugenuineparts.com. Without a new splitter, only some of the air flow from the outside will be going into your intercooler. HOWEVER, this is better than not having a splitter at all which is what some people do because the shroud (or bellows - which is the rubber trim) prevents heat from the engine bay to go into the intercooler. So without the shroud, you may encounter heat soak problems (especially on a hot day when you are stuck in traffic)

I had purchased an Autodynasty TMIC, both times I got it (after a lengthy failed attempted claim with UPS), they were shipped bent. Ended up refunding me (again, after a length spat with Autodynasty)--and I ended up buying a X02 TMIC from Renick motorsports, came perfectly shipped. Quality was considerably better than the Autodynasty. FWIW, I will never buy Autodynasty again...search for my post on my review of Autodynasty's TMIC...
