Amusing is how this intercooler is 55mm thinner than the STI unit. But a lot fatter to absorb all that heat in the bars.

It would be a good exercise to flow test both units and get flow rates and pressure drops for comparison.

Looking at the pics of the unit compared to the stock TMIC there is no way it is thinner. Looks twice as thick in the core. I dont think that it will allow enough clearance for a strut brace though and my preference is handling over the cooler.

Thinner in width, not depth.

Depth wise it is 37mm thicker.

Volume wise STI is 8L, Torx is 11L so theoretically there is some more volume. But it will come down to construction, heat soak, flow rate, pressure drop and the efficiency difference of bar and plate versus tube and fin.

There is probably 5hp difference between all the TMIC units out there for an 08+ STI.

Kato, something tells me you're going to get a sore forehead.

Nah, its quite amusing/interesting.

I would also like to see a 08 STI TMIC bench tested locally so we can have some real data. It would also be good to see a back to back run of 08 TMIC vs China TMIC with no tune adjustments to see what the 'gains' are. If someone is willing to pay for the testing, why not get the data?!

I think I spent too many years studying thermodynamics as this stuff interests me!

Hey Trolley...feel free to contribute something positive at any time..... :-)

Thanks Kato. I know that it doesnt seem that probably that there is much benefit to the change either but I at least want to consider and explore the idea before writing it off. If I knew that the strut brace would still fit then I would give it a go and run the base line pull with both before tuning for the new one. I expect that the strut brace wont clear though and handling is going to take priority over power.

I must admit that my old GC8 never gave the feeling of heat soak power drop after standstill to the same level that the GRB does.

And for the record...I have owned a WRX since 2000. I am not a newbie.

I have done and so have many others, but you seem hell bent on ignoring advice on a few issues. Rather than ask questions and then ignore people's advice, why don't you just update your driveway thread with "I'm doing this, this and this to my car (and fuck you if you don't like it) - will keep you all updated with the results".

I dont ignore the advice. I just make sure that the advice that I get is accurate and considerate of my goals before I adopt it.

I am always open to helpful advice. It is why I am a member of PerthWRX to begin with.

Shoot Kev an email and find out for yourself.
