"Uprated" Miami-GT SMIC installation.

I fitted my Greddy 3 row SMIC form inside the wheels arch, no fin bending either.

 

IC are heat exchangers the real test for them is their ability to cool the intake charge. Comparing any modern replacement with a 10+ year old knackered inefficient SMIC is not a real test as most cars of that age with a stock original SMIC will be down on performance. How much power or torque this or that car achieves is specific to that car and that car only.

 

There are several test for IC efficiency; difference in air temp across the cooler and differnce in air temp through the cooler. I have used a laptop monitoring program in conjunction with a K thermo couple in my throttle body an have some data on the effectiveness of my Greddy SMIC. Still got a few more to do before it comes out. I want to compare it to my Greddy FMIC.

 

The design and construction of the core and tanks is critical. Some of the nasty Ebay copies of branded FMIC have such poor quality end tanks that some of core never has sufficient air pressure differential to enable air flow though certain areas dramatically reducing efficiency

 

Until the is temperature differential data on all IC's used in the MKIV becomes available, it is impossible to say one is better than another on dyno figures alone.
