TMIC vs FMIC

[Gripless]

Yeah well I know the stock one is heat soaked.

dont expect much but think 250 kW at the wheels from factory turbo will be a laugh.

Concise summary? 

-  Make sure your tuner uses a dedicated fan when your TMIC equipped car is on the dyno. 

-  If you are running a road car with mild modifications, stick with a TMIC design. If you are pushing the envelope of what constitutes a “road car” then consider a V Mounted aftermarket kit. 

-  If you are running a race car or very heavily modified road car pushing big boost, then consider a V Mounted aftermarket kit...or move to a FMIC setup for outright performance.

its all kinda irrelevant because the so called advantage which one might insinuate to make it an unfair comparison is very much the whole point of moving to the superior cooling design. the true function of intercooler is not directly a power upgrade item, it is all about improving efficiency of the turbocharger system. better intercooler will provide benefits of lower pressure drop and better at transferring heat away from the charged air. from first post it was already stated that same boost level was retained but it netted more power. the reason for this would have been the ECU did not have to trigger the intake temp safety adjustments with front mount hence without even any tuning differences, the power run would have shown higher power. i know in my car with the twisted turbo setup, it was like 0.5cm from touching the top mount hence heat soak was always evident and not something i could avoid with any kind of top mount within space i got in my engine bay. intake temps not long after cold start quickly rose to 30-35, peak boost at 55 celcius which would put it at 30+ degrees above ambient temps.. with my front mount i've never seen IAT rise higher than 28 degrees even in summer

Engine work is all a bit above me at the moment so most likely not a gain of 35kw its more the intercooler has allowed them to maintain the extra 35kw through the power runs?

yep most likely, however we don't have all the facts in front of us so there is another possibility. the alternative answer would be that the previous intercooler was so inefficient that the tune it self was compromised and now that the temps are in the range of 20-30c they're able to add in more timing / fuel as there is now more denser air (more oxygen in the cooler air helps a bit with this too) = better combusion =  cooler engine = safer engine = more power with same boost level.

 

in my own example that i provided from my car, when switching from top mount to front mount i didnt make extra more power just from this as tune was already at limits and the power runs/tune was done at PBMS where they have proper top mount cooling setup, however my tune was setup to compensate for IAT so as i drove it hard during the hotter months, the ECU was pulling timing while driving to keep engine temps down hence i'd be driving around with fair bit less power on road than what i had on dyno which would have made that setup a bad choice for track use. not only is my IAT cooler but my coolant and oil temps have also been cooler since switching over which was weird because in theory this big object in front of radiator i would have thought would make it less efficient in that respect. goes without saying though that a good quality intercooler core definitely plays a big role in all this.
