About how much horsepower can this tmic handle?
The highest dyno numbers we have seen was 345 at the wheels with someone running methanol injection.
Is there any cooling advantage in purchasing the optional aluminum shroud vs. using the OEM plastic shroud?
Some people feel the aluminum shroud seals the hood scoop against it better for more air.
anyone have an idea how much whp gain over stock ?
One of the things you will notice with the TMIC is the reduced engine knock under load which gets you more power. Expect to see a ~15 wheel hp gain.
I have an 07 Mazda3. Would this work For my car?
This will only work with a Turbo Mazdaspeed vehicle.
Is it safe to run this IC without the shroud? Like if rain came in the hood scoop? And what kind of hp gains??? Debating between this and a DP
We recommend running the OEM shroud if you do not get the optional one we sell. Rain comes through the hood scoop and falls through the intercooler with or without the seal. The seal is there to make the TMIC more efficient.
With this installed in a stock cx-7 will it need to be tuned at all?
With the TMIC we would recommend a tune. Check out Versatune.
Am I able to use the standard rubber and plastic shroud that comes stock on the Gen II's with this or is it better getting the optional shroud?
Yes you can use the OEM shroud and hood seal.
