I dyno'd around 430- 448 several times. Ive seen the yanks run 500bhp. But I was in California 2 weeks back, they run FMIC alot more due to the hot weather. As we are cooler climates, TMIC works fine for me.
Im also running a full ceramic coated exhaust from downpipe to tail pipe end, wrc inspired.

....Or in matter of fact what figures are people running with these aftermarket tmic?
I'm running 405 on a Grimmspeed Black TMIC with a Perrin in-wing CAIK and Perrin turbo blanket.
Fitting the turbo blanket allowed an extra 10 bhp after a map tweak.
Whether this was due to keeping the exhaust gasses hotter (and thus, faster flowing) or reducing the heat rising under the TMIC (and thus, a cooler charge), I don't know.
I imported the Grimmspeed from the States at an all in price including shipping, VAT & Duty of £595. That was when a £1 was worth $1.50 (before we all got shafted by ferkin' Brexiteers!), though.

Upgraded tmic, blanket and caik is my next upgrade on my hatch spec c, though I doubt that there is 400hp in my twinscroll.
And perhaps water/meth injection.
Thanks for showing this is viable
So does an under tray help to keep temps down or reduce the flow through the ic and therefore not help , surely it would be easy to make a tray up with a piece of aluminium ? , i have an fsti so it has a wrx ic with sti sprayed on it , i’m only running 340 so is there any benefit going to an sti ic , i’m not bothered about more power , plus at the mo i have very little lag , it’s on full boost around 2200 rpm i assume a bigger ic effects lag ?

Seems like a good build, where did you purchase the tmic from?

Well fitted under trays help channel cold outside air through the heat exchanger of the IC and to an extent help block out engine bay ambient heat. Yes, its easy enough to make your own if you know what you're doing.
Bigger IC will not make any noticeable difference to spool/lag. If any replacement IC cools charge air more efficiently then it gives you cooler charge air and the ability to either make more power or make the same power with a larger safety margin.
If you're not doing prolonged wide open throttle runs then I wouldn't bother upgrading if I were you.
