As the title, if the air intake is ducted to the side scoop and that area shielded from the engine side so the intake is only getting fresh air, is that not cold enough ?
Or is it that an intercooler makes the air colder than the fresh air?
Mike
The air is taken in at the airbox and then passes through the supercharger which compresses and heats it, it is then the job of the intercooler to cool the heated air down by as much as possible before combustion 
Now it makes sense, so the intercooler is down stream of the supercharger.
Ok then i think i am going to get the ronin SC off sinc’s but that has no intercooler and they claim a 50bhp increase so on my car say 240bhp at flywheel but i have read threads on here, possibly some of yours (Boothy) saying that a low air charge temp is needed to extract more power does 240 seem too much?
Exactly, an intercooled solution is always better than any non intercooled solution despite what you might read. However thats not to say there is anything wrong with the Katana.
It seems like a good set up and seems to give a pretty consistant result of 240bhp (flywheel) when tested, I am guessing the intake temps get pretty hot on track and you will loose a good chunk of your power under those conditions but quite a few guys track them with no problem so your not putting anything in danger and you can bolt a chargecooler on later.
The other option is the new VF set up from the states wich uses an air to air intercooler and gives much bigger gains than the stock Katana but I dont know much about price or availability here tbh. Frank who designed the Katana seems to really rate it though so it can’t be bad.

It’s been fine on mine without an intercooler. Katana/Ronin SC only runs 7PSI of boost so its not like temps get out of control. Heaksink isn’t an issue, the only way I can see it being an issue is long periods on track (> 20 mins) of sustained high rpm where the intake temps will get very hot. I’ve opened the side pod scoop on the air intake to get more air into the induction kit and it makes a difference. If you want to go beyond 7PSI then you need an intercooler or charge cooler otherwise the heat will probably melt your pistons.
Thanks for that.
Did you have your fitted by Sinclairs and did it live up to your expectations.
Mike
Yes, mine was one of the first to be fitted at Sinclaires.
I got what I paid for (~50whp & 25lb/ft), the power delivery is sup er smooth so its deceptively fast and pulls all the way to the limiter. You get used to the power after a while though so there is always more power available for �. It idles better than stock and Sinclaires can do a custom map specific to your engine & other mods you might have. It’s probably worth beefing up your brakes as well to handle the extra power.
