I think there is three groups that things fall into."track only" or "offroad use only""street legal""daily driver"Most bikes or cars that have a modified power plant actually fall into the "track only" category, but are still driven on the street because of one's own "don't ask, don't tell" policy.
I build what the customer wants, and i've been trying to get a hold of Scott at heads up for a few weeks but he never answers or returns his calls. I bought the entire kit from him, almost a 9k sale at my cost, asked him everything I would need for a good reliable setup and he never even recommended an inter cooler, even though i've asked if I needed one in the past. I'm trying to get a hold of him so I can specifically ask his opinion about it.I've talked to some other people in the know and they said I don't need one for what i'm wanting. I can't get as much hp, but i'm not trying to, the turbo kit I got is capable of at least a 100 more hp than i'm using it for, and even then it won't be used that high for long periods of time, it will be at least 200 hp less majority of the time than what it is capable of. I see the advantage of the inter cooler if your trying to get every hp possible out of your motor, but for my intentions, and what we are asking out of the turbo, I think it may be ok without the inter cooler, but as I said, i'm trying to get a hold of Scott now.
I'm very interested in what he says. FWIW,lowering the intake charge temperature will drastically reduce the tendency of the engine to detonate.To me that's all that matters.We usually run these things in the heat and if running with any boost at all possible detonation is what will kill the engine. To me the intercooler is just another layer of cheap insurance.
Builders and component suppliers will many times NOT suggest more items.WHY? Because they want to make the sale,the minimum and unfortunately they do so because of the fear that a few hundred bux more will be a deal breaker. I'd ask the supplier if HE would personally go without an intercooler or use of another method of controlling the intake air temps .FWIW I DO feel that an intercooler is not absolutely necessary at 5-8 pounds boost. But I think above that it's just cheap insurance for a $9K engine.

I believe any turbo/supercharger setup requires an intercooler.
IMO only,that's a maybe -maybe not statement.I don't disagree in the least that all those things should be done to get the very best results but depending on what your goals are may not be absolutely necessary. Many ,many people get great results otherwise.
I know I'm going to catch shi%%%%%%t for this BUT the lolly little Corvair 180 turbo put out 180 HP with only 164 CI air cooled NO inter cooler NO blow off valve NO waste gate One single carburetor and in a 2800 LB car. At 8 PSI of boost. And many of them went 80 to 90 thousend miles before dieing.
Blow offs do two things. 1) aid with minimising cavitation of the air at the compressor. 2) minimise run on when lifting off the throttle with good boost developed.Boost controllers are not strictly required. They maximise the boost as early as possible and help prevent boost spikes. So in effect they make the most of what the turbo can physically offer.The expensive controllers you are referring to Fab like you say also allow varying max levels.btw I run 16 psi, so it's twice as hard for more than twice as long... with less capacity and more power Like I said it will work the old school way but you wont be doing anyone, including the motor, any favours.
