Don't uses any DSM bypass.
The 1G can do maybe 16-18psi when crushed but it leaks like a sieve at nearly any psi level.
Same with any DSM intercooler. Small & inefficient.
You are better off running 2-3psi less boost then having the intercooler drop 2-3psi across it. That's after you find a place to mount it where is gets airflow.
If you want an air to air get a small flat Spearco (their 4x6x18 IIRC) or angle fit a StarQuest FMIC. You will have issues with airflow to the radiator and subsequent piping though.
Remember with any F/I setup you would be running the thicker SVT radiator anyway unless you were quite insane.
