Does anyone still modify stock intercooler necks anymore?

[Big H]

I know ArizonaGN had a service where they perform the neck mod, does anyone else do something similar?

Another option would be to post a wanted ad for a Duttweiller necked stock intercooler.
They are out there & would probably save you a bunch of cash.
You can sell your stock intercooler to help offset this cost .

The kneck can be modified by the right guy
But before you seek understand there really is no gain there unless you are pushing the stock intercooler really hard in the right conditions.
It's just better to upgrade it if you really want to make power that is consistent.

I've taken stock motored cars stock turbo intercooler cars into the 11s at full weight and the neck didn't do much at that level
Beyond that performance level an upgraded intercooler is the smarter choice

I’m sure I’m not in the 11s yet so I’ll just stick with the factory setup.

The stock setup with a single nozzle alky setup really shines at that performance level with the stock stuff.
That intercooler just doesn't cool the air too well combine that with a small cast turbo and the heat really hurts the combo
That is until meth cools it down

just an fyi....by adding the dutt neck /type of mod w/o changing anything else will yield a 1-2 psi in boost...there are better options

From "back in the day" work....
When aftermkt coolers started becoming a "thing" there were some tests done to push their use.
In a new condition, the OEM was said to be 58% efficient, and became less as boost was increased.
Remember, this engine was operating at <20psi with the factory chipset.
As the IC was subjected to road debris, oil contamination, vibration, heat cycles, it became even less efficient.
As the cooler aged, the solder joints deteriorated, causing even more loss.
