The parts you have will add minimal power gains. Intercoolers don't add power they keep you from heat soaking. The one thing that will help you is ams wastegate rods. Plenum and TB will give u very little hp with stock k16s.
Exhaust will help you because the stock exhaust is so restrictive.
Does anyone have a pic of a billet turbo?

Get over it already.

A tuned 991 TT needs 6.0 sec from 100-200 kph. If you get all out of the k16`s you can achieve 7.0 sec with modded wastegates. But the turbos will get lots of stress. Usually you reach around 7,8 seconds with k16`s.
So the time difference is for sure 1 sec. That is gigantic. Its impossible that a k16 can keep up with a 991 TT even without mods.

That said, if you can't see that his car is clearly a good bit more powerful than a run of the mill bolt on 6TT, you are blind.

Dynos are a tuning tool, not a concrete measure of performance. Different dynos and different conditions can produce vastly different numbers. I'd like to see some 1/4 mile traps from him done in a good DA. That would be better than a dyno or street race videos.

BTW, these are k24 modded with 49,5mm compressor wheels like the ones i have.

Without question.
Filters on turbo's made the single biggest "feel of the pants difference" to date.
The IPD plenum and 74mm tb are what finally made me run out of fuel. Before I installed them, my AFR's were happy in the mid 11's. After...I need to add to my fuel system. Clearly they made a big difference along the line too.

So intercoolers gain hp???
What you have done I think is awesome man. I'm just wondering what your numbers are.
