It rises, it falls, it rises it falls. It's dynamic, it is always doing this. That's what boost control is there for. So it doesn't go too high or too low. Just because you don't understand doesn't mean it isn't happening.

Again WTF are you on about.
You don't need to explain the dynamics of a very basic closed loop (in some cases) control system to me.
All I am trying to get you to do is explain your original comment that the inlet pressure rises but boost stays the same.
They are the same thing, how is one increasing and the other staying the same?!

what do you know about electronic control systems you only do them for a living

You say you understand how a closed loop system works yet you cant understand how it works ?
So lets repeat the very simple statement I made. Can you read English ok ? Ive highlighted a key point in case you didnt go to Specsavers.
"It will raise inlet pressure....except the same pressure still controls the wastegate so boost will remain as normal

If I wanted a big power low lag 3dr, I would fit a ford 302 v8 with a standard bottom end and the appropriate head work and A cheap ebay gt40something turbo with quick spool valve in the boot.
500bhp and 500+lb/ft
Not an ideal solution for a car as clean and original as yours though...

OK..This thread really is a wind up. There is a very minor issue in that car is making over 1000bhp. So if you want it to behave like that, you too will need to make over 1000bhp.

And it sure as hell wont be low lag.
Maybe Fraser can help, seems he is a boost control wizard.

Cheers mate... That's probably the best answer you've come up with... Ask Fraser ... Cheers....
I understand mate... I'll just stuck with what I've got as I'm happy with it just I would have built a boost monster just to be different if it had been possible.

It is possible ( although perhaps not on pump fuel )...but it would be completely and utterly pointless. And a low power engine with lots of boost is not going to sound anything like the car in the video

What you want is a powerful car. But you have to remember you are still 2wd ( I assume ) so traction will be the biggest limiting factor if you do go down that route
The Golf in the video is 4wd.
You could easily build a setup that will smoke the tyres in most gears with ease and never go above 30psi.
If you just want a car that makes lots of noises, just build one with a decent turbo, slightly louder exhaust and maybe a screamer pipe from the wastegate.
But until it's making some decent power, it will always sound tame no matter how much boost it makes.
A low-moderate boost setup built as a high revving engine would probably make better noises for you, although low end will suffer a bit.
