Is it a squirrel? Or some sort of exotic bird? Noooo it´s a freakin IMSA GTO :D

Used to love watching the Westbank Modifieds from Kyalami during the late 80's and into early 90's with Sarel van der Merwe at the front most of the time..Awesome piece of automotive engineering.

from a distance the waste gate sounds like wildlife in a rainforest.

Saw this car in the early-to-mid 1990s race at tracks in South Africa, Kyalami, Zwatkops, East London, Killarney, Welkom....it was a monster...this video does not justify the sheer joy I experienced when it came rushing past the pit wall, mere meters away from where I would stand and spectate....it was pure bliss....the regular pilots were Terry Moss and Chris Aberdein...heros😍

It is the missing diverter valve (Schubumluftventil) in those race engines. In serial production cars it reduces pressure from turbo to combustion chamber when you step off the gas. When it is missing in race cars, the pressure against the turbo leads to deceleration of the tubine shaft and the pulsation causes this flutter sound. Look at engine bay pics from rally audis, they still have wategates.

This car and it's sister were built in South Africa by Audi Motorsport. They were driven by Terry Moss and Chris Aberdien.

It was a new car, compared to the 90.. but it still somehow featured and engine, with 85% in front of the front-axle. Giving it problematic driving abilities.. nonetheless it won because of the incredible power from the 2,2 litre engine. 325 hp per liter... that's quite amazing. While the Mazda with the 13b triple rotor actually stood up to it, with rotary power.. The sound must've been unbelievable

How do you make your car sound like bird and chirp it's not a bov and it's not fluttering or turbo surge can someone please explain running prototype components on these engines design by engineers For rally racing not off the shells parts or aftermarkets it's like true ALS anti-lag where you take the fresh air from the intake and dump it back in your exhaust manifold to keep your turbo spinning that's where you get the loud bangs and pops now can somebody please explain to me how do you get the bird chirping sound

I've been told that when they let off, the throttle plate snaps shut sending the air back through the turbo. How it sounds like this, I do not know. I don't even know if this is factual. I've just been told this a couple times.

It is turbo flutter, if you want to recreate it then you need to copy the intake design as that is the main part that changes the sound, generally these cars just ran the air filter bolted to the turbo.

Turbo fluttering does "STUTUTUTUTUTU" when you stop pressing the gas. A bov does "PSSSHHHHHHHHHHHH" when you stop pressing the gas. A wastegate does a sound but when you are pressing the gas

so some cars have both wastegate and turbo flutter or both wastegate and bov.But whats the turvo fluttering?is that happens when you dont put a blow off valve in your turbo?

@EmilienGosselin

7 жыл бұрын

That's right. When you are accelerating, you are building up pressure in your intake manifold (between the engine and the turbo). The problem is that when you stop pressing the gas, the throttle body closes so the pressurised air has no way to go. This is the purpose of the bov. When you don't have a bov, the air is going back to the turbo while the blades are spinning (the blades feed air into the manifold but the air is going back at the same time) thus making the stutututtu sound

Fluttering because there is no blow off valve. When you don't have a blow off valvve, the air is going back to the turbo while the blades are spinning (the blades feed air into the manifold but the air is going back at the same time) thus making the stutututtu sound...
