turbo chatter

[doski]

yea the chattering sound is the sound of the turbo goin into reverse but they can afford to rebuild it after every couple of rallies to repair the damage

On a rally car the turbo don't go in reverse. They have antilag which keeps the turbo spinning at full speed. Thats why they last 10 miles. They glow white as they're on full spin for so long.

Anti lag is done by seriously retarding the timing and injector a load of fuel so that it burns inside the turbo...

yea i was going to say that rally cars turbo's don't go in reversen that would completely defeat the object of anti lag

yeh als alters the ecu settings to fire fuel down the hot manafold on the exhaust stroke ( hot fuel hitting hot manafold ,igniting , spiining turbo faster on decelleration, ready for acceleration , fast skittle sound > turbo simple

dear o dear im drubnk!?

the chattering sound is the metal flap on the turbo right.....when the air is coming out. im sure thats right.


thats what we were told when a mates cossie was set up.

No its the air stalling the compressor blades. As basically the compressed charge reverses back out of the turbo.

It causes stress on the shaft as a result. I personally wouldnt bother with a dump valve under 20psi. There arent many on the market which do a good job anyway, most are designed to be loud.
