Peugeot 207 Turbo uses a Twin-Scroll Turbocharger

Plex

I have been reading this article from this worldcarfans.com

Interesting to see this improvements for the Peugeot 207. I have copied out an extract.

Here are the extract.

Twin-Scroll Turbocharger, A First In This Category � Reduces Turbo Lag
This is the first time that a Twin-Scroll turbocharger has been used on an engine o f this displacement.

As the name "Twin-Scroll" suggests, the exhaust ports in the cylinder head are first and foremost grouped in pairs ("twinned") in the exhaust mani fold and the turbocharger.This therefore combines the exhaust gases exiting from cylinders 1 and 4 and from cylinders 2 and 3. These two columns o f �pulsating� exhaust gas arrive in "scrolls" whose combined flow drives the turbo charger�s �turbine� to provide the maximum possible boost.

This separating o f the exhaust gases as they enter the turbo charger improves the efficiency o f the flow o f the gases and maximises the available energy to drive the turbo charger �turbine�. The result is a remarkably responsive engine, as it starts to boost from only 1000 rpm. The turbo lag or response time, frequently criticised on turbocharged petrol engines, is therefore drastically reduced.

The flow o f exhaust gases can accelerate the turbo charger �turbine� up to a speed o f 220,000 rpm. It simultaneously drives the �compressor� which pressurises the air entering the engine.The maximum turbo charger pressure is limited to 0.8 bars by the turbo charger waste gate.

This engine was built by both PSA & BMW. Most production turbo pugs are diesel. This is the first petrol turbo pug built. I am wondering how extreme this baby can go.. Twisted Evil

i cannot wait to see if future aftermarket products will be in production for this Pug. I guess time will tell.

They are using the EW10 for the rally version (S2000) as they can't use the EP6 cause its built by PSA AND BMW

oh the EW10 engines, saw a web site that is offerring aftermarket parts for this engine..

but for a 1.6 doing 175bhp thats good..

i am glad to see peugeot is getting into turbo gas engines.

Well actually they're getting BACK into turbocharged gas engines.
