Matthew, A few comments here: Autos can be good on a turbo car (from a dead stop) because the driver is able to power brake the engine to build boost. This results in a full boost launch from low-RPM which is where the torque curve is nice and fat. While I'm not a huge fan of the Vortex lately, this thread actually has some good info and few flames: http://forums.vwvortex.com/zerothread?id=33057
Another note: to my knowledge, the wastegate does not vent exhaust gasses back into the intake tract, that is the function of the bypass valve, or "diverter valve" in 1.8T language. The wastegate is used to control the turbo's RPM's by allowing more/less exhaust gas to flow past the turbocharger's impeller. It allows the car to regulate the amount of boost provided. -Brett.

I know there was a thread with his name in it, but I don't recall the outcome.... one possibility, his addy was a ML.com domain, perhaps it was a work account that's no longer accessible? Let us hope that's the case! --- Matthew Yip <[email protected]> wrote: > I don't have conclusive proof but it makes sense that the automatic > is faster, especially with a turbo.
