Just Bought An Xr6T

[Doddo22]

nice you got pics? I picked up a mkii for 10500 a few weeks ago, took me ages of trawling carsales, gumtree to find one with everything I wanted within my price range. 6 speed box was a must

[xrlook]

About 2-3rpm it starts to kick in mate:/

Once u get the car tuned,( if u do) u will feel the turbo kick in and the are move like a dog shot in the Arse

[_Velocity_]

Yeah about 2500 rpm it will kick in.

Nice upgrade from the VS bombadore!

Maybe get it serviced and get the turbo bolts torqued up if you feel it's underpowered.

Turbocharger is running all the time even at idle, but it is at a certain RPM that it begins delivering enough air to the engine where you begin to feel extra acceleration, that is because the Turbocharger is powered by the exhaust gasses so the higher the RPM, the faster the turbo spins depending on how much load there is.

They are Nice cars the XR6 Turbos, you can have heaps of power and still have it drive like stock standard.

As Boris mentioned above "depending on load" is the important part for you to notice Falcon Mad, as it's not linear like a supercharger. Turbos are self feeding and generally only stopped by either restricting air intake (throttle) or dumping already existing boost levels (wastegate). The more it spins -> the more it feeds the engine -> the more exhaust gas there is -> the faster it spins -> the more it feeds the engine etc etc...power ramps up quickly by mid engine RPM and you get the sudden turbo rush feeling!

Release the throttle a tiny bit though and the car dumps that boost out using the wastegate and bye bye power, start again. Superchargers boost levels on the other hand are tied directly to engine RPM, making power linearly. Same power at given RPM regardless of what you were doing a second before. Not as much of a "rush" but more a constant shove in the seat. Often easier to put power down without spinning the wheels because of this. I find the rush very, very addictive.

Once RPM climbs the turbo needs to be good enough to maintain decent PSI levels as the engine can make use of more air. Too small and the turbo runs out of puff at higher RPM. Too big and you end up waiting ages for it to spin up (spool) in the first place.

We have the major advantage over the imports of a 4L displacement as compared to 2L, 3L etc. More gas in engine cylinders at any given time helps spin the turbo sooner, and the Barra is an engine with a long stroke that makes great torque even off boost. Easy to drive and makes huge torque from low RPM all the way up!
