power steering lighter in Indica Xeta than in Turbo
Drove a friend's xeta, and got noticed how light the controls feel. The lighter clutch I can understand, same of the much better feel of the gearbox, but the power steering was substantially lighter. how can the feel of a power steering change with the engine type?
Is it because of the 14" wheels i have ( xeta has 13")
is it because of the weight of the diesel engine ?
or do i need to get my steering checked ?

Why don't you try another model similar to yours?
I don't feel the power steering in my Marina is heavy!

The petrol's steering does feel lighter - no cause for worry unless you find your car's steering heavier than another turbo's.

Probably the same PS unit serves both the Xeta and the Diesels. With the Xeta's lighter engine (especially the 1.2 GLE, GLS and GLG) and smaller 13" wheels, there will certainly be a perceptible difference.

I have an Indica Xeta 1.2L GLS.
Recently I noticed that when I turn the steering towards the extreme right or left sides, I hear a motorised sound and the engine RPM dips down to about 400 to 500 RPMs. This thing happens till the time I hold the steering in one of the extreme directions (completely left or right).
I don't think there's anything wrong with my power steering. Was just wondering if someone well versed with the wonderful Tata Motors engineering could explain the phenomenon to me??

You are right. You can hear this phenomenon on any Hydraulic assisted power steering vehicle. When the steering system reaches the extremes, the hydraulic valves are at full open condition during which the assisting system let oil at its maximum flow rate. Since the steering system has reached its limits and cant move further, the pressure built by the Hydrauic pump reaches the maximum to crack open the pressure relief valve inside the pump.
This means that the pump operates at the maximum pressure condition and zero output flow. All the pumped oil is returned back to the reservoir. Engine feels as an over load due to the overload on the pump.
Finally this sound and fall in engine RPM is no harm either to the pump or to the engine. The ECU controlled engines immediately stabile to the idle RPM as soon as the RPM falls down due to the pump over loading.
Nothing to worry about this and enjoy your ride.

A noteworthy point.. The hydraulic steering does feel a lot lighter at high speeds and I must add that this kinda scared me during my drive back to Pune from Baroda on NH8..
Anything wrong or its just the high speed?
BTW: I was clocking only around 120Kmph
