On level ground 140 kmph may be top speed of Dicor. On a sloping stretch it could possibly exceed that by 20 kmph.

With 6 kms of road strecth that can be seen from your car and no traffic, we have easily achieved this with 5 adult +1 kid in the car and lots of luggage at rear and with a/c off.
I have heard of a few cases of tyre bursts in Tata Safari when braking from high speeds. The Bollywood actor Zulfi Sayyed comes to mind; he was doing 140 on the Mumbai-Pune Expressway, saw a cow on the road near Bhatan tunnel, braked hard and rear tyre burst. The Safari went off the road and he was thrown out, but miraculously he landed on grass and survived.

As you say, it is better not to hit those speeds when the SUV is fully loaded. But if you must, you should preferrably over-inflate the tyres (by maybe 3-5 psi?).

What say others
The Mumbai-Pune Expressway is the next best thing to a test track. But it is not always safe to speed on the Expressway and one must know when to slow down.

I disagree with the part that the expressway is the next best thing to a test track.

The expressway has a very rough and bumpy surface and that takes away the fun. Also the few bridges have tar while the road is cemented and lots of ups and downs and repairs have taken toll of the road.

It aint fun driving there now. Add to that animals that might come out of any bush and create a potentially explosive situation.

I agree with N_C. No public road should be considered as a test track.

You can stretch your car but as long as your sure of the road and there's no traffic for a long way ahead.

I remember the Ahmedabad-Baroda expressway NE1. If you want to stretch your car to it's capability then that's the road. Dead straight 3 lanes and less traffic with no stray animals and well marked signs all over.

Currently in bangalore the NICE road is a testing track but there have been incidents there as well. The road has not been opened to public officially.

Even the NICE road is quite uneven and bumpy. I'm talking about the stretch from mysore road point. Maybe the final layer of tar has not been applied yet. And if you are in a car like OHC, which tends to give you a floating feeling at high speeds, you will not the have the confidence to push it to the limit.

A test track is the best, but there is not one which is near bangalore.

I have done 170+ on my Esteem Vxi (2005), which was added with Power boosters. This was on the NICE road just after entering it from Bannerghatta road. There were 5 of us with AC Off.

Awesome, thanks for the reply, for the Fiesta.

i had done 130 on my m800 on delhi highway. i was lucky enough that i slow down before the cops having those speed measuring devices.

Tyre pressure increases as the car starts moving because of heat that is generated.So if you overinflate the tyres by say 3 to 5 psi would it not lead to the tyre pressure in heated condition being even more and lead to a tyre burst specially in cars like safari where the overall weight of the car is around 2 tons so the road resistance will be more and hence the heatbuild up in the tyres will be more than say a car like an 800?
Just a question

The reason why it is recommended to increase the tyre pressure on highways is because the little higher pressure reduces the side-wall flex and that reduces the friction and hence less heat build-up. But I think +5 psi is a bit too much.

How helpful was the Power Boosters and what is it?

Can it?

and Safari Dicor 3L can do 160kmph? Steer! can you confirm it please.

@harry; is it a 5 Speed ?

Also note that Pavan Kadam wanted to hit 160 kmph with the Safari fully loaded. The tyre pressures should surely be increased, but precisely how much may depend on the manufacturer's recommendation and the tyre manufacturer's maximum pressure. That is why I had a question mark against my "3-5 psi". Generally you can go up to 10% less than the trye manufacturer's maximum marked on the tyre, as per the carbibles website; i.e., if the maximum is 44 psi, you can go up to ~39 psi. But of course, that may not be advisable at all on our roads.

@humyum, the car manufacturer's recommendation is the cold tyre pressure. Of course the tyre pressures will increase under running, but that does not mean that the cold tyre pressures should be reduced. For sustained high speed driving with full load, increase of the cold tyre pressures would be desirable as pointed out above.

210 on a stock Corolla, means massive speedo error.

RD at 165, not normally, but I've seen that user ID on RDDreams, so I wouldn't put it past him.
