Indian Rally: Stage Speeds

Tom · 10th August 2004, 17:52

I dont get it

.
Naren Kumar was qouted by TOI that on the stage 'Banda' he could touch 200kph and on that stage (4.7kms) he averaged 137kph (MAI allows only 110kph) and hence the stage was cancelled.

I dont undertsand...WRC cars barely manage top speed of 200-220 on stages. How do the Balenos go so fast?
Will someone *

explain

cheers!

What i feel is that WRC cars have very short ratios which are designed to help the car, accelerate much faster than it would have, in stock form.

Since speeds of over 220 cannot be touched regularly and the fact that it's not safe in any way, teams might have concentrated more on the acceleration, rather than outright top speed.

While a regular 300 bhp street car can easily hit speeds of 260+ kmph, the WRC version might be able to manage 220-230kmph max. But what the WRC cars can do, is that they can accelerate from 0-100kmph in under 3.5 secs.

It makes more sense doesn't it. Why have a car that can do 260 when there's no place to do it. If the INRC Baleno was to be tuned to max out at 160-170 kmph with the ability to accelerate faster, it would have produced much faster times through the stages.

true. but im talking about handling the car on special stages at those speeds.
WRC = state of the art technology.

also werent the baleno's supposed to be using some new short ratio gear box?
also the ave time of 137kph is rocking man!
does anyone have the stage times for the Banda round?

Shan2nu · 10th August 2004, 18:59

Yup, averaging at 137kmph is pretty good. Which means that he would have covered the 4.7 km stage in around 2mins and 03 secs. Which brings another doubt to my mind, how long does it take a INRC Baleno to hit 200kmph on the kind of surface they were racing on???

A stock Baleno takes close to 38-40 secs to hit 160kmph, in a straight line, on tarmac. The question is, did the 4.7 km stage have a straight, long enough for the Baleno to hit 200kmph and, was that 2min 3sec time enought for it to hit 200

BTW, where did TOI get hold of that 200kmph stunt Narain pulled out??? Did they use a lazer or GPS device to test it or was it the speedo inticated speed??

A Baleno doin 200kmph on a 4.7 km stage that lasted 2min?? I have my doubts...........

yes shan2 this is what has been lingering in my mind for past 2 days.
4.7kms in 2.03min

I have in-car videos of WRC cars pulling 215kph and believe it takes bloody long time man.

TOI qouted Naren saying he culd touch 200kph.

If i was workin for TOI, i wouldn't have even bothered to print that. From what i've heard, INRC Vtecs used to manage around 170-175 kmph, which is much more believable.

200kmph is way out of line, even for a Vtec.

What is the claimed BHP figures for stock Baleno?

Last week at the 2004 Rally of Finlad which is considered one of the fastest of the championship, Petter Solberg set a new world record for the highest ave speed on a stage = 130.3kph

He should switch to the Baleno

Tom · 11th August 2004, 12:25

Let say the Group N Baleno with shorter gear ratio's culd touch 200kph on the satges...then it's fair to assume that it's max top speed is around 220kph.
Then say they have a Group A Baleno with longer gear ratio's for top speed.....will the top speeds be in excess of 270-280kph?

We're talking about apprx 150BHP with no turbo charging

A 150bhp NA Baleno should touch 200kmph if the ratios are perfect. Whether it will hit 270-280kmph with longer gears, depends on many other factors.

What happens is that after a certain speed, wind resistance begins to take it's toll on the engine. Now the engine, has to not only fight frictional resistance but also the resistance offered by air.

Technically, it's possible for a 150bhp Baleno to hit 270kmph but when this is put to practice, i don't think the Baleno could manage anything more than 250kmph.

A 150bhp Baleno engine can surely hit 270kmph provided, it's fitted onto a bike.

well guys, on the day the stage was cancelled, one of the marshalls told me that they were completing the stages in less than 2 minutes.

What sort of a stage was it? If it had very fast and long turns, then i can believe the 137kmph ave speed. I myself, have averaged at 108.8 kmph over a distance of 135 kms without going beyond 140kmph, but remember that this was on a NH with smooth Tarmac.

killjoy · 13th August 2004, 13:16

well the stage was very similar though not as wide as a NH

after the sweeper went by, me and another friend were driving the stage and we were touching 130, so....
