What do I want to do this for? Sorry, but I have a soft spot for the Palio. And for the people who do not know, they even did a Super 1600, which was raced in Brazil.
The NV has got a 1242cc 8v FIRE engine in a chassis that could be a little lighter. Nevermind, weight is something that always can be reduced.
No, I did not mean to strip it down to the core. It can be done in a subtle way by just removing bits that are not needed at all. And of those things are more than one would think.
Anyway, first things first. To start with the car was put back to what it would be coming from the factory. It was modyfied in so far that it was running a cng kit. Removing the CNG reduced the weight by nearly 10%, which was one reason less for the owner to complain about the performance of the car.
The car was treated a bit like a step child in more recent times. But this was not bad for one reason. It shows how much of a difference makes a good condition to a not so good condition.
To make statements it is necessary to see that the test conditions are constant. It is a long and expensive way to Bangalore, Coimbatore or Mumbai for dyno runs when the car enjoys life in Ahmedabad. So, a test strip was needed. Well, the roads around Ahmedabad make a good testing ground when no traffic is about. Of course it always have to be the same strip.
All done.
Testing starts.
The initial run after the cng kit came of was:
0~60: 7.5 sec
0~100: 21.54 sec
1/4 mile: 22.5 @ 103.31 kmph
This was the best run out of several runs
After an engine oil flush and oil change the following figures came about:
0~60: 6.4 sec
0~100: 21.5 sec
1/4 mile: 20.5 @ 99.3 kmph
The 1/4 time and the 0 to 60 time suggest a good improvement. Why it took the driver 1 second from 99.3 to 100kph I am not sure. However something is not right as the car still needs too much time from 60 to 100kph.
Next step was to fit an Air Intake Revision:
0~60: 5.4 sec
0~100: 19.49 sec
1/4mile: 20.488 @102 kmph
This slashed off 2 seconds from the 0 to 100 time. However, the 1/4 mile time suggest that there is still something not quite right.
To reach the target to have a sub 13 second time from 0 to 100kph we are a long way off, but we will get there. First we have to eliminate the causes of the poor times. These will be all accompanied by acceleration figures to give a good idea what impact changes do have on the performance of the engine and how performance can be gained with the least financial input.
Next step is changing the overdue ignition leads.
To be continued.
