Apologies for my long absence from the forum.
Good effort!
But you are restricted by 2WD and no low range GB. Using power / momentum alone, is not the key. However a commendable effort from final year engineering students!
Congratulations!
You are absolutely right sir, glad you mentioned it. The present setup is good for softroad work and some highspeed trail driving only.
during offroading, even i felt the need for a crawler ratio, and a diff lock [especially while climbing steep slopes, where the present setup tends to cause wheelspin and the vehicle digs in]. and given the weight distribution of the vehicle, i believe addition of these two features alone without 4wd would do wonders to the vehicle's abilities. And a winch would ensure that you never get stuck.
Nevertheless, its quiet fun and challanging negotiating toughterrain using momentum and power and commonsense alone.
one plus point of the light weight was, that the vehicle's front end can be lifted by two people easily and the vehicle can be 'shuffled' to take a stuck wheel out of a rut.
emphasising more on the driving experience, the vehicle feels quiet peppy and agile. pulls away smartly in any gear, and there is very little wheelspin during a fullbore launch in 1st gear, as the knobbies dig in and grip pretty well.the gear ratios are taller than a stock maruti 800 (due to larger tyre diameter).
However, during fast offroad driving , it tends to run out of breath in 3rd and 4th gears. a shorter final drive should solve the issue, as will some old school power mods.
the front suspension is on the stiffer side, but the ride quality is descent as the driver is positioned almost in the centre of the wheelbase, reducing the amplitude of bumps effectively.
the steering's quiet light, and the handling would remind you of the early 'widowmaker' porsches. It understeers at first ( Ribbed front tyres would improve that) and then gently lets the tail out. Definitely not meant for the average joe drivers, and needs fast reflexes while driving fast. and also porsche driving rules apply (unless u want to have some fun). finish your braking before a corner, else be ready to go sideways.
Talking of brakes, the brake bias has been set towards the rear wheels, which have more traction by virtue of their tread design, and the weight distribution.
the long wheelbase makes the vehicle quiet stable in a straight line.
Although the vehicle is aggressive in nature, it is in no way uncontrollable.
Ive taken it for drives around my place, which includes terrains like loose-rocky mountains of the aravali range, some sand dunes, and some jungles with uneven patches of hard loose soil, plus a Dam. the vehicle negotiates the terrains with ease, although you have to keep some momentum for the tricky parts. have regularly taken 2 feet high jumps off a particular curb at speed . it comfortably climbed a 52 degree slope on the face of a dry dam using momentum (measured the angle using a gravitational angle finder)and was able to take a U-turn on the face of the slope. The only things missing are a Low range gear, a Diff lock , and a winch, addition of which would make it much more capable.
Another concern is the lack of articulation for the front wheels. Correct me if im wrong, but i think thats okay as articulation is required during off-roading to make sure the wheels stay in touch with ground and keep transferring the torque. But this being a Rwd vehicle, a wheel in the air during off-roading should't pose much of a problem ( except for steering traction maybe)
PS: fellow BHPians, please feel free to drop in for a drive dhawcash: Thats a great looking buggy.
You've made good use of the resources available.
How much did the whole project cost you?
The whole project cost us almost 80,000 bucks (only parts and machinary rental, as no outside labour was involved)
