Firstly I would like to introduce my organization TINSI Race Cars. TINSI is an organization which was started by me and my friend Gopal with a vision to bring racing into the mainline automotive Research and Development in India.

Right now racing is nothing but another way to kill money. And I am not speaking in air, I have heard these statements from people in the racing fraternity in India. And how can it not be true. What are Indian race cars, or the dashing modifications of Indian road cars doing any way. Are they making any contribution to the Indian Automotive Industry. No

So that means,whatever is going into racing is a dead investment. What is the return on this investment anyways. Thrill and fun??, that’s it.

Well racing is for something beyond that. The kind of data and information that it can provide can help in road car design and development and can help in making the road cars safer and better in handling. I may not be a very reliable source of information here, so it will be better to read about companies like Mclaren, Ferrari, and their take on racing. Mahindra with the introduction of Mahindra Racing has also come forward with the same ideology, which is a wonderful step.

What you see below is technically a Mahindra CJ500

It used to look like this before

However we have done the following upgradations to it: -
1. Design, fabrication and installation of off-roading four bar link suspensions with panhard bar and coils springs on both the axles
2. Installation of disc brakes on all four wheels (by removing the stock drum brakes)
3. 31x10.5 in tyres
4. Rear roll structure
5. Minor changes like bucket seats, steering wheel etc

It was our first step towards working on an off-roading vehicle and understanding its requirements. Can never say that we have fully accomplished that, but we have tried our level best to work out the best suspension configuration possible, through a number of iterations and simulations.

All the structural components of the suspensions and other systems that we have fabricated have been analysed using FEA techniques to ensure strength and hence safety under immense off-roading conditions.

Now we are in the drive testing phase of our vehicle which we very dearly call TINSI Inferno.

Last week we took it on a drive to Ayodhya which is a very historical place and around 20 kms from our place. It was a wonderful experience.

The roads of UP at certain points provided us a very good mild off-roading terrain for initial testing phase and we were very happy with the results .

The handling at fairly high speeds of 70-80 km/h was really good. The roll parameters that we implemented seemed to be working fine and the vehicle was very responsive to steering inputs. The pick up and cruising was very smooth. It did had a little jeep thing in it, but it was nice.

It was an eye candy on the streets. A head turner. It was a lovely experience with it.

We were really blushing when a young kid walked upto us to ask if it’s a Mini Monster Truck. We told him that its not, not even near to such wonderful piece of engineering, and maybe someday we will try to attempt that. It’s a dream.

Mahindra CJ500 with coilover suspension. EDIT: Rover V8 engine coming up-dsc_0078_resized.jpg

As of now, we have some further work to be done on Inferno.
a. To eliminate bump steer.
b. Tryout other springs ,dampers with other specs.

Inferno is the best subject on which we can experiment and learn more about suspension parameters and its effects on handling.

Mahindra CJ500 with coilover suspension. EDIT: Rover V8 engine coming up-dsc_0021_resized.jpg

Hope you all like Inferno. Please post your views on the same. It will be very encouraging for us.

This is quite an interesting build, where did you source the parts for suspension mods etc? Or was it all manufactured locally? Some more details regarding the modification would help, as well as picture.

What kind of articulation does the vehicle have with these mods?

This is a very interesting modification. While the suspension looks very useful for offroading, I am puzzled that it comes by sacrificing 4x4 ability.

Are you planning to add the 4WD back in the next phase? Does the design allow for it?

Most of the suspension parts were manufactured in-house by us. Like the following
1. Suspension links
2. Panhard Bars
3. Coil Springs
4. Suspension mounting brackets for the chassis and axles
5. Shock absorber assembly mount on the chassis
etc

Will soon upload more pictures, specially on articulation

We will be making it 4x4. Thats important for us. This jeep was without a front differential initially, and we didn't put one as we were unable to find the transfer case and front differential assembly.

However, we will put it soon.

In the next phase we are planning to put a 3.5L Range Rover V8 1988 in it. But that will take time, as we will have to restore the V8 engine that we are having. We will have to import transmission and differentials for the same.

Right now we don't want to put this engine, also because we are driving the jeep a lot on highways and a lot of people are taking test drives. With this engine it will be very expensive as it drinks fuel like anything.

Here is a small video that we shot while enjoying a little off-roading experience in INFERNO. Will upload a longer and better video soon.

Default Rover 3.9L EFI V8 engine for a Mahindra CJ500

Hi BHPians,

Its a pleasure to share with you a task that we are highly excited about. We are going to put a Rover 3.9L EFI V8 engine into our CJ500 Jeep, about which I have already shared in my previous post (CJ500 with coilover suspensions).

Its going to take some time, as we are still awaiting a transfer case for the LT77 gear box that we have coupled with this engine.

Would love to have views from you guys on this.

That engine looks delicious! I've always wondered why we don't see Jeeps with more powerful engines, when there are so many successful swaps abroad. Your Jeep is going to be a heck of an experiment. Looking forward to the final outcome, especially a video.

Which transfer case? Are you sourcing it from the UK or did you get lucky with a salvage car in India?

Good luck!
