The Revo (off road champion)







The South African built Revo is a perfect example of true innovation at it's finest.
It was built by, Achim Bergmann of Thompson Racing, for the Motorite Racing team.

The car is of a space frame construction with a fiberglass body. Tubing is 4130 cro-moly and uses a LS2 6l V8 engine coupled to a Sadev SC90 six speed sequential.

Shocks are American Radflo with secondary pistons in the coil-overs and an external bypass shock per corner. Wheel travel 300mm all round. A Works Bell Paddle Shifter NEO Universal is used to trigger up and down shifts controlled by a Motec M800.

A custom made dust seal was used to seal the paddle shifter from the extreme dust and moisture conditions encountered in off road racing. Up shift cuts ignition and pneumatically selects gear, down shift activates a pneumatic clutch, blips throttle and selects gear.. works very well.

This is Africa's first serious attempt at four-wheel drive Class A Special Vehicle. Power comes from an American built 500hp 6-litre engine and is delivered to all four BF Goodrich tyres via a 6-speed gearbox. Despite a serious air restrictor fitted to keep it in line with the other Class A entries it pulls strongly.

With so much torque on hand, ratios can be kept short but top speed is slightly limited when compared to some of the past competitors. A top speed of just over 180km/h is calculated, which might appear slow but trust me when you doing that off road and approaching a metre deep rut it is insanely fast.

Nigerian Armoured Vehicle





Nigerian Armoured Vehicle

A Nigerian made armoured car was on Thursday launched by President in this month of August 2009 at the eagle square in Abuja.

It is the first home made armoured car, with most of the materials used in its production sourced locally, while others were imported.

It was built by two Nigerian brothers who recently relocated from the United States of America. The brothers; Victor and Johnson Obasa, came back home to use their talent to boost security and also create employment in the country.

The brothers are based in Ekiti State and the duo own a company named Mobile Truck Technology where they nurtured and built the first Nigerian armoured car.

According to Johnson Obasa, the local production of the armoured car would help in upgrading the nation's security status. "It will promote up to 50 percent security in the country, it is something to protect the armoured personnel in their line of duty and it can work anywhere. It is designed to help the nation's security; we also did it to create employment," he said.

Also, Victor Obasa in a conversation with the press stated that they were in a better position to create this kind of cars since they are in Nigeria and understand the Nigerian terrain.

He added that they were willing to do it for the government at almost half the price of importing it. "We would do it for Nigerians for almost half the price they get it outside," he said.

The truck which was tested with different kinds of ammunition, from a far range had little or no mark left on it, but from a close range left peripheral marks.

On how they created such a truck with products from Nigeria, Johnson said: "It's been a little bit of up and down's. When we encountered some challenges, the Senate president encouraged us and at the end of the day we were able to put this together."

The other brother Victor pledged that they would produce a vehicle carrier that would meet international standard at a reasonable price.

The Minister of Federal Capital Territory, Adamu Aliero who represented the president at the launch said it was commendable that Nigerians with talents will come home and contribute to the nation's development.

He disclosed that the President had directed the Inspector General of Police to meet the fabricators on what they required to produce the vehicle to specification.

He also called on Nigerians within and outside the country with such talents to come out and contribute to the development of their country.

"This is also to call on other Nigerians with similar talents to also come back home and join us to contribute their own quota to the country and for other Nigerians with this kind of talent to put it to use," Mr. Aliero said.

Present at the event to inspect the vehicle were top police officers and the Minister for science amd Technology, Al-Hassan Zaku who said the ministry would send a team of engineers to the base where the truck was fabricated to further examine the product.

"We will examine it thoroughly and work with the police to ensure that it is properly produced to the standard they want," he said.

Cairo car.





Here is the work of the Technical and Vocational Institute at the Arab Academy (for Science and Technology and Maritime Transport) in Alexandria Egypt.

This is Egypt's first electric car project, entitled the Cairo car.

Serious research to develop and create localized technology towards producing a fine example of Egyptian ingenuity. This research is based on reverse engineering as well as self innovation to help achieve a national goal of a purely made in Egypt quality product. Its a 4 seater, and the platform has being successfully been tested. No details on the possibility of the Cairo car reaching production.

The Harper sports car





The Harper sports car. (South Africa)

The companies vision for building this car is as follows.

To produce a stylish, safe, fast, comfortable, fun, low maintenance sports car to be enjoyed on public roads and on the race track.

A one-make series will encourage owners to test their driver skills as cars will be placed against like for like engines. The key is: "Drive it to the track, Race it, Drive it home".

The specifications are as follows.

Power Plant

Engine: Mid mounted 4AGE 20 Valve 1600cc Toyota
Gearbox: Toyota 5/6 speed
Brakes: Toyota (disc all round with adjustable limiting valve for rear brakes)
Total Weight: 650kg

Power Output 120kw (160hp)
Engine Management: Gotech MFI
Performance Exhaust: TNT High performance branch and silencer
Construction: Mild steel space frame with composite non-stressed fibre glass bodywork

Although owners can choose from a range of transverse engines/gearbox, (eg; Honda VTEC, Nissan SR20DET, VW/Audi 20 Valve turbo etc), we recommend the Toyota 4AGE 20 valve engine for it's performance, reliability, low cost and availability.

The MENARA



The MENARA is MOROCCO'S answer to the executive sports car. Entirely made and built in Morocco to very high standards.

The MENARA is a harmonious mix of technology and classic automotive design.

Buttonwillow Summary





How was Buttonwillow? Great! More details to follow but in a nutshell:

Joe and Randal left the Snowspeeder home for this race and drove V-RAM with me. We were also joined by Dan Barnes, a friend of the Eyesores who we met at Thunderhill last winter.

Overheating was not resolved. The new water pump helped but we were still getting air in the cooling system. Saturday Randal rigged a weed killer spray bottle to our cooling system (little idea we borrowed from Eyesore) and strapped it into the cab. We could pump water into the system while driving down the front straight. It worked GREAT and we didn't overheat once on day two.

We stayed up until 1AM replacing our pogo-sticks with new struts. They were an immense improvement.

I rigged a cardboard radiator scoop that was surprisingly durable.

We melted our ignition coil Sunday afternoon leaving Joe dead on the track right in front of the observation tower.

(That's all I have time for now. Pics and more details to follow.)

Honk If You're Horny


After last week's rather destructive 'test' I borrowed Paul's welder and fabricated a rough but effective radiator mount.


We were at the junk yard for an ignition switch connector and I decide it was past time for a loud horn. We found two resonating pairs. I expected the conch shells from an 80's Saab to be loudest, but the pucks form a giant Mercedes literally rattle the whole car.

Three steps forward, ten steps back.

I had hoped for a successful test last weekend resulting in confirmation that the car is ready to roll. Instead we finished with more problems than we started with.

A subtle buzzing noise was agreed to be nothing to worry about. So I took it out for a spin.

First I drove into some giant ruts.

This bent the radiator mount and a fan shroud. Miraculously the radiator itself was unharmed, until we punctured it with a screwdriver while we tried to fix the shroud.

While assessing the damage I notice the subtle buzz was now quite distinct and smoke was coming from the timing belt cover. We had scored a FAIL on our timing belt job reassembly and part of the tension mechanism had fallen ad wedged between the lower cover and the belt.

FUHHHHHHHG!
