26000rpm Beetle Burns out 1350hp

Published by on Aug 3rd, 2006, No Comments

This car has two engines: the production petrol engine in the front that drives the front wheels… and a jet engine in the back. Ron Patricks idea is that you drive around legally on the petrol engine and when you want to have some fun, you spin up the jet and get on the burner (you can start the jet while driving along) – OH YEAH!

The car was built because he wanted the wildest street-legal ride possible, and I think he’s achieved it. He was able to use some stuff he learned while getting his fancy engineering degree (a PhD in Mechanical Engineering from Stanford University) to design a street-legal jet car – something no one has done before.

“I don’t know how fast the car will go and probably never will. The car was built to thrill me, not kill me. But that doesn’t stop me from the occasional blast on the highway” Says Ron.

A police officer picks at his nose while trying to figure out what to charge Ron with. Notice the hopeful anticipation on the right – The California Department of Motor Vehicles does not anticipate such vehicles (who would) so the pigs out of luck. Hmmm, the car has two engines, technically making it a hybrid – maybe it can be driven in the commuter lane along with the Toyota Priuses?

Dynamism, Sportiness and Sophistication

Published by on Aug 2nd, 2006, No Comments

The Audi A3 holds an outstanding position in the premium compact class in South Africa. Now its top-of-the-range version is ready to go, the new Audi S3 boasting 265 bhp and quattro permanent four-wheel drive. Audi claims that with sparkling performance it pursues the ideal of pure driving pleasure coupled simultaneously with excellent everyday practicality – like all Audi S models apparantly do.

The S3 redefines the standards of its class – at the level of a sports car. The sprint to 100km/h is accomplished in 5.5 seconds – Aggressively hard-hitting, free-revving and with a sonorous acoustic profile, the powerful two-liter, turbocharged four-cylinder unit with FSI petrol direct injection proves to be a smooth, high-performance engine.

This power is transmitted by the six-speed gearbox and quattro permanent four-wheel drive to sweet 18″ rims. The new S sports suspension system on the S3 enables an extremely sporty driving style combined with comfort. This sporty compact model responds actively to steering movements, exhibits precise and safe handling characteristics and, thanks to quattro technology, enables maximum acceleration out of bends.

The dynamic potential of this three-door sports car is obvious at first glance. The single-frame grille sports chrome trim, the front skirt has a spoiler with large air-intakes and the side sills have been restyled too. There is a contrasting platinum grey diffuser built into the rear skirt, along with two S-style oval chrome tailpipes (mmm). Aluminium-look door mirrors and a body-colour roof spoiler give added impact to the visual statement of this baby. I wonder when it will hit the shores of South Africa?

VTEC & how it works

Published by on Aug 2nd, 2006, No Comments

Greetings, carbloggers. In this first automotive tech article, we’re going to take a closer look at the functioning of Honda’s VTEC system.

VTEC camshafts

Greetings, carbloggers. In this first automotive tech article, we’re going to take a closer look at the functioning of Honda’s VTEC system.

To start off with: as you know, there are 4 things that occur in a typical internal combustion engine: Suck, Squash, Bang, Blow. No, you haven’t logged onto dodgypornblog.com by mistake, although it might sound like it. Four strokes – intake (suck), compression (squash), combustion (bang) and exhaust (blow). On a given engine, power can be gained by modifications to any one of these strokes. There are many approaches to this, but today we’re concerned with the intake stroke. Specifically, Honda’s innovative approach called Variable valve Timing and lift Electronic Control – VTEC to you and me. Many other manufacturers have come up with equivalent systems, but Honda was the first (and probably still the best).

We all know that the more air you can get into your engine, the more fuel you can add to the mix, which means more torque, which in turn means more power. There are a number of ways to go about this. On atmospheric (naturally aspirated) engines, a common approach is to install more aggressive cams – however, the everyday driveability of the car tends to suffer (and fuel consumption goes to hell) as cam duration increases. Not a problem on the track, but this can get in the way when you just want to go pick up pizza and beer.

The VTEC system effectively combines two separate cam profiles in one engine, giving you the best of both worlds – a normal, comfortable drive when you’re buying groceries, but that can provide howling power when you want to scare people. DOHC VTEC was first introduced to the Japanese market in the 1989 Honda Integra, and then to the rest of the world in the Honda / Acura NSX a year later.

So how does it work? The fundamental component is the VTEC valvetrain. On both the intake and exhaust camshafts, for each pair of valves there are three lobes instead of the usual two. The two outer lobes have conservative profiles, while the middle one has a longer duration and higher lift. In the picture on the left, you can clearly see the additional cam lobe compared to a normal camshaft on the right.

During normal driving, the two smaller lobes each push against a valve rocker, which in turn causes its valve to open and close. The middle lobe pushes against a follower, shaped like a rocker, but this follower does not operate any valves. The cam profile utilized at this point is aimed at engine smoothness and fuel efficiency for regular driving.

Once a certain RPM point is reached, the fun begins – oil is pumped into a channel within the cylinder head, which pushes a pin through both valve rockers as well as the middle lobe follower, locking them together. This means that these rockers are no longer actuated by the regular cam lobes, but instead duplicate the motion of the middle cam follower, which is actuated by the middle cam lobe. The rockers therefore open and close their respective valves according to the new, more aggressive profile of the middle lobe. Exhaust and intake valves now open further and for longer, providing a significant power increase. Oh yeah. Once the revs fall below the VTEC threshold once more, the pin slides out from the rockers and follower, and the rockers are once again actuated directly by the smaller lobes, returning the engine to ‘normal’ mode.

Subsequent to the success of VTEC in their high-end DOHC engines, Honda introduced it on some of their midrange SOHC engines as well. However, in this case, the VTEC system is only present on intake valves, the exhaust valves retain the same timing and lift across the rev range.

There are three further variants out there – VTEC-E, 3-stage VTEC, and I-VTEC, but I won’t go into them now. If anyone wants more info, feel free to drop me an email.

For those who are curious, here is a list of VTEC equivalents from some other manufacturers:

  • Mitsubishi – MIVEC
  • Nissan – VVL
  • Porsche – Variocam Plus
  • Toyota – VVTL-i
  • BMW – Valvetronic

Petrol price up again! Argh!!

Published by on Aug 1st, 2006, No Comments

Many taxi commuters are expected to face a rude awakening as from Wednesday.

Motorists and taxi commuters alike will have to dig deep into their pockets as petrol hits the R7-a-litre mark.

Local taxi operations in and around Johannesburg are expected to hike their fares by anything from 50c to R2 a trip.

While the announcement was made last Monday, the word has spread slowly and many people are likely to be caught off-guard, said Hamilton Miya, spokesperson for the Witwatersrand African Taxi Association….

Renault allowed to use 'mass dampers'!

Published by on Aug 1st, 2006, No Comments

After the FIA banned the use of ‘mass damper’ systems for the Hockenheim GP, Renault have been given a reprieve until the official hearing by the appeal court.

Renault's Mass Damper system

Even though Renault have been using this particular ‘mass damper’ system since August last year, it was suddenly decided by Charlie Whiting that they were against regulation, even though the race stewards thought otherwise.

In order to prevent possible penalties, Renault had the system removed before racing in Hockenheim last weekend. After the race, they announced that although removal of the system had no direct affect on pace, it did affect the tyres, causing major blistering, resulting in Alonso and Fisichella finishing 5th and 6th respectively and dropping the Drivers Championship points gap to only 11. The Constructors Championship points gap is only sitting at 10.

Renault are keen to reintroduce the system, in an effort to prevent Ferrari from taking any more points away from their lead but their continued use of the dampers is not entirely risk-free however as Whiting said that he could only ‘recommend‘ to the court, which is an independent body, against taking any action.

“Tell us your most secret automobile desires – and we will fulfill them” is the selling point of . The company, renowned for tuning and modding high-end automobiles, dabbles in the tranformation of already amazing vehicles making them, uhh… better?

If one thinks of it logically… a R80k Citi Golf owner can plant a good R20k into his vehicle to make it better and unique. So why then can’t a R2m Ferrari 430 owner plant a good R400k into his vehicle to achieve the same uniqueness?

It’s all in preportion and fairness is the name of the game… I want one!
