Tuning the Toyota Supra

The Toyota Supra is one of the most impressive production cars in terms of its tuning capabilities. It would appear that the engineers created an engine that were suitable of handling 600 BHP. The final power output of the engine know was reduced to around 350 breach BHP due to pressure from executives who didn't want to be accused of releasing an uneconomical and dangerously powerful car.

Quite simply with a minimal outlay you can produce one of the fastest cars on the road. The first thing you should look at is a the turbo, many Supra owners opted for a larger turbo which increases the mid and high range output of the engine. Select a turbo with a ball bearing rather than a thrust appearing as the spool up quicker, and last longer.

The next step of the tuning project involves the sports computer which manages all aspects of engine timing and boost. With the simple modifications you could be looking at power gains of double your starting baseline. See torquecars for more index tuning advice on the Toyota Supra and the benefits and drawbacks of the many different types of modification on offer.

BMW M1 30th Anniversary

Thirty years ago, at the 1978 Paris Motor Show, BMW Division presented its first ever creation and at the same time, the Bavarian carmakers first and last mid-engine supercar, the M1. Designed by Giorgetto Giugiaro and developed in association with Lamborghin, the M1 was initially intended for the racetrack.The road going edition was equipped with a naturally aspirated 3.5-liter straight 6

Biofuels good bad or ugly?

Biofuel has been hailed by many as the answer to our dependence on oil. A bio fuel is one which can be produced from biological matter. The theory is that the fuel crop grows and absorbs Co2 and then it is processed, turned into fuel and burnt in our engines.

Biodiesel is popular with some people starting to produce their own bio-diesel at home with kits. The nearest you can get to petrol is ethanol which is a form of alcohol but a petrol engine needs extensive modification to reliably use ethanol. The latest thinking is that a small percentage of our petrol can harmlessly contain ethanol and this will reduce oil dependence by 10-20% a year for the average motorist.

The downsides though which are some what ignored.
  1. Damage to engines. Ethanol engines are different to petrol one due in part to the corrosive nature of ethanol within an engine. Even a watered down mix will potentially cause damage to an engine, research is currently being conducted into this assertion but the early indicators are not good. Ethanol is also hydroscopic meaning it absorbs water easily so it will mean the average driver without a permenantly full tank will have fuel and water pumping into his engine.
  2. Ethanol is difficult to produce and requires a great deal of energy for the distillation/filtration and processing. We seem to be robbing Peter to pay Paul.
  3. Ethanol produces less energy per equivalent volume of petrol. This means that our fuel consumption/gas mileage is reduced and we end up burning a greater volume of fuel.
  4. Modern diesel engines are not happy to run on unprocessed vegetable oil and again there is an energy overhead in the conversion/manufacturing process.
  5. Crop space is taken up producing fuel crops instead of food crops. This could impact on farming and food production. Where new land is ploughed and used the trapped Co2 in that virgin land is now released into the enviroment.

We clearly need more research into bio-fuels and their future impact before we start switching over to use them. Bio Fuel can only ever be a partial solution to the problem. Our consumer led lifestyles have more impact on Co2 than even a high mileage drivers car emissions. The UK are potential going to introduce compulsory introduction of bio/mineral fuel blends at all pumps. This has already been a policy in the USA and already lobbyists are calling for a reversal of this misguided attempt to save the environment.

The future of tuning?

The new Nissan GTR is certainly turning some heads. It would appear that the gadgets and wizardry that make the car work can perform magic.

We are talking supreme levels of traction and power throughout the rev range. Despite it gargantuan size it handles like a car half its weight. The Nissan R&D boys have turned out something special. The car at is stands is a very complete package. However there is a down side for the car tuner.

To produce such amazing power levels the car has been hardwired to resist tuning. The GTR contains one of the most anti tuning and aftermarket modification defence array we have ever seen. This step was taken to placate the Japanese authorities that the car would not become a 1000bhp monster like the previous incarnations of the Skyline in the hands of Japans premier tuners.

The main ECU is pretty damn hard to open and reprogram due to encryption. Further to this the car has accelerometers and GPS receivers and it is able to work out if the car is faster than it was designed to be. So too much acceleration, faster cornering or sharper braking all trigger the "anti mod" warning, invalidating your warranty at best and at worst the car will start to protest.

This is only the surface, try fitting larger wheels and you again hit the anti tuning defense grid. The speed is also restricted unless the GPS pinpoints your location to a Nissan Recognised track so the car will actually police your speed limit depending on where you are.

I'm sure that many tuners will find ways around all of this and I can't wait to see what extra power and performance can be extracted from this monster. I know the guys at TorqueCars are keenly watching and waiting for updates. This does show the car makers attitude to car customisation and personalisation and it is certainly a worrying trend in automotive design.

Hitting a pheasant - not very pleasant.

Driving along the motorway the other day I noticed an abnormally large number of pheasant corpses lining the road side. To be honest I didn't really pay too much attention - its just one of those things you notice when something happens.

At cruising speed there is not a lot you can do when something decides to take a Kamikaze run at you. I saw a Pheasant sitting in the central reservation, he seemed to have happily negotiated a busy carriageway of oncoming cars and I imagine his Pheasant friends were egging him on to go the whole way.

It then looked up at me and when it decided was the most optimum moment for a Lemming like run it went for it. Although I jammed on the brakes I sadly hit the bird killing it outright.

Then you start to analyse what happened after the event. It was a bird that I hit. Hang on a minute birds are meant to fly? What was up with this pheasant and I assume all of the other pheasants lining the roadside? Was it some kind of suicide pact? Was it a lemming copycat flock of pheasants? I guess I will never know but I have a cracked number plate and small dent to remind me of this brave little bird that went for it.

The ricer or Racer test.

Ricers are those kids who know little about style and subscribe to the "if it makes more noise it must be faster" philospophy. Although Typically aimed at Japansese cars the word has evolved to apply to any kind of tastlessly modified car.

The racer is the ultimate car enthusiast who drives with skill on our roads and only goes fast and pushes the limits on a race track. There are of course many categories in between but this survey will help to identify which classificiation you fall into.

http://www.torquecars.com/tools/racer-ricer-test.php

Here is what I got - do let me know what your results are using the feedback section.

The Track day Racer
Congratulations you are officially a Track Day Racer. You shun all things glossy and shiny. You know a lot about tuning and performance cars. You would rather have a standard looking car with a highly tuned engine than drive anything that shouts "look at me!" You accept breakdowns and component failures as the price of trailblazing the cutting edge of car ownership.
Your average weekend will be spend underneath the car tweaking the suspension and tuning up the engine. Alternatively you will always attempt to be the first away at the lights, but only if you are up against something that looks it might be a challenge!

You have the reflexes and driving skills of a pro driver.

Because of your responses to the survey we can make the following, more detailed comments.

You are welcome to join TorqueCars as you enjoy many aspects of cars and driving. You can join here www.torquecars.com/forums/ We feel that you would have a lot to contribute to our tuning forums and will certainly learn a lot. You do not enjoy general chat forums so our car specific topics are where you will spend most of your time.

We are sure you will appreciate our mpg calculator so you can now quote your exact fuel consumption and see how much you can save in fuel prices! You will also appreciate the fuel saving tuning and driving tips we have in our main articles section. You are the type of person who expects to get what they pay for. Quality over quanity is your mantra so have a read in our styling section and see which mods would be the most worthwhile. www.torquecars.com/styling/. Our articles will help you to avoid making mistakes and purchasing the wrong modifications.

This personality profile report for you demonstrates that your main focus is on speed and performance. There is a lot more to driving than going fast in a straight line. When you learn to take the corners you will achieve a higher place of driving Zen. Perhaps you should look into drifting or track day driving rather than the drag strip.

The pitfalls of car tuning.

Car tuning has become more than a popular hobby it has become a multi $1,000,000 industry. There is no shortage of parts available for every conceivable make and model of car. Sadly though many of the manufacturers' claims are far from the truth. A common ruse used by the car manufacturers is to show the performance gains of their products fitted to a high performance engine. On a 300 BHP car the parts may well deliver a power increase of 30 BHP but on a much smaller engine car producing just 76 BHP you would not be able to see a power gain in excess of a few BHP.

The problem there is more serious than this as some performance parts can actually reduce the performance of a car. At the very least the car ceases to become usable into normal everyday driving conditions. Tuning a car for the use on track is very different to tune in a car that is going to be a daily run around.

In everyday use you need a good balance of economy and reliability along with the performance gain. Four track use, reliability is not so much of an issue, as the car will typically be stripped down and rebuilt after each race, or a few times in each race season. The track car will also spend most of its life in the upper Rev band where most of the power gains are. An everyday car will spend most of its time in the low power band and will be moving slowly so heat buildup is to be avoided.

It's for these reasons that I started writing car tuning articles and posted them on TorqueCars. Having spent a lot of money tuning up a car I quickly learned that many performance parts were not performance enhancing and actually reduced my enjoyment of the car. TorqueCars take a look at the many advantages, disadvantages and benefits of each type of modification. Before buying a performance parts or modifying your car I would strongly recommend that you read some of the articles on TorqueCars and at least be a well informed purchaser.
