News – The 2008 Skyline GTR
Nissan engineers have been hard at work at the Nurburg Ring testing the all new Skyline GTR. Spy pics have emerged of the skyline doing battle with a 911 Turbo at the Ring. The GTR apparently lapping the ring 2 seconds faster than the 911’s reported famed run of a 7:40. The one being tested was the entry level in a reported 3 tier model line-up boosting 360Kw. The range topping EVO Spec is believed to be a 395Kw lighter weight edition to sell for about 650K. Due to make its debut at the 2007 Tokyo Motor Show later this month pre-orders have already begun in Japan. Let the TOUGE battles begin.
Looks like Audi are benefiting from the V10 lump they procured from Lamborghini. This has to be the fourth model using it. This time it’s in supercar territory. The RS6 bolts out a massive 426Kw to take on Mercs AMG 65 range head on. Unfortunately its Bavarian cousin is out of this battle with no model in that power range. The 100km/h dash comes in at 4.6s from its twin turbo V10 but limited to 250Km/h. Time the Germans broke that 250 Km hand shake, what’s the point when you got a V10 twin turbo waiting to easily explode to 300Km/h.
The Brabus C63
It was only a matter of time before German tuning houses started playing around with Mercs latest C Class offering the C63 AMG. This mean machine deploys a V12 twin Turbo 6.3 litre lump, twisting out 1320Nm. Huh? Add a tow bar & trailer it would be able to tow around some concrete blocks with that torque. 537Kw on tap blitzing to a claimed top speed of 360 Km/h & the 100 dash in under 4s. BRUTAL
Mods: The Gas Flowed Head
A cylinder head is a block of really heavy metal which consists of a number of inlet ports that allow air & fuel into the cylinders of a motor for combustion to take place. Outlet ports allow waste gasses to be passed out of the cylinders after combustion to the exhaust. A standard factory cylinder head has many imperfections in terms of air flow efficiency. Although these imperfections can be considered minor in terms of every day driving an improved efficiency rate of 20 to 30 percent through the valve ports will result in excellent throttle response & power gains. In race terms it will improve the overall dynamics of the motor.
“Flow” means to smooth out, polish & modify. During the flowing process the valve ports are flowed. The valve seats can be modified to 3 angle seats to aid gas flow. A 3 angle seat basically adds 2 more angles to the standard seat – one at the top & one at the bottom of the seat. During the process of flowing a flow bench is used to measure the flow rate & various valve lifts. This measurement is given in CFM (cubic feet/minute). It allows the engineer to measure flow rate improvements. Gas flowing is essentially a very complex modification that can involve specialized CAD machinery & mathematical equations. Other than that it is an expensive mod that requires a bit of elbow grease. It could play up to the tune of 4 to 5K. The head gasket will also need to be replaced – don’t settle for fong kong parts & stick to reputable engineers.

Drag Scene – Safety Matters
Eish is that an oxymoron?
Bra Laauw strikes again. Laauw in fact is a supposedly safe driver who also tips petrol attendants – bo haroh poyroh (roughly translates to good Samaritan). Unfortunately now and again he ends up with hectic fines which leaves his reputation in doubt. Anyways de man managed to supply an article of an oke caught speeding at 277Km/h in a 911 turbo in the UK. A new British record + 10 weeks in da tronk.
Mo Louis sent me an article from the Beeld of a charoh from Brakpan caught speeding on a Suzuki at 276Km/h (GSX R my guess). Da okes punishment handed down by the court is 150hours community service at a morgue in lenz. Shame, that’s hectic. 2 questions
I wonder at what speed da oke will be running home from after graphing at da morgue?
What da hell Louis you readin da Beeld? ya Afrikaans was never your strong point …
Finally enter Sato – de man has been quite. GTR at Heart, he referred me to this article of er oke in a Skyline GTR caught speeding at 261Km/h near Wesbank raceway on the N3 Germiston, apparently the “highest recorded speed violation in the Ekurhuleni metropole” chasing him was a Subaru at 188Km/h and Focus at 184km/h. After the sentence he’ll definitely be a Sut ‘o. Pic below courtesy dead ‘o.
