Luxury Car New
Auto Salon Aussie Car
Theo and George Spartalis are not ordinary, and their cars are certainly far from average, often seamlessly integrating show quality build finish to hardcore race-style performance engineering. Both of these very special brothers shine on like crazy diamonds in the coalface that is the tuning scene and this wild S15 is Theo's opus, his toy, his pride and joy. Rather than keeping it placid with big rims, dumped stance, some styling efforts and around 250kW at the wheels, the Spartalis brothers took their inspiration from the most hardcore drag and circuit racing Silvias in Japan.
Theo made a pilgrimage to Japan a few years back, where the sight of the HKS Kyushu S15 running 10.4 on drag radials and using an SR20 pulled the strings in his mind, while it was witnessing the GT300-class C-West S15 JGTC racers (now Super GT) that stamped those formative lustful ideas and dreams into a cold, hard, wanton desire to build his own SR20DET-powered S15, something that could run a number at the drags or blast an enthralling lap out at a local circuit.
At the start of the original build, Theo wanted the car to blend JGTC and drag styles into a road car and then take it from track to strip to street. However, his desire to run a fast time overcame the short-term circuit aspirations and any shred of road usage for the car, and so it slowly turned more into a strip-focused monster, though Theo reckons it can be re-tuned to smash lap records fairly easily and cheaply.
Before this latest round of modifications to really push it into drag car territory to run a number that Theo would be happy with, it had run a best time of 10.24@138mph on radials and 9.23@148.5mph on slicks, though these passes had been plagued with the kind of teething problems associated with massive feats of engineering like what this car packs. They had suffered all kinds of set-backs, from faulty battery charge warning lights, to shearing billet driveshafts, to a programming glitch on the MoTeC accidentally advancing the timing to nearly 27degrees (which would be enough to kill any normal motor)!
The whole build was excruciatingly difficult as the detail had to be off the clock. It had to be supremely well engineered, but finished to a standard that wouldn't be out of place on a brand new supercar or works-built factory racer. Still, running that first nine second pass made it all worthwhile for Theo, and he's rightfully proud of the advanced workmanship that is packed into the fatter-than-a-sumo two-door, the highlights of which are the seamlessly integrated C West GT widebody, the seam-welded chassis, the R32 Skyline GT-R rear-end, the carbon brakes from the USA and that ludicrously large T51R turbo.
The first thing most people spot in the engine bay is that monster HKS T51R KAI turbo, the snail pumps 30psi worth of boost into the now-2.2-litre SR20, though that's managed by the HKS 50mm external wastegate, TAL blow-off valve and Blitz Dual SBC boost controller. You can't run such a large huffer without the appropriate preparation being done to the bottom end, and on the GT Autosound S15 there's enough hi-po hardware in there to make a Silvia junkie drool with excitement.
In the block lies a Tomei stroker crank that has bumped capacity up to 2.2-litres and can spin far harder than the Nissan effort, while Power Enterprise bearings now handle the rpm, heat and stress from the manic motor, being able to turn to over 11,000rpm! While shopping at Tomei, Theo picked up a quartet of their matching 2.2-litre con rods to suit the motor as well as a set of oversize 87.5mm pistons that were then also Nikasil coated for extra strength and installed with unbelievably exotic titanium piston rings that are both lightweight and strong. There's also a Trust sump and oil cooler to ensure the motor's longevity.
Having experimented with both standard and heavily modified heads, Theo has settled on this expensive, labour-intensive set-up that is reportedly worth around $12,000 and packs exotic, intricate detailing like CNC porting, JUN billet plenum, Tomei valve springs and Manley titanium and aluminium valves. On the front of the motor, there is a Nissan VQ45 V8 throttle body and Tomei cam gears, while ARP head studs have been fitted to stop the top-end lifting off the long motor when that massive T51R gets a'spoolin'.
With the switch to methanol, the Sard 1000cc injectors currently doing duty will be joined by a second set. Theo had been running American-made Rochester units, but found them to be less than reliable on such a monstrously worked motor, something that can spell disaster and tens of thousands of dollars down the drain if it all goes wrong.
Helping keep the detonation at bay is the Trust front-mount air-to-air 150mm-thick drag-spec intercooler. This unit sacrifices ultimate long-distance cooling efficiency for almost no pressure drop at all across the massive core, something that Theo's able to cope with seeing how the car's really only running at full-tilt for a maximum of 10.24 seconds at a time.
All that work adds up to 490 rear-wheel kilowatts without nitrous through the auto gearbox (and well over 500 with a manual), but has seen as high as 600kW at the wheels on the bottle, though this was running a very conservative 18deg of timing. Some of the reasons Theo wants to change the to methanol is because alcohol will burn much cleaner than C16 race fuel, run the motor at a much cooler temperature and allow almost 35 degrees of timing, which should add around 200hp to the car's prodigious total!
Having a Better Performance by Car Engine Modification
When you buy a new car or a pre-owned car, in some points, you do not know how strong and fast the car is. You can always try and ask before you purchase it, but it is usual that certain types of cars have certain level of strength and speed. If you are one of the person that like to express yourself when you are driving, or need to have a car with a stronger machine, it is time for you to get a car engine modification.
Car engine modification is one way to pimp out your car. Once you change replace the engine with different capability, your car will turn to a fast modified car. Besides, by modifying your car engine, you can just improve the car performance to be a better one. It might be the sound that bothers you so much, so once you change it, the sound will not be a problem anymore. Moreover, you may want to change your car engine due to its pollution, because there is lot of cases that cars engine produce so much smog that disturbs the health of environment. The other thing that people really care about is the capability of the engine to use too much fuel. That is certainly not good for your budget.
New Luxury Car - Dacia Shift
If you are the fond of new luxury car or want to drive sports car than I think you should look at the new Dacia Shift. With the seating capability of two persons this car is simply awesome. There is transparent removable roof as well. So if you want to see sky from this new luxury car than you do not have to remove the roof. But if you want to feel the wind than yes you can remove roof from this luxurious car.Sunday, August 1, 2010
Mustang-Saleen-S7-Twin-Turbo-Design-Sport-Car
Designed by Saleen engineers, the S7's engine and drivetrain incorporate the latest in modern racing technology. The new all-aluminum V8 engine casting was engineered and tooled by Saleen to displace seven liters. Redline is 6500 rpm. Space age materials and engineering are used throughout, including stainless steel valves, titanium retainers, beryllium exhaust valve seats, an aluminum throttle body, Saleen designed aluminum CNC-machined cylinder heads and stainless steel exhaust system. An exclusive Saleen-designed Front Engine Accessory Drive (FEAD) system results in an extremely compact engine, allowing for better packaging and overall weight distribution. The V8 incorporates a unique Saleen-designed side-mounted water pump, a belt-driven camshaft drive and a Saleen-engineered dry sump oil delivery system. The engine's mid-chassis placement optimizes weight distribution and center of gravity, making room for an unusually tall engine that allows for a very efficient induction system. Air enters a roof intake, passes through a 90-mm mass air meter and feeds into a carbon fiber plenum. From the plenum the air is routed to the twin ball bearing turbos, is pressurized to 5.5 psi max and then passes through an oval-bore throttle body into an aluminum intake manifold with eight individual runners.
