Supercharger Performance and Engine Performance Parts

Posts Tagged ‘Supercar’

Audi was commissioned to set up a racing car for Hitler for a 1939 race season.

Their weap of choice includes:

Auto Union D-Type V12 supercharged race car...

• A signle overhead cam (SOHC) V12 engine with 2 valves per cylinder.
• Twin roots style positive displacement superchargers in a non-intercooled setup, with a very peculiar twincharged setup it seems where one charger is feeding the other.
• Two Solex racing carburators in draw through setup (also peculiar) meaning that the superchargers are always wet with fuel which can’t be good for longevity of the rotors (but considering this is a race car that doesn’t really matter that much).
• High flow stainless steel mesh air filter screens on the carb inlets.
• A side scoop ducted to feed ram air to the carburators.
• Equal length individual exhaust runners exiting the top of the engine compartment dragster style.
• Magneto ingition system.

The result of this combination is 485hp and a top speed of 200mph. The car was also capable of doing a full burnout all the way up to 100mph.

Supercharger Performance by PPI Design

The remarkable Audi R8 supercar (which shares only 15% of it’s DNA with the Lamborghinni Gallardo), seems to be envyous of it’s italian cousins and looking to step away from Audi’s civil nature and adopt a more sinister attitude.

This remarkable car, with its rear biased AWD and a V8 engine, has been fully overhauled by german design company PPI Design. PPI has released their new 2009 lineup of the R8 at the Monaco Top Marque event. The new car labeled the PPI Razor GT-R is a stage IV modification pacakge on the standard R8 including:

• Interior modifications
• A new wind tunnel tested carbon-fiber aerodynamics package for reduced lift, reduced vehicle weight, and increased high speed stability
• A new Wide-Body look, incorporating 11.5″ wide rear rims with a 325 massive section tires for grip, handling, and stability.
• Fully upgraded braking system with new discs and calipers at all 4 corners
• Improved handling with a special purpose coilover system with hydraulic lift capabiliy, capable of increasing the vehicle ride height by 45mm for in city considerations.
• And last but not least an engine modification package including:
  • A ram-air intake system
  • A supercharger (of which type and manufacturer we don’t know)
  • And a high performance PPI exhaust 

The result of these modifications comes out to 580 hp @ 7400 RPMs with a great acheivement of a 250 kg weight reduction on what was already a purpose built supercar. This increased power to weight ratio gives us a new topspeed of 207mph (332kph) and a 0-60 time of 3.7 seconds for the stage IV package.

Now considering that the 2009 Lamborghini Murcielago LP650-4 Roadster does 0-60 in 3.4 seconds and tops out at 205mph, I don’t think the PPI Razor GT-R now has to worry about being outclassed in comparison with its older cousins – or any of their rivals for that matter.

Carbontech Redback Spyder – Engine Performance Parts

The redback spyder uses supercharged performance for flat torque delivery from 1500 to 6500 rpms

Anyone who’s seen the movie MAD MAX is familiar with Mel Gibson’s ford XB Falcon, with the modified Concord front end and the infamous Blower protruding through the hood. In the movie, Max goes on a vengeful rampage where he is the judge, the jury and the executioner…. I don’t think the movie leaves any doubts as to how passionate Australians are about their cars and it comes as no surprise that an Australian entrepreneur would spend four years of his full time designing, prototyping, retrofitting, and building Australia’s first supercar – suitably labeled the Redback Spyder.

The redback Spyder is based on a solid foundation of a chevrolet LS1 V8 mated to a Getrag 6 speed transmission. The car’s performance is further enhanced by a handful of carefully selected engine performance parts:

·         Le Mans Style ground effects front end to increase linear flow and direct air towards the intake system.

·         A carbon fiber intake system ducted to the car’s roof scoop to reach the cool high pressure air stream passing over the car at speed.

·         An eaton M90 twin-scroll supercharger

·         Custom 4-1 headers and true dual exhaust system starting with 2” primary tubes, into a 4-1 merge collector

·         High flow cat converters

·         High flow performance mufflers

 The result of this combination is 460+ hp @ 6500 RPMS with a very wide power band having at least 405 ft.lbs of torque available from 1500 RPMs all the way up to 6500 RPMs. The car is capable of accelerating from 0-60mph in 4.0 seconds flat and is proven to a top speed of 200mph which is amazing considering how basic an LS1 build this is.
