Firehawks

The stunning DJ Firehawk was designed with two goals in mind, to be the fastest bike engine powered hill climb / sprint car in its class and also the best looking. This has been achieved with meticulous attention to detail and the refusal to compromise on design; the result is a car that not only looks spectacular, but is also able to deliver uncompromising performance when out on track.

Typical Technical Spec (actual spec may vary dependant on customer choice):

Chassis (2 options):

The sleek design and small frontal area means the car is able to cut through the air with minimal resistance. However using the latest CAD design tools has meant that we haven’t had to compromise on strength, torsional rigidity or safety. In fact several of our cars have been in 80 mph + crashes and in all cases the drivers have walked away with only their pride damaged and the cars easily repairable.

Pre-preg carbon fibre monocoque chassis with aluminium honeycomb core, manufactured in house following F1 techniques and methods and built to 2000 F3 technical specifications (weight 35kg).
Steel spaceframe (T45) chassis constructed from precision laser cut and cnc bent tubing which is then TIG welded together (weight 42kg).
Front nose cone is carbon pre-preg with a nomex core, designed to offer front impact protection and energy absorption in the event of a crash.
Rear engine support structure is cnc machined from billet aluminium to give a formidably stiff yet light weight assembly.
Billet sump, mimics standard Suzuki Hayabusa item and means a costly and heavy dry sump system is not required.
Driver controls (pedal box & steering column) are fully adjustable to ensure the perfect fit for any driver.

Bodywork:

Styled by Matt Marcantonio a motorsport graduate from Oxford Brooks with technical advice from a leading F1 aerodynamist, the sidepods and engine covers (high & low styles available) reflect the sleek looks of the Firehawk chassis, whilst the undertrays employ ground effect principles which come into play from speeds as low as 35-40mph, this ensures that the car is really stuck to the ground and has excellent high speed stability.

Side pods are constructed using carbon fibre pre-preg with a Nomex honeycomb core and are extremely strong and offer side impact protection, whilst remaining exceptionally lightweight.
Ducting within the sidepods ensures all air flow is directed through the radiators and intercoolers to further improve performance.
Upper surface of the undertrays acts as a secure platform for mounting items such as oil coolers, radiators and intercoolers.

Wings:

SM Designs profiles manufactured in house by DJ; comprising of a dual element SM153 profile front wing with SM101 flaps mounted either side of the nose cone (this mounting arrangement ensures that the undertrays and sidepod intakes aren’t starved of air). At the rear a dual element SM203 profile rear wing with SM101 flap is fitted.

An ultra high down force option is also available front and rear; this comprises of a quad flap front assembly and a quad element rear wing with twin SM183 main elements and twin SM101 flaps.

Suspension:

All round independent suspension designed using the lasted 3D CAD software to give competitive, safe and predictable handling in all conditions, with the following features:

Anti-squat and anti-drive geometry.
2 way adjustable Ohlins dampers.
Aero section tubing with unequal length non-parallel wishbones.
Easily replaceable rose jointed brackets.
Adjustable camber & toe.
DJ designed lightweight uprights (choice of 2 & 4 pot caliper mounts).
Front and rear anti roll bars.
3rd spring system.

Drivetrain & Braking system:

DJ designed fully enclosed gear drive eliminates the need for unreliable chains traditionally associated with bike-engined cars. Proven to be capable of transmitting power in excess of 360 bhp and 175lb/ft of torque.

Quaife ATB differential.
Easily changeable (30minutes) ratios – 3 sets available.
Pneumatic paddle operated gear shift system.
Ultra light weight 2 pot brembo calipers or high performance Wilwood 4 pot calipers.
In cockpit adjustable brake bias, with the option of digital displays and monitoring.

Engine and exhaust:

Although we are pre-pared to accommodate any engine the above spec relates to the installation of the Suzuki Hayabusa engine in either naturally aspirated form (typical power 170-250 bhp) or when supercharged (typical power 300-360 bhp).

Exclusive Hayabusa exhaust system designed with Renault F1 exhaust software to ensure optimum header / primary lengths and manufactured by SS Tube Technology.

Price:

From £26,000 + VAT for a rolling chassis with no bodywork, inc one set of wheels and single solid colour paintwork (suitable engine & ecu to be free issued)

Above spec would be approximately £35,000 + VAT for a rolling chassis (suitable engine & ecu to be free issued).
