The Car - Lightning Sprint #24
All the details you'll ever need to know, giving you a bit of info on what makes these winged little machines motor around these oval track speedways.
1200cc 4cyl Kawasaki ZX12 engine , Electronic fuel injection, dry sumped oil system , Kawasaki ignition , Rosson Air box , Uses methanol racing fuel.
Spike Chassis, an American chassis, made from 4130 Chrome Moly tubing. With a minimum of 2" clearance from top of roll cage to top of driver's helmet.
Kirkey containment seat.
Wheels & Tyres:
Front Wheels 13" x 7" with no wheel centres they mount directly to the hubs. Inside Rear Wheel 13" x 8" with tyre bead locks on sides of the rim, so you can run tyre pressures as low as 4psi without the tyre peeling off the rim. Outside Rear 13" x 10" with a bead lock on the outside edge of rim, so you can run tyre pressures of 8-15psi, also has a removable centre cover to prevent the rim filling up with mud when racing. Tyres are Hoosier with various diameters and compounds to alter the car for changing track conditions.
KSE Gen II Power steering box that is fed by an electric power steering pump from a Holden Astra. We top all of this off with a light weight carbon fibre steering wheel and a quick release hub to remove the steering wheel when required.
A Winters 31 Spline Axle is used. It is an alloy tube with splines on both sides of it to enable the wheels to be moved in and out to loosen or tighten the car by adding or removing spacers . the wheels and spacers are then kept in place by one large nut on each side , one is a left hand thread and the other is a right hand thread , this is to stop the nuts coming undone as you are driving forward. You can alter final drive ratios by changing the rear sprocket for either more or less teeth .
The engine and rear end are linked by a " 530 O ring chain " with a chain tensioner to keep the chain tight on the car
The rear uses a single 4 spot caliper bolted to the birdcage with a floating disc attached to the axle. On the front only one caliper is used that works on the inside (left) front wheel. The brake on the inside front wheel can sometimes help you get the car into the corner.
The front uses adjustable coil suspension with the coils mounted on threaded body shocks, and the rear uses torsion bar type suspension. The rear shocks are normally adjustable on compression and rebound and in some cases are adjustable by the driver from within the cockpit.
Lightning Sprints use Alcohol fuel which is housed in a special plastic Tail Tank mounted to the rear of the race car. The fuel is fed to the Electronic fuel injection system by a Mallory electric pump , fuel pressure is maintained by a mallory fuel pressure regulator. We clean the fuel with two stainless steel element filters one before the fuel pump and one after the regulator . there is one main fuel tap for the crash crew in case of emergency.
The centre of the top wing provides down force to provide traction for the rear wheels, the side boards on the top wing provide stability when cornering. The top wing can be moved backwards when racing to apply more down force onto the rear wheels by using a hydraulic valve in the cockpit. The front wing provides a bit of down force for the front wheels but mostly directs air flow from the front of the car up on to the centre of the top wing.
A Lightning Sprint can be quite a wild little race car, all the above combined into a car that has approximately 180hp and a minimum weight of 500kg (car and driver ) flying around a dirt oval track, sideways inches from other cars, you know you're alive when she's hooked up, it doesn't get much better than that.
LET'S GO RACING!
