Welcome to my latest project, the Spartan V8 prototype roadster.

Take a look around, and feel free to leave a comment!

What is it?
The Spartan V8 is a type of high performance car called an "exoskeleton" car, exoskeleton referring to the framework of the car which is both visible and aesthetic by design. It is being designed entirely from scratch, by me alone (constructed and tested entirely in SolidWorks). I'm about a year into the design; from initial idea, to working concept, to full 3d virtual model. Once I have the remainder of the crucial components (engine, transmission, suspension, etc) modeled accurately in 3D, I'll be able to finalize the design and begin construction.

What would it be like to drive?
Something like this.
The metallic click of a switch engages the ignition and fuel pump with a hum. You engage the clutch and push the starter button.. the V8 engine thrashes and bursts to life with a snarl, sending shivers through the frame, and straight up your spine. The shifter in your right hand snicks into gear, and you ease out the clutch and apply the throttle.. by the time you fully release the clutch, its already time to shift into second. As you shift to 3rd, 4th, 5th, and 6th, the sheer acceleration nails you to your seat, the exhaust roars to either side of you, the intake growls in front of you, the big 305 series tires shriek in protest as they claw at the pavement, the wind whips past your head and body, and you are catapulted to speed more rapidly than you thought possible.
A stab at the brakes invites the race compound pads to bite into four oversized vented rotors, rapidly bringing you to a screeching halt.. brutally throwing you forward against the belts of your 5 point harness, threatening to eject you from the cockpit as you slow back to a stop. Your pulse is racing, your breathing is quickened, and the back of your neck is tingling. Savage and raw, the Spartan V8 isn't just quick. It is downright terrifying.

More akin to riding something wild, overpowered, and foaming at the mouth than just driving a car. It roars, it screams, it snarls. It thrums with power lurking just under its thin skin, daring you to mash that accelerator to the floor, and chase down something exotic..

Why design and build your own car?
Why not? It will be fun to design, build, and drive. It will be a learning experience like no other. Also, because of it's tremendous power to weight ratio, the Spartan will be a veritable supercar - more than able to hold its own on the road or racetrack against other street cars costing hundreds of thousands of dollars.

Check back whenever you like, as I'll be adding updates frequently.

T56 Transmission

I recently picked up the six speed transmission for the Spartan, which means I can now get a much more accurate model of the transmission into the 3d assembly model of the car.  Once that model is finished, I can mate it to the engine model in the main assembly.  This will allow me to refine the dimensions of the tubes that make up the transmission tunnel in the frame - too much room in the tunnel, and I lose valuable interior space; too little room in the tunnel, and of course the transmission doesn't fit.

I'm still in the process of getting it cleaned up, but will get some pictures up soon.  It also needs to go to the transmission shop for a quick going over to make sure its ready to go.

Coil Brackets

The factory truck spark plug coil mounting brackets and the LS1 intake interfere with each other - the fuel inlet wants to be in the same place that a coil does, so I've made some brackets that slide the coils down and away from the intake.  These use the same factory mounting points as well.  I will be having them cut out of T6 aluminum and test fitted sometime this week.

Test fitted the new bracket on the valve cover, and everything fits perfect - except one hole being a bit off.  Also trial fitted the coils to the bracket and everything fit and cleared perfectly.  I fixed the hole that was off and also added holes for the coil wiring clips, now I'm ready to have two new brackets jetted and installed...  These brackets are also much sturdier and weigh marginally less than the factory brackets.

Two new brackets are made and test fitted successfully, next will be transferring the coils over and fastening them to the brackets, then mounting them back on the motor.

Drivers side coils were mounted to the coil bracket, and installed on the motor.  Looks great, is lightweight, and allows the fuel line to clear the coils with no modifications.  Couldn't be more pleased with the design.  I've had some requests already from folks wanting these coil brackets - you can email me at sbcrx007@yahoo.com or leave a message here if you're interested.
