My project supercar
Discussion
Here is my car...... its not complete (I estimate around 20% thus far) as I am building it from scratch.
The car has been grown from my desire to own a supercar but lacking funds to do so whick I guess its a common problem Lol.
The engine I'm using is a BMW V12 from a 750 and fitting twin turbo's (hence GTT) so it should go well, the engine management is an M800 and I had new Garett turbo's made up to my spec.
The body is my design and I have been modelling it from my mind as I lack the skills to do proper drawing first, therefore I have had to remake almost everything more than once to get the shapes exactly as I want. It's a slow process but I think it's finally comming together, I hope to be making moulds early 2007 and have a final body in the summer.

The chassis is a bespoke item made by me from scratch, as are the wishbones although I did pay a profesional to design the geometry and help me with the basic chassis design.
The uprights are alloy blanks front, steel fabricated rear and are machined for Porsche 996 hubs and upgraded motorsport bearings.
Gearbox is from a Posche GT3 cup race car which I hope will cope with the potentially huge torque the engine will produce.
The Wheels are KAHN 19in split rims with Enzo 345 rubber on the rear.
Its a decepivelly large car as it's in fact 2m wide and just over 4m long, but I have tried to make it look lotus elise sized to keep perspective.
Colour will be a surprise as I'm keep that a secret even from myself.

Thanks for the replies good to know I'm on the right lines as I've never done this kind of thing before and I often find myself bashing my head against the nearest wall in frustration.
I currently have no plans to sell the car as it's a hobbey and I'm not convinced there is a market for it. However never say never.
Been having fun with cardboard and mocking up the rear end over the last week and after many iterations here is the latest with some colour added in PSP.

Hi
The chassis is made entirelly from tube and the roll cage is made from T45 which is twice the strength of std steel and not normally used in this kind of projetc as its a bit overkill.... I bought it for a different purpose but that didn't stop me using it.
These engines respond well to turbocharging as they run 8.8:1 cr as std and just slapping turbos onto the std engine produces between 500 and 600ftlb at the wheels..... I am aiming for higher revs and a few head tweeks but power is guess work at the moment.
I am using twin alloy rads one each side of the car and they are fairly large (500mm square), there will be an upgraded RX7 alloy intercooler each side of the car as well.
I do like the example rear ends people are posting up.... I,m not yet sure the rear is right yet and it definatelly needs refinement.
Cheers
Andy

There is plenty of inspiration in there and the Porsche GT is pretty much my ideal car as a package.... in fact the cars that I take inspiration from are Porsche GT, Keonigsegg, Mclaren F1, Enzo and the Zonda.
I am trying to keep the design unique though which is harder than I originally thought.
Regarding wind tunnel testing, its very unlikelly as its a one off at the moment and I can't justify that... cd will not be a problem and the downforce should be fine... its the airflow through the engine bay that needs to be planned and this is what is driving my design for the rear end. function first, form following.
I have an airodynamasist coming round in a few weeks to provide advice before the rear is finalised.
Without doubt the body is the hardest part of the cars design IMO.

Well I guess the wheels are definatelly a personnel preference (I don't like the ones above, too 80's for me), these kahn ones are designed for Porsche and Ferrari aftermarket fitments.
maybe its the pics I have done.

You also need to bear in mind that these are 19inch wheels and need to be capable of fitting the 345 tyres I have on the rear.
The rear is definatelly not staying exactly as the original PSP pics.... I love Davi's version although I am not sure I could incorporate the lights in that recess, but the grill looks spot on. I will definatelly be mocking up a grill like that as well as the versions I have to see what looks best.
I am a 3D visual man and am mocking up the rear at the moment so that I can physically play with the design.

The problem is the light design itself as they are a recess design and can not stick past the body.....
I am using wood, fibreglass, foam and filler to make the buck, I will be making moulds as the body is mega heavy and fragile.
Regarding the droop, I have taken my best judgement on the curve below the wheel centreline and I will need to check they clear on full droop (2in) before I finalise them.

This was what I was thinking..... I'm not 100% sold but I don't think I am not going to get any closer with an electronic pic so I will finish mocking it up.... I have the shape made and the lights fitted (which are far nicer than my PSP attempts at mocking them up) just need to get the curs in the panel (as I think you suspect its not flat on either plane).

I actually need to split the rear panel to allow for a shut line this was why I had the vent spanning the car previously so that it could be done without it looking strange.
Basically it needs to be slightly above the number plate as this is the height of the chassis behind that I will hinge from....
The other thing I was thinking of was to have a slight gap between the lower defuser and the actual rear pannel to also vent air from the engine bay.

currently this is a one off with no plans to produce it.... never say never, but I can't see there being any money in it and its mearly a hobbey for me as my real job is very different.

I'll hopefully have a new pic to work from soon with the lights in and the bodywork above the lights also done by the end of tommorrow... Thats asuming the wife doesn't drag me in to do yet more work on the house as she did today.

Here is a pic of the car as it is now, I have added the rear spoiler and the rear grill in PSP.
Also I have slapped a very basic fog light pod below the number plate that I will have to work on.
I'm still not 100% sure about the shape of the rear grill yet.

I thought that Canam was your last name. The problem with the fog light on a self build is that it must be at least 200mm away from the brake light.
I still have work to do under the plate as the black splodge is actually supposed to be another small grill and it will be a very different shape to blend much better and add to the look rather than ruin it as my feedle attempt has done...
The biggest problem I am facing at the moment is that the Wife doesn't like the slat and I do.. so the big vent still represents a design challenge.
Why didn't I just build a Lambo replica!
