supercar idea

[Anaema]

i have a shitload of specs on a supercar i would like to build(someday in my lifetime) at another forum. i tried to post a direct link, but Firefox still wont let me, to my amazement. so, just go to forzaracin.tz4.com and look for the thread named "revised supercar", it should be shown on the opening page. if not, its in general discussion near the top.

ive been rethinking alot of the specs on this... you could call it a dream car if you want . i also rethought the valve system i thought up a few months ago, and revised it for pull type valves instead of poppet type valves. ill post more on that too.


notes: the car is meant to run on alcohol fuels only. due to the high compression ratio, and for HP reasons

what V12 are you planning to use?
do you have plans?
do you have about a cool $mil to play with?

there's some pretty exotic sh1t in there....

 

[Anaema]

lol. yup, thats the one. nearly every piece of that car would be carbon fiber, the body, the frame, all of it. excepth the engine of course. my imagination has no bounds when it comes to cars. it would be a demon if i could build it... but im only 15, and well, i dont have a million. but even then, it would take far more than 1 mill to design and develope this car. and who said i would use an existing V12? (hint hint). there would be no steel in that car AT ALL!! none. its either aluminum, magnesium, titanium, or carbon fiber. it would be loud, and it would be fast. so fast it would scare people. imagine a racing version with no mufflers and no emisions equipment

. oh ya, and exotic. like the 15.5 inch carbon-composite brakes? the hydrolic valve system? the carbon fiber A-arms? the absence of steel and iron alloys? the pushrod suspension? oh wait a minute! steel pistons, almost forgot.


damnit, there are still some typos in there. its like i cant excape them!!

 

[Pro]

considering your age and the budget constraints that would come with that - i would steer into something a little more "off the shelf".

try using chromoly tube for the space frame, replacement vented discs and calipers from a factory motor vehicle, try using an Miata rear clip for the IRS diff and alum mounts / brakes.

power it with a 1UZFE to keep it cheap and powerful and teched up.

you should build a mould of the body you wish to use, 1:1 scale out of wood, bog (filler) and fibreglass and when you have a shape you're happy with then make the panels out fibreglass by laying strips over the car to form panels. do you have any idea how EXPENSIVE carbon fibre is?

steel out the fibreglass (using 1in square tube) to reinforce the panels and you're about a thirdof the way there.

i suggest you check out some hot-rodding websites like www.ozrodders.com for example and check out the construction sections.

i mean, it's okay to dream but i have no time for dreaming. i'd rather put my energy into MAKING something i can drive rather than dreaming about what i'd build if i won the lottery.

but hey - it's your fantasy right?!?!

 

[Anaema]

its just a dream.... would be a damn sweet car though. and besides, im 15. i wouldnt even have the money to build what your talking about.

 

[Peewee]

Bore x Stroke: 88mm x 82.2mm

FYI, that equates to 5604cc or 341.6ci.

6000cc (365.7ci) on that Bore would be 85.0545mm stroke
On the 82.2mm Stroke the Bore would be 94.219mm to give 6000cc

 

[Pro]

why keep it a dream though?

why not make it a reality?

you may have hidden talents that could put you up there with Enzo Ferarri and Bertonni etc etc. you may find after you make it you get asked to make another and another and another!

check out www.carbontech.com.au

do you have a shed? if so, get to work!!!

 

[Anaema]

whoa, maybe when im older. being 15 is a serious restiction.

 

[Pro]

well, that kind of attitude will get you nowhere quick...

 

[jibby]

15 Anaema, why your just a kid, cool....that is not a restriction that is a great age to start.... I wish I was 15 again, I am now 37 and getting a little grey hair....but I still got that youthful spirit and the body is still holding up, thank god....

Dream on nothing wrong with that!!!!!!!

 

[urtwhistle]

if no 1 dreamed any thing up when they were young, we would still be living in caves

 

[Anaema]

well, that kind of attitude will get you nowhere quick...

so planning to build something cool when im older, even though im only 15, is an attitude that will get me nowhere fast? that makes no sense.

 

[cjsupra90]

no what they are saying is to start now, dont wait. if you have the attitude that you are to young to start then its not going to get you anywhere. You are never to young to start.

I started learning and working on cars when I was 6years old. I assembled my first motor when I was only 8, well did everything that I was physically strong enough to do. obviously I couldn't lift the heads on to the motor of torque all of the bolts to spec, but I did what I could.

Point is, you are almost never to young to start.

Do it, research all that you can and learn and start.

 

[jibby]

I rebuilt my first small block Chevy at 16, then quit cars completely at the age of 25, got to busy running business and trying to make money...and had no extra time. Now I just got back into these cars about a year and a half ago. I am truley amazed at the technology advancement since. I still get a little lost at times....but learning fast and have a pashion for it once again like I did when I was 16, that is the key....and I am having a blast.

oh, well if thats what you means, then im planning on buying a old VW beetle and turning it into a baja bug. or possibly a 240Z and modifying one of those. ive got an old truck im selling for 1500$, and that should get me started.

 

[Anaema]

a friend of mine has an idea for a low cost, turbo sports car at the same website. check that out too. it would be much easier and cheaper to build.

 

[340i]

nice
id add some kevlar to the tub for a bit of toughness. and maybe two turbos. that would be cool. if you're gonna dream, it may as well have four figure power (in kw, at the wheels!). with some hard work you could be driving this in a decade (or two).

 

[Anaema]

i do have an older design with twin vaned turbos and a V10. putting out around 900 HP.
