I send you an e-mail. Either youre an awesome BS-er or you really know what you're talking about. So far his suggestiosn look liek hte best...so critiqueing his suggestions, an giving some comarisoons, and adding some more specifics, ideas, brand-names and models, or anything would help(from the rest of you). Anyways, I hope to discuss thsi stuff in detail with you through e-mail.

Aeroynamically, I'd suggest the "gound effect" design of the bottom of the car, and a well-designed diffuser. You might even not need any wings (look at the Enzo), as wings produce drag, while the downforce at from the underside of the car is "free". And leave the wing mirrors off as they also produce drag (unless you need them for a particular airflow over the bodywork that you need) - use small cameras instead with a lens that allows a wide angle of view on the sides and on the rear.

^^ My mistake! I forgot that brake discs don't gas anyway. :o They DO need to be cross-drilled or slotted if used with gassing brake pads. Quote:

All right, some quick stuff about dimensioning.
As low as possible, definitely. Wheelbase need not be as long as you can make it, as the polar moment of inertia would likely increase. A high width/length ratio MIGHT be good, I have to look further into that.

Chassis
// Aluminum honeycomb-reinforced carbon fiber laminate monocoque Longitudinal mid-car engine mount \\ Body // Carbon fiber laminate body panels *Removable carbon fiber rear wheel well covers, optional. I don't know if using them will affect brake cooling or possible brake duct airflow.* Impact-modified polycarbonate windshield/windows *you may want to make the windows fixed (unrollable, etc.) to save weight* \\ Aerodynamics // Carbon fiber front air dam /w electrically-actuated bottom lip *increase angle of attack for more front downforce, decrease for less drag/higher speed* Carbon fiber rear spoiler /w end plates *the shape and number of foils, etc. depends on shape of car, I should think* Carbon fiber underbody panels /w built-in diffusing sections *again, complexity of diffusion panel depends on shape of car?* \\ Steering // Carbon fiber steering column /w pair of aluminum U-joints Titanium carbonitrided (hereafter referred to as TiCN) aluminum rack/pinion *gearing of pinion/rack teeth up to you* Carbon fiber tie rods \\ Suspension // Four-wheel double wishbone suspension Forged titanium OR steel Heim joints Carbon fiber wishbones, unequal-length non-parallel control arms Shotpeened cold-wound steel springs Fully-adjustable billet aluminum oil/N2 monotube dampers \\ Induction // Forced induction still under consideration? Some kind of air filter... foam or oiled cotton, placed in area of direct airflow Ceramic-lined/coated hydroformed aluminum intake tubing Aluminum tube/fin intercooler(s) if using forced induction Hotwire air sensor Hydroformed aluminum OR magnesium intake manifold Welded hydroformed intake runners, possibly telescoping \\ Fuel // K&N stainless steel fuel filter will do fine Electric in-line fuel pump(s)? Billet aluminum fuel rail(s), fuel pressure regulator(s) *not much here, I know* \\ I'll get around to the rest afterwards...

For current dimension plans, go to that "top secret" page.
http://phantom.ssip.net/Files/Predator%20Chassis.htm I'll be updating that semi-often. ========Width================== I'll probably try to decrease the width of the car by 2-6 inches from the planned. I'm not sure if that wil affect the interior or anythign else yet. I'm studying my asthetic & physical desing to see what it can handle. Is 80 too wide? Currently: http://phantom.ssip.net/Files/Predator%20Chassis.htm ============================== ========Brakes================== Which brake setup should I use? What would be the pros and cons of each. Would ceramic use cross drilling/groves? Currently: http://phantom.ssip.net/Files/Chassi...&%20Brakes.htm =============================== ========Engine================= Look at.... http://phantom.ssip.net/Files/Chassi...ne%20Stats.htm ...and critique the various options. Make additional options or add mroe information to the current options if you would like. =============================== ========Seats============= I'm looking for dimension or a diagram of the Sparco Milano, plus it's weight. If anyoen knows the company homepage, or could find it, I could probably e-mail them for that information. ========================== critique anythign else..jsut bringing some issues up.... Hmmm...jsut got another reply...reviewing....well, I'll update my statistics accordign to your suggestiosn in the previous reply, but it'll be a little while before they are on the site.

The most recent versions are soooo much more attractive than the first images you posted on the version 1 thread. The orignal design's sides were too flat, making the car look too cheap. I realize that flat sides create more interior room... but ugliness creates less sales. IMHO the new, big side intakes look good! Think Lotus Elise when it comes to Complex Curves (harder to model, but great for sales).
If you'd like any help, I know a thing or two... went to ArtCenter for a while. E-mail or PM me:smoker2:

Be careful how much you take out of the cars width, not only does that often force things to be mounted higher in the chassis (meaning a higher center of gravity) it increases weight transfer to the outside wheels, pulling traction from the inside ones on a turn. Obviously you need some transfer to the outside so super wide isn't good, but it needs to have a balance.
Double wishbones are nice, but they eat up room like candy, It's definitly the way to go but make sure you keep that in mind, a large reason why the corvette has a large rear is because of the room a good double wishbone setup takes. Plus whether the design needs to use equal length or unequal arms in order to keep the wheel vertical. Have you chosen what engine you want to use? I don't suppose you'll be making your own design for this specific car, so theres a host of engines you can use to help you choose the size of a car you'll need, those DOHC V12s are monsters. |

So 80 inches isnt too wide. I dont actually want to reduce the width.

Engine: what was said about the injection is that direct fuel injection is not really needed. But "normal" fuel injection is still a must - don't want to be having carbs in there, do you?
In my opinion you should be looking at 1500 - 2000 hp out of the box. That would make the car the ultimate supercar. I know this sounds like much, but there's no point in having any less. 2000 sounds good . And as you have TC and ESP, it should be reasonably easy to control. And a couple of things about these aids. Make it so that it would be possible to disengage all of them at will (for a bit of fun), and also make TC adjustable by the driver from no wheelspin to slight to completely off.

Also adjustable from the cockpit brake balance and I like the idea of being able to adjust the stiffness of the shock absorbers fron the cockpit as well (fronts and rears separately).
I'm against a rear spoiler as it will add drag and if it's made retractible - it will weigh too much (?). Adjustable frot airdam -
