McLaren Killer thoughts

[zen]

top speed? given the KG aero challenges, i would have to go with NO unless they are changed so radically that it no longer even resembles a KG.

Not a chance, the McLaren is a purpose built car, built by a race car builder, it sacrifices nothing, so the parameters you've mentioned are only a few of the ones to consider when you think about making a "similar" car.

i think it is odd that eveyone says the ghia has large areodynamic issues but nobody can back that up with facts such a down force, up lift, vortex areas, or even a coeffeicient of drag!? drag bugs hae gotten above 150mph and not flipped over and into the beyond, yet the much more areodynamic ghia supposedly cant handle 110+mph?

there are some 10-11 second drag ghias that do hit 140+ and while they arent stock looking (they have a rear wing, whoopdy doo)they arent flipping over either.
you may be saying well hey they are just going that fast for a second or two, true but that is all the time is needed to crash a car at those speeds. those cars were also modified to go that fast and be able to handle it and the body does still look like a vw. so why cant you make a ghia capable of 150+mph for a sustained speed, its all in the suspension and removing the uplift these cars get. surely in all of the Fatherland there has been some guy that has succesfully made a 240+KPH Autobahn crusier.

all im getting at is that is hate when people say ghias cant be made areodynamically stable to do high speeds, that is BS

The Bader Ghia reached 168MPH (270kph) before the journalist I read about got scared.

Here is a link to someone who races Ghias and has a little more input as to the aerodynamics of the Beetle and also Ghia.

Barret Camper has a lot of racing experience and knows from that experience and trial and error.

I tend to agree with Volksdent that everything is a compromise, but with enough money and more importantly cojones, it can be made fast and quick, but I doubt that it would ever make it to 200mph or above !!!

Take care and Happy New Years,

Correction: 186mph (~300kph)

I don't suppose you would just trust me if I said, as an engineer, that everything is a compromise.

To wit, the aerodynamics of the McLaren were a comprimise with the cooling of the car. The McLaren overheats quite readily in hot weather (Road and Track overheated one twice in a day when it borrowed one).

Just buy an ARIEL ATOM with the supercharged Honda and retire with the money you will save . Ghia 0-62 yes 1g skidpad -yes closing in on 200mph club -not very likely but real performance only happens from 0-100-0.

True enough, everything IS a compromise, but that's a basic fact of life. I'm just saying in regards to performance on a paved surface, the McLaren didn't have many. The 1940's Volkswagen design has PLENTY, that being my point.

I've seen bugs flip over from apparently nothing during a drag race, they are not stable. Anyone see the PINKS episode? I've seen it a few times in person at Sacramento Raceway, just the littlest gust and those things go for a ride. Straight line speed in a controlled invironment is one thing, real world high speed driving is another. A Ghia is probably a better option for high speed, but like the quote above, to do it properly would take essentially a complete redesign.
