How much time do you shave off by changing to carbon fiber?

[Vette73]

Also be warned a lot of aftermarket carbon fiber weighs more then the orignal part.

Even the suspension arms and uprights are composite. That thing is going to weigh just about the same as a driver+engine+gearbox.

With my truck, if I replaced the hood, fenders, and bed with carbon fiber pieces... I'd probably go from 15.50@90 to 15.20@91. I'd just have a slightly lighter brick. Someone with a less brick like car and heavier sheet metal would gain more. Heck, if I was really worried about weight I'd get some cheapo trailer tail lights and just leave the bed at home and race bareback.

Why would you race a truck in the first place? Trying to impress your boyfriend by drag racing an old lady in a Toyota Corolla?

It's fun and I own it.

Man talk about loaded...

gearing, weight, aerodynamics, and hp/tqe matter more than what your car is made of

If you ligthten your car enough it will really improve your 1/4 mile time.

Hah, that was a really good read.

Lol. The following quotes are golden:

And then there's that entire car just hanging out there behind the rear wheels. Nothing actually happens back there, there's no engine, no suspension mounting points, nothing of any performance value. We can't find any reason why the car shouldn't just stop existing after the rear wheels. If you ever want to make something stop existing, the Milwaukee Sawzall is the tool. Oh, the satisfaction.

...but now we've created another problem. Because of how his car was originally equipped, his goals were obvious, and now, looking like a theft recovery, women will not be impressed. A solution that causes another problem is no solution at all, so we convened for a brainstorming session. From this swirling cloud of brain, Dan Barnes emerges, Sawzall in hand, and utters three simple words. "Chicks dig convertibles."

Not your average grocery getter.

EDIT: A friend of mine and I once took a 1974 Econoline Van frame + engine out for a spin, sitting on milk crates. That thing was hella fast from a roll, but hard to hook up

well look at that... someone already said this

actual food for thought...Audi will completely rethink the way it engineers its cars over the next few years, according to Michael Dick, the car maker?s director of technical development.

Dick says Audi?s priorities are ?hybrid and electric powertrains and lightweight construction for the next-generation version of Audi?s MLP?, its modular longitudinal platform.

Significant weight reduction is very important for the future, he says, because it will be the ?basis for the electrification of the car?.

However, this dramatic weight-saving programme will also be of huge benefit to its conventionally powered cars.

It will help to give them much-improved handling and better performance even with significantly less power.

The MLP is apparently being used as the basis for the company?s ?in-depth? investigation into making future cars much lighter.

The first prototype to be generated by the programme is a special S5 coupé, which is 400kg lighter than the current production version, according to Dick.

Dick says reducing the weight of the bare bodyshell is ?the most important thing? and that ?losing 150kg will deliver better dynamics?.

Although Audi?s lightweight experimental S5 has a 230bhp four-pot engine (100bhp less than the production V8 engine), it can still lap the Nürburgring eight seconds quicker than its V8 sibling, says Dick.

The S5?s prototype bodyshell is described as a ?spaceframe body in white?, which allows Audi engineers to build a ?hybrid steel-aluminium body?.

The engineers can mix varying amounts of aluminium into the structure, allowing a balance to be established between weight saving and extra cost.

Fuel saving has become a much more important part of Audi?s development process, says Dick, with engineering developments now assessed internally by ?euros [cost] per gram of CO2 reduction?.

Not great in an accident either I suspect. :laugh:

i'd love to know what materials they used to drop 400kg. that's incredible.

A lot of it is the motor I'm sure.

You should just lay up dollar bills in an epoxy resin. I hear they are almost as strong and about the same cost. The bling factor is much higher though.
