Car Hacks & Mods for Dummies

Before making the purchase, I joined several online forums for enthusiasts in order to get a good reading on how happy people are with the particular model. I was amazed at the vibrant communities built around websites such as evolutionm.net and nasioc.com. A wealth of information is available, but the data is surrounded by noise. For every knowledgeable enthusiast, there are many more misinformed or incorrect speculators whose opinions usually spring from personal preference or a need to hear themselves talk. Enter David Vespremi's Car Hacks & Mods for Dummies." Read on for the rest of Sizemore's review. Car Hacks & Mods for Dummies author David Vespremi's pages 384 publisher Wiley & Sons rating 9 reviewer Donour Sizemore ISBN 0764571427 summary Presents the big-picture view of car mods that have to do with making the car stop, go, turn, and keep the occupants safe.

In general, I steer myself and others away from the "for Dummies" book series since I believe a lot of material at this level can be found on the internet for free. HOWTOs and tutorials abound for using and modifying most consumer products. In this case, the time saved from filtering online discussion is well worth it. The book is well organized, with separate sections devoted to handling, power, braking, engine management, safety, and cosmetics. There are 26 chapters spread across 360 pages. As you can see, chapters are short and can be tackled easily during lunch or a short taxi ride to retrieve your broken car.

Slashdot readers may be surprised to learn that there is no discussion of entertainment electronics such as stereos or car-mounted computers. This should not be confused with engine management units (ECU). ECUs are discussed at length. Car Hacks & Mods for Dummies main focus is making your car go, stop and turn. Sections were added for safety and cosmetics, but performance is by far the emphasis.

The book does not actually explain how to do any specific modifications whatsoever. Instead it serves as a guidebook to learn what options are out there and compare one upgrade path to another. For example, there is a great explanation of the differences between a turbocharger and a supercharger, but you're not going to get an analysis of the mods required to support your brand new 10.5cm hotside. Instead there are careful treatments of the pros and cons associated with almost any upgrade car car enthusiast may be considering. The coverage of jargon and rating systems used for various products is especially useful. Whenever a new subject or car component is mentioned, the author goes over regulating and standardizing bodies (the DOT, EPA, and SAE) as well as explains how parts, pieces, and fluids are rated. While this is useful when thinking about a new project, it isn't the information someone would want to rely on once they begin such an undertaking itself. The author clearly states, "this book is not intended to be an instruction manual."

The author gets high marks for addressing safety -- both the driver's and the vehicle's -- before any modification. The emphasis on maintaining legal and effective safety devices on a tuner car is something you are not likely to get during an argument about which upgrade path is optimal, nor is it obvious that many safety 'upgrades' -- 4-point harnesses, flashy roll-bars -- actually decrease driver safety when used on the street. In addition the author consistently gives warning when introducing a mod that could put added stress on a vehicle.

If you are a professional mechanic, this book is not for you. You already know most of the contents. Mechanics would be better served by product literature and shop manuals. If you are thinking about modifying your car, but don't have any idea where to start, this is probably a good place. Just be sure to read the first chapter. Car modding quickly becomes expensive, and jumping in without knowing the attached costs (which this book addresses) can be a financial nightmare.

    In my opinion (a WRX), it's best to leave any mods/upgrades to the experts. If you have the money to spend on mods, you should have the money to pay for the experts' time.

      You've obviously never taken any aerodynamics classes. The point of the spoiler isn't for traction, it goes along with the basic understanding that an airfoil will provide a significant horsepower increase. Your typical spoiler on a Civic will increase horsepower 40 to 60 percent.

      Take airplanes for instance. They need a large amount of thrust to get off the ground, so aircraft engineers went ahead and put TWO big airfoils on each side, as well as some smaller ones in back.

      It's all simple engineering really. Let me guess, you think that stickers are purely aesthetic, and don't serve their main purpose of abrateable heat sheilding during fast runs?

      I believe DogDude's point stands.

      DogDude didn't relay a point, other than he's ignorant of why people put spoilers on front wheel cars (As if the answer is different than rear wheel cars).

      One place you won't see "ricer" nonsense is on the drag racing track. But you will see wheelie bars and spoilers on front wheel cars.

      No, a front wheel car is not in danger of doing a wheelie, but the wheelie bars do help keep the front wheels from lifting and losing traction.

      From NHRA magazine (talking about the for-runner for the car pictured in the link)

      Bergenholtz earned his nickname when he and his brother, Ron, reinvented the wheelie bar and then broke the 10-second benchmark in the quarter-mile. Wheelie bars are like car training wheels. They trail behind a dragster, preventing it from tipping over backwards on launch. The Bergenholtz brothers put wheelie bars on their '89 Honda CRX - a front-wheel-drive car, which, by definition, cannot wheelie. On a front-wheel-drive car, the (now slightly misnomered) wheelie bars shift the center of gravity forward. They prevent the rear shocks from compressing at launch. This is, in fact, genius in its simplicity: Gain traction by planting the front end more firmly on the tarmac.


      Moral of the story? When someone complains he doesn't see a reason for something, that is not a point its an admition of ignorance.

      As to your point about caving in the rear deck, they can handle the weight of a 300lb person, at most denting the sheet metal. 300lb of downforce is quite a bit.

      That said, they are probably superflous on many cars. But I'm not going to go parading my ignorance by laughing at it. You never know.
    3. Re:Spoliers! by Osty · · Score: 5, Informative

      You're all somewhat wrong. Spoilers create downforce at _any_ speeds, including 0 (more weight). It's only really appropriate at higher speeds though. An FWD car, while not up high on the list of "needs more downforce" (FWD cars usually understeer very terribly because the front wheels have so much force (and usually weight by design) on them), but any car will benefit from more downforce in the "able to stay on the road while turning" category.

      You're also wrong, by the way. A spoiler doesn't create any downforce. A wing is used to create downforce (negative lift, as the wing is exactly the same areofoil shape as you'd find on an airplane, except inverted). A spoiler simply "spoils" the lift generated by the inherent shape of a car. A car is roughly shaped like an aerofoil (rounded on top, flat on the bottom), and thus at higher speeds it tends to generate lift. It's certainly not enough for your car to actually fly, but it is enough to reduce traction necessary for handling and braking. By spoiling that aerofoil shape, a spoiler lessens the natural lift generated by the body shape of a car. For most non-racing applications, a spoiler is all you need, and in most cases you don't even need that (most factory spoilers are indeed cosmetic -- why is it that a Chevy Cavalier needs a spoiler, while a C6 Corvette doesn't?).


      In a racing application, a simple spoiler is often not enough, however, and it doesn't really matter where your drive wheels are in that application. That's why you'll see touring cars like the Acura RSX or TSX, or the Mazda 6 with big wings in the Speed World Challenge races (and other touring car series). These are fully adjustable wings that generated downforce (the amount determined by the angle of attack, just as the amount of lift generated by an airplane is determined by its angle of attack). You simply do not need a big-ass wing like that outside of a full race car. That is why the ricers are silly for putting big ol' wings on their cars (well, aside from the facts that they suffer from "bigger is better" and "more is better" syndrome with huge and multi-level wings, and that 9 times out of 10 the wings they're buying are not fully adjustable, and that 10th time the wing isn't properly adjusted for the conditions).

It's quite frustrating to check back a while after a request to find two pages of rim polls burying your post past the 1-3 pages most people bother to read. Some people resort to adding a photo to their post to get the camera icon next to their thread so people will open it even if the photo is unrelated to the help request.

    Then there are the large number of people who, frustrated by this and by the search function that seems to be totally incapable of actually finding anything, post a nice query that obviously took some time to set up, only to be greeted by people who post "Use the search" or screenshots of the forum software toolbar with huge arrows pointing to the search function ... which has probably already been tried, with no success.

    So, I recommend the forums, but use the more-specific forums for your problem ... although the sad fact still is that fewer people traffic those forums so you'll have to wait longer than you should for a real answer.

We were discussing the details of the power, handling, etc. modifications that they would be making to my Mitsubishi Evolution (the car they in which they specialize). For the entire time I delt with David (before he left WORKS to pursue other things, like the book) I was consistantly impressed by his comprehensive knoweledge of both the technical and legal aspects of vehical modifications (especially impressive in good ole California thanks to strict emission standards).

    His expertise and professionalism have resulted in him gaining much respect within the Evolution community, and although I have not yet had a chance to review his book, if it's anything like the conversations I've had with him, you'll be amazed by just how far car tuning has come.

    Before talking with him, I didn't think it was safely possible to take a $32000 car, $7k of tuning, and end up just a hair short of a supercar*. Amazing.

    The whole reason for test and tune day at the track.

    That grouping can be catorigized into two types of people. Those that actually race and those that do not. People have many different goals when it comes to building a car: looks, straight line speed, handling, and durability and almost always some mixture of each. With that, you get different opinions on what works and what does not.

    There is some gray area.. Examples.. Some people remove the cooling water supply from the throttle body on cars so equiped. Some think it heats up the incoming air to much and others think it is required to cool the throttle body. Another one. At a 1/4 or 1/8 mile track, many people are pushing their cars to the line and apply ice to the intake, others run it to the line and have the car at normal operating temperature. For some, the colder denser air seems to be an advantage, for others, having the temperatures in the normal range puts the cars computer in a closed loop and running at its peak as it is not compensating for lower temperatures (retarded timing, incease in idle, higher or lower fuel/air ratio etc...) Each of these examples are really effected by what else the person has on the car and some are opinions. The actual indicator of advantage is the clocks time.

    My point..
    The people that actually race the car and can compare before and after times are the only ones that really know the true effect of a modification. 10 degrees advanced timing or 15 degrees? You will only know the true difference between the two on a track with a timer. Optimum tire pressure for your tire and suspension setup? Who the hell really knows without repeated timed laps.
    People that NEVER go to an actual track or an event are not the ones you want to blindly take advice from, those are probably the same people that put a new muffler on the car and swear they can actually feel the difference. I doubt anyone in the world can actually feel the difference between a real world difference of .01 to .1 seconds in a 1/4 mile let alone from one stop sign to the third telephone poll.

    The time clock should be treated the same as running a doom3 timed demo after changing your memory timings. Does it just feel faster or do you have something indicated to back it up? That can seperate FUD from speculation.

As with the computer groups, there are a bunch of newbie folks and those in it just for the image... but for every ten of those there seems to be one or two knowledgeable folks.

I'm still in the fix it stage -- trying to put a car back to complete stock condition. It's almost like restoring an old Atari ST or Amiga to full functionality. E.g., the other day it took me a couple hours to change the front fog lights. The bolts had frozen up and grime had covered one of the screw holes so it wasn't immediately obvious how to remove them. After lots of cleaning I got them off, changed the bulbs, and got the housings repainted. The second time around it was a fifteen minute job.

    If we work under the assumption that the wing in question actually produces signifigant downforce (not a trivial assumption, given the typical aluminum extrusion pretending to be a wing from most rice shops) the download generated by the wing will be borne by all 4 tires.

    Depending on a number of parameters, the rears may carry a larger share of that download, but the net effect will be increased normal force on the front tires, which in turn increases grip.

    Now if our boy was smart enough to use a real airfoil on his wing, he was probably smart enough to fit a front airdam and splitter, which means he probably has way more FRONT downforce than rear, and is probably using the wing to help balance out a high-speed oversteer condition. On production-based cars, building front downforce is much easier than building rear downforce.
