When someone asks the question, How do we make a car faster, its only natural that all enthusiasts jump to any of the following suggestions;
- CAI + FFE
- P&P
- Wilder Cams
- ECU upgrades / Piggybacks
- Forced Induction Techniques like SC and TC
While all the above will defintely make you faster, the 'cost to fast' ratio
will actually make a lot of us very worried.
There is another way by which you can make your cars go faster and it is not going to drill holes in your pocket like the above mentioned mods.
Ofcourse you can have best of both worlds to get an ultimate machine on hands.
Most of you would have guessed it - its weight reduction. The BHP/Tonne factor is not too less a parameter to be factored out when you think of modding.
A swanky 1.5 tonne of steel giving 100 bhp is going to be a lot slower than a 0.8 tonne car giving 75 bhp.
Now lets see what all you can reduce in your car.
Dont add more weight: First and Fore most your ICE. A car without any ICE is probably not going to go down well with all. So stick to basic ICE. All your Amplifiers, Subs, Wiring kits are adding on to the weight of the car. Add to that some load on your battery too.
Reduce what is not required: ok, To decide what is required and what is not, depends on person to person, their usage and thier ultimate objective.
To Start with you can remove the
Spare wheel (if you atleast have tubeless tyres and dont go on for long rides / highway travel)
Spoiler: Spoliers (if designed and mounted properly) are supposed to aid aerodynamics. But for that to happen you should cross a good amount of speed (say atleast 160 KM/hr). Else it is only going to be a dead weight on your car. Most of Aftermarket spoliers rather are clumsily designed and not serve the purpose.
Seats: This again may not be applicable if you are planning a fast street car. But if the objective is a Track / Rally car then you need to take those out.
Extra Bling: Neons, Fog lamps, Fancy Atennas (some have more than 5-6 in their cars), any dolls, dogs and danglings that are inside your car all will have to get out. Its better we keep the car as stock as possible.
A/C: This will apply for a Track / Rally car. take out the A/C and you can reduce some good weight. The compressor, Condensor and goes with it. (Anyone dare enough to do this in a street car ?
)
Tyre upsize: While upsizing tyres will surely make you take a corner better, going over board with it will make you much slower in the straights. Also, light weight alloys are preffered over Steel rims (But I am not really sure how light weight our alloys avilable in India are)
Carbon Fibre: Ok, Some cash involved here. carbon fibre can replace most parts of your car, but make sure you use it as required. For Example: Replacing the front doors to carbon fibre would help greatly reduce weight, but if your builing a street car, then your saftey is compromised. You ll have to let go of the side impact beams that come with the stock car doors. Ideally a the Bonnet, trunk lids can be made from Carbon fibre. Please note that this will however involve good amount of Vitamin M.
Use of light weight parts: This involves some Vitamin M. The Suspension parts along with engine components make up most of a cars weight. Replacing suspension components with suitable light weight aftermarket setups will help you lose considerable weight. (I am not sure if Aluminim based suspension are out in market, but they will be really heavy on pocket). Lightend flywheel may sound more of an core engine mod. While they help in betterment of Rev response, they also contribute to loss in weight of the stock car. Remove the cat con (if foir Track use) from the exhaust - This apart from marginal improvement in getting out the wastet gases fast, also reduces the overall weight of the car. i am not getting into Engine components here as the objective of this post would be contridicted.
Saftey features: While this may seem stupid to do in a Daily drive / street car
(strictly not recommended), doing this for a throughbread race car will be beneficial. Instead of your Dual Airbags, a proper Roll cage would serve the purpose.
Fuel: This applies again for Track use only. A fully loaded tank will be much slower than a half loaded tank. While its is not feasible in street use, it finds great use in races.
Now imagine doing all this (ok, not all atleast feasible ones) and then getting some engine mods (as menioned above). Wow, must be some fun when ripping those cars out
Request Guru's to add on, i have very little knowledge in this field so please correct me if i am wrong in my statements.
Mods please include if there is already a similar topic.
Thanks
