Yea i've heard of the supercharger for the FD2 (unfortunately) although i remember something about them saying its like a weaker version from the RR.

sorry i dnt have a link but i still think $3K is good 4 a turbo kit
nice ride turbice...come to the next meet man
damn if not for this recession, that procivic turbo kit could be affordable haha >.<
hey guys...put some 20" K-Speed Biaggi's on my FD2 today. Lowered 3 inch in the front and 3 1/2 in the rear. Sits nice and low and no scrubbing at all! Even have full lock in steering!! Washing the car tomorrow and ill have pics up
Thanks mateQuote:

hey i just bought a fd hey...
wondering what the best widths and offsets for 19"s are..
like i know i want 19's yeah.. but.. the offset is the thing im wondering about..
whats the lowset offset i can have on the back without having to pump or flare my guards, and also the lowest possible offset on the front without having to flare my guard and scrub to much....
thanks for ya help :)
Here are a few linksQuote:

those are for Civic Si... are they using the same engine as FD? (i kno this has been discussed be4 but cant remember the answer :p)
i was wrong LOL
hum hum hum... so the turbocharger is a no no?
it goes straight on, or so i was told, i know cause i enquired about it. Apparantly its a direct bolt on.
are you sure they arent confusing the aussie delivered fd2 with the american delivered acura csx which actually has the same engine as the american civic si?
i'm only going based on what i was told when i enquired about it for my car...and are you sure that the CSX does not have the same specs as the aussie fd2...i know that the CAI for the CSX is the right fit for the aussie fd2 and if they didn't have the same engine this wouldn't be the case...right???
ah sorry should have made myself clearer, was saying the csx comes out in a type s version which shares the same k20z3 engine as the si, and the our civic sports uses the z2
but yah i dunno they are both for the civic si lol. best bet is to wait till someone in aus does it first and if it works follow his lead haha

The idea of this kind of modification is to create an undertray...which is supposed to produce downforce.
The only problem is that the car won't be low enough or going fast enough to create any meaningful amount.
this the same kit under the hybrid?
Nothing to do, let me share some info.

1. the covers made the bottom more smooth hence reducing some moving air trap at the under carriageQuote:

3. Fuel consp. improve
and the main purpose is to smoothen the airflow underneath, to reduce drag
this is a simple yet useful mod if you understand the physics about air drag.. but it is also a mod which you can't really feel anything but its benefit does exist in daily driving...
Never be scare with weight, otherwise we never do mods. it's only 2-3 kg, same like we buy 1 whole watermelon from wollies and put in the car;)Quote:

and also if the car going fast (in stock height), may induce air lift (only at high speeds - 200kmh)
That's why, under cc get most effective for car stock height and at max speeds around 180 kmh or at city drive
but simple physics teaches that u cant reduce one factor and not increase another, the ducktail spoiler on the hybrid model probably as a counter to improve downforce when high speeds to counter the effects of the undertray carraige
The undercarriage covers are used to coverup holes/spaces that create air turbulence as a result a more restrictive path for airflow. Ground effect typically come in only at hi-speeds (not very high speeds) say above 80-180kph
extract from google:
The use of extensive undercarriage aero parts was the basis of the Ferrari Enzo bcos Ferrari President did not want ugly spoiler wings on the car surface instead he wanted a fluid body design. The Ferrari Enzo ‘s undercarriage aero parts help generate a down force of 400lbs at speed of 186kph. if u guys go to wikipedia/how stuff works, can find some writeup basically it’s a combination of flat panels & air tunnel. The Enzo only has a boot lip spoiler thats all. Same design concept has gone to the 430 Scuderia.
Do a google search on the Honda NSX JGTC GT500 car and its aerodynamics especially the undercarriage part, Same thing was done on the new nissan GTR
FYI. Holden HSV just revealed a few months ago, thats HSV will get under cc on next 2010 production to improve aero and fuel consmp.:o
Thanks for sharing DMX!
Th use of undertrays and diffusers work on similar principle to a wing. it makes use of the fluid properties of air conforming to Bernoulli's equation p1v1a1 = p2v2a2.
The lower your car is to the ground, the narrower the gap is and thus the air must speed up to maintain continuity and thus low pressure is created. That's downforce.
As for spoilers on the back of cars? There's two distinct things you can have and a lot of people get confused over the two. There's a wing and there's a spoiler. A wing is a separate element that actually produces downforce because of the pressure differential over the element. And there's the spoiler which does exactly what its name implies. It spoils the airflow over the top of the car so that the car body itself doesn't act like an airfoil and produce lift at high speeds. Anyone notice how your steering gets kinda floaty when you're going fast on a car without a spoiler? That's what it prevents.
I didn't realise it would have an effect of aeroaccoustic dampening; how much quieter is it inside now withe the undercarriage covers?
Also which model is this usually fitted to? JDM Civic Hybrids or all Civic Hybrids?
how much did that set you back? looks nice tho... very clean
you most definitely right about making the aero dynamics better and reducing the air traps...
good stuff :thumbsup:
ahhhh...but was it worth it with the amount of money u spent on it?
If it seriously reduces noise, then you really can't put a definitive value on that. DMX might really appreciate a quiet drive. But I don't think the fuel consumption figures will tumble.
Yeh, it'll be good to know how much noise reduction it really does vs. the cost.
I appreciate a quiet drive too :)
On the topic of ride comfort... Does anyone know which spring gives the best ride in terms of comfort (not concern about track) ? Cause I find the stock suspension abit too stiff to my liking.
Read in a Euro thread (and other forums) that the Tein Comfort Sport coilovers gives a very comfort ride:

Just wondering if there're other cheaper options...

http://media.gm.com/intl/opel/en/new...elease_698.htm
The following changes were made to cut aerodynamic drag still further: the Corsa Sport's roof spoiler and side skirts were adopted along with large-diameter wheel covers that guide the air flow smoothly past the wheels. An undercarriage panel improves air flow underneath the Corsa, and the size of the cooling air ducts was reduced so that less air flows through the engine compartment.
http://www.autospeed.com/cms/A_108675/article.html
It's interesting to see the airflow passing from the side of the car to its underneath area - despite the wide side sill panel. This flow may be promoted by the Porsche's flat undertray.
The 993 twin turbo has a factory quoted Cd = 0.34 which is a quite good for a car that also sticks to the road at high speed. The drag coefficient probably benefits substantially from the car's full-length flat undertray.
http://www.autospeed.com/cms/A_108676/article.html
Rather than letting the air that has passed through the radiator simply spill out from the engine bay, here an undertray with specific exhausts has been used. The air is guided to emerge from two openings in the tray, whereupon it again accelerates in speed. Note the slower speed in the wake behind the car.

FYI. New Hybrid camry which backed by Aus federal Gov
Every line and angle of the Camry is aerodynamically honed - reaching a pinnacle with Camry Hybrid's 0.27 coefficient of drag - while Camry SE employs Toyota's F1 technology on the undercarriage for enhanced stability at higher speeds.

I'd like to qualify what I said. I didn't say that it would have no effect. I said it would be negligible.
You've posted a range of articles that give us a heap of different information. I'm not too sure what kind of a point you want to make here. Are you trying to convince me that the airflow across a Porches separates and recirculates in various places. Or are you trying to tell me that improving your vehicles aerodynamics improves fuel consumption numbers. Perhaps you're trying to tell me that your undercarriage cover acts just like the undertray and diffuser assembly of a Ferrari Ezno and gives you downforce! And these very fancy-looking CFD images you've given really don't support your point much at all...unless your point was that the Honda Civic is completely different from a Mercedes E-Class.
Altogether I think that you were trying to say that improving the aerodynamic characteristics of the car improves performance. That's correct and I'd hardly disagree else I wouldn't end up with a job (I'm studying Aerospace Engineering).
My original point was that I didn't believe the improvements made to your car would offer large performance increases. The best piece of information you offered was the two numbers at the bottom. The Cds for the two cars.
Overall the Civic Hybrid experience a grand total of just shy of 6kgs of drag less than the stand Civic at 100 kph.
But then your car isn't the standard Hybrid either. You've got a wing on the rear and some pretty schmick wheels. Those aren't going to have the same characteristics as the Hybrid. You therefore can't claim the whole .04 decrease in Cd.
My main point is that unless you cruise everywhere very fast, the fuel savings you'll see are negligible. But even if you weren't after fuel savings, but increased downforce. I'd wager that the increases would be tiny. The under carriage tray wouldn't promote pressure gradients in order to produce downforce.
in the end its dmx car, so he can do whatever he wants :p
ppl still put stikcers, type R emblems, decals, etc on their car without any effect right?
I thought stickers made ur car go faster...
no actually it slows down the car, its add extra weight to the car :p
i removed the civic and sport badge and my car sprint from 0 to 100 in 1 sec! :pQuote:

if you can read the chart : cd 0.25 : to reach 100kmh need 10kw power
cd 0.35 : need 12-13 kw power. means the lower cd, lower power needed, and as result less FC.

Fourth, the ground vehicle has fewer degrees of freedom than the aircraft, and its motion is less affected by aerodynamic forces.

I really don't won't to continue this argument in public. It's just dick waving and makes both of us look like twats. I'll PM you my IM address and I'll explain my points without internet-ego inflating our points.
in the end, the price for what dmx paid in my opinion does not worth the money for what he will get. i can bet the fuel savings will be really small unless he drives really fast all the time and by doing that it will confume more petrol anyway. again, like the rear wing, its for race cars driven on race courses and of minimal use for day to day driving. at least the wing make ur car look good but u cant even see the cover...
yeh its a waste of money mod, but so are alot of mods, people still do em coz they like it. let it be.

DRIVING TIP
NUMBER 26
27June 2008
Save pounds at the pump
As soaring fuel prices continue to hit the headlines, motorists cannot fail to be interested in ways to get the most miles out of every tank of petrol.
Regardless of your choice of vehicle, there are techniques you can use to save fuel and at the same time minimise your impact on the environment. These techniques are part of the IAM (Institute of Advanced Motorists) course, which has delivered eco-benefits through fuel efficiency methods since the IAM was established in 1956.
Ask yourself: "Do I really need to drive?": Short journeys that are generally less than two miles cause the most pollution and are inefficient in terms of fuel consumption. A straining cold engine will produce 60 per cent more pollution than a warm one. Walk or cycle where possible instead.
Plan your route: Take the most direct route and go at off-peak times if possible to save fuel and time. Sitting in congestion means you are often doing zero miles per litre. Consider car sharing, Park and Ride schemes or public transport.
Have your vehicle serviced regularly: Inefficient, under-serviced engines can reduce fuel economy by 10 per cent or more. Catalytic converters are environmentally friendly - but only if they are properly maintained.
Check your tyres: Correct tyre pressures reduce wear and helps fuel economy. Under-inflated tyres need replacing more often (itself an environmental problem) as well as being dangerous. Make a point of checking them at least once a week.
Obey the speed limits: Try to ‘feather’ the throttle when you reach your cruising speed. Doing 56mph uses 25 per cent less fuel than 70mph and a smoother driving style can bring significant fuel saving.
Reduce the drag factor: Remove roof racks and carriers when they’re not in use as well as unnecessary boot luggage and heavy accessories. Driving with the window open and using air conditioning increases drag and lowers fuel economy, so use the vent settings instead.
Buy green fuel: And use less of it. If you get stuck in traffic, switch off the engine. Find out if you can buy low sulphur diesel (city diesel) or cleaner petrol (low sulphur/aromatics) locally.
Use “accelerator” sense: Save fuel by planning ahead and reading the traffic in advance to gently join a queue rather than braking suddenly as you hit traffic.
Reverse when you park: The engine will be cold and at its most fuel inefficient when you start it. If you can drive away without having to reverse when the engine is cold, you will save fuel and have better visibility.
Watch your levels: If you fill your fuel tank up to the brim, you may be carrying around additional fuel which in turn means that you have more weight on board than is necessary and this will itself reduce fuel efficiency

My point is just this. Unless you spend a lot of your time driving faster than the speed limit, you won't see significant savings in fuel or an increase in performance.
The proof lies within the data you provided. How long do you spend driving at 100kph+? At 100kph, from the graph you've posted, there's less than 3kW of power difference in the power required. The Civic isn't exactly a powerhouse, but it can spare 3kW.
That's all my point was.
how does" ...drive away without having to reverse when the engine is cold" help FC??
If you reverse park, when you start the Car, you can drive it off immediately. Instead of wasting time reversing it while the engine is cold and burning the most fuel.Quote:

Come on, enough with the flaming.
People have these forums so they can show and tell their mods that they are thinking of or have already done.
Now what DMX has installed a undertray which may, which may not decrease drag at a rate which is noticeable at human instintcs but who cares....
We all mod for fun and we all know the feeling of getting that new mod which we are going to install on the weekend regardless on what it is.
Thumbs up to DMX for being a pioneer of FD civics and thanks for the start button and facia you have supplied me =P
^^^ Absolutely agreed!
This is such a wonderful thread for FD owners to share with and learn from others. DMX for one has been a great contributor to everyone here and what others have done will no doubt discourage alot of ppl sharing their mods. DMX didn't ask you to pay for his mod yea? So lets all appreciate other's effort and move on!
AAHHAHAHAHAHH FOB:pQuote:
