wrx and evo rivalry has been there for a while. i'm not surprised... ah well better than a commonwhore than cant even move fast in a straight line [sweatdrop]

Let's remove our suspension n drive w/o it.. Wah, the feeling darn shiok man! [laugh]

 

i think it's possible right?... wonder how the handling will be.... [hur]

 

even the small 1/10 or 1/8 R/C cars have a full coilover setup... can change the springs, ride height, dampening, shock absorber fluid... etc. damn cute

wah a bit hard... for power increase per $, TC then SC then nitrous.

 

Intercoolers do not increase power although they allow you to make more power safely.

 

How do you compare suspension when it does something totally different to the rest of the mods??

 

Upgraded suspensions vs stocky soft suspensions made alot of difference for high conering speeds, as well as sharp corners IMHO. [thumbsup]

 

For example, two significant stock cars, one with a Low Boost turbocharger, & the other without but had a good set of suspensions may not loose out to the turbocharged car in the race track cos conering speeds is also very important during a race in order to take home the trophy.

It does. First thing that gets upgraded for me is suspension. What i meant was how do u compare a suspension mod to a power mod.. [dizzy]

However, I wish to point out, before we proceed, that the internet has plenty of information for research but there are also a lot of junks. Viewers should decides for themselves what information they read is CREDIBLE, and what are junks. This is because most of our references, including mine, are based on articles published by companies and individuals on the internet.

 

Agreed. Let's see what you posted.

 

Basically the few variables involved are:

 

1) Pressure

2) Volume

4) Temperature

 

These are the variables of Ideal Gas Law, whereby:

 

P1V1/T1 = P2V2/T2

 

P1=INITIAL PRESSURE

V1=INITIAL VOLUME

T1=INITIAL TEMPERATURE

 

P2=FINAL PRESSURE

V2=FINAL VOLUME

T2=FINAL TEMPERATURE

 

For argument sake, imagine the conditions as below:

 

Running 1 BAR boost before intercooling = P1

Intake Air Temperature before cooling is 150 deg C = T1

 

After intercooling, let's assume there is a drop in 40 deg C = 150-40 = 110 = T2

With Volume being constant = V1=V2

 

Given P1V1/T1=P2V2/T2 --------(1)

 

SUBSTITUTE P1=1, T1=150, T2=110 INTO (1)

 

V1/150=P2V2/110

110V1=150P2V2 --------------------(2)

 

SUBSITUTUE V2=V1 INTO (2)

 

110V1=150P2V1

 

DIVIDE BOTH SIDE BY V1

 

110V1/V1=150P2V1/V1

110=150P2

 

THEREFORE P2 = 110/150 = 0.7333 BAR

 

This concludes that in order to achieve the same volume of air into the engine after intercooling with a drop in 40 deg C, the pressure after intercooling must drop to 0.733 BAR.

 

Let's assume a better intercooler is able to lose 70 deg C compared to the previous example, while all other remain the same.

 

After intercooling, let's assume there is a drop in 70 deg C = 150-70 = 80 = T2

With Volume being constant = V1=V2

 

Given P1V1/T1=P2V2/T2 --------(1)

 

SUBSTITUTE P1=1, T1=150, T2=80 INTO (1)

 

V1/150=P2V2/80

80V1=150P2V2 --------------------(2)

 

SUBSITUTUE V2=V1 INTO (2)

 

80V1=150P2V1

 

DIVIDE BOTH SIDE BY V1

 

80V1/V1=150P2V1/V1

80=150P2

 

THEREFORE P2 = 80/150 = 0.5333 BAR

 

This further shows that a more cooling intercooler will have an even higher drop in pressure when more heat is dissipated.

 

OK, stop.

 

Your flawed calculation is based on the idea that volume of the gas remains constant given that there is a drop in temperature. By Charles Law, you CANNOT do this i.e. hold the volume constant yet lower the temperature. [whip]

Read the thread title and the original post. It says "performance mod", not "power mod". Since suspension does help a car handle better, it is considered a performance mod.

Thanks for pointing that out THUMBS, as I was about to do that too. [thumbsup]

OK replying to my own post since MCF doesn't seem to allow editing of post. Mis-read the part about constant pressure. My bad. [rifle]
