Do You Have Air Con On Your Car?

[Amaru]

Ditched my aircon, but was more of a neccessity to fit the intercooler in nicely. Could have moved it but I never used it anyway (I dont even think it worked) so out it came!

[CameronBNR32]

the same as Amaru, I converted to a big single turbo, and the air con was directly in the way to run piping.

Never used the air con anyway, wind ya window down

How do you plan to achieve throttle response? Stop being so secretive

[mad082]

i think he his plan is that by removing the aircon he can run shorter cooler pipes so he has better throttle response.

what you have to take into consideration is that if you have the cooler pipes too short you tighten the bends, which makes the air have to change direction more suddenly. if that pic is of the setup ypu are trying to shorten, then there isn't much you can do before you start compromising air speed.

another option would be to fit a smaller cooler. removing 6 inches of cooler will reduce the air volume by more than removing 6 inches of piping.

Not being secretive.

Untimately the aim is to keep the intercooler piping as short as possible and with as little bends as possible.

We can play around with intercooler sizes, end tank designs... the sky is the limit.

At the same time using chinese factories to keep the prices down but keep quality up to a good level (as seen with the bar and plate cores that people are using in 400+ rwkw cars).

We recently did a project for the VL guys which can be seen here: http://www.calaisturbo.com.au/showthread.php?t=78364 (the aim of that project was to keep the intercooler hidden aswell as avoiding any holes being cut in the chassis)

I'm not talking about losing the aircon due to the power loss. I'm talking about losing the aircon for space in the engine bay/front of the car.

dude, SR20 is GIVING you room if your not using an RB20.

room should be your friend.

Keep the aircon - or suffer in the heat (in silence)

300rwkw - never going to get rid of my aircon. I dont care what i have to do

And if you notice a throttle difference with an extra bend or two, i'll hand you a medal

Cause you wont notice it at all IMO.

[Rolls]

No way I would ever remove it. Heh even if it was a track car I would want it.

[Busky2k]

I'd try to keep it at all costs. When its a 40C day and your ass and back is glued to the seat with sweat, I'm sure you'd be crying out for the aircon!

You think that there wont be a noticable difference going from a Hyrbid style intercooler kit to the one I'm using in my R32? (or any other cooler kit that's remotely similiar)

I'm not talking about making kits for an SR in the skyline range as there is clearly enough room (as seen in my R32), but I'm asking to see how many people are actually using their aircon and how many people would lose it for a setup like this.

With the SR range of cars, it's not necessary to lose your air con.

umm. the ac compressor turns of at any major load any way

just the extra heat through the radiator youve gotta wory about. its gives NO LOSS OF POWER at all.

so just bask in the nice chilled enviroment lol

We're not talking in terms of power loss from the AC compressor.

We're talking in terms of space in the engine bay.

woops my bad :s

do a search for some of the many posts by sydneykid regarding shorter cooler pipes and how removing 20cm of pipe is going to make no difference, but to do the maths

at 3000 rpm and zero boost / vac your 2.5L engine is consuming 3750L of air per minute or 62.5L per second

assuming u save 20cm of pipe and that its 2.5inch pipe that will have a volume of approx. 1.5L in that pipe.

so your engine will consume that air in 0.024 of a second, now add boost etc....to the equation and is it worth sacrificing your aircon for 0.024s of throttle response

sorry if this is wrong but as my understanding goes this is how it'd work

20cm's of pipe?

You'll be losing around 2 meters, aswell as around 600+ degrees worth of bends.

[RNGTR]

Still have my Air cond, works perfect.

Thats still only .2 seconds

[GKTECH]

Thats still only .2 seconds

In theory, pollsibly...

One of the drift cars we used to sponsor (180/s15 front) had a FMIC install, it's now running a V mount setup and the difference in throttle response is incredible!! I can't time it, but you sure can feel the difference.

If the RB guys aren't interested in these sorts of kits, that's not a problem. We'll just make them for the SR's.

I don't understand the concept of a vmount setup?

Any crude diagrams or picture examples?

What I really want though...

An FMIC setup that uses the std piping route. I would like an fmic to fill the whole front bar inlet as to let as much as possible air pass through to the radiator.

Currently as can be seen the end tanks block of a considerable amount of the front bar.

The core i'm using is apparently a spearco bar/plate core 450x260x90 *from memory* with sligh off centrally located inlet/outlets. being center located makes it easy for the hot fmic inlet pipe to do a 2 x 90 degree turns to enter the fmic (drivers side). It runs crappy 2.25" piping.

my car is fitted with a greedy item, runs std pipein route and fills entire front bar,i have remooved my air con however it did not get in the way,

I don't have any pictures handy, but the overall idea is to have the radiator sitting on a 45 degree angle and your intercooler sitting on a 45 degree angle, the overall the advantage is that the pipes are shorter, and neither your intercooler or radiator are getting less air flow. The disadvantage to this setup is heat soak.
