Removing airconditioning - better?

[justinfox]

Hi all,

Just wanted to know if there are any real benifits of removing air-conditioning from my R32 GT-R?

My mechanic says it will help take some load of the engine? Any thoughts?

If you don't need it - ditch it.

If you use it even occasionally - I don't think the marginal gains will warrent taking it out.

I don't have one but my car came without working AC, I just took out the condensor.. 1-2kg (makes up for my speakers) - never bothered me it has no AC but I know people who would die without it.

Unless the Aircon is turned on the Aircon compressor clutch won't be engadged/locked up so it won't be using any power from the motor.

If you remove it you will save weight that is all.

Can someone confirm that? Mechanic says there is more to be had than just a weight saving.

well, just an uneducated guess coming from me. Even if the clutch is not engaged, you still have another pulley on the motor. there must be marginal resistance still. I mean it is probably so marginal that it's unnoticable, but if you don't use it, why not remove it.

i hardly use my airconditioner. when it gets hot, wind down the windows. simple. ive heard of benefits from removing it, as there is less resistance, because there is no power being lost being used to drive the a/c pulley unit, which runs off the engine itself.

There is definately a few benifits to removing the ac.

1. weight saving:

Speaking from my experience with friends of mine removing ac from their GTI-Rs there is over 20kgs of weight to be saved.

2. better engine cooling:

I'm not sure where it is on the GTR but on most cars the air conditiong core is mounted in front of the radiator, it restricts flow to the radiator and thus hampers engine cooling.

3. power

Yes, even when it's not switched on there is still drag/load on the motor, you will find a power benifit by ditching it.

The obivous downside is no ac. I thought about it a few times, but on those days when it's 35+ I want my ac working! But if you can live without it, and have a second car (shouldn't really be driving the GTR in 35 degree weather) then go for it.

the a/c is gone from the '33 goes ok, no major improvement, i do miss it as its still a daily driver! apparently it is illegal to remove a/c from a car that had it?? look that one up

[V8skylineMAN]

Sort of, its illegal to let the gas out of an a/c system......you need to get a a/c man to empty it for you....but removing it is fine...its not illegal to remove the system.

yes it is illegal to remove the system from the car. if it is a road car is must still have the defoger (that window one) or else it is not legal

front demister uses the engine coolant in a heater core, it isnt connected to the aircon circut, eg its illigal to have a bypassed heatercore, which is commen when they leak some people cnbf fixing them and bypass them

rear is electrical

Sorry mate but you definately are confused on this one....the"defogger" they refer to is the heater core......NOT the air con.....air con is an option remember....

Bingo....

Unless you're really on the edge - really want every last hp from your gtr I think you'd be mad to get rid of it - also for the resale value of the car.

I very much doubt you'd feel any difference in performance (with air con switched off) and if you reckon you do it'd be your imagination unless you're a professional race driver.

2 kg's?

Stick a couple of pairs of shoes in your boot and a box of cds on the floor - 2 kilograms worth and see if you can notice any decrease in performance.
