remove 172 aircon

[jaym1806]

hi,anyone used a shorter belt on the 172 to do away with the aircon
been told you get a gain of between 7 and 10 bhp

do i just use a cup aux belt?
cheers

 

[jaym1806]

forgot to say will the climate control still work ok apart from the a/c lol

You'll be needing the cup belt, cup alternator, cup alternator brackets, some niftyness with the PAS pipes to get rid of it. As for expecting 7-10...........no

the guy at a local garage said to use a smaller belt and redirect it and i could use the same alternator and just leave the a/c unit whare it is

 

[jaym1806]

any idea of what gains people on hear have got after removing the a/c

 

[Gttnutter]

I dont run aircon but the pump is still in use via the belt, its just been disconnected,

I was looking to get rid of it altogeather but after some search on here i cant be bothered to run the cup alt bracket and alt

Its just more expense at no gain

if you just changed the belt so it didnt go round the a/c pulley would that not free up abit more power

Most of the "gain" from removing the Aircon, comes from removing the weight though.

 

[172Ben]

You may get 1-2bhp? But as said its more about weight, and cheaper cambelt changes is what im looking at.

You cant use the same alternator iirc? Has to be the cup one?

But 7-10 bhp, i wish!!!

is the unit itself quite heavy?does the heating work ok when you remove it

 

[Bazzon]

The aircon system is heavy thats why the track goers remove it, also as said above it makes cambelt changes easier.

The Fans still work. untill you rip the full heater matrix out )

And u need a new alternator as well as all the brackets.

Ideally need a cup alternator but all that's different is the outer plastic casing iirc? K-tec managed to modify a standard F4R alternator for my removal

You save about 7-8kg I think (With aircon removal)

The brackets on the cup alternators are differently placed from the normal ones. on the cup i think they are 180degrees apart and the normal is 130degrees

 

[Nick r26r]

what do people do about the power steering pipe as the sensor on mne hits the radiator with the cup altenator on !!! radiator is currently in pisssseeeddd at the moment due to it not fitting properly

 

[saltyhair81]

it needs to be rerouted, I can take a picture of mine tomorrow if you like

 

[Nick r26r]

yeah that would be great ,

I'm a beleiver in doing away with AC. But seriously.

Car: monaco 172 turbo

Just up the boost??

 

[172Ben]

Have you bent the pipe salty?

 

[Nick r26r]

can you bend the pipe without it breaking, or just take the sensor out of it and weld it up , or will the power steering light stay on constantly

 

[Cro]

It can be bent somewhat but just be careful, its not alot and splits very easily

 

[saltyhair81]

Have you bent the pipe salty?

Yes, It's been on for about 5 months now without problem. Just got some silcon and foam over it to make sure initially. Tis fine though. Like croc says it's fairly pony metal but doesn't need to be bent much. At least not on the Ph1, not sure if theres any differences. Speak to K-tec otherwise. They offer the entire package

lol thats an idea

 

[jaym1806]

would it make much difference if i just got a new belt and missed out the a/c pulley

 

[Nick r26r]

any pics yet saltyhair !!!

 

[chrispy.clio]

I re routed my AC pipes.

Not sure it this pic is of any help

 

[Nick r26r]

cant really see much mate ,

 

[chrispy.clio]

Sorry thought somong wanted to see the rerouted pipes.

 

[172Ben]

power steering pipe, not air con pipe

 

[chrispy.clio]

power steering pipe, not air con pipe

lol reading fail once again by me

 

[saltyhair81]

Haven't had a chance today sorry, will put some up tomorrow

 

[saltyhair81]

Hope this helps

 

[Huffski]

why do you need a cup altenator when removing the a/c why cant the standard one still be used

 

[Nick r26r]

it can be , the cup altenator is just got a shorter belt so will make it rev a bit more freely ,

 

[Nick r26r]

what is different on the cup to the 172 then ??? rad or power steering pipe's ???

 

[Fred@BTM]

alternator, PAS pump location, aux brackets, PAS pipes
