Breather Tank
 

anyone out there have any input in this product for our rx8? dun know if it works on our car but apparently it works on airtrek turbo. my fren had it installed in his airtrek and the car water temp used to be hitting 100 deg c after only 1 lap at sepang now never go more than 80 deg c....very impressive i must say. myself just came back from sepang n my car water temp went all the way to 120 deg c with defi reading. ( few hard laps though) kinda worries me now... any idea if it is normal ? Or should I bring it back to agent to have them sort it out ?

Also i called garage R and they recommend to either change the whole radiator or thermostat .??? Any suggestions?

I dont see how a breather tank can improve water temp. Changing to a better radiator will help on track. 120 deg is too high for water temp. I think for water temp the norm is not to let it go above 110 deg. For oil is 120 deg.

thats the thing my fren have been having prob with his water temp with his airtrek and only after installing this kinda breather tank it apparently solved all the prob and the temp neva goes more than 80 deg c. Thats why I am asking if anyone had it a go with it with the Rx8? If not wat will be the best option for reducing the water temp?

there is no link at all between a breather tank and water temp.....

Get one and put it on your car... That's the best way to tell....

I am told breather tank does help a bit in lowering water temp..... Many RX7 have breather tanks....

Ha ha .. i like your style lennon..... so wat have you done to your car so far? do you also have the same prob with water temp? anyway when will be the next malaysian open track day ? really feel like joining the malaysian open ....

Breather tank is kinda cheap and it's work on many cars....... If you are not satisfy with it, just sell it to others......

When i first get my car, my frens who have RX7 recommended me to install one....... They're all talks miracle about the tank.....

For open track day, better check this web www.malaysiangp.com.my......

Breather tank -or more correctly "oil catch can"- is used to collect blow-by oil that would otherwise recirculate into the engine through the intake.

Like coupe07 said, there is NO correlation between oil/water temps and an oil catch can. Through some bizarre way, the can *could* affect oil/water temps by 1 or 2 degrees, but certainly not to the extent that you are mentioning. If this is indeed so, something is most definitely wrong with the turbo installation....

Dude I think they are two diff thing...... oil catch tank and breather tank is off diff usage. Breather tank is actually the one you install to your radiator to remove water bubble during high rev and thus reducing your water temp. Oil catch tank is as you said .... something to do with the environment.....

If a breather tank does indeed do what you say then it could possibly cause a temperature drop since it works sort of like a underdrive pulley to prevent the bubbling up of coolant for better heat transfer, no?

We know what we are talking about here....... Oil catch tank and Breather tank are like apple and orange..... :)

How can underdrive pulley do such a thing??

Thanks Lennon.....so have you actually tried out the breather tank? If so does it work with the RX8? Coz if it does not then I might just pop by Mazda agent and ask them why the water temp is so high before trying some other mod to make the car run cooler....

I heard RE is coming to SG again. Maybe can get them to tune up your ecu. Those who have done it have reported lower temps all round.

Thanks for the tips.... but my car from agent ... so might want them to take a look at it first ....... :)

the rx8 temperature is high. Usual expressway driving is 95-98-100. If u r in that range, it is normal. Occasional high revs may result in temps over 100, oso normal.

Wat u wan the agent to do?? reset ecu? no use. no way to adjust the temp.

gg on track, of cos temp will go up, after whacking ur car. this is also normal. agent cun do much to decrease the temp.

as for breather tank, if the few hundred dollars can do miracles, then cooling radiator experts like ARC will go bust. Theres only so much a so called "breather tank" can do. Miracles or not........ hmm...

My bad....although I think that "AST" would be a better suited term for us ex-7 owners ;)

From what I read, I might be wrong. The underdrive pulley prevent coolant bubbling effect by slowing down the pumping action at high rpm thus the coolant flows better and transfer heat better at high rpm.

I had change my radiator but have not install the tank..... I'm thinking of getting one after the water temp gauge......

Bro, of course breather tank cannot challenge dignity of radiator....... A lot of people notice 5 degrees diff after installing it....... So no harm to give it a try..... After all, it's cheap.....
:)

after all these .... I just check some rotary tuner and apparently it is perfectly normal even if it hits 120 deg C coz anything more .... or when it is in the danger zone the check engine light will come on and takes care of itself. And about the breather tank .... the RX8 already have something similar installed to it already so installing another one won't really help. Maybe as Lennon says .. only 5 deg c. Well ... thanks for all the inputs and appreaciate all helps.

oldie thread has anybody done this mod? is there a diy out there? thanks
