Radiator Upgrade In R33

[Bunta]

dont see why they would not.. be on drivers side

do it my way dnt think about it ull be right the temp switch regulates it. all good.

I dont think that will work Marki, I think that the switch yu are talking about works the tiny fan on the front of the raditor and doenst in only come on at some sill temp like 100+ degrees?

worked on the RB20 silvia.

should work.. thought it was kick in at 87degrees.

why not just have the thermo wired to turn on when the car turns on ?

Cause you need the water to actually heat up...

If you run your motor to cold you can do damage and use more fuel, if you run to hot you can do damage and of course blow it up...

On top of that thermo fans, electric one are rated by how many hours of operation they can handle.

Like Craig Davies fans are some of the best on the market, rated to 50,000 hours of operation. So constant running the fan motor will lower its overall life...

Make sense?

thats cause u built it col lol..

"Typical white boy name, you know hat im saying"

Reason its was too cold then too hot...

Well these fans come with a simple temp control unit, it reads the temp of the water entering the radiator through a simple copper wire.

You then adjust the resistance using a simple variable pot dial to suit when the fan cuts in.

So in winter the water cools more rapidlly hence the fan cuts in and out so much that it gets the the point where it can actually damage the fan.

So you need to adjust the pot to suit winter/cold condition.

Then if you leave it, in summer the water gets to a point where its to hot and the fan seems to be just running constantlly. So you need to adjust it down.

Remember this entire time while the fan is running, these things pull a solid 15Amps which is quite a load on your battery and electrical system.

I hear all the time people say, ditch your fan as you loose 3-4hp, well the load that the electronic fan creates on your alternator is probablly more than 3-4 hp...

Make sense?

That tiny little fan infront of the radiator is to assist the air con and has nothing to do with the temp of the engine...

It keeps air flowing over the air con core while stopped at traffic lights and so forth...

Many re-wire this fan for other purposes but its job was designed to cut in when the compressor cuts in and has a relay driven from the air con comp circuit...

lol i love lines from f+f lol hi5 col.

yep correct the fan is the a/c one and sits infront of the a/c behind the front bar on passenger side.. good use for the cooler

was at one stage gonna wire up 2 12inch on the back of the cooler core for a lil less heat soak that and water spray but im too lazy.. water spray comes soon but

[Col-GTSX]

Water spray or Cry O2 do a far better job than any fan can do...

The tests have been proven many times over...

I was at willowbank the other night and a guy got a CO2 fire ext out of his boot and sprayed his intercooler before going on...

He put shit all over the place and the marshalls told him his not going down the track like that and to clean his mess up...

You see it was not a c02 fire ext, it was actually dry chemical...

[markimak]

wtf.. wat a toss.. i was told that sprayin my cooler on the strip would not be tolerated lol.. they didnt catch me

im keen to go for another run soonish.. wanna see what i can peddle my 180 to.

buy an evo...waterspray from the factory ha ha

[Oblivion]

dude wtf are u on about getting rid of the shroud the only reason u keep the single clutch pack fan is cause the shroud draws all ait to the fan n00b..

u dnt need a controller RB20 have a thermo switch sensor on the radiator. green plug wire it to ther. i run single 16inch on the RB20 silvia. with no a/c and ohh guess what its farkin quicker than a GTST.. and has more stable water temps than my 180sx.

what the f**k man, you talk about how good drifters are all the time go round and see how many of them are running no shrouds with standard clutch fans, and tell them it wont work.

and i dont think were are talking about an rb20.....so stop talkin about them.

and for those who want to create less drag on their engine, then look at putting a flexy bladed fan on in place of your big plastic one, they are genius work. pull shit loads when your stand still and less and less when you are moving faster and faster....genius, alot of dragsters use them. oh and that wiegh fark all so have stuff all inertia.

[Ryan.R34]

I've had my 2 x 12inch thermos on Alloy rad for a months now, My original fan had a chunk out of it and original radiator was looking a little sad, thermos kick in at 83oC and runs no problem until you get a very hot day and the temp goes up sitting in traffic 97oC I noticed, I made a mockup shroud to test it out and the shroud worked, I didn't think it would do shit but to my surprise it kept the temp down 81 - 87oC driving and didn't touch 90oC in traffic. Now to get my bro inlaw to pull his finger out and make me an alloy shroud.

I noticed revs came on alot quicker of course with mech fan gone, can only imagine you also lose a little touque maybe, I'm no mechanic.

MOST IMPORTANTLY The setup looks good but if I could save someone all the hassle don't bother, just get yours fixed or replaced.

lol, thanks for the many informative replies guys, has amde my afternoon at work more enjoyable. hahaha. shroud or no shroud, i just want a radiator that isnt cracked

same with sti

come on u knw this.. reason being is a drift car is at full bore for 30seconds or so. if that. in that time ive seen oil jump 10degrees just after a run. and not to mention they get 2/3 of normal airflow due to bein sideways.

ok why would a drifter want lighter pulleys and less shit on the engine but retain a std flywheel..?? they need it not to rev quick but to maintain a balanced rev. come on rohan u drift u should knw this. light weight pulley bits on drag cars yes.. drift cars no.

and i was refering to the RB20 as it uses 1 thermo and tellin them about the switch i used bish..

shroud.

try with and without use ur pfc to trace temps.. u can buy me a drink if im right with the shroud.

and ryan i love ur set up did u fix the temp sensor thing i told u about months back>

[Strik3r]

still havent really gotten a response to my question.. sounds like i should try and get a shroud made up or a bracket mounted for the old shroud ? can i get away without one or is it risky ?

[markimak]

u can do what u like. i recommend a shroud and u will find out when u sit in our shitty qld traffic under the qld sun with the qld temps of 40+ do u treasure ur engine.?

[shanef]

both the evo and wrx are ghey's

dont forget...TEH GTR CAN NEVAH LOSE!!!1!!11!!

[Spooner]

shroud.

>

ok will do. i have been cruising around nothing above 100km/h and it has been keeping below 95 with cracked radiator. so we know how it goes cracked and will see how much better it is with new one and shroud or no shroud. hahahaha

[markimak]

both the evo and wrx are ghey's

dont forget...TEH GTR CAN NEVAH LOSE!!!1!!11!!

remember last dyno day how that evo9 pulled 200+ from pod and cat back..!!!

i think we have a new winner GTR is bein caught up

so marki, wats the new project? sr into an evo?

P.S teh gtr can nevah lose!!!111!!!1!!

GTR.. u own a GTST lol

nope. future projects lined up for next year are as requested by people.

RB25neo into 180sx for sean.

4G63 into a eg/ek civic

1JZ into 180sx

and a few SRs into silvias.. oh damn gonna be difficult.

the 4g63 should be a good attempt.

and the VR4 4G63 is running. but got a leak from timing cover

never ending problems with building cars lol. u agree. got ur head sorted

[WazR32GTSt]

if youre going to get an aftermarket radiator, probably worth investing in an aftermarket temp gauge too so you cna actually see the temperature of your cooling system, rather then the arbitrary gauge that nissan provided us with that is good for nothing...

[Strik3r]

im curious to know at what tempreature that temp guage starts to move from its happy 'middle' position.
