any suggestions?i tried to put on factory fan cover onto radiator and there's not enough clearance and the fan would rub against the cover.need to go for roadworthy this week need help thanks

do you need a fan cover around the fan?

ive never had one, had no issues with rwc

Have your trimmed it down?

If not, buy a radiator that fits?

You dont need 52mm for even a moderately modded car

ill go for rwc tomoro see if i have any issues hope not

i think you would have more issues if you cut your blades than having a fan cover on, you should be fine because the fan cover has nothing to do with handling on the road.

if you cut your finger off on the fan while working on the car its your fault and cant cause any hard to other drivers, unless of course you work on your car while driving on a free way, and your hand gets caught in the fan causing you to hit other cars.

The fan will be practically useless without a shroud.

not true

are you suggesting a ceiling fan dosent suck hot air down when set to winter mode?

same situation, different location

Fan will be significantly less effective without a shroud, as air will take the easiest path, and that will be from its periphery rather than thru the radiator

OP - I slotted the top radiator mounts so that the rad is pulled as far away from the fan as possible, instead of flopping around. I then secured the shroud to the rad and it doesnt touch.

lol having this issue atm with a car I have here. We ended up getting it to fit but only without the shroud and then it ended up throwing the fan through the core. Yay fun times. It was a piece of shit X-cess brand, 52mm core. Certainly does not fit like they say it does

Why would the fan draw air through the radiator when it is much easier to suck the air from AROUND the radiator (the path of least resistance)?

There is a reason that you shroud fans, particularly when you want to draw air THROUGH a heat exchanger.

Anyone advocating NOT using a shroud, should share their crack with the rest of us.

Yeh the only reason we didn't use the shroud is because the blasted thing wouldn't fit with it on and the a/c is all removed. There aren't many options for the air to travel AROUND the radiator rather than through it. I know drift cars with the same radiator without cooling issues but it's a prick of a thing in a street car in stop start stuff

Wasn't having a dig at all and I'm not talking about it pulling air from the front of the car around the radiator but more that without a shroud it will just pull engine bay air from between the front of the fan and the radiator, and blow it out the back of the fan, as opposed to drawing air through the radiator.

On a track you have lots of airflow (less in a drift car because you're sideways but if you have nice big, properly designed air dams it will be fine), on the street, as you said in stop start stuff, it's going to be terrible and the temps will go through the roof!

IMO you're (and not meaning you Elite, more of a generic term :D) better off running the stock radiator with a shrouded fan than a bigger radiator with a non shrouded fan. Drifting or dragging with a big radiator and non shrouded fan will be ok as the water is just a giant heat sink, couple of laps or a run down the strip, then cooling off in the pits, no worries!

On a street car, as soon as that radiator gets heat soaked, the non shrouded fan is going to do 2/10's of fk all to cool things down, it will just move hot air about the engine bay.

If the engine fan won't fit, then get some thermos with a nice shroud.

Haha yeah np I didn't think you were anyway. I probably worded it wrong.

And yes, definitely +1 on pulling air from the engine bay. It's usually only a problem in traffic though as the air forced through the front of the car will outweigh the need for a fan anyway. Shroud is definitely better off in place rather than without though.

im not saying that its just as efficient, but the fan blades are designed to suck air from in front of the fan. if you hold a string to the side of the fan without a shroud, i bet the string wont get sucked into the side of the fan.

ive said it once, ill say it again, its less efficient, but not useless

imo

The fan doesn't sit flush with the radiator..

same situation, different location

Fans dont actually suck hot air down... they draw it up to the ceiling, push it across the ceiling and back down the walls :down:

And its a completely different situation, as that fan isnt actually trying to draw air through anything. Its just moving it around.

I think its been proven more often than not that in Australian conditions, shrouds are a MUST for the clutch fan in traffic.

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
