Hot Weather

[R32Abuser]

Ive notice in the last couple of hotter months, my car in traffic (heavy peak hour), when the temperatures in excess of 34, all of a sudden starts idling like a rotten piece of crap (heaps low idle like 400RPM) and taking off is rediculously doughy and sluggish. Then ill get home lift the hood check all the cooler pipes etc and they will be rediculously hot (as to be expected tho) and the heat shield will be "tinging" (cooling metal) to all buggery. Im just wondering if anyone else gets this, or what i should do to help this, or if turning the aircon on to get some additional airflow in will help ( i kno this helps in other cars as it switches on the aircon fan which draws cooler air in to the engine bay).

Cheers, David

400rpm idle is extremely low. but everything else is normal and expected on hot days. turning on air con makes it worst.

yeah my R34 doesn't like it much either .... but is fine as long as the car is moving. But still, I am going to take off the stock crank fan, and put in a heavy duty thermo fan. I am also going to rig up some sort of fan on the air conditioner radiator/compressor. When my car gets too hot while idling, the air conditioner actually turns off (hot air comes out) - I assume due to some over-temp safety mechanism. If I get out and pour some water on the radiator and air conditioner condenser, the air conditioner fires straight back up and works a treat for a while - the car seems to run better for a while too. I am also going to rig up a big water misted to spray the radiator for really hot days like I had on my S15.

Andrew,

My A/C also used to cut out. I replaced the stock condenser fan with an aftermarket 14" fan that blows a hell of a lot more air.

And the best part.. No more a/c cutting out.

cool, thanks Joel. Yeah I am thinking I will grab a JustJap alloy radiator, Davies Craig 20" thermo fan, bigger condenser fan, Davies Craig trans cooler (already have, just have to fit), and oil cooler (already have, just have to fit) then I will be all set for summer

I bought my 14" thermo from atracing on ebay.

From memory it was ~$80.

The fan wasn't a straight blade it was a curved blade.

Looks identical to this one.

What ever you get be sure its a curved blade fan, they push a lot more air and they are quiet.

Those justjap alloy rads are a bargain.

put the heater on, that helps if u can put up with the extra heat in the cabin. it draws the heat from the cooling system so in theory it draws heat from the engine which should make it run slightly cooler.

dont forget coolant flush if you havent already, car will love you for it.

with my car, heat naturally goes into side the cabin where the foot area is. and i press the recirculating air button so that it blocks it from coming in.

Hmm my 34 doesn't seem to cope to bad in the heat.

My little pulsar gets pretty damn hot though. Plus it has no air con

[Nightcrawler]

thanks for the link Joel! That is exactly what I am after.

what about the affects of different temp on boosting.

I'm only mentioning this because I have heard that thick/thinner air accompanied by the factor of its temp can potentially damage or over power a car that is not set up correctly or doesnt have the appropriate management systems in place.

MMM, i would be worried bout anything else, but the idle was casuing the only real concern for me. Ive just set up a new CAI for the 32 hopefully to lower the intake temps marginally, guess we'll see. So no one has had the idle problem tho??!

And really the only solution is to get a bigger thermo fan or the like?

nightcrawler = used to have the pewter s15?

if so, this is andy, i had the R33 GTR (midnight blue), with Matt's 33 gts-t

i see u're still on the forum

we havent been on here for like 4yrs now..time just flew

howz the family?

[Nightcrawler]

ahh how you doing mate? Yes it is me, and I still have the pewter S15 (want to buy it? lol) .... yep things are good - the usual : work hard, play hard - we have just returned from a week in Singapore, I spent a week in New Zealand skiing in August, and we spent a month in the USA last September. Work is good, but busy and no kids on the horizon just yet (thank goodness) .... how about yourself? Did you sell the GTR?

i remember last seeing you (bout 3 yrs now @ bp) with a female and your car had twin pipes then you dissappeared.
