Overheating Issue, And Which Ecu

[ttoks]

hey all, before we get into it, yes i have searched without success to get an answer for this.

i have an R32, 320 RWKW, intending to set it up as a track car, last two times i've driven it on a winding country road winding it on a little the coolant temp seem's to creep up fairly quickly to around 110, and am obviously going to need to increase the cooling, i'm looking at a bigger radiator and installing the oil cooler i have, should these together solve my problem? what size/brand rad should i go? or is there something else i can do to solve the problem

also currently i have a power FC in the car, but have run out of play room without upgrading the AFM's, would i be best off upgrading the AFM's and keeping the power FC, or my tuner (independent motorsports in morwell) has suggesting something that doesn't need the AFM's such as a haltech might be a better options, thought's?

What kind of cooling setup does it have currently?

That's the first place to start. 110 is silly hot. Mine with nothing other than a solid radiator and properly bled cooling system etc, never gets about 70 driving around. And when really giving it curry the other week @ the Thunderdome, 5 laps i was only around 95 or so... 110 is major problem corner for the street/

AFMs aren't causing you problems, given that's all you'd need - minor tune adjustment and it's done.

Rather than starting from that start etc.

at the moment not looking for more power, so i supose the current setup should be fine, just tihnking for the future, (although thinkinga bout changing the turbo's from -5's tp -7's for better response)

for the temp, cruising around the street's, even in stop and go traffic today in the heat it never get's above 85, sitting on the freeway it sit's at around 80 by the PFC monitor on the dash, it's only once i get on a tight road and start having abit of a go between corners that it start's to heat up, first time i didn't notice until i stopped and noticed the coolant in the overflow bottle bubbling, second time i kept an eye on temp's, after about ten minute of driving it creeps up to around 110, keeping in mind this is never getting above 120 kay's or so on a tight road, mostly 3ed gear between corners.

currently the cooling system is stock, stock radiator, stock clutched cooling fan and the oil cooler isn't yet installed.

Decent radiator, a good flush of the system and a good bleed.

Will make the world of difference, keep the stock cooling fan as well.

worth installing the oil cooler as well< i'm a little hesitant as i'm worried about damaging it and loosing the oil, living in the country running over stick's/chunks of tar ect is a real possibility.

for the rad, any specific size/brand i should be looking at? i'm thinking a 52mm twin core should be good for what i'm wanting to do.

You can't track 320kw without an oil cooler, especially in australian weather, well you can but it will only take afew laps at that power to get the oil to 110C+. As for protecting the oil cooler, you could use a duct in the bumper and use intercooler mesh in front of the core.. or alternatively mount it between the intercooler and radiator.. but obviously this isn't the most ideal place with the hot air coming off the intercooler, and in turn the hot air coming off the oil cooler and finishing on the radiator, but people still mount it there.
