Stealth, which radiator did you go with?

 

There's 2 schools of thoughts on aftermarket engine cooling..

The first one is obviously to go for a bigger all aluminum radiator.

This is usually the best way to go.. however, bigger capacity cooling systems add weight by the components, and also by the added coolant capacity... In the end you may sometimes end up having more cooling power but a heavier car...

The other way to go , is to use the available properties of your cooling system such as the existing radiator heat dissipation capabilities , but tweak the cooling process itself..

You can always add some water wetter agent that adds better fluid properties to the coolant, like Redline's water wetter, or some other chemicals / additives like DEI's Radiator Relief that have much better heat transfer capacities than water/coolant by itself. They're not cheap, DEI's product especially, but still much cheaper than new hardware and sometimes enough to get the results you want.

There's also the high pressure cap. Higher pressure translates into a higher boiling point so the coolant keep its best properties through a wider temperature range...


Either way, it's all about what you aim to get and what you have already to work with!

 

I've overheated my ENGINE OIL before at a road track session. The coolant temp was happily at the normal mark. And worth noting is I live in the tropics where temperature hover around 95-100F all year round.

I highly doubt a regular WRX driven on public roads (no matter how hard) will overheat <- IMHO.

 

i overheated my car last night in the snow.
i took it to the dealer to get it checked out just to be safe.
if your wondering what happened, my friends made a big boulder of snow and i hit it with my car. afterwards we went to go do some donuts and drifts in a parking lot. my turbo was glowing red hot and steam came out from everywhere. i posted on the other site to see if anyone would know what happened to my car.
do u guys know? if ya do let me know. i hope nothin bad happened to my car. I know 1 thing for sure...i won`t be doing that for a while.
