Smile Radiator Qs

I have the original brass radiator that came with the car and wanted to know how much horsepower is it good for before I have to upgrade.
Any help is appreciated

The original radiator was plastic and aluminum, brass is an aftermarket replacement.

The aftermarket copper radiator is nice because it eliminates the stock radiator's plastic end caps which crack and burst now that the plastic is old and brittle.

Its a little heavier than stock and more expensive to make.

Be sure to flush it well and keep fresh coolant in it as corrosion starts on the inside of solder joints that will block flow.

Cooling will depend more on surface area from design rather than material choice though copper does transfer heat better than the stock aluminum.

I would rather have an aftermarket copper one than stock!

Jeez u guys know me like the back of ur ********

Well after much reasearch on the webz.. The general concesus was that brass/copper had much better heat dispersing qualities compared to Ai...so I would assume that it would be better. But ur right silly me for thinking more than enough of you would know this.

Thank you Blue TII

You didn't get the joke. You were getting your ***** busted, Newb style.

Your post sounded as if you expected the Radiator choice to *produce* additional Hp.

Personally, I would choose the aluminum over copper due to the weight. As far as the heat goes, take in consideration the following:

Airflow through the radiator
Coolant mixture
Ambient air
Engine heat
Coolant pressure
Amount of airflow available for the radiator
Fan CFM
Thermostat

Those will affect your cooling system. HP or BHP is not the preferred way to measure your cooling system capacity.
