Who's making these for you? I work for a company that makes OEM rads, and I'm always wary of some of the so-called upgrade alloy rads. Cheap ones are nowt special as far as performance goes. They may look good but some don't have proper airways (no slits in the fins. These louvres direct air in such a way as to increase heat exchange). Some I've seen also have fins which are not properly brazed to the tubes, poor or non existant bonding will result in shite performance as heat exchange can't take place across the air gap. The main factors to consider are: -
- fin pitch (how many fins per unit length, generally more fins = better perfomance but is gets to a point where the restriction to the air flow is too great and performance will drop off). Generally, rads will have a fin pitch of around 1.3/1.4mm.
- tube size (bigger tubes have lower internal pressure loss but are less thermally efficient). Also, bigger tubes = less surface area for heat exchange (because you can't fit as many into the core for a given size). Some tubes are also dimpled, this increases turbulence of the coolant for better heat exchange.
Small rad manufacturers (such as those who re-core rads for the public) tend to use 'off the shelf' tubes and airways made my other companies and they may not be ideally suited to the application they are advertised for. With an average car they'll probably be fine, but worst case is not enough cooling for a high performance engine. I'm not saying all these rads/companies are no good, some will no doubt be excellent, but I wouldn't want people spending money on a rad which may not be up to the job.

have you tried putting this on clubpolo?
might help with boosting the numbers?
Title: Re: alloy radiator (again)
Post by: hayesey on January 19, 2010, 05:16:03 pm
you want to try asking on some Locost/kit car forums as they love polo rads and are prob more likely to want fancy shiney things than most club polo members ;)
Title: Re: alloy radiator (again)
Post by: hayesey on January 19, 2010, 05:16:52 pm
in fact i think the only reason companies make alloy polo rads is for the kit car demand.
Title: Re: alloy radiator (again)
Post by: lance on January 19, 2010, 06:09:30 pm
not the shiny factor im after its the cooling factor. alot of kit cars do use the polo rad though. caterhams mainly.

havent really tried anywhere yet mate other than on here.

(http://www.radtec.co.uk/picts/pro_b_1_330.jpg)

Westfield Universal radiator. Fitment as original. A lot of Kit cars were fitted with the VW Polo radiator, plastic tank alloy poor performance core. Radtec have made an all aluminium vastly uprated version of this radiator
that can be fitted as a direct replacement to original.

Optional extras:
1)Powder coated - £35
