dont think you'll get cheaper than this. maybe put it on club polo too.

[poloeatonm45]

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.

I am not interested in buying one (skint as) but would also like to see the stats requested above.

Also - are you finding your car running hot?

dono pal, my car still isnt running 

[poloeatonm45]

is their anymore info on these then?

really interested but dont wanna waste money on a rad that is gonna be no better than the one i have atm

steven

it will be a standard size rad in full alloy with a 34mm core

[poloeatonm45]

oh sod it i,ll have one it cant be any worse than the one i have now lol

the ones i was gonna get where going to be shipped to a port and id have to collect and sort customs out. i have been in touch with an english company now that make them he emailed me this,

Hi sorry for delay only we have just come back from doing the autosport show at nec,as for prices 5 off @ £195+vat ea 10 off @ £172+vat ea and 20 + off @ £161+vat ea.Hope this is of some help Regards Darren

but i dont think we'll get 20 people interested.

have you tried putting this on clubpolo?
might help with boosting the numbers?

[hayesey]

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
