i was curious bout how good there were so i went and asked a.r.e radiators and coolers.. for those of u who dont know a well respectd radiator and cooler place in brisbane.. they said for the price they r perfect they flow good enough .2psi loss at 15psi... he also said of course ours flow better but they arent as bad as people make them out to be.. a m8 is pushin 200rwkw in his datto its ice cold at night after a hard run.. and 1/3 of the core is also cold top to bottom.. it has to be doin something right,...
