Since i've been getting a raise in temperature when holding topspeed, (maybe it's due to hi comp, but..) i opted to try to upgrade my radiator. the old one is still working fine, but I just wonder what would've happen if I change it to a thicker one.
1. fully aluminium
2. aluminium (only the rad)
after for a few consideration, i opted for copper. got it for quite a reasonable price, pretty much almost the same price with choice no 2. although aluminium rads seems like an interesting and tempting device, maintenance reliability comes into consideration. so, copper it is. also with a new cap!
improved better on hi revs. but with aircond on, it's still overheat! now, what next?
