Hey guys,

i want to buy a new Radiator for my car, and wanted to order a wideband and a radiator from rx7store.net, but they carry only the Standard KOYO, not the N-Flow unit..

The standard KOYO is meant to be 30% better in cooling than the stock radiator.. but how much better is the N-Flow or "tripple-pass" compared to the Standard one?

ill run my car on the Autobahn and several times on the racetrack like Hockenheim or nurburgring in germany, its supposed to do 300rwhp, would i be fine with the STANDARD, or should i get the N-Flow?

thank you in advance

I doubt if anyone knows for sure whether or not the U flow (it's a double pass, therefore a U not an N) is any better than the normal one. I ordered a U flow because I figured that with the inlet and outlet on the same side there's going to be a lot more a preferential flow path through that one side of the radiator on a normal one, whereas the U flow will have better flow distrobution for better cooling. That's just my theory though.

Racing Beat has a pretty good price on the U flow.

oh, so the u-flow (racingbeat says U and N-flow, idk why) isnt a plug n play radiator? as like you said, that the inlet and outlet are on the same side?

It should be plug and play, the normal rad has both inlet and outlet on the same side, which is why it has to be a U flow across rather than an N up and down, which would put one connection on the other side, and it wouldn't work then. Mazdatrix has pictures of the actual unit on their site.
