I currently run a single pass KOYO rad with a large Isuzu IC , my oil and water temps are great , especially on the highway , however they tend to rise a bit (95-98 deg C) when I'm in trafic for a while or when I stomp on it in short back to back bursts . I am soon going to be installing a Miezere 55gpm electric water pump (and maybe a thicker 4" intercooler) to keep temps under control , I'm also thinking about putting in two baffles (one in each tank) to convert my rad to a tripple pass , has anyone done anything like this ? , is it possible to do this without damaging the rad ?, anyone have any results to share ?

 

I just purchased a triple pass custom radiator instead of possibly butchering my Koyo. After I sold the Koyo and paid for my new hugh triple pass radiator I still had some money left over!

However I do believe it would be possible to modify your existing radiator. I decided not to chance it.
Koyo also maker a triple pass radiator called the N-Flow.

 

Never heard of this being done before, i never had problems with my Koyo. I also appreciate the diagram, because i have no clue how they actually work; until now!

 

I know I will be able to get a custom rad at a cheaper price , but I want a stock mounted rad , my stuff is alteady built around a stock located rad . So how does it perform ? , I will look into the N flow , thanks alot man !

 

I use the stock fans with mine.

 

Been looking around for the N flo but cant find it , U know where I can get some info , part # and maybe a price ?

 

Found it at Absolute radiators.
