Will the Koyo fit fine in the stock V-mount position with my GReddy 3-row stock mount intercooler?

 

There maybe some fitment issues like most Koyos, but it should clear fine. Koyos are nice for the price, but I wish they were not so thick, thats what is nice about the PWR, Mazda Comp, and Fluidyne.



I am actually working on a triple pass radiator for myself, mainly for the the sole reason of running a FMIC. Alot of Japanese tuners use triplae pass radiators w/fmics with no over heating issues.

CSF Aluminum (As large as a Koyo) for $279 shipped.

 

Just bought the "competition" radiator from SRmotorsports. Both it, and their "ultimate" radiator have a larger core than both the Koyo and the Fluidyne. Bigger is always better when it comes to radiators.

 

Bigger is not always better when it comes to radiators.



You need a good balance of internal and external flow. There are many characteristics that effect each core, whether it be the overall thickness, number of tubes, number of passes, fin count and fin design. The most versitale radiator would be a single row core in the 1.250-1.50" range. This is a vast improvemnet over the OE core size, yet you still achieve adaquate airflow through the core to cool the water/coolant. A larger core is best if being used for racing purpose where the radiator is seeing clean air from the noise, due to the added thickness and the slowing of the ambient air thru the core.



You really cannot compare one radiator to another, mainly because thickness, number of tubes, fin count and fin design are different for all, even within the same manufacturer. Each radiator is designed for a different application, and each setup may require a different radiator to be most effiecient.

 

Its an FD, bigger is better.
