Koyo N-Flow Advan & DisAdvantages
 

What are the advantages and disadvantages of having a triple pass radiator. Is it really worth it to get a triple pass.

well it all depends on you really. are you going to track it? if so, what other cooling mods do you have planned? if its just a daily with occasional spirited driving, its not needed. just my .02

What about the complaints I've heard on other forums on pressure loss due to the 3 passes and requireing a high-flow water pump to increase the amount of flow thats required for a 3 pass.

If you aren't building a road race car, it's not worth the effort. Just get an aluminum replacement radiator and be happy.

If you are building a road racing car, better cooling is always a plus.

That was pretty much the consensus in the Mustang & Camaro Forums. Just wanted to make sure.

If the price didnt matter would it be better to get the N-flow. No one here has said anything bad about it or any disadvantages.

I just installed the Koyo N pass, my Evans coolant temps at Lime Rock Park on 5/6/06, ambient 66F, was 185F all day... worked great...

But how are the temps in everyday driving. (ie. traffic & stop/go)

get an aluminum replacement and do the Dale Clark FC fan switch mod.

I've done that, but I have a chance to get an N-flow for the same price as a Standard Koyo.

Around town 181F ...no brainer... buy the N-flow... you can never keep a RX7 to cool...

You see thats the weird thing. I've been reading about triple pass radiators on other forums and all say dont get them. That they are specifically for track use not street use. They list all these things about coolant flow turbulance and how much more pressure is required to flow the same amount as a single pass. Hopefully those others who have N-flow will also chime in on their results/opinions.

So what are they saying happens when used on the street? My bottom line are the coolant temps read off my PFC... .so if the car stays cool on both the street and the track its a winner to me...
