I decided to mount my large NPR in front (in the nose) of the car so I can go back to a stock mount upgraded radiator , question is after reading about the various ones you guys use I am still unsure about which to get , which would be able to effectively cool say ....... 500rwhp worth of heat ? , remember its a street car , 1/2 BP , T66@18-25 psi , H2O inj. etc , etc , thanks again guys.

 

i would say try evans for sure.. see how that does to your temps

 

I have the factory radiator, clutch fan and shroud and have never had any overheating problems

 

With which one of the after market ones ? . , I like the KOYO because of the size but I am a bit concerned about cooling air flow.

 

Can some one please answer ? ..... ,Koyo or Fluidyne?.

 

Not sure on an FD but on my FC the fluidyne helped out alot. Very high quality piece. I would expect the same from the FD one.

 

Thats what I have been reading but , not wanting to be an *** , but I would really like an answer from someone with a high horse power car , I expect to be making a bit of power when I am done and would like to buy the right radiator and not have any problems . Any one with a high HP car using either of these radiators ?.

 

fluidyne looks like it is built the best but use a high cfm electric fan

 

Have you ever seen tha Koyo? If that thing isn't overbuilt I don't know what is!!! I admit I have never seen a Fluidyne in person but I couldn't imagine anything being built better than my Koyo.

 

I intend to use the stock fans which I have wired to be turned on simultaneously by the E6K when it sees 190deg. .

 

Ok FINE !!!! , since nobody wants to answer me I will go with the FLUIDYNE , since I haven't read one complaint about that one , I don't think the extra half inch more on the KOYO would be worth the risk ......... later.
