Radiator Cooling suggestions

JWillis72 · 01-08-2015, 02:24 PM

I looking for ideas for more cooling for my car, I ran Homestead a couple weeks ago and had it hot (light before hot or first light in hot) most of every session and it was only in the 70s. I have a CSF triple pass radiator in it, the hood is vented, running water and Water Wetter and have the fan going to 100% as low as I want to go. Next week we are installing a Stillen bumper, removing the washer fluid tank, venting both fenders to move some of the coolers to the side with fans to try to get them away from the radiator. I thought moving the heat away from the radiator would help but I am also adding a Frozen Boost cooler that will be in the way. What else can I do to cool it down?

Better fans & fan shroud, you just need to pull more through and out faster to help.
Having the vented hood will help this as all that hot air can get pushed out of the engine bay quicker.

Never mind

Do you have a fan/shroud to recommend?

Fans I would go with SPAL, shroud I don't think anyone has one specific for the 370z ever.
I will say this only because I know a member has one, but GTM had a fan/shroud combo built and for sale. This leads me to believe either the SPAL fans fit our shroud or can be modified to do so.

um... not sure but do you also have coolant and running distilled water?

that could be why your not cooling as much as you'd like....

Only other thing not mentioned already that I can think of is switching to the "pressurized" system/reservoir from the 12+? models. Wont help temps but will increase boiling point a bit.

It's distilled water and Water Wetter. From everything I have seen it cools faster than antifreeze and all the tracks around here do not want antifreeze on the track.

An oil cooler to help keep his water temps down?

JWillis72 · 01-08-2015, 04:55 PM

It has one and oddly the CSF radiator helped my oil temps, guessing it allowed more air flow.

Yep. Might not make a big difference but anything you can do to remove heat from the engine will help coolant temp.

At OP: Are you sure the vents in the hood are doing any good? If placed in a high pressure area, they could be counterproductive.

JWillis72 · 01-08-2015, 05:20 PM

I'm 100% sure, it the best cooling I have done. Every drop of water or supercharger oil that comes out gets blasted all over the windshield like it came out of a cannon, they are flowing lots of air.

JWillis72 · 01-08-2015, 05:23 PM

The top vents (closest to the windshield) that are questionably in high pressure areas are covered in plexiglass.
