CSF Radiator + Condenser, Upgrade

Valentino · 06-17-2010, 01:11 PM

I got mine over the middle once. On a race track air temp was 95F.

'10Anamoly · 06-17-2010, 01:18 PM

The product looks great but the only cooling I need is oil cooling. My temps are below the middle almost all the time too.

Still waiting to hear if that gap is a prototype-only issue or not.

And can someone explain to me what the heck B-tube technology is.

That's because the Water Temp LED readout is not a "real" gauge. The same 7th light stays lit from 156 degrees to over 215. Watching a Scangauge output, the Z runs pretty cool for a modern emissions equipped car. Typically around 180-185. Water temp is really not an issue, except perhaps under heavy and hot track conditions.

Sorry Phelan, forgot to post up. The gaps are part of the design, but they're going to try to line up the fins better.

Also regarding cooling, this radiator is not only supposed keep water temps cooler, but in turn help with the engine oil temperature as a result of the coolant that flows through the engine being cooler. The 370z heavily relies on the radiator to keep the entire engine cool. By installing a more efficient radiator, your entire engine will benefit from the increased efficiency; essentially knocking out 2 birds with one stone.

Mike I would be willing to test their radiator! 4.5L Sleeved block can get hot! What ya say... would they be game?

Vegitto-kun · 06-18-2010, 05:37 AM

I think that I wouldn't want this.

future oil cooler + this would be cooling overkill

bullitt5897 · 06-18-2010, 10:47 AM

Thanks for all the PM's Mike!!!! I look forward to running their production version in august. Now I have to find a good local shop to do the install... hmmm maybe z1

The way I look at it is; hit the core of the problem. Why add more parts to your car when the problem can be fixed by upgrading an existing? On top of that, it improves the cooling of the entire engine instead of just the oil.

Replacing the radiator seems to make the most sense to me. Let me know if you feel otherwise.

Well...Ultimately the Thermostat will regulate the engine water temp. A larger more efficient radiator will just cause the thermostat to close down to maintain its setting of roughly 180 degrees. In normal day to day driving I would expect no difference...

That said, under racing conditions where the Radiator may near it's upper limit of cooling, an uprated radiator will help by raising the (water) cooling overhead though no one has mentioned this as an issue to date

So when all is said and done, there is a market for this part albeit a small one. Track cars and FI turbo'd cars being the target I would guess.

Oil cooling is a whole separate issue and should be addressed with it's own cooler. Oil temps reported here seem to vary more by usage, then by engine water or ambient air temps

Well the biggest problem that the 370 has is the oil temperature, not the water. I know that better water cooling might help the oil abit. but honestly it wont so much a difference. I drove at spa francorchamps for a whole day and the water temperature if I remember was only one dot above the normal one. Oil was extremely hot.

Our current radiator seems to do its just quite well.

Well ofcourse if you send me one to test it out I wouldn't mind at aaaall

What would be considered a high water temperature?

My HR G got up to 220F (Uprev Cipher) after about 10 consecutive dyno runs. The fan on the dyno was blowing hot air due to the 120F ambient temps.

That's not very high actually. The radiator fan cycles on at 215 degrees. You can see that sitting in traffic on a hot day..

Q8y_drifter · 06-21-2010, 02:20 PM

the fan is set at 215F? hmm...
I think mine is set lower due to GCC cooling specs (we have bigger radiators, lower temp thermostat, standard trans oil cooler, sandwich plate oil cooler/warmer, etc.)

What is the actual temperature of the water when it's half way on the car's gauge then?
Cuz our gauges here are different. Temps for me reach about 195-200F during normal driving and the gauge is at about 1/4 only. All nissans here read this way.

In the US the gauge is bogus. The same 7th light is lit from 155 to 215+
