CSF Triple Pass Radiator
 

CSF has improved their radiator from single to triple pass. Apparently there are only 5 in the US. One just arrived at my house today:tup: Big thank you to Tony at Fast intentions!

Ill submit my review once I install it in a few weeks. Still waiting for a Fast Intentions Oil cooler:tup:

Someone also has a full review and info on it...its apparently way better than the original:happydance:

Link is being censored on the forum so I added a space in there...

Interesting, would love to have seen some data logs with the original CSF v the new one. He mentioned it cooled down faster but was it able to hold temps lower overall even on tough hotter part of the day. He mentioned never going over 222F which is good but need some data for comparison.

Also, he was doing 5 hot laps then a cool down because of oil temps, would like to see more hot laps to see what happens (ie get better oil cooling to really push radiator to actual limit).

I did log the original CSF radiator temps and compared it to the triple. I wrote all that data in the article.
Also, I have a Nismo 34 row oil cooler which is equivalent to what most track and FI people run
You paraphrased a lot of what I said in the article.

Awesome testing. Looks like this could be my new radiator!

I saw that, but one I was referring to is actual data logs, like excel list or graphs showing the increase over time.
Knowing the car topped out at 2xx is great, but in what amount of time be a huge variable to compare OEM v CSF v 3 pass CSF. Also was it a quick jump up to 2xx and then a constant temp throughout the entire track session or was it a gradual increase. Additionally, what are your fan speed settings at OEM/CSF/3 pass CSF which can alter the cooling temps.

A lot of variables to consider which are not mentioned in your article.

It looks in the pictures like the Seibon TS hood is being run without aftermarket hoodpins (though I could be wrong). If so, that's good news since hoodpins has always been one of my main hangups with going with an aftermarket CF hood.

The reason I am being picky is because of many who have the single pass CSF radiator, and the need for "real" numbers and results to prove it is an overall better design & radiator.
Have plenty of results of OEM v CSF (or Mishi) radiator, but this is new so considering all variables to ensure a fair comparison and not just some marketing fluff that it works better.

I know most if not all Seibon hoods can use the OEM 3 latches which gives it a very strong support & seal when driving. I have been in the low triple digits of speed with mine with no issues, but only had my seibon TS hood about 4 months now.

Are you happy with the fitment and the finish? Did you go dry or wet carbon?

Seibon TS is only wet, so a few pounds heavier than stock (though really do not notice).
I really like it, I would say my passenger side has a slightly, very minimal, gap between the fender & hood. I mean the OEM hood to fender there is some room but there is a little more now on just that side. Latches down the same, is very sturdy, I painted mine completely so no worry about the CF fading or anything.

I've had my Carbon Creation hood up around 140 with the stock latches and no problems but it was flexing a lot. Part of me wants pins for safety but I just hate the look.

you're right, i dont have excel spread sheets for it, I tried to give a idea of how the heat increase behaved through out the session, but i see you want more detail.

i can assure you it was a gradual increase with the triple pass, the single pass liked to jump up quickly and over all couldnt keep the car as cool in less time.

Fan speeds are OEM since the beginning.

yes i have no hood pins, but the Seibon uses the 3 latches like thedreamer mentioned

My testing isnt marketing fluff, im another 370 owner and track guy like alot of others here. Ive been working with CSF in testing and developing this radiator and i wouldn't have signed off on it working correctly if it wasnt right. Im more then happy to try and answer your in depth questions as best I can, but just want to be clear that im not blowing smoke about this product, it really works well.

same experence ive had tracking mine ^

How much does CSF plan to sell this for? I'm a huge believer in a cool running car. I absolutely loved the last setup in my old Z with the GTM 70mm radiator, but having to buy a new shroud, cutting everything up to fit and the sheer cost has me thinking this is a better route. My oil temps have been retarded on my stock 13' Z here in PHX. It needs some serious help.

Time to change your signature pic to the phoenix!

msrp $650

Just on the basic physics of the thing, it should always be a win. Good to know, I guess this will be my next radiator whenever whatever happens to the current one :)

Is there any special pricing or discount for those who have CSF single pass?

Edit: Are they in stock?

Can't do it... Welllll, can't do it if you still want to run to the OEM in radiator trans cooler.

Ravi @ CSF sent me an email stating:
The triple pass design is only for manual transmissions as you can not have both an oil cooler in the tank and separators for the passes together.
However, we have bumped up the efficiency of the automatic version about 20% as well using a smaller fin height (6.5 instead of 8mm) to pack in more tubes and create more surface area contact between the fins and tubes as well.

Couldn't you in theory run a separate trans cooler?

Well yeah, I already do run a separate air-cooled Setrab unit for the trans, but it's only enough because I'm also getting the water-cooling via the radiator. Having the trans fluid and the oil both interacting with the water system directly for cooling is nice, even though they both have separate air coolers as well. Water helps warmup and stability. Maybe if I had a dual-core Laminova (running oil + trans fluid on the lower rad hose), then I'd think about switching to a radiator with no trans cooler in it.

Yes you could run the manual version and a separate trans cooler if you had an automatic transmission.

The units are trickling into stock into both our West coast and East Coast warehouse.

We have about 10 units coming in this month (most sold already), and about 50 next month.

Unfortunately, we don't sell directly to the end user so we can't offer a discount to previous owners, that would be up to the retailer.

Right now Z1 motorsports is buying up the stock we have for fast delivery and Stillen is also taking special orders.

Please let me know if you guys have any questions about our new unit. We are very excited about this unit, and we look forward to hearing all the feedback from the lucky guys who were able to get their hand on these early!

Thanks for stopping by, CSF! I already have one of the new units waiting for me. :happydance: Can't wait to test it with my TT setup.

^looking forward to seeing your results with the turbo power

Z1 Motorsports has 5 units of the manual. That's all we have in the country at this time.
Also a few automatics as well.

Keep cool

does it use the same drain and pleed plugs as the old unit?

Can you fit a condenser unit in front of the rad for A/C ?

After receiving several complaints about the integrity of our drain plug and bleeder screw, we have addressed this by using much stronger aluminum for these components.


Z Eliminator - the cooling system module comes with the condenser, and is a complete drop in fit to replace the entire stock cooling system.

Please see picture attached.

Yeah, they make 2 models, 1 with and 1 without

Kinda pissed they release this only a couple months after I bought and installed the original

Could always ask for a buy back for the purchase of a new one potentially?
I just bought a second one, after the first failed, about 2 months ago. :(

If it wasn't such a pain to replace the damn thing maybe

I know that feeling, but that's kinda part of the mod game... I have the old one, and I bought Z1's old 1 piece rear rotors knowing that they would have 2 piece rears. Shít happens

Got it finished about an hour ago! Only thing I recommend would be to use the green rubber oring from CSF. Dont use the OEM black rubber ring on the condenser reservoir. :tup: And I did not have to use the supplied ac lines. OEM ones worked with very gentle bending:tiphat:

is 102* F outside...Plugged in my scangauge and immedietely saw it working better than stock. Anytime you get moving from a stoplight or coast down a hill the water temps drop very quickly where OEM would never drop at all. Im pretty happy with it! Ill give a full review in about a week:tup:

what failed on it?

I doubt it. Even thought a had 2 radiators leak from the same location (upper hose neck), they refused to replace it and blaming my motor mounts. I now have solid motor mounts and a recently purchased and installed a single pass version. It would have been nice to know that they were releasing the triple pass, as I would have opted to wait for it and have it installed (especially since I was buying it and not having it replaced by the manufacturer). I will be looking into getting one, but I am not in it a hurry at the moment. I really want to see how long the single pass I just purchased is going to last (and if it will leak from the same location like I expect). Who knows......I may just call UPREV and get it anyway.

I got the new csf radiator from Stillen on Tuesday for 600$ but I waited for it for 9 weeks. Haven't had time to install yet but it looks amazing polished

The lowest 4 fins or rows on the passenger side started leaking, like the welds each slowly came apart. Basically you could load it up with fluid by the end of the day there was none left in the system.

I spent a hot weekend at Sebring and I guess this is the next thing the car needs. I had to keep backing off to let the car cool down. Is it much larger that the OEM one? I'm curious if I'm going to need to move other coolers to make room for it.

It is a bit larger, it fits in the OEM spot and does not interfere with anything really. I believe it is larger towards the engine so does not push out towards the bumper.

Perfect, thank you!
