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. :(
