You forgot to mention the thermastat (100) so that makes it 100 for the ducts.
I was thinking of making my own but suddenly the CRW kit doesn't look that expensive.
so.... ~10 fittings ($200), 2 19 rows and thermo ($340), say this is just a wild guess 30ft of hose ($170) = $710 ....yeah id pay $200 for the ducts so $900 is an ok deal from CWR

That's great news. How about on the track? What kind of temp do you see? I checked out your website and it said with the R1 dual oil coolers, you saw 240+F right? I wonder how much improvement there is. Thanks.

Emperical data from my car. I use the ducted CWR 19 row coolers with a OE front end. On the *street* my oil temps sit pretty much dead on the tstat opening temperature - ALWAYS. There is no question the 25 row coolers are effective. Is it better or cost effective upgrade for the street to go even bigger? IMO questionable as the tstat is already governing the temp it is obvious the coolers are already "oversized." Will 25 or 30+ row cooolers be better for the track? Possibly yes. But ONLY if ducted to force the air through the cooler. No matter how close to the nose they are located if you have ANY gaps you're loosing airflow through the cooler reducing it's effectiveness. The ducts are the key. No ducts and the bigger coolers aren't really worth it. .....IMO of course
I do however sympathize with the issue of providing ducts for all the aftermarket noses.
Rotormotor,
You did the same math I did. When you consider the assembly of the hoses and fabricationof the ducts, to me the $200 "premium" for the CWR kit was worth every penny. Plus I got to put more *functional* CF on my car

Crispy

No problem. My wording isn't clear on the website. Not your fault.
For the 34 row, an aftermarket front bumper will be recommended because the core extends further down. You can't really take the full advantage of it without a bigger opening. This thing is really for track racing. You will never need dual 34 row on the street unless your motor makes a lot of HP.
Tom's car has the dual 25 row, not the dual 34 row.

"To take full advantage of the monster size oil cooler, an aftermarket bumper with larger openings for the oil cooler duct will be highly recommended. The best bumper that works with this oil cooler setup will be the Mazdaspeed GTC bumper."
I have seen the monster oil cooler setup on Tim's car. They are HUGE!

All I am saying is that no one likes it when an idea is waved in front of there face and then not given to them.
A good working do-it-yourself oil cooling system would help a lot of fellow rx owners. It is too late for me becasue I already have one installed.
Both Chuck and Dwane have very nice systems. I have purchased items from both of them and they have been great to deal with and either one can provide you with a suitable ready to install oil cooler system.
I will PM you clayne.

Just for comparison's sake, I checked w/ Mazda Comp on the cost of the OEM parts to convert the single oil cooler in my base 93 FD to a dual oil cooler (R1-style, or per the parts catalogue - "hard suspension"). I'm in the Mazda Team Support program, so this is best price you can get on new OEM parts. The passenger-side duct and cooler plus the oil lines, and brackets added up to more than $800.

That makes we wonder what I should be asking for mine, since I now have an R2 cooling system with only 26K miles on it lying around on it.
If anyone is serious about doing it alone, take a good look at CrispyRX7s page. It contains a nice large photo of the entire kit. You can see the parts needed.
FYI, rough pricing of the coolers and thermostat is 350 alone.

Chuck,
In answer to your question of last November:
I see track oil temps that track water temps. This is typically in the 210-220deg F range on days with ambient temps in the 90's. Note this is with a car with stock front nose and all accessories (PS, A/C etc), and running the heat generating stock turbos.
FWIW,
Crispy

Even though the install of my CWR duels was a PITA, I am glad that I did it. This was probably one of he best upgrades that I have done yet. Especially since I live in Hot-as-Hell-Houston.
