Well guess what,, that will increase flow across the radiator. Any radiator. It will even help the stock radiator cooling efficiency.
But for us people that live below the 45th parallel. We like A/C.
That would not be an option for most people if you have to do that to use the Mazdaspeed radiator.

The Ron Davis Rad that Mazmart sells..and the Griffin Rad that BHR sell....are not even close to the rad Ron Davis makes for the race teams....
C&R also make a monster rad for the race teams as well....
The comparison between the Regular Ron Davis Rad and the Motorsports Rad is like comparing a minibike to a GSXR100 Race bikes horespower output

Dump the A/C condenser? You mean take it out?

You don't have to remove it...but it doesn't come with the brackets or the bosses to hold it on to the rad....that's where the fabrication comes in...same with the fan brackets...they need to be custom fabricated as well....wasn't too bad a job...took about an hour with a TIG welder
I am actually thinking about doing a v-mount of sorts for the condenser and see if that works

And this is relevant why
Come on Jeff.......you have to do better than that
How many Motorsports rads have you installed?
Also...it's a moot point in some series...cause they often can't swap out stock parts
Wanna see some pictures from a couple of teams radiator setups I have friends too

....yes...what did you think we were talking about
Usually Mazdaspeed Motorsports custom parts are race use parts.....
I wasn't trying to bash your BHR Rad...it's an awesome rad for stock application..and likely the best thing out there for plug and play.....but there is no way in hell it does the same thing as a full double pass rad.....

If I experience any overheating on the track now that I am supercharged I will be changing to one oil cooler on the drivers side and a second radiator where the passenger side oil cooler would normaly be.
As an added bonus, removing the stock oil cooler lines would probably remove some weight and increase oil pressure/flow.

This is something I've had in the back of my mind for a while now .
Which country seems to have problems with oil pressure/brg wear ? Yep , the US where they use two oil coolers . The JDM 8s all have only one and probably see higher oil pressure than the US models (can't confirm).
So if you wanted to fit an extra water rad. where the 2nd oil cooler would go ,what would be good to use ? How about one that fits perfectly and even comes with all the cowling to direct air flow. Yes , the one that is already there ......

It looks like most of the suggestions here are for FI type vehicles where a lot more heat is generated. I chased cooling, and associated A/C problems here and most turned out to be stock fan, stock wiring, relay and "foam" related. Basically, much of it was working as Mazda intended.
I pulled data from most of the folks that have posted to this thread and solved my problems. I stuck data and links in the thread in my signature. If you are starting out with an overheating problem, try this stuff first. I will have the MM fans on early when the Cobb comes in. Then when I pay that off, I will likely go with the thermostat to finish things off for good.

And their radiators are exactly as I described.

guys lets stay focused. i would prefer to stick with the street driven casual track day n/a or f/i car.
you get into race teams and what they do and it becomes a different world. Plus they do not have to be concerned about low speed, stop and go and a/c. etc.
Much different world.
Thick rads seem to not work as well on the street due to the average lower speeds and cooresponding less airflow. The air passing through a thick rad gets hotter as it pass's through, lessening its efficentcy. Thickness is sometime unavoidable due to the space available.
The second radiator does increase flow latency --for that system. That is why i choose to use the plumbing i did .

Actually all you said was they are Ron Davis and Griffin Rads.....
Not which type.......
Anyway...most people don't need or care about the larger rad that I am talking about
It does belong in the conversation..but I'm not going to labor the point any longer
I still don't get the extra rad and no extra oil cooling argument though...

The oil coolers are in good airflow and only provide 1/3 overall help. oil temps are not critical for the people i see and myself. they range about 10F higher than coolant temps unless something is wrong. if the coolant spikes to 230-240 on the cars i have seen then the oil stays in line with it. As long as the driver backs off some.
address the coolant and the oil temps will follow--
the biggest issue to me in the winter is getting the oil to warm faster.
on the track with sustained 9k running with a race engine---yep they need help.
now if ypu are still running 5w/20 or not changing your oil until 7k miles then yep --i see your point.

going to a single more efficient oil cooler with 10an lines and a proper oil thermostat would improve the oil cooling system.
For someone with fi or extreme climates that tracks their car, what else can they do besides a sec radiator if they still have heating issues after an upgraded radiator (bhr or mazmart) t-stat, water pump, a vented hood and all systems are functioning properly?
A secondary radiator could be installed for about $100 in parts, which would be one of the cheapest cooling mods.

Yes...the oil coolers can be improved..and the thermostat is definitely an area of improvement. I have an Earls Billet one that allows my oil temp to warm up faster..and provides much better cooling than the stock system
I'm on the fence about the single cooler..unless it's a Setrab or similar and big ( just cant seem to pop for the damn thing though (..the cooler I want is close to 1K ) Seems to work better than the stock system though from the guy that uses it
I haven't tried the additional radiator thing because in my mind a bigger..better RAD makes more sense to me.....and was worth the PIA factor getting it in and working
If you spent the cost of the other rads..the other mods...and you likely would end up at the same general price point....so cost isn't really an issue either.
It's like everything else...there is more than one way to do anything..and often the results are the same

yes no crash beam
i work at napa so i was able to track down a stock style therm that opens at 160
