RX7 oil coolers, do they work? Options

[DanT]

Any one used one on their car and does it work efficiently...especially for a track car? (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif)

I'll give my 2cw.


I've had a Mazda unit installed in my 6'r now for a couple years.

Since I do all the work on my car myself,I took the liberty to cut the end off the cooler and make up a bolt together flange setup .I already had to cut the endcap to install -16 weld bungs,so why not make the cap removable to facilitate cleaning.
I also that inside all Mazda coolers,there are baffle strips inserted in each cooling tube to slow the oil flow thru the cooler.
I guess these are the slow the oil to allow the heat transfer.They can be removed,and it'll increase oil flow,however I didn't remove any so I have no idea what outcome would be without these restrictors.

In addition,I added a Canton oil filter on the outlet side for safety.It's rated @ 8microns I think.

Even though my car is not yet licensed for the road,ya I know,it doesn't have a load on it,here in SC,on a 100 degree July day,I'd let it idle for 45 mins. at a time.The temp never got over 210 with the colloing fans running.

I think it'll be alright,but we'll see.
