Installing a remote oil cooler on my 63 vert, wondering if I should go with a 6an or 8an braided hose ???

I would go with at least 8an. (equivalent to 1/2" tube) 10an wouldn't be unreasonable. (eq 5/8" tube)
For a cooler, you want more volume than velocity. More volume of oil in a Corvair engine is probably a good thing as well!

I used -8an. I made an adapter that goes in place of the factory oil cooler, and the ports leading up to that are maybe 3/8" so I figured the larger hose wouldn't add any more restriction.
Now, my remote cooler is still in the engine bay, if I were going forward to a front mount I would have gone larger.

-8 AN should be considered the minimum size. most racers run -10 or the ID equal in hard lines.

I use -8 on my racecar.

Adapter was made by Schrum.

The cooler in my race car is built with -8 fittings. They came that way (SOLDERED) from the factory. It has an electric fan on it. I cut out the bottom of the battery tray and mounted it on top of that structure. A fabricated duct creates a suction that pulls air downward. The fan blows the same way. Mine is connected to an Accusump so there is a bit of hard line to that.

Ive never run anything smaller than -10, The thought being less restrictive but as others say -8 works too smiling smiley Mike

8 would be ok for cooler mounted in back, not 6. You will get some pressure drop using anything less than 10 and pumping all the way to the front of the car and back.

Again, thanks for all input I will go with 8an as I’m mounting the cooler in back. Great photos

Nelson, check the fittings you buy... many now are restrictive! and must be drill out to flow correctly.
