hello boys and girls
i have a few questions, im tring to build a vmount in my fc and at this point im researching. and right now im stomped on the radiator im curious as to what kind i should get.
cross flow
down flow
dual core
3 row
so many options i would appreciate it if those of you who have built your own kits have any ideas or suggestions as to what kind of radiator i should go for. and if it a necessary that i convert to a electronic water pump.

 

im using an afco dual pass on my vmount. they are cheap as hell and have many size options.

 

I used a 19" tall by 26" wide by 3" thick 2 row Griffin cross flow single pass.

I think a thicker 3 row would be great if you are predominantly doing higher speed track events and seal very well around it or if you are doing low speed stuff and use one hell of a powerful puller fan(s).

My setup was overkill till I got some real traction on my set up- then I was glad for it.

I would NOT use the typical dual pass on a rotary, our water pumps break the spot welds in the divider plates and block radiator flow.

If a dual pass had a split end tank with the divider welded in across the seam I would be comfortable with it- otherwise, to me it seems like just one more thing to fail.
