Well I got my FC cooler and it seams like its going to work quite well. I even found some small fans that should fit on it well, means I dont need to shroud it to the radiator.

anyways, since the cooler is up high, all the oil will drain back into the pan?

is this a problem?

it would seam like it would make oil changes better because you would get more of the oil out at each change.

Which brings me to my main question. How much oil should be in the pan when the engine is off? like 6 or 7 quarts.

Could I just run it, and then measure the oil and top it off while its running?

 

Would still need fresh air. Blowing hot air over a hot oil cooler effectivness not much....ummm...yeah...

Gravety tends to work that way.

Only problem I can see is a false reading on your dip-stick. That amount of oil that usually stays in the cooler will flow back down into the pan...which would make you think you have more oil than you do...or not put enough in when you change it.

Might be a problem on startups and during low pressure situations (idle). On a piston engine if you over fill the oil then oil tends to get beat and sloshed and around by the crank shaft...which causes it to froth up...which sends very sirated oil through your system. This would be bad for a number of obvious reasons, but it may be different with a rotory.

All of your old oil doesn't just flow back into the pan on the stock setup but the system is all levelled with it's self. With the stock system all the oil comes out anyway when you pull the plug.

Considering the oil capacity for the cars I would assume 5qts.

Not and get an accurate reading.

My best advice to you would be to mount the cooler no higher than what the stock cooler was, and run the lins no lower than the stock lines were. This does give you a little margin to move stuff around.

And just to follow sterling's rules....you're an *******.

 

I believe that the cooler can hold more than a quart of oil and it would not drain back. Cold starts might be a problem but the rotors hold oil so at least there is some and the oil lines would actually be shorter with this setup, vs the S5 TII.

And you can overfill a rotory, when I went to a track day, I overfilled mine by a quart, no problem.

theres nothing moving in oil pan area. other than maybe the oil pump chain drive.


as for the temp of the cooler, with two fans and a direct vent from the hood I think it will work. I cant find another place to put it.

 

plan to mount it right where the radiator hose is.

 

It'll add about a quart. Also, what gravity? Its under pressure thru the cooler. Although you might have air pockets with the way you want to do it, I dunno. Maybe not.

 

Is there no room down low and in front of the radiator?

 

I dont want to put it up there.

I already have the intercooler right in front of the radiator, there is also a fuel cooler and fog lights attached to the front crossmember.

 

a fuel cooler?

 

how would mounting the cooler flush with the hood(because its a hell of alot easier) compare with mounting it at an angle.

FYI: I will have two 7in fans on it.
