Oil Temp What's to hot?
 
I have my water temp at 140 and oil at 230 and gets to 250 when running faster. Is this too hot should I get bigger oil cooler? I am running no water pump just and raw water pump getting 5-7 pounds water pressure. Other suggestions. I am running 540's with no super chargers. Thanks

we rarely see more then 220 during a race conditions spinning 7400prm. I look for 200-220 as acceptable under load, cruising its about 180 or so (dont like to see much less then that)

Can you clarify this?

Which cooler are you using now?

I assume he means he doesn't have an impeller in the drive, just the Block mounted Pump....

At least I hope that is the case...

225 is about as hot as you want to see.

Yes block mounted water impellors pumps and seperate oil coolers.

Which size coolers?

That might be a little too hot. I would recommend a bigger oil cooler. My boat (Fountain) has never gone above 180* at WOT, (500 EFI). What oil are you running?
