[DeTomaso] Oil Cooler - BS

  Let me know where you slackers live so I can drop some napalm on your positions. ;-]>

  How many times have we discussed this issue?  Okay ...one last time:

  1.   Unless the Laminova cooler is allot bigger then what Erik and I put on my Pantera it won't work on a built engine for more then a few minutes (in my case about 5 MINUTES) at WOT (5500-7000 rpm) or at keeping oil temp under 280-300+F. I gotta look at what Jason "the kid" Eaton put on his Pantera but he's talking about taking his street modified Pantera AND averaging 150 mph or more IN May and beating  Grampa Dawg down at  the NORC...Okay yea, Crazy Dan tried to do that too at Silver State too and we aaaaaaaaall know what happeed to Dan with that big bad chevy Chevy motor! ;-)  
  Don't beat me up Dan!

  2.   "UNLESS" you have also upgraded your cooling system, added taller gears and added a larger capacity rad designed and built for racing in mind don't try to keepo up with me for very long. What I am talking about here is pushing the envelope on your engine and cooling system at endurance speeds.  Not running 100-125 mph in ORR (Chris & 99% of you) or running on and off the throttle in track events for 20-25 minutes....but running 145 to 175 mph above 5,000 R's for 30 to 45 minutes or longer.

  3.   Start running at 6000 and up for more then a few (5 minutes in my case) the oil temp used to to 280F in like 5 minutes or less without a oil cooler or the old Fl;uidyne air-to-oil cooler and stock gears.

  2.  Agree with much of Mike's comments however I can definately say that my water temp DID GO UP 20 degrees even though the heat exchanger reduced the oil operating temp by the same amount....back to the drawing board we went. and added taller gears and replaced the Hall "Phoenix brass rad.

  3.  The standard Fluyidyne aftermarket rad that most of the vendors sell did a worse job of cooling then my old Hall brass "Phoenix"....I know some of Gary Hall's inovations were more form then function but that damn Phoenix radiator worked great in ORR....just the quality control on ALL 4 that I had all eventually starting leaking after a few months. Don't know what that was about....only one that never leaked (#4) burned up in a little fire....I will say Gary always exchanged a new with a old 

  4.  With a large Fluidyne air-to-oil cooler, the taller gears and a heat exchanger averaging 150-160 MPH with 200F OIL & WATER is a breeze. 

  Don't think adding just  taller gears and a small inline luminova cooler will be enough to keep operating temps down on a built 400-500HP engine unless your running RPMS are under 5,500 R's

  For the last 2 years my ORR/sustained operating temps  at 150-175 areaveraging
  200-210F OIL TEMP
  190-200F WATER

  Now shut up.

The factory Gr4 cars did have a very wide, short air-to-oil cooler mounted 
below and in front of the radiator; I don't know how well that worked.

temperatures aren't linear--that is, you don't add 20 degrees to the engine coolant 
when you shed 20 degrees from the oil. I've read here that it's about a 10-to-1 
ratio, i.e. dropping 20 degrees of oil temp only adds 2 degrees of water 
temp.

We'll see?
