[DeTomaso] Front Oil Cooler

Tue Apr 10 17:07:38 EDT 2007

Well I didn't think it was very feasible to put an oil cooler in the front. I just had access to some high pressure hydraulic hose, cooler, etc. (Caterpillar stuff rated at 3000psi). and thought I could/should use it. For my desert driving it doesn't seem like it's necessary.

  Hey - How did I get drawn into this?  I'm not certain what it was perceived 
  I was advocating.

  Technically, the Dawg is correct that I have not run in a speed class that 
  has averaged 125MPH.  However, I did pass him on a two laner in excess of 
  140MPH. The Dawg is also correct that an oil heat exchanger isn't necessary 
  at those speeds.  Actually, my oil while driving on the street is generally 
  too cool and I took measures to make my cooling system run warmer to 
  accommodate it.  Thus, most of us don't need a heat exchanger.

  My experience with the oil heat exchanger was extraordinary on the race 
  track; where it kept previously 300+ degree temps below 240.

  I've heard the Dawg previously say that the brand of exchanger he previously 
  used was unable to contain his oil temps at sustained high RPM levels in an 
  ORR.  Unfortunately, he doesn't clarify that his previous cooling system 
  (radiator et al) was unable to dissipate enough heat energy from the coolant 
  and the car ran hot.  The exchanger is very inefficient transferring heat 
  energy to the coolant when the coolant is close to boiling temps.  Obviously 
  the greater the delta between the coolant temps and the oil, the more 
  efficiently the exchanger will work.  MD, with his new cooling system that 
  can maintain lower coolant temps, may now find that a heat exchanger will 
  yield a superior experience for him this time around. Many elements are 
  interrelated which often why different conclusions on the effectiveness of a 
  part may be experienced by different individuals.
