 From your web site, you are getting consistent 0-60 times when you don't
 drop the clutch, but they are slower than 7s.  Your clutch being hot may be
 a factor.
  The engine compartment temperature is at best a secondary factor to
 performance.  What is primary is the temperature (density) of the charge
 into the cylinders.  Have you any idea what the temperature of the air
 entering the manifold is?  Especially from run to run?  As your turbo heats
 up, you need a better way of cooling the air exiting the turbo -- you need a
 better intercoolor.  I would put my money and effort into quantifying the
 air temperature after the intercooler, and reducing the intercooler exit
 temperature of the air as much as possible.>>>>>
  
    I agree, it is easy to draw causation from correlation.  There are many 
factors that affect the consecutive 0-60 run, engine compartment temp. being 
one of them.  The first step would be to measure intake air temp after the 
intercooler to see if you are really loosing efficiency...
