[T3] Tire height/secondary oil pressure loc. ???

["Erkson, Toby" <toby.erkson@intel.com>]

First question for the stockers:  Would someone with stock tires and stock
ride
height please measure the height of their front tire (ground to top of
tire),
please?

Second, anyone can join in:  Where is the better location to put an oil
pressure
sender for a secondary oil cooler?  I currently have mine located after the
secondary cooler (I still have my stock cooler and sender in their stock
location).  I've noticed what looks like to be a percentage difference in
oil
pressure after the secondary and before the primary.  I figure this
difference
is due to the unsmooth bends the oil must take and possibly a difference in
the
senders (big "if").  Engine warmed up and at cruising speed (3600rpm=76mph)
the
oil is roughly 30psi on both gauges -- maybe a *tad* higher on the secondary
gauge.  I was wondering if maybe I should be measuring the 'before cooler'
pressure, since the pressure is basically the same now, to see if there is a
pressure difference.

Currently, the oil takes this path:

     oil pump -> oil filter -> oil thermostat -> primary (stock) cooler 
                                     |           ^                      
                                     V           |                      
                             secondary cooler -> +                      
                                             
                                             
The thermostat directs most of the oil to the primary cooler during cool oil
temps and will direct *all* oil to the secondary cooler once the oil goes
higher
than 170-degrees F.  Either way, oil will go into the primary oil cooler.

Do I really need to monitor the oil pressure in the secondary loop (before
or
after cooler)?  The cooler does get hot and I know it slows down the
temperature
rise of the oil, but the oil does get pretty darn hot nonetheless.

Experiment still in progress,

getting ANY email until Oct.5, unless Phil D. or Big Al (and maybe Tom C.)
can
act as a messenger).
