Gents,



I am doing the higher power ground runs now, and am only able to run for
about 5 minutes before reaching 195* or so.  I=92m looking for ideas on how=
 to
extend the time for each ground run.  I was thinking of adding a spray bar
like others have discussed.  My thought was to drill some holes in some PVC
and connect it to the garden hose.  Then put it in the intake in front of
the radiator.  I would have to run the hose out the front and clamp it down
so it doesn=92t come close to the prop.



I=92m open to all ideas though.



I=92ve attached a picture that shows my radiator and duct work.


Thanks,

The garden hose idea works fine on a race car for a 2 hour breakin on a
fresh engine. The fine spraw keeps consumption low.

High power settings more directly affect oil temps. Oil temps seem to track
throttle settings exactly.

As they should. Water temps less so....
