Ok folks,
Fired up the engine with the
new intake with the polyurethane resin
casting plenum/throttle body - Fuel
injector mount using Paul's manifold
casting. The good news is that
while I don't appeared to have picked up any
performance at static (didn't
really expect to as I put on shorter and
bigger tubes which should have
raised the rpm for best torque over the old
system), but on the other hand
the plastic plenum didn't blow up either
{:>).
Static on runup was 5400 rpm
with air temp at 80F and 100% humidity.
Idle would not come down below 2200
rpm indicating an air leak. OR the
3/16" dia hole in the hugemongest
throttle plate needs plugging. I stuck my thumb over
the
hole and the rpm did drop, couldn't tell how much as could not watch the
tach
while doing that, but it sounded like a couple hundred rpm. I'll
use some
JB weld to plug the hole and then see.
Here are a couple of photos.
One of my objectives was to reduce weight
and I have shaved off 12
lbs off the old intake with the new one weight 11
lbs with manifold
casting, tubes, plenum, throttle body, fuel injectors and
fuel rail.
. Another objective was to clean up the exhaust side of the
block for
later putting a turbocharger there. As the second photo shows,
plenty
of room for the turbo now, note how snuggly Paul's casting bolts up..
Note
the oil on bottom of flange from cutting and refitting oil pressure
sensor
line.
