GS,
Yeah Ive been harping on the "flow detriments" in the stock manifold for a
while Sheesh. I posted some pics on the DML. I ended up fully blocking off
my intake and taking the dremel to it in situ (talk about time spent in
masking and clean up...) It blended nicely into the "wall" but I keep
thinking more profound changes need to be made for higher intake velocities.
Like the MPI manifold :^) BUT: It appears the injection parameters, once
the comp has learned, are "tuned" to the intake/exhaust system (IMO so
far...) to drop off @ around 4700rpm... Need more fuel @ WOT!

Well Jules was right, My TBI was mounted too far to the
left side, causing a missalignment with the intake. Let
me take a moment and say I'm very disappointed with the
quality of machining on this beer barrel intake. looking
down through the ports They left a ridge (almost 1/4")
in the intake path, no dought causing all kinds of airflow
(CFM) problems. DML'ers should do an alignment check for
sure. You may cringe at what you find! If the MPI intake
is as good as tests has shown, I'll have to have one if
its a bolt on and no serious adapter problems.
