Hi, fellow rotary enthusiasts....We finally finished research and
development on the 90 degree oil filter adapter for the 13b.

CUT

Good work Paul. How much for the adapter?

Paul Lamar

Hi, Paul...The machinist said he charges $42.00 per hour, and it takes 3
hours to make the adapter, plus material.  That would put the cost in

the

$160  neighborhood. When I look at what the Lycoming filter adapters

cost,

or what it costs for the stainless hoses and AN fittings added to the

cost

of the less expensive remote filter kits, I guess it doesen't seem so

bad.

What I like most is that there will be no additional hoses or fittings

to

leak.

Is it done on an NC mill?

One problem is it does not provide clearance for most tuned intake

manifolds.

You are using a two into four intake manifold which I suspect will limit

the HP.

Hi, Paul....the oil filter adapter at present is not done on CNC.  He has
CNC equipment, but said that for a limited number of pieces, it is not worth
the time and effort to program everything.  If for some reason there is a
larger than expected demand, then CNC will happen, and the pricing would
also be lower due to the CNC faster production times.
     The oil filter has not moved forward or aft (in relation to the
flywheel or waterpump end of the engine). It only moves the filter
perpendicular to the length of the engine. I might be missing something
here, but if the tuned intake manifold clears the original oil filter, it
should also clear the oil filter in this location as well, unless there is
to be a large air cleaner or ?
     This certaintly won't work for everyone....It may possibly interfere
with evap. cores on some installations, and intercoolers on other
installations. Hopefully it will be useful to some builders. Thanks for your
interest and input, Paul.

No the tuned manifold does not clear the filter. That is why many of us
are cutting off the filter mount, plugging the holes and using a
remote filter mount. Bruce Turrentine does this routinely on engines he
builds.

Yours might work if you have plenty of room over the engine and under the cowl.
Also it might work on a pusher where the plenum is turned 180 degrees.

It would be a particular problem on the RX8 engine with a 2.85:1 or greater PSRU
is used and where shorter tuned length intake manifold runners are called for.
