Rowlandyou could make a plug from blue foam, wrap it with grey duct tape an
d use that. Shape is not too critical.Graham

Hi Rowland,Glad to hear you are on with it, smart thing would have been to
call or email me directly with your question ?All pretty straight forward,
no need to do any glassing / cutting of the cowls, I designed and manufactu
red them so you don't have to ! If it takes you more than a morning to fit
them you are doing something wrong !Air to the carbs is taken from under th
e cowl, no chance of water ingress via a NACA scoop=C2-when parked.. Pref
ered filters are the conical K&N's direct on the carbs, but the Europa airb
ox set up will work. The airbox / NACA set up was needed with the standard
XS cowls as it gets hotter than hell in there with no through airflow.=C2
-Air temps inside=C2-my upper cowl=C2-taken at shutdown after a 2 hou
r flight were below ambient, nothing above the baffles got hot enough to da
rken=C2-the 40=C2-C bar on the=C2-temp' test strips.The baffles will
direct cold air all the way to the rear of the cowl, and with the top of th
e tunnel gap blocked off with a baffle, little heat build up there after sh
utdown. Baffles also prevent the exhaust headers cooking the fuel in the ca
rbs.I'm sure you had copies of the baffle templates [ baffles made from sof
t alloy] if not I can send you a set. With this installation, you can run o
n the ground at 2,000 rpm all day, and do the 5 minute WOT run for the LaaL
aaLand pre 1st=C2-flight test without burning the cowls or chucking the c
oolant overboard=C2- [BTW use 50/50 antifreeze / water, not the ''other s
tuff'' ]As you only had the cowls [ not my complete kit] just follow the Eu
ropa FWF Manual as far as mounting and plumbing the engine, in the same pos
ition as the XS Europa kit.Cheers,Nev=C2-=C2------Original Message-----

Subject: Europa-List: top cowl carb air inlet
I=99ve bought Neville Eyre=99s cowl set and I am wondering how
to get the air into the cowling to the plenum chamber for the carbs.
The Europa manual describes making a NACA duct on the top cowl to connect t
o the plenum chamber, at a marked position. If I understand the manual corr
ectly, it appears that a buck or splash moulding is supplied with the facto
ry cowl set. It is pushed through the cowl from the outside and the duct is
laid up inside the cowl against the splash moulding.
Neville has not supplied anything to make the NACA duct for the plenum cham
ber. Obviously I can work out the position on the cowl from careful measure
ment of the plenum relative to the firewall, but I don=99t have any i
nformation or pattern for the shape and size of the NACA duct.
Does anyone have one of these splash mouldings from the factory that I coul
d borrow, please? I don=99t need it right now, but want to make sure
I have some way of dealing with this problem when I come to it.
Or, if I=99m not understanding how the NACA duct is made, can someone
please explain it to me!
in friendship
Rowland
