Dear friends,
My Father and building partner are clipping along on our fuselage and
have ordered our finish kit recently. We have not yet bought a motor
but we are considering the superior xp360 injected version. It is a
parallel valve with a vertical induction. My question is how much
drag does the chin scoop create with the vertical induction?
Does the slight boost from the ram air on a chin scoop version outweigh
the lack of drag from a non chin scoop cowl that is used with horizontal
induction? Does anyone have any hard numbers to compare the 2 cowl
versions?. I think the xp360 can be converted to a horizontal draft
induction but is it worth the bother? Any comments would be
appreciated. The bottom line is given the same motor which cowl is
faster, chin scoop or non chin scoop?

Norman,
Thanks for sharing this with us. I ordered 2 seat heaters from Smarthome. I'll
let everyone know how they work whenever they get here. Supposed to ship mid-
February.
I plan to cannabalize them and install them in the Rocket seats. Should eliminate
my concerns about not having a rear seat heat duct.
That Canadian Tire store must sell everything!
Thx,
Vince

Want heated seats right now for $30 USD? Check out
http://www.smarthome.com/9290.html
if you have a spare cig lighter socket to plug it in. They are seat covers that
you can put right on top of your seats. I think some one could take a pair of
these and some foam and have the wife sew some fabric to the sides and bottom
making them into custom heated seats. What do others think?
Canadian veiwers can get a product very simular at Canadian tire for $80. Go figure.
These guys are making a simular product for $50

Shane-
On my harmon rocket with an IO-540 direct ram air induction nets about
1.2 in of manifold pressure. On a 250 hp engine this is around 10 hp! It
is not the aerodynamics of the cowl I am speaking of but the ramming
effect of having the throttle body facing directly into the on coming
airstream that makes the difference. When I switch from filtered
air(which draws through a foam motorcycle filter inside the cowl) to ram
air I can see the increase on my digital mp gauge. A friend with
another rocket switched to the direct ram air induction on his plane
after flying with the typical vans/Rocket filter duct induction and saw
the same mp increase and corresponding speed improvement. You can buy a
90 degree induction elbow from John Harmon for less than a hundred
dollars if I remember correctly. Call me if you want to come by and see
all this in the flesh on my rocket.
