Hi all, I'm planning ahead here
Anyone have any thoughts about using one of these cowls compared to the
stock Van's item?
I seen some posts that claim performance but at the cost of being harder
to fit.
Thanks
Frank

I would consider using one next time. Thing is, you need an extended hub
propeller if I'm not mistaken. Wonder how much additional stress that puts
on the crankshaft. It wouldn't hurt CG-wise. Even if you don't use the Sam
James cowl, an extended hub prop would do wonders for allowing more
clearance for horizontal induction goodies...ram air inlet, etc. I can tell
you that making the ram air inlet work with a compact hub Hartzell was
interesting...
Back on topic...they sure look pretty with the nose extended with the James
cowl.
Have you read Randy Lervold's writeup on it? IIRC he said he might not do
it that way if he had to do it over. Apparently it added considerable time
and labor to the build process. http://www.rv-8.com/Cowl.htm

Interesting...I saw the write up and it sounds even with the mold
corrected it is probably at least SOME more work...Hmm as you say Dan it
looks hot!
Thisnk I might check out the 4" extension and if Aerosport are happy
with this if required,,....Oh and yes, that Van's will refund the cost
of the cowl coming with my finish kit...:)
Thanks

I installed one of these on an RV-6A. Lots of hard work, but the cowling
worked perfectly, I also made my own NACA duct on the side of the cowling
for the oil cooler. All temps would stay normal even in high power slow
flight. I did not use the 4" extension, still up in the air about that,
With the extension it may be a bit easier. If you would like a picture just
send me an email at NOEL@BLUESKYAVIATION.NET

Will James just told me he thinks a 4" prop extension will limit the
motor to pull about 3.5 G's...Ouch...Don't like that.
I could go with an updraft and have no extension but I'm not sure I like
that option either....hmmm
Any thoughts?

Will James worked with me to come up with a version of the cowl for my
**carbureted** RV6A O-360. Maybe this would help you.
This version would not require the extension and in theory should be easier
to fit. I have the cowl but won't be working on that until it warms up.
If you check his site, you will see a picture of it.
James

I just recieved the Sam James rotary versioin for my 7A. I plan on
using a Mazda RX-8 engine and Tracy Crook's PSRU. The workmanship on
the cowl is great. It has the shark air intake below the spinner. I
won't be installing it until this spring.

I had Noel Simmons install one on my 6A. I would definetly recommend a prop
extension
that Sam James recommends during installation. Noel chopped off approx 3-4"
to make it
fit and in doing so had to mold blisters in front of cowl to accomodate
starter & alternator.
Added a lot more cost to installation. Anybody interested in pics e-mail me
off list I'll forward.
