I concur with all your points about the Vans vs James cowl. I need to get back on mine as soon as my wiring gets tidy'd up somemore

The true parameter of interest is performance

A number of people have compared the James Aircraft cowl to the Van's and said the James is of better quality. I'm not so sure that is true.

In the looks department, ADVANTAGE James cowl. That thing looks fast just sitting there. IMveryHO!

The real comparative interest is in performance. To my knowledge (I have all three years of data in one Excel workbook) There never has been an RV-9 in an SARL cross country air race with either cowl so I guess we will never know. When you jump in the arena we will get some baseline data for the RV-9 powered by a "360" with your prop selection.

Bob,
The bummer of it is that with the engine and prop change going on at the sametime my old data is no good.
Oh, I'm making a Larry Vetterman belly fairing while I'm at it. That is supposed to be good for up to five mph.

Bill - when you make your Vetterman exhaust faring, can you post some good pics of it?
Thanks!

Yes, I'm very interested in the belly fairing results as well!

Update time
Gang, I will take and post pictures of the Vetterman's fairing, when I make it. Right now it is just a stack of epoxied together Styrofoam. (Epoxy and micro balloons that is.)
Between SnF, my three jobs, and the new boy (well not so new at 18 months), I have had limited time to work on the plane.
Over the last few days I have installed carb, fitted the exhaust, and riveted the doublers to the baffles.
Let me start by saying that Larry Vetterman does a great job on these exhausts! On my old engine, I had to take an O-360 exhaust and trim it down to fit the O-290. Not a big deal but another task. It was a pleasure to simply unbox the exhaust and bolt it in place. Not to figure out where to drill the holes for the EGT probes.
Over the past few days I’ve been playing with the baffles. Man, this new baffle kit is just outstanding! Real instructions, with good pictures, parts that actually fit, and more! Radomir came over this afternoon to kick me in the butt aka kick start me. As he also has a Sam/Will James cowl and plenum, we made great progress and I’m just about to trim the baffles to fit. Then I’ll do some fiberglassing on the plenum just to seal it better. Once that is done, I can fit the oil cool to either the baffle or on the firewall. My preference is to put it on the baffle but space considerations may force the move to the firewall.
A big thanks to Radomir for his help today!
That about covers it.

Pre-OSH update
It has been almost 13 months since my taxi incident and N941WR is getting close to move back to the airport.
Here is what I have left to do:
The oil filler door needs to be riveted in place and the Hartwell latches installed.
The carb heat has to be fabricated and attached to the HIGHLY modified FAB.
I need to modify the mixture so I have enough movement. For some reason, this worked great with the MA3 carb on the O-290 but the MA4 carb on the O-360 is just different enough that it isn't a bolt up operation.
Once that is done, I need to mount my new rectangular EICommander and I want to repaint the interior, while I have it home.
Pictures of the FAB modification can be found here.

Nice work Bill. I'm curious, in the last picture what are the wires coming out of your drain plug?

Engine Oil Heater
Todd,
Here are the details:
It is a 3" long 250 watt oil heater. They are a NASCAR tansmission pre-heater. (One of the advantages to living in NASCAR's home territory).
It is a 110V heater and I will add a plug and run it to the oil filler door later on.
You can order it from: http://www.bsrproducts.com/
Here's the part number and cost from my invoice:
ELX.PH.2503 Probe Heater - 250W 3in Long $49.86
One note, they do not come with a provision for a safety wire, so you need to drill a small hole prior to installation.
