MREV and Stillen 1st Gen installed
i got the 5/16 iso thermal mrev plus kit....just installed it last night... the sound is big time sweeeeetness, IMHO of course... although i wish my 05 sedan would sound like the coupe and z....
with copper, you set it and forget it no matter the ambient temps....
with standard isothermal, you have to install an inline coolant control valve and adjust according to ambient temps... if i recall correctly, flow on for ambient temps below 55 deg F, and flow off for ambient temps above 55 deg F...

I had an interesting thought today. Since I have two g's, I thought I might "borrow" Cheryl's MAF and put on my car. Can anyone see a problem with doing this?
Before anyone asks, I don't think it will do any good. But there is a possibility, however slight, that my MAF is somewhat fouled and possible reading incorrectly, though still within tolerances.
Thoughts?

That is if your boss allows you to borrow hers.

Update
Well, after several months of speculation, I finally got it back on the dyno. This time it was at a different place(another dynojet, but different model). I'm not going to directly compare the numbers from one dyno against another, but the main reason I went this time was to see if my a/f's had changed, or if another dyno had more accurate a/f measurements. The only difference between my current configuration and the last was that I have removed my crawford cats.
I was the last car of the day, and other than tig488's aps st coupe, the only import the whole day. My first pull was in fourth gear, and it netted 249/238. The next pull, also 4th gear, netted 250hp. The last pull, in 5th, yielded 253/244. On the first pull, we noticed a very slight knock right at torque peak, but never heard it again the rest of the day. Overall, my a/f's were exactly what they should be: they started at around 13, climbed to mid 13's from 3k rpms to 4k rpms, then dropped back down to the high twelves near redline. Not only that, there were no erratic spikes or dips in my a/f's as compared to the last time I dyno'd(at the other place).
I have a techtom on loan, and used it during the dynos. The weather was pretty cool, in the low 70's(high humidity; raining outside), so my coolant temps never reached more than 177 at idle with the shop's big fan blowing. Intake temps never exceeded the low 80's; so roughly 10 degrees greater than ambient. I watched the timing during the 2nd run, and when the operator got on the gas, timing dropped to 24 degrees, then proceeded to slowly rise until it reached 30 degrees at redline. No hiccups, or pulled timing. It ran exactly as it should.
The guy running the shop, Blake, was really cool. The other place is more of a "get-you-in,get-out-out" kind of shop, but this guy would talk shop between runs. He was really blown away by the car, and kept bringing up other g's and z's he's dynod for comparison. He kept asking me about what the differences were between the sedan and coupe, and then had all kinds of questions about why my 05 put down such great numbers. Before me, the best numbers any of the NA g/z's have pulled was a 237/233 (a local 5AT 350z). Granted, he's only dynod like 10 or so NA z's, and maybe 5 NA g's, but that's a strong statement.
Next, I'll have to put my cats back on and go back to his shop to see what happens. I'm less concerned with if they produce any measurable gains, but more interested in seeing their affect on my a/f's. It's still unclear whether my erratic a/f numbers from last time were a result of the cats, or the measurement equipment.
Unfortunately, I don't have any graphs to share just yet. Blake tried mailing out the run files saturday, but apparently my mail server bounced them. I'll share them whenever I get them.

This is awesome Trey. Can't wait to see them. Your car peak numbers are at what my car did. 255 and 244 my car did here.

Well, I have some bad news on the dynos. Blake sent out the files again, and I still have not received them. So I started spelunking through my mail server logs, and found a copy of the message. Apparently the server did not want to deliver any messages with attachments named "x.001", "x.002", etc. The odd part is Blake never received a delivery status notification. So I have the text of the message, and the attachments are all base64 encoded, so I eventually extracted the run files. The bad news is that apparently the files were generated from an older version of winpep that my viewer cannot read(my viewer is the latest version 7.1.3).
So, I might just have to driver over there and get him to print out the graphs.

You and me both Andy! I was about to scream with not being able to track down the problem. I had almost decided that we must not be living right or something. LOL!

Updated with dyno charts
Got the dyno files over the weekend. Fortunately these were not corrupt, and I was able to export the graphs.
The first graph is all three runs(4th gear, 4th gear, and 5th gear). The second graph is 5th gear by itself.
You can tell that my a/f's are just fine.

I can't email you; it will be blocked. Earthlink likes to block incoming messages from class c ip addresses; earthlink thinks my ip comes from a dhcp block, and by extension, that I'm a roaming spammer.
So... you can download it from here:
http://bytemellc.com/walker.zip
Now, overlaying them onto your plots won't really make much sense. For example, if you graph time versus speed, you'll likely see a large difference. When I got these and plotted time versus speed against my previous runs at the other dyno, I observed that it took roughly 2 seconds longer to reach redline in 4th gear at this new location. Granted, the two dynos are different model numbers, but that tells me the drum at this new location is heavier.
