Drivetrain RMW Header Awakens The Dead!
I'm pretty sure Jan is still tuning - just takes someone organizing the events with enough people (12-26) to make it worth his while. We did one here in NC a few months back. I'm counting on him doing something sometime before too long - I'll travel anywhere DC (maybe Phillly) to Atlanta to have it done.
He's also getting very close on having his remote tuning setup ready - so he can send you a device, you can go to a dyno locally and have it tuned by him without him leaving California...

IT'S MOVIE TIME!!
Here are some scenes from a little buzzing around town today.My 1st attempt at I Movie.

Let's call it "a progression in sound".There will be a time when you will long for more than just supercharger whine(at least I did).I love it!
amen brethren....ITS RIGHTEOUS!
Ha, yeah I understand. I guess my concern was just the noise level. I personally don't mind being a little loud but I live in a residential neighborhood and am maybe hyperworrying about the neighbors, and maybe attracting cops attention. However, I'm sure its only really loud if your pushing the car. Can you still maintain a relatively low profile if you just drive around normally or is a little bit more loudness an aftereffect of the header? Maybe you can post a quick video of you just driving to the corner store without slamming it? 

Thou shalt not drive in a luke warm fashion....amen
.....lets just say I'm aware of popo's when mashing it hardily.
One can certainly drive "sedately" with the header and it's not outrageously loud - or even attention grabbing. Though, personally, I'm not "one"... whoever that is...
But if you throttle and shift like an old lady, and keep it under 3000RPM, and avoid WOT... it's not very loud.
But at WOT... boy, oh boy...

thanks guys. Def sounds good, quiet and loud on command!
Here is are two videos shot the same day of JCW Minis, both with the windows open. The first video is a stock JCW and the second is mine with the RMW bits, definitely a lot louder under power

Nice
davisflyer and I had some big fun at VIR that day.
What exactly does a cam do and how does modifying it affect performance? I understand the exhaust components but maybe one of you guys can elaborate on the cam.
The camshaft(a rod with little oblong cams on it) directly affects the opening and closing of the valves.An after market camshaft can optimize this relationship(valve stays open to receive more fuel/air mixture) for more power.....But I am learning like you.
Camshaft reading:
http://www.howstuffworks.com/camshaft.htm
Engines operate in a very wide range of RPMs... a camshaft is a compromise to provide good performance at all rev rates. A performance camshaft gives up some smoothness of idle (and introduces what some folks call "lope") to enable the engine to "breathe" better at higher RPMs - breathing better is what most performance mods (intake, exhaust, header, ported head, big valves) are all about... more air per cycle = more fuel per cycle = more power...all else being equal (which it never is... )
The howstuffworks article does a good job of comparing a "standard" cam with a "performance" cam, and discussing the impact.

To add to the above statement, the RMW camshaft is fairly mild, so it retains a stock idle. What it does seem to do is give a decent increase in the mid range, where you normally drive. Different camshafts have different personalities, and I don't think it's necessarily right to compare them as people have unique driving styles and uses. The reason that the RMW camshaft + header works better as a system is that the camshaft is more of a mid range camshaft and as it starts to taper it's performance, the header takes over to redline. Thus, as a team, they give you a greatly expanded power range.
You nailed it

... everything except "retains stock idle"...
it definitely doesn't have a major lope like high-end cams do... but mine has this very mild, kinda sexy lope that definitely isn't stock. Most folks won't notice - but it bounces around between 725 and 800 RPM... you could raise idle just a bit and it would be smooth, I think.
