It was very nice to meet you all, hope you had a good trip home.
Mine was the only BRZ - I feel special!!

Great to see you guys and thanks for coming!

The fuel trims have greatly helped drivability and the car is easier to control at traffic crawling speeds now.  Once properly underway, it feels much like before except there is response to a decent prod at any speed in any gear.
It almost never needs flooring - just a good prod and the speed builds quickly, something I remember my supercharged Honda doing.
I honestly wouldn't want or need more power than this.  It's very well matched to the chassis.
Will report on average mpg once the gauge has settled into a near-final reading.

The mpg is settling down close to 30mpg (currently 29.6 and slowly rising).  That compares with 35mpg before the supercharger.  I've not been using the power all the time, obviously, so it's a real-world idea of what you're likely in for if you go the supercharger route.  About 5mpg loss.  My daily commute is mostly motorway and fast A roads.

I was going to wash mine but it hardly seems worth it!
See you all Sunday.

I buy from ProTyre and they rotate their tyres quickly due to being a big operation. Their price for PS4s is also very good.

If you have the same tyres after five years, you're not trying hard enough!

Michelin Pilot Sport 4.

Do you have the Primacy tyres? They will break traction in the wet at a moment's notice.

Hard to tell at this early stage as the battery disconnect reset things. Motorway cruising doesn't seem hit too hard but it is drinking more than before. My guess is the average will drop from 35.6 to the low 30s.

Both the car and I are doing some learning.  I think the ECU has settled into a better throttle response and I've learned to be very gentle at low revs.
Together, we're much smooooother now!
Had a chance to give it some welly last night chasing a fast Jaguar.  Very impressive and I could easily keep up with him.

Intake temp will vary quite a lot depending on airflow through the intercooler and how much work the charger is doing. 
At the track you should see about  +25-30C over ambient depending on the circuit and driving style, with the Harrop kit. 

Stock brakes at the moment.  They feel adequate to the task on the road.
I did discuss a big brake kit with Scott and will pursue this at a later time after I've saved more pennies.
I also thought I might need wider wheels and tyres but my 17x8 with 225 PS4s seem to cope with the increased torque.  I'd rather keep learning how to balance the car on the throttle rather than having huge levels of grip disguise what's happening down there.

This doesn't show all the runs but is the best one to show power and torque (at the wheels).  262whp (=300bhp), 204lb.ft torque (=276nm).
The comparison lines are for a stock car.  No other mods today, just the Harrop supercharger kit.

First Impressions
There is torque everywhere, especially noticeable from low revs when in a gear higher than I was used to being in.  It's not the shove that I felt in my old twin-turbo diesel, but then it persists and persists to a glorious full wail at high revs.  The responses are immediate but progressive and controlling it even in the wet doesn't cause surprises.  The supercharger itself is so quiet as to be barely there and, unlike my previous Sprintex, there is just the sound of rushing wind at high revs telling me that induction is being forced. The exhaust note, however, is more liable to be noisy when acceleration is demanded at low revs (this may be especially with the UEL manifold).  Cruising on the motorway is no louder than before.  There is a lack of smoothness just above idle when pootling in traffic - it's a matter of learning the new throttle response which can feel a little on/off at first.  This is where the map feels most different from before.
Overall, the car feels like it wants to go at any opportunity and advanced planning for certain overtakes just isn't required any more.
The installation looks very OEM, you could easily believe that the car came like this from the factory.
Pros
Torque across the rev range
Fast responses
Lovely acceleration note at high revs
Overtaking in 5th brings a smile every time
Feels genuinely rapid now
Cons
The exhaust note can be anti-social when giving it pedal at low revs
Difficult to be smooth in stop/start traffic
