Ihave the original from my car for sale, 2006 wrx

really? get urself a new one then

woo hoo

Any one want me to get prices for winter checks and oil and filter changes? We may get a good deal here. Mervyn has already volunteered to put the code readers on for thos who want that.

It has all gone quiet here

good effort

Very dark it is too.

hehehe

Get a nice new back box. It will make a big difference and not cost too much. I have a ninja 2 from scoobyworld

So on a nice day it could be nearly 260 then!! Maybe it has already been fiddled with.

Increased by 15 bhp from your last rolling road? What was the temperature, pressure and humidity at that one? Or are you say increased 15bhp from satndard? If so you could actually have another 15 bhp on that if it had been checked on the day mine was remapped

There was some argument about some cars underperforming at our recent rolling road day and Martyn tried to explain about it. Not sure if everyone understood why their cars may have been down on power that day. Mine was mapped at 27 degrees Celcius but the rolling road day was 13 degrees and I lost just over 13 bhp. I thought an explanation might help some of you undersatnd this so I researched it on the net and found the following: So some of you may get even better readings on a warmer day with different humidity and air pressure. Our temp was around 13 - 14 degrees and the pressure was 1014mb sorry but cannot remember the humidity. (29.92" of mercury is 1013mb if my memory serves me right) WEATHER EFFECTS: First of all, figure 60deg F, zero humidity, and a 29.92" barometer as 100% air density - AKA the "Standard Day” Now that we have the Standard Day figures, we can get to how each of the three measurements (temperature, humidity and barometer) affect air density. Actually, there is a moderately involved formula for calculating air density, but I'll skip that and get to how you can closely estimate pluses and minuses. 1. Barometer readings have a linear effect on air density. That is, if the barometer goes up or down 1% from the standard reading, so will air density. Therefore, a barometer of 30.22" gets you to 101% air density, 29.62" nets to 99%, and so on. 2. For each 5o change in temperature (away from 60o), you get about a 1% change in air density. Therefore, an 80o day means 96% air density, and a 40o day means 104% air density. Note: This is *not* linear, since the calculation has a base of absolute zero, but it's close enough so we don't have to worry about it. 3. At 60o, jumping from zero to 50% humidity will cost you roughly 1% in air density. However, that same 50% humidity at 90o will cost you more than 2% in air density. The reason for this is that it requires a *lot* more water vapor to get you to 50% humidity at 90o than it does at 60o, since air can hold more water as it's heated - like sugar in your coffee or tea. Hot tea can hold a *bunch* of sugar, but iced tea can't hold too much. "Relative humidity" is expressed as a percentage of water in the air compared to how much it *could* hold at a given temperature. All 3 figures need to be juggled. As an example, a 50o day with 50% humidity and a 29.62" barometer nets you to just about 100% air density, since the 2% you pick up in temperature is offset by the losses you incur for the barometer drop of 1% and the humidity loss of 1%. Now, how does air density affect power? This is also something that is moderately involved, but figure around 75-80% power delta compared to the air density delta. That is, an 8% drop in air density will likely cost you somewhere around 6% in power. Actually, barometer changes give you something right around a 1.2-1% swing in power, temperature changes give you something right around a .7-1% swing, and humidity is near 1-1%. In practice, temperature is likely to be the biggest variable, hence the 75-80% "rule of thumb". In general, temperature has twice the effect on the car than humidity does. If the humidity goes up 2 points, it affects the car the same as if the temperature goes up one degree. And vice-versa if the air temp goes down. This is a rule of thumb that holds fairly well for all cars. Anyone still awake? I hope that helps some of you understand what you saw on the day!!

So SIDC stands for Subaru Inbred Drivers Club

Just so you all know, Merv has a BRZ for sale at Ashburton Motor Works just off the A38. Ashburton Motor Works is the local Subaru Dealer for those not in the know or new here.

Please sign in here https://www.facebook.com/home.php#!/events/404161342990869/ Hi all, I have now got confirmation that Subaru UK are supporting our open day at Ashburton Motor Works on Saturday 1st December. The event is here https://www.facebook...04161342990869/ please sign yourselves in and if we have enough numbers the buffet lunch will change to a Hog Roast Free winter checks are there on a first come first served basis for UK cars only (not JDM or other imports I am afraid). There are parts available for sale too from the Pro R Range (like suspension and filters etc) and a Show and Shine with prizes. Cars available for trips include the BRZ, Cosworth, XV and STI Pro R. Please support this event if you can. Local accomodation is available too. You can PM me for more details - especially those travelling from afar. This is a family orientated event so bring the kids too.

I had mine done at 5 years/ 38k miles.

I have an afterburner centre section and Ninja2 back and it is nice

Yep

And these are the results

Was nice meeting you mate. WOuld have liked to see yours on the dyno tho, would have made the day having one of every version on the rollers. Get you next time.

Although that is a bit unsavoury, the fact is that undeclared modifiactions to your car effectively mean you are uninsured! People need to remember that the internet is a VERY public place and if you post something anywhere you need to be aware of the consequences.

Nice one mate, I hope you are hapy there

No probs mate, pop down and see us later if you get time.

Any more who want to come along please do. £25 and a food van will be there too. 10am start but no need for everyone to be there straight away but do be there by 1pm!!
