Rotary and General Chit-Chat / Climate Change

Ive not yet understood why the seven estuary unit was canned...it seemed to be a great source of free energy that is completely guaranteed!


There were a number of reasons, the biggest being the ecological impact on the wetland areas upstream which are breeding and nesting grounds for a hug population of waterfowl. The area is also designated an SSSI under UK and EU law. The consultants brought in to do a feasibility study calculated that the construction costs + the mitigation costs for habitat creation for the bird population would make the project a non-starter.


While I am not either an engineer or an environmental scientist, I have worked to support the sector for 10 years. The whole CO2 debate is often taken out of context (particularly by the nay-sayers) and there is a lot of misquoting on both sides of the arguement.

That CO2 levels are increasing is a given, that since the industrial revolution CO2 output has increased dramatically is also widely accepted, that we are reducing the planet\'s ability to remove CO2 from the atmosphere by deforestation is also pretty obvious.

Now the question is what is the effect of this CO2 on climate? As Prof says, it is likely that there is some data missing from the computer models, but I would suggest that the overall premise that climatic shift can be affected by increases in CO2 has some merit.

The problem is that the zealots on the AGW side have made a rod for their own back by implying that man-made CO2 emmissions are wholly responsible for climate change, rather than an additional influencer. So if we continue to push CO2 into the atmosphere at the rate we are, it will speed up an already existing process.

H2O Vapour is always raised by the AGW deniers as some sort of "proof" that CO2 is not the culprit, but while water vapour is certainly a more efficient Greenhouse Gas than CO2, we are still adding to the overall greenhouse and that wil increase the greenhouse effect. Additionally, as the global temps rise (albeit slowly) more water vapour is released into the atmosphere increasing the greenhouse effect further. There is evidence to suggest (as Prof mentioned) that actually we are masking the true greenhouse effect by the pollutants and particulates we have released so as these reduce thanks to improvements in filtration and clean-burning technologies the true effects of CO2 will be seen.

re: renewables, I have actually been one of those to have benefitted from the wind industry, but the problem remains that without a huge amount of research into energy storage techniques we are in a situation where we are trying to create an energy industry based on intermittent power sources! Tidal power is probably the most promising renewable energy source, but for some strange reason the powers that be seem to have nailed their flag well and truly to the wind power camp.

2nd generation RX-7's / 20B FC anyone?
« on: November 19, 2010, 08:15:44 AM »
Another of Tim\'s "top barn projects"! You know the work will have been done to a high standard, but there is lots to do still! I\'d say the shell is probably savable if u wanted to.

Rotary and General Chit-Chat / New Nokia N8 - Very disappointed
« on: October 24, 2010, 10:23:50 PM »
The N95 had shocking battery life, my N86 8MP is also quite bad on batteries, but the Carl Zeiss Lens and excellent resolution on the cameras are WAY ahead of the competition. I am torn between an N8 and an iPhone for my upgrade in December, I\'ll prob go for the N8 (don\'t want to increase my monthly contract to get a free iPhone 4), since I got my first N Series, I\'ve always had a charger in the car and it sits on charge as I commute in and out of work, seems to keep the battery charged ok.

Anything Engine/Performance/Tuning related / 1680cc Injectors on FC
« on: October 09, 2010, 02:03:03 PM »
why 1680s? I\'d fit 1000s all round as they are made to fit the FC fuel rail and you won\'t have the massive step up to the bigger injectors to worry about in the fuel mapping. Unless of course you need the extra fueling 4x1000 is 4000 (4l!) or you have 2x 550 + 2x1680 = 4460 there isn\'t much in it...

Rotary and General Chit-Chat / Rotary Super Cars unveils the Raptor GT
« on: October 06, 2010, 05:27:00 PM »
not really a concept car, more of a low-volume made-to-order car (there are a lot of them that we hear about and never actually see), would be more interested in seeing if the company actually lasts long enough to produce these!

3rd generation RX-7's / Cost of building and installing a 4 rotor?
« on: September 24, 2010, 05:31:45 PM »
reasons for not seeing many probably include:
fuel consumption
unusable power
noise
cost
effort to build
etc etc

And when you can get a reliable 450bhp out of a 13b (way more if you sacrifice driveability) a reliable 650bhp out of a 20b (with no stress on the engine) why would you need the 26b?

3rd generation RX-7's / pics of your blue rx7\'s
« on: September 23, 2010, 08:17:47 AM »
as a 94 car it wouldn\'t be original in innocent blue mica, and looking at the pics I\'d say that was re-sprayed from black. Hard to tell from the pics if it is actually a mazda colour, certainly close to the blue mica

3rd generation RX-7's / pics of your blue rx7\'s
« on: September 22, 2010, 11:07:46 PM »
the two standard blues were Montego Blue (the metallic blue with a greenish flip) and on the later (post 96 cars) there was also an Innocent Mica Blue

2nd generation RX-7's / Suspension options FC - discuss
« on: September 11, 2010, 11:30:56 AM »
there are loads of options: Tein have coilovers and also lowering springs, I had the Tein SS springs on stock shocks for a while, then I got a set of Koni adjustables with Pi springs, which I think are great (cheaper than coilovers too). Pretty sure HKS had a set of coilovers for the FC, not sure if they still make them or not.

I think white on a black car looks good

Rotary and General Chit-Chat / V mount why only on RXs ?
« on: September 08, 2010, 01:30:38 PM »

Hot air rises.....so the warm air from the rad will in theory just rise up and through the intercooler.


Again, this is only a factor when stationary, whereas in an FMIC setup (granted, done properly with ducting, fans etc this should be less of an issue) the warmed air through the IC is pushed onto the rad when moving. Again, it is a personal preference really there are pros and cons to either solution (IMHO the V-Mount is a better option from a cooling point of view), but there are probably more tuners out there who favour the V-Mount over the FMIC

Rotary and General Chit-Chat / V mount why only on RXs ?
« on: September 08, 2010, 12:48:55 PM »
The main issue is around ensuring that the water temps are kept low, the FMIC sits in front of the rad and so you are getting hot (well warm) air onto the rad. A V-mount, in theory, ensures that both the rad and the IC get cool air from the front of the car. You could then argue that the angle that the IC sits in some V Mounts means that it doesn\'t get as much cool air as an FMIC so swings and roundabouts. Mine is a bit of an offset V-Mount with the rad laying almost flat on the underside of the engine and the IC at a similar angle to the original rad mounting, I do have two mig electric fans on the underside of the rad drawing air through the rad from the "V"

Rotary and General Chit-Chat / 2nd Gen or 3rd Gen?
« on: September 03, 2010, 05:04:32 PM »
as everyone else has said, depends on what you are after and what you want to acheive with the car.

The FC is on the whole a cheaper car to buy and insure, but there are a lot of rust-buckets around, remember most of these are UK cars and have been dealing with salted wet roads for over 20 years.

You can get serious power out of either the FD or the FC if that is what you want, but there is far more experience of tuning FDs in the UK.

regarding the weight issue, most of it seems to be in the sound deadening which was over an inch thick in mine!

At the end of the day, the FD is a very pretty car, but there are lots of them around and many are total nails. The FC is a great looking car, but it is a bit retro and if you don\'t like the 80s/early 90s look then you\'ll always wish you bought the FD!

If I ever get mine back on the road, I\'d never want to replace it with an FD, much as I love them, the FC is rarer and just has that cool retro look.

As for handling, you can get the FC to handle as well as an FD if you really work on it, John Goodwin\'s FC is/was a demon track car, but a huge amount of effort went into it

There\'s no way any RX7 can be worth over £20k, just get a Porsche Turbo instead, i loved my last one :3gears-lh
Dave.


I would say the Spirit R justifies that sort of price tag. There are so few of them on the road (2 in the UK I believe) and there were a limited number made so they do tend to hold their value.

Did someone say that they have scrapped the model report?? If not then as has been said, a 2002 car can\'t be driven on the road as you won\'t be able to clead it through an ESVA.
