Talking earlier about cold air feeds to the air box. Hypothetically is it posible to duct air from the cabin aircondioner to the air box hence controlling the cold air feed from 0 to 4?
Just a thought

HeHe nice one mate...thought about it, but flow rate required by the engine cant be supplied by the aircon fan methinks.
You could always mount a fridge in you engine bay and the engine in that! :D

I had a mate a few years ago with an MG Metro. Being young and foolish as we were, we removed the air filter and box completely and plumbed in a nice fat air duct from the heater fan onto the top of the SU carb. It was a surprisingly successful experiment and made for quite a rapid little car. Problems were that the fuel consumption plummeted and as the fan was only a two speed unit it was a bit uncontrolable...

me thinks that the power loss from powering the a/c would cost u more than what u'd create from the cold air .... there is an electrical way of doing it by means of peltier devices but .. not sure if they would be able to make em big enough to cool 200KW of power continuiously
It would not gain as much as it used else we'd have a perpetual motion machine. which would be nice.

Perpetual motion does exist..you should see my kids at the dinner table:(
lol - you mean even though they only get one piece of dried bread a day they keep running around all day?

Thinking laterally about this, i'm not convinced that statement is completely accurate...
IC engines are inherantly inefficient - typically less than 35% of the available chemical energy in your fuel gets converted to kinetic energy to propel the car down the road, most of the rest is turned into heat and noise and a bit is turned into electrical energy. Provision of cold air can give a bit improvement in power output. This is a result of more efficient burning of fuel in the engine. I could see the maths getting very complicated with all the energy conversions and so on and so forth, so i'm not even going to attempt it but increasing the efficiency of conversion from chemical energy to kinetic energy has to be worth a go?
Just a thought.

lmao - DONT turn it up too cold
probably ice up the jets/injectors HEHEHEHE
and would cause mixture problems more than likely
PInk PinK PiNk - is that ya head poppin ? :):):)
Bloody hell its flapper!
I haven't seen you on here for months!
How are you doing?
Amethyst have been a bit quiet since you and Swinny left!

lol quiet or closed ??
