OK so I've looked in the 'Mods Worth Doing' thing and I still don't know if this question has been answered or not.

Brought on by a trip from Sheffield to Hull to Gainsborough and back to Sheffield, is there anything that can replicate that 'cold winter morning' feeling of driving a turbo charged petrol motor?

I draw your attention to the title of this post...

Easy..

Move to the North Pole

know what you mean. my car was flying this morning.

is there anything that can replicate that 'cold winter morning' feeling of driving a turbo charged petrol motor?

Or... How can you lower the temperature of the air getting into the engine?

An improved intercooler is possibly the answer you're looking for?

Exactly.

More suggestions please.

Thinking about it, isn't it air into the turbo or intercooler rather than just into the engine (writes a technical moron. And what is an intercooler anyway?)?

Cold air induction...cold air will expand more so give the pistons an extra shove. Some DIY piping should be able to redirect some cold air into the intake...

As I understand it.....cold air is denser and therefore gives a better burn hence more power.

So you need the inlet temperature of the air to be as cold as possible I guess.

cold air is denser allowing more air into the cylinders

It's not that you get a 'better burn' in fact it might be slightly worse due to the lower amount of movement of the fuel molecules and the oxygen molecules.

What does make the difference is the volume of the fuel air mix going in compared with the volume of the hot combustion gases coming out. This is doubly true when a turbo is effected as well.

Keeping it simple ,gases expand by 1/273 for every degree centigrade they go up in temperature (don't worry about the 273 bit its due to the temperature that it all stops at which is -273C) so if the temp of the gases go from 2c to 300c the volume change is much greater than 20c to 300c

Crudely this would mean about 5% more change at the low temp compared to the high temp. or about 10Hp on a standard Octy RS.

Water is great for taking heat out of a system like a car inlet hence water sprays etc for cooling.

I hope this is helps.

drive late at night instead :p

seriously though - laggin the turbo and downpipe will reduce under bonnet temperatures and cold air feed is only gonna help :P

anyone tried water injection yet?

Front Mounted InterCooler

OK. So I understand that.

Can you imagine a car with no other mods other than a Superchip and a DV? If so, how do you rate the water spray and the 'front mounted inter cooler' whatever one of those is?

hello, if you guys have more questions like this you might wanna check out www.howstuffworks.com

it taught me loads of stuff I didn't know (well, I didn't know anything about cars and now i roughly know how every part works).

They also explain turbo, intercooler, ...

Sorry. FMIC?

Standard placement for the small intercooler in the Octy/Fabia is near the passenger side front wheel arch (IIRC) A Front Mounted Intercooler sits below the radiator where it can obviously get more airflow over it and therefore cool the gas inside more. An Intercooler is like a radiator for gases rather than liquid.

Spraying a fine mist over the intercooler has the same effect as spraying a spritz on your face on a warm day, as the water evaporates it further cools the air inside the intercooler.

Lagging the pipes keeps the temperature within from being affected by the hot engine outside

Anything else?

have a look at demon tweeks catalogue page 229

cry02 cryogenic intake system

uses 5kg co2 tank to lower temp of intake/fuel charge by to to 60%.can be expaned to also cool the intercooler and fuel bar.The intercooler sprayer sprays the liquid co2 straight into the intercooler fins.very impressive......

yours for a mere

also i just been reading about a composite gasket for the 1.8t that reduces intake temps etc etc this is what it said

Gives you more power in your 1.8T by reducing the temperature of the incoming air to your engine with an insulating gasket that radically reduces the heat transfer from the cylinder head to the intake manifold. This gives you cooler, denser air for more horsepower and performance from your engine.

Made from a high performance polymer, PowerGasket

I believe Paul ffelan has a PowerGasket on his, but I might be mistaken...

Rob.

I own a Powergasket....sitting in my dining room waiting to be fitted.

How's about passing IC water spray water through a chiller (re-route from car a/c for example) then pass this over the IC fins. Hey presto chillier and denser charge air.

Losses caused by running a/c compressor might cancel out power gains but JMTPW...

Or howabout just rerouting the a/c air flow so that it chills the air intake?

I'm fairly sure the Greek chaps have these too.
