air temp affects performance

[ron.v]

Is it just me or doe,s the old girl seem to perform better (the car that is )when the air temp drops.

Cooler air is denser so it helps her breath better with the increase in oxygen.


It can also work for your car too

Now how can i re-route the air con (thinking out aloud)into the bedroom that is.

You are not imagining things. Most cars run better with cool air. Too much heat can cause fuel vaporisation, and with our wonderfully insulated engine bays this can be a serious problem. In some cars (not just TVR's) the air intake tubes and fuel lines are wrapped in heat reflective material and in the extreme Max Power specials, refrigerated fogging via NO2 or CO2 systems are used to produce fairly large power gains by cooling the whole intake system.

You're right, and I hate it when I get all geeky but its known as volumetric efficency.

You have my full permission to take the pi55

It's already done. The fuel return is passed through the air con system to cool it.

Most of these Max Power specials are turbo cars though. Cooling the whole intake is system is critical for turbo cars and can produce significant power gains.

The gains for NA cars is a lot less but it still helps.

And here's one I prepared earlier! Piccie
