oldmandon 1 Posted September 28, 2011 Report Share Posted September 28, 2011 When I met up with ThermalIP4, we did some data logging on my car. One of the settings we monitored, was the MAF, specifically air temperature and volume of air moved.First thing was that my MAF maxed out at literally just under 60 gallons (?) litres (?) of air per minute, and it was decided that the MAF couldn't keep up with the volume required. What have others found? What would a GOOD MAF register?Secondly and more interestingly, was the air temperature, we started with something like 56 Celsius initially it went up, then it went down and down, I think we had it down as far as 34 Celsius, it could have been more, I was busy driving, so couldn't see!! Now ThermalIP4 said that the air temp going through my MAF was some 30 - 40 Celsius COLDER than his readings on his car!!? When I was discussing this with a mechanic friend, he said that you didn't want the air TOO cold as this could cause different problem s.My question with regards the temperature is, What would be considered TOO cold? and has anyone else done this and what figures did you get? Finally how MUCH of a difference does it make in the REAL world?Over to all you tuning bofs!!!!!! Link to post Share on other sites

bells 5 Posted September 28, 2011 Report Share Posted September 28, 2011 i remember the manifold on my 73 beetle freezing because the pre heat pipes from the exhaust were blocked and it was only october time ! why is petrol cold ? Link to post Share on other sites
bungy 2 Posted September 28, 2011 Report Share Posted September 28, 2011 Barometrics affect a cars performance and the volumetric density of air. Pressure has a direct relationship to temperature. Link to post Share on other sites
b road blaster 0 Posted September 28, 2011 Report Share Posted September 28, 2011 colder and denser (sp) the air normaly the better a engine will run hence why most turbo/sc cars run big intercoolers to keep the inlet temps as cold as possable Link to post Share on other sites
