A law that describes the relationships between measurable properties of an ideal gas. The law states that P × V = n × ® × T, where P is pressure, V is volume, n is the number of moles of molecules, T is the absolute temperature, and R is the gas constant (8.314 joules per degree Kelvin or 1.985 calories per degree Celsius). A consequence of this law is that, under constant pressure and temperature conditions, the volume of a gas depends solely on the number of moles of its molecules, not on the type of gas. Also called universal gas law

Looks like volume is relevant in the formula to me

Correct with the formula. No doubt this is for a ideal gas.

However your map sensor is the issue , I should of explained it better. A map sensor cannot measure air volume and air speed. You can have a system where you have air speed and volume and no pressure , this is where you fall into trouble using a map sensor. Also map is a fixed table, AFM is actual

So the short answer is that MAF provides you with a more stable tune. Less variation due to subtle changes in air temp and atmospheric pressures. I'm probably switching back to a 4" MAF and a ford lightning sensor with my next setup for that exact reason.

That is unless your going to be doing something radical that uses MAF and MAP...

    • I thought it could be an issue because the standard plate was flexing when stressed. Maybe the original gear set will hold a bit better without flex? Last time on the dyno it made around 670nm at the hubs. Now it have bigger turbo and better intake but have not been on a dyno yet. The car is being used from family trips to drag race events. So the shifts can be a little violent. It is grinding if I shift to fast so was thinking I should overhaul it soon.
    • From the factory on RB26s there's a fitting on the intake manifold collector/"plenum" that provides pre-throttle boost signal. That's how they did it back in the day, I figure it's fine to replicate it.
    • I would be surprised if that wasn't the issue. It's probably telling you, that even if you remove the plastic liner, you may have some other clearance issues that may occur too in some scenarios. IE, tyre to guard. It looks like someone has already rolled the lip, but you may still have issues in the future IE, turning and hitting a bump etc. The fact it changes how bad it makes the noise when you are going backward vs forward is highly indicative that it's the tyre rubbing. They do make a terrible sound, even if you're only pushing a project car that has a liner hanging down on a tyre!   Has the car been lowered? If it has been, what is the measurement from the centre of the wheel hub to the lip of the guard straight up?

    • Mark's a bit smarter than people give him credit... He'd convince the person that is to become dead, to drive him to the forest first. That way his car has no evidence in it, and he's free to dispose of their vehicle permanently how he sees fit too...
