MAP Values

[Andy Hogg]

Can anyone tell me what value their manifold air pressure sensor is reading at WOT and high rpm (12-14k). I'm designing our restrictor and would like to know what kind of pressure difference these engines can create after they are choked.

Thanks

You can probably find that information yourself. All you need is an OEM Map sensor and a multimeter. You can calibrate your sensor with a vacuum pump/gauge and hook it up to a closed circuit with your sensor. If you don't have access to one try using a tire pressure gauge. Most MAP sensors are VERY linear.

I would test it myself, our motec displays the value directly, but we broke a spindle on last year's car and don't plan on fixing it any time soon($$$). Since we don't have an engine dyno or a working drivetrain, I have no way to get load on the engine. Thanks,
