Measuring Pressure/temp Techniques

[Harey]

Hi,

I am in the process of troubleshooting/fine tuning my setup. I am wondering how people measure pressure/temp drops across intercoolers, intake restrictions, exhaust backpressure, manifold pressure etc.

What tools do you use? How did you fit them?

Any help much appreciated!

ive got a datalogger serial port 4 temp sensor logger from an australian company

they build it and send it out to you

its fairly cheap

K145 - Temperature Logger Price Photo Docs

This kit is a 4 channel temperature meter. The temperature data, in degrees C or F, is output as a continuous data stream over an RS232 serial port. The kit uses a PIC12C509 and up to 4 x DS1820 digital thermometers (only 1 supplied - more available on request). No external power is required (the kit is powered from the serial port).The output data is in simple text format. Simply capture the data to a text file and then import it into Excel to produce tables and charts of temperature readings over time. Or you can write your own BASIC programs to grab the readings.This is an ideal use for old 386 and 486 computers - continuous temperature data logging. As you can see from the photo there is not much to the hardware.

software exists for windows or linux

im using it to temperaure log inside and outside temp and then into linux for rrd/mrtg

i never got around to use it for car

but wanted to do in and out temps of the intercooler core

but never got around to it

BCNR33/BNR32/BNR34 airtemp sensor is same as water temp sensor, the same physical part

so you can always get one of those and do a bung in the intercooler end tanks and do it that way

no idea on voltage mapping to temp but i cant be too hard to work out
