June 9, 200620 yr #1 hi just a quick question. what's the importance of monitoring oil pressure, as opposed to oil temperature. also what is the normal operating pressure that you guys are getting, as I am getting a boost/vac and oil pressure gauge installed next week. thanks
June 9, 200620 yr #2 Why get one if you have no use for it? The oil pressure is used in racing applications so at a glance you can see that you havent dropped or burnt any oil and have good flow through the system. On the road I can't see a use as you have a warning light on the dash if anything goes wrong. In fact the car will probably hit limp mode before you even see a drop on your gauge. I would go for a temp gauge or something.. maybe even an O2 mixture gauge
June 9, 200620 yr #5 Get an oil temp gauge..... Push your T hard and you'll be surprised how hot that oil gets... especially in summer.It's also a good idea to wait till the oil temp rises before pushing the motor hard.Water temp gauge is NOT indicative of engine oil temp, which is much more important for lubrication. If viscosity is too high (cold oil) then oil does flow properly. Also when oil is cold, and you push the motor hard, the oil pressure rises quite high and can blow oil seals. Certainly is a problem with older cars, anyway.Like I said, get an oil temp gauge, with electric sender unit.Then if you are really keen, get a second sender unit and fit it to your trans oil line to the oil cooler. Use a relay operated by a dash switch to switchover from monitoring engine oil temp and trans oil temp. tom
June 9, 200620 yr #6 get oil temp, it will be of more use, or if you just want show get an AFR as it has pretty lights.....
June 9, 200620 yr #7 Yep an oil temp guage is the way to go - but gee whiz the idea of those pretty lights in an AF meter have got me thinking ...
June 9, 200620 yr #8 I have just bought an AFR guage and wondering what exactly they tell you and how you can use it to monitor the car
June 9, 200620 yr #9 I have just bought an AFR guage and wondering what exactly they tell you and how you can use it to monitor the car←when you find out, let us all know.sorry, that's a bit harsh on a newbie....AFR gauges are useful to provide feedback on how lean/rich your fuel mixture is.Power can be substantially increased by leaning the mixture off, up to a point, before excessive heat causes detonation and eventual engine failure.Running richer mixtures, safeguards against that possibility, but saps peak power and also consumes more fuel. When the car is dyno tuned, the tuner uses a good quality wide bandwidth lambda (AFR) sensor in the exhaust pipe, which provides accurate indication of the ratio of air to fuel in the mixture.The problem is, the AFR gauges sold to fit into the gauge pods for a cost-effective price, have narrow bandwidth sensors, and so provide very little useful info.When you floor it, it will show rich, when you back off, it will show lean.Just leds flashing on and off as the sensor signal output crosses the thresholds set for indicating rich or lean. These gauges don't have the resolution to provide the useful info of exactly what the ratio is.... just my opinion.tom
