Boost Gauge How to fit a BG |

|
No |
One of the first items to install before any other modifications |
Exhaust Gas Temperature |
|
|
ish |
The turbo will need to come off in order to drill and tap into the exhaust manifold. Best place for the sensor is either No2 or No3 exhaust runner as these two run the hottest. Do not place in the downpipe as this is far too far away from the action! On the 205WRC the sensor can be located in one of the bolts in the exhaust manifold Increasing the fuelling will reduce EGTs |
Air inlet temperature Article |
|
ish |
May need to drill and tap the intake manifold in order to place the sensor directly in the airflow and get good accurate readings | |
Oil pressure |
|
|
ish |
GReddy provide an adaptor plate that simply attaches to the oil filter housing. Comes complete with 2 sensor holes in the mounting plate. Fits fine on the 205, would probably be ok on the 165/185, but if a DP is fitted, this may be a problem.
Adaptor plate Part No 12002801, comes with 2x 1/8NPT and 1x M12 holes for gauges It is quite surprising to see how just a couple of hundred rpm will affect the pressure at idle... |
Oil temperature |
|
|
ish |
If the oil temperature gets too high then the oil may break down and get too thin. If the oil breaks down then it's lubrication qualities suffer and it'll be an expensive repair job |
