Boost measuring point - opinions? (3.3 TD)
Posted: Mon Aug 16, 2004 9:23 am
Today i moved the line to the boost gauge from the turbo-to-wastegate line and up to the point where the pressure valve was located before. Got the parts from a plumber, just a matter of replacing the blind plug (pressure valve removed earlier) with a plug drilled and threaded for the fitting to the gauge line.
In my opinion the boost should be measured here, close to the engine, to give a realistic measurement of what boost actually reaches the engine.
It actually reads slightly more here than at the line between the turbo and the wastegate!
Next: Should i also attach the wastegate line to this point? That way i think the turbo would automatically compensate for any loss or gain in the tubes between the turbo and the intake, even if fitting an intercooler with tubes.....
Anyone having thoughts or experience about this?...
