ZZZero Posted March 25, 2006 Share Posted March 25, 2006 I just purchased a boost guage for my 300zx and need to know if the fitting can be after the throttle body? There is already a fitting with a plug in it right after the TB and i'd rather not drill a new hole.ty Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted March 25, 2006 Share Posted March 25, 2006 Yes. You want it there otherwise you won't see the correct vacuum reading. If it is a vacuum/boost gauge. Also, you won't get the correct boost reading at part throttle. Although, I've been tempted to put an extra one before the TB too see the surge after you close the throttle.
