boxpin Posted August 3, 2011 Report Share Posted August 3, 2011 I am noticing with the N/A throttle body that when I let off the gas right at the point where the butterfly is closed there is an abrupt shut down of the engine or deceleration where it goes negative instead of a positive force. I dont know if I am explaining this right. Its either go or no go with nothing smooth in between. I think this is what the plastic puck if for on the butterfly. Is anyone running a straight N/A body without the 960 butterfly, meaning your using the puck? Just wondering if the transition is smoother. Seems like moving to a 3" opening from a 2 1/2" that the puck in place would still net you gain. Link to comment Share on other sites More sharing options...
Zappo Posted August 3, 2011 Report Share Posted August 3, 2011 I have the same issue on mine. I wasn't sure what was causing it. Link to comment Share on other sites More sharing options...
nocturnal7x Posted August 3, 2011 Report Share Posted August 3, 2011 hmm, Im running the NA throttle body with the 960 plate, and I have not noticed anything strange like that. The car felt a little weird when I first installed it, I had to get used to it and the car probably did too. But im auto, could be something you manual guys only would notice.

Zappo Posted August 3, 2011 Report Share Posted August 3, 2011 Yeah, I don't think it has the same issue on automatics because they hold the RPMs longer. Link to comment Share on other sites More sharing options...
Volvo5.0 Posted August 3, 2011 Report Share Posted August 3, 2011 You really don't want the throttle plate COMPLETELY closed at idle. Usually about 1/4 turn on the set screw is enough to give a small air gap. If you have the t-body off the car, hold it up towards a light. Should see a little daylight all the way around.

oldduttyvolvo Posted August 4, 2011 Report Share Posted August 4, 2011 Make sure your basic throttle setting is correct. Loosen throttle setting adjustment screw lock nut, and turn adjustment screw until it just touches the throttle lever. Then turn in an additional 1/2 turn.

JDMS60R Posted August 4, 2011 Report Share Posted August 4, 2011 Mine does a wierd idle/afr dance as I push in the clutch, goes real fat then instantly lean for about 3 seconds like 20-1 afr lean. I'm running the na without a plastic piece. Maybe I will switch back after work to the turbo piece and report back. Link to comment Share on other sites More sharing options...
