N/a Tb
#1
Anyone with a 2nd gen N/A try this: when the car is off, push the primary throttle all the way around until it stops, then reach up and push on the secondary throttle. On every TB I've seen, the secondaries will move a little farther. That little bit makes them come all the way open, normally they are just short of open. Do you think correcting this would give me more power? Or does it even need to be corrected? I want to know if this is normal, or if it's a problem.
Oh and by the way, what do you do when you can't do the TB mod because those screws are stuck? I tried, but just stripped the screws, and I was using a slotted one too.

this is engineered into the stock throttle bodies, if you check the shop manual the explain how to adjust that offset. It's purpose is not exactly known to me but they intenetionally make the secondaries open a little 'behind' the primary. It might be because if you bend the tab that adjusts it so they open fully, at the idle position the secondaries are open a little which will probably make your idle too high.... the linkage isnt quite right.
BTW, good question... I'm curious what others have to say about that one too.

couldn't they have designed the cam so they opened a little behind, but opened fully at WOT? Do you think "fixing" this would yield any performance?
