Grounding the throttle body isn't going to make 'more' power overall, but on some cars it seems to make a huge difference in how quickly you can get to what power's there. In my case, the change in low to mid-throttle, mid rpm driving is significant. Perhaps this changed the torque curves a bit through a more open throttle and more fuel earlier in the rev-range? I dunno. Fifth-gear passing on the freeway is now possible (from 60 to 80 is a snap), rather than having to drop a gear or two. Off-the-line acceleration is much brisker and driving casually around town is silky smooth. It feels like someone dropped a v-6 in my 3. I forgot I had the A/C on as well... My car must have been running like a pile of s*** before, never seeming at all happy below 3500-4000rpm. Anyway, I've had a huge smile on my face driving around since this mod.
I've been PM'd about photos, so here goes:
The bits you need. 10gauge 1/4" ring terminals, and 10gauge wire. I just guessed at the amperage though, maybe bigger wire would be safer... After a two-hour commute the wire was barely warm. The throttle body is mounted to a plastic intake, so there's no grounding path other than a small wire in the harness I would suspect.
The path. Pretty simple if you're not too anal about things. The battery-box cover has a slot on the side where the battery-bracket is bolted, just run the wire through there.
The TB. Four 8mm bolts hold the throttle-body to the intake manifold. I used the upper-aft bolt, the lower aft would be more secretive though little harder to get to. Put the bolt back on tight, but don't strip the plastic of the manifold.
The Battery Neg. Run the wire between the ECU box and the battery box, up and around where the bracket bolts. That's a 10mm nut on the battery post. Get it all snug when done.
Enjoy the friskiness.
