I'm going to get a BBK 70mm throttle body this week. So what kind of gains am I going to get out of it?
-I have Cat dual exhuast-cold air intake- 4.10 gears- When I'm done, I'm getting a Diablo chip.
Thanks to all my freinds @ AFM

i don't know what size the stock tb is, but i think you're gonna HAVE to get a chip when you install the new tb. i've read in other places that a tb makes a noticable difference only when you have a tc, sc or nitrous.

You can expect to lose about 2 hp. A 70mm throttle body is WAY too big for a bolt on 3.8. To put this in perspective, a GT has a 65mm throttle body and it requires much more airflow than your 3.8. Spend that $300 on underdrive pullies or a ported upper intake manifold.

So what are you calling poweradding??

he means a blower, nitrous, turbo. The big guns that add lots of HP and require LOTS of airflow.
