Bellhousing

[JohnRoderick]

I assume you are drilling a hole through the liner too. If so, are you worried about compromising the integrity of the liner?

Are you also saying that other than RT, the air gap does not impact performance at launch? So RT aside, there is no difference between launching with 0.030" and 0.060" air gap?

As you are mainly looking for the minimum air gap, I have a round rod (that is the minimum gap diameter) that fits through the hole easier, I ground it to a point at the end so it will slide into position easier. Bear in mind that if you are shifting without the clutch (which pretty much everyone is) that air gap is not that big of a deal, mainly I use it as a delay box for fine tuning reaction time.
