Well first, looks like dropping the trans to see why the clutch got hinky last night on my way home from a local meet. On engine braking and just before throttle tip-in, I was feeling quite a bit of chatter from the flywheel to flexplate. Not sure why, but I have a good suspicion that bolts are backing out. As much as I love the holding power of the Clutchmasters FX600 twin disc, it has always made a lot of noise. Also I have had issues with the aluminum flyhwheel threads anytime I have had to r&r the clutch assembly.

So.... look into what it costs to rebuild the clutch, or possible downgrade to an FX400 or FX500 single disc.

But besides that: 1000cc injectors, water injection (not for the methanol octane boost, but to control charge temps), and a new manifold to replace the log.
