Anybody running the new "Skunk 68mm TB" yet?
well I was told today from someone who spoke with skunk2 that there is no recall but then again I was also told that the recall entailed something about the paint on it making the butterfly stick. I would triple check just to be sure.
I bought one and attempted to dyno test it...it was the biggest pile of crap ever. I looked nice, no doubt about that, but functionality-wise it was awful. The first issue we encountered was the TPS sensor not fitting; talked to Skunk2 and they blamed their manufacturer and sent some adapter spacer thing. Next, with that adapter installed (as a side note, the little TPS bolts included wouldn't thread all the way in so we had to tap the hole deeper), we did a boost leak test (never got above 2psi on the tester) and air was pouring out from around the TPS...Skunk2 didn't use a shaft seal, just a bearing! Next, after slathering the TPS with RTV so it would seal we did another boost leak and now the other side where they supposedly did use a seal was leaking really badly too at less than 5psi! We decided to dyno test it anyway to see what this thing could do. We did port the IM inlet to 68mm. Start the car and it would barely run; great. We then confirmed the TPS was set to spec; Skunk2 provides one spec but its not correct according to Mitsu, eitherway, we tried Skunk2's spec and Mitsu's OEM spec; car still idled like crap. We adjusted the BISS to no avail. In the end, we could never get the car to make a clean pull due to issues from this billet paperweight. A few days later I installed a Mil.Spec 65mm ported throttle body and the car idled and ran perfecly with zero boost leaks. After much argument and denial that the product was faulty Skunk2 finally issued a refund for it.

That is a bummer to hear as i had posted a question about how much psi they could hold when they were first posted here.
Someone then said they should easily hold 40+ psi but i guess not.
Seems like the mil.spec tb's are the best for oem flanged i/m's and luckily we have had great success with our TB's up to 50psi but they are for a different style flanged i/m.
