Not sure, but I think there was something that was too big on the 71...not sure though.
Is the Billet HPQ-70 or 71 available? Don't they have to be available to everyone by a certain date to be legal for the season?

Anyone, know where the turbo rings are?
Yep... with the plug.
The billet 70MM compressor wheel measures 70.5mm (inducer) and 102.5mm (exducer). So far we like the results we have seen. As far as the rules, we have that covered. :wink:
Tony, I hear there will be good deals on popcorn at tech with proceeds going to payouts.

So, if there is some type of new turbo, and the general public does not have access to it....it would be illegal? Right?

Hmmm... Harry has publically stated the billet 71 is illegal for TSM. :wink:
