Are you referring to the PT71 Billet? If so, Precision doesnt release there compressor maps. Could always check out the new GTX4294R. Its a 70mm Billet turbo from Garrett that flows 95lbs/min i think. They also have a 74mm version that flows around 110lbs/min i think.

Anyone else have an input? pros cons etc.

Ive used the Precision a couple of times, I know lots of people who have run them. The older version was nice, but the newer compressor is even better.

Yea ive read its a 6 blade over a 7. Im wondering if the spool charactoristics are better with billet over cast.

The GTX compressor wheel from Garrett is head and shoulders above anything else right now. Its an 11 blade, primary blade only design. Outflows anything else out there....period.

That sounds like something completely differnt then a journal bearing billet 71 precision

It is different and way better. 1000hp with a 70mm compressor. Beats the hell out of the old pt71.

There is a bunch of compressor maps listed down near the bottom of the page. They dont have precision but they have 70mm and 72mm Turbonetics which should fall pretty close. The turbo should flow enough for close to 850-900hp. There are some guys on supraforums.com that run the billet precision unit with good results. Most there turbo info is in there Dyno Tuning section which you need to be a member to get in there.
