Got my new turbo installed finally on sunday. Been taking it easy so far due to lack of head studs but impressed none the less. In DD situations it runs slightly hotter accelerating but runs the same at cruising as my old hybrid H1C. Maybe 50 degrees hotter accelerating if even that. From a dead stop flooring it doesn't lag to bad for how big it is. I think a lot of it is my pump needs tuning and my timing being to the head. Tight TC doesn't help much either I guess. I hit 10 psi around 15mph and 20psi around 20mph. At 25 i'm fully spooled. Probably 25 percent slower spool then the hybrid. H1C ran around 38 lbs and 1700 degrees. Now runs 45 lbs with wastegate disconnected and could only get it up to 1300 on a 0-80 blast. top end is way cooler due to better exhaust flow. Exhaust note is even lower pitched now also. Just running the downpipe. Major drone.

Hopefully get my head studs and new injectors in this weekend and tune it better. Not sure how its going to like towing but so far i likey. Best part of it is that the seals aren't shot so i don't have to smell that stinky oil burning all day now.
