TC78 stock bottom build thread
So theres been a few changes to the car over the last few weeks. We went back to dyno on three more pounds and only got to 628/638. This was telling me that we were basically out of turbine, i couldnt imagine what the BP was, never measured it, but from the sounds coming out of the gate there was plenty of pressure there. To keep from having to upgrade, then upgrade again i actually found a mustang guy looking to downsize turbochargers. I wound up swapping my 78/68 for a billet wheel s480/t4 1.25 piece with an 87mm turbine. SCORE!
While the car was down i also went ahead and replaced the cam and valvesprings. Cam wound up 23x/23x 600/600 114+3 and i used a set of pac 660s to keep everything stable along with ti retainers and moly pushrods.
Im not sure what shes making now but i can tell its quite a bit more and there is no choking off at 5600 like before, she likes to sing now! Ill update more once we get back on a set of rollers.
I dont have a legible timeslip anymore...sorry
