t78 single turbo dynoed at 328whp (details inside )
originally the car had stock twins which weren't operating properly because of the control system and the stock DP that was on the car had failed so the car was in need of some maintanace. it seemed that it had 120whp or so before any work was done
. the owner decided to upgrade as well as do the maintance at the same time, bought a used t78 kit which turns out to be voskos old kit, it included the turbine, the dp, wastegate and the turbo manifold. after puttign the car together and tuning the car on the street i took the car to the dyno to do any of the fine tune adjustments and to see what power it would put down. the car was running off the wastegate spring which is 9-10 psi
owner: Francisco Vega (paco)
relevant mods:
stock port reman
t78
apexi PFC
3 inch exhaust
greddy 3 row
stock ignition with 9s all around

Why run a t78 at 9psi? They dont even begin to wake up until 15psi/400rwhp. Stock sequential twins could have accomplished 328 at the wheels pretty easily at 15psi.
