Update to the dyno chart I posted awhile ago of a friend/customer's car. We put on a new set of headers and modified them to be twin scroll. We also threw on a smaller exhaust housing, and took out the EMS and went to a Cobb AP. We went to the dyno on pump gas, and did much better compared to the old setup.

Car: 05 STI
Facility: R/T Tuning
Type of Dyno: Mustang
Boost: 25psi
Fuel: 93 octane
Altitude: ~360'
Peak HP: 521whp
Peak Torque: 486wtq

Built by Satoru Speed and Fabrication
Tuned by Andy at R/T Tuning

Built engine/heads
Custom Twin Scroll FP35R turbo kit Built by Satoru in house
ID 2000's
Bosch 044
Custom downpipe/dump tubes
Wire tuck

The red is the new setup, blue is the old setup, and green is a typical stage 2 STi. We seemed to have finally found the sweet spot, getting the 35R to spool up quick and make a ton or torque down low for a larger turbo. We may go back for Race gas number later this spring.
