I'm going to put up some of my subaru setups we have built/ worked on and the results we have got along with the issues/characteristics of setups to try and let people know what works and doesn't along with power results in the end.
Note: all corrections factors are always 1.00 as my belief is anything else is just a ego booster.
Some of these cars are flex fuel and you will get to see the advantage of ethanol over petrol.
Will upload more when I have a spa
Big fan of this vehicle. It's a tidy gc8 with v7 drive train. Mods being simple for power. Forged 2l motor with standard v7 sti heads. Sti twin scroll with vf36. Factory v7 sti top mount and g4 running the show with flex fuel to e85. Id1000 injectors which are maxed out with a dw200 pump. Custom built SAS intake and exhaust.
