Default I think this is the ultimate powerband setup for track..580BHP/600ftlb

We just got the dyno testing done on our 2002 WRX.

old setup:
Full-Race twin scroll GT3582R 1.06 A/R
garageGT spec EJ257 shortblock
DPR EJ257 heads w/Tomei custom cams
MPtuning AEM EMS
550BHP @ 22psi
GrupN 1-4 dogbox / Cusco tarmac gear / Cusco LSDs
Carbonetic twin plate carbon clutch

We only changed the exhaust manifold to a Tomei unEqual lenght single scroll manifold, we swapped the turbo hotside to the new Tial V-band 0.63 A/R housing. Nothing else was changed. We achieved an incredible bottom end with this new housing, dyno charts are below. The torque gain at the wheels was 126 ftlb @ 4300 RPMs. Also peak torque was pulled back to 4300RPMs from 5600RPMs peak for the old setup. Turbo spool is 1000RPMs sooner with better peak HP ! very unusual but impressive ! This is a torque monster, very promising for upcoming races..This kit will be in production soon, stay tuned..

Final output:
441WHP/456ftlb torque @ 22psi (MS109)
~ 580BHP/84kgm torque @ 1.5bar (MS109)
