M1 1600cc Normally Aspirated
it had a JR CAT back, 2" CAT replacement pipe, K&N air filter with 14 degrees timing.
Peak power 122bhp, peak torque 110lb/ft at the flywheel

As above but with AVO Turbo and MoTeC M4 Pro at 0.5 (7.25 psi) BAR Boost
This is after we added our AVO Turbo kit with 320bhp turbo. The same JR exhaust and CAT replacement pipe was used.
Peak power 199bhp, peak torque 179lb/ft at the flywheel

AVO Turbo kit and MoTeC M4 Pro at 0.4 (5.8 psi) BAR Boost
Back on the dyno we changed the exhaust to a turbo exhaust and added a 2.5" CAT replacement pipe. The exhaust has little back pressure and we made adjustments to the previously conservative timing curve. Intake temperatures were around 12-15 degrees Centigrade. No boost control valve was used.
Peak power 209bhp, peak torque 183lb/ft at the flywheel

AVO Turbo kit and MoTeC M4 Pro at 0.6 (8.7 psi) BAR Boost
As above but with more boost!
