I tested the car in track racing and did pretty good, very reliable and stable, I would say for endurance races probably those engines will last forever. BTW has anyone taken the red M103 turbotechnichs kit to a Dino to test HP and torque, turbocharging a 6cyl its always been in my mind. Regards

My circa 1991 TurboTechnics kit installed on a M103-12V with stock compression and internals has been dyno'd numerous times.
The enrichment control is via a Split Second additional injector controller that fires the two additional injectors that are located above the throttle body in the air valve assembly. The AFR's were programmed on a dyno with 11.7AFR at .5 bar boost.
The dyno pulls were made on a Mustang load dyno which reads about 15% lower then the more common inertia type dyno. The load dyno gives a more real world reading as load/resistance is applied to the driving wheels much like what must be overcome on the street.
Dyno numbers are purely analytical and best used for comparison of before and after equipment change and tune.
1988 M103-12V USA catalytic converter version.
HP / Torque
Published 177 HP / 188 FTLB
Stock RWP dyno 135 HP / 145 FTLB
Turbo RWP dyno 262 HP / 302 FTLB
The real number you look at is power increase.
262/135 = 94% RWP increase
302/145 = 108% Torque increase.
Extrapolate to crank power using published ratings.
HP 1.94 x 177 = 344
Torque 2.08 x 188 = 391
Boost is set at .5 bar and KE-Jetronic is stock and set to factory specification.
