APR S4 Stage 3 Dyno results!
We dynoed a customers APR stage 3 S4 on 100 octane on Friday. The car had the full stage 3 kit and made 307 wheel horsepower on our Dyno Dynamics dyno. The car was running 22 psi and a 12.5:1 A/F with the 100 octane map. Very impressive car and what I would expect a 400 hp car should make on our dyno. The customer was very happy with his dyno results. We also dynoed an E46 M3 which made 247 wheel horsepower, which seemed a little low? Have a great weekend guys.
