Now what we have seen thus far is Stage I and II turbo setups on the stock DME from Max PSI on the E46 M3. In Stage II trim the car has shown an impressive 697 wheel horsepower on MS109 race gas. They also are already in the 10's in the 1/4 mile with the with the car. Now I was sure to ask about the timeslip and if they planned to hit the strip again as it looked like past the 1/8 mile the car had some issues killing the top end. I was told the car was pulling timing and they would be heading back out as soon as it was possible. So expect to see more timeslips from the Stage II setup soon.
Now, what I was pleased to learn was that Stage III and Stage IV built motor setups are next on the agenda. 697 wheel on the stock motor is with MS109 and they plan to match that output with the Stage III on pump gas meaning 700 whp all the time. The Stage IV setup will go beyond that with race gas and E85 maps. What that puts down we will just have to wait and see .
