Mass Air Flow Sensor 1985 911 3.2
Anyone has any experience of fitting a Mass Airflow Sensor. There have been many claims of the benefits of taking out the barn door sensor, but Huntly Racing seem to quote the biggest improvements. I enclose the URL to check it out. http://www.huntleyracing.com/massairflow.htm
I look forward to your thoughts/experiences. Peter |

Don't waste your time or money, unless you want to have the
DME re-designed. A properly setup AFM and DME can't be improved on easily by adding a MAS with significant results. Have Fun Loren '88 3.2

There is a company in Europe called "Sportwagen Systems" they take a 3.2L Euro car with no catalytic converter, add a cat, add a genuine Porsche "hotwire" maf, change to larger injectors, and reprogram the DME for the changes and end up with 257hp as opposed to the stock Euro 231, and that is with adding a cat where there previously was none.

Here's more info
It is just over the French/German border, but on the German side. Sportwagen Service Industriestrasse 6683 Spiesen-Elversgerg, Germany Tel 06821-78414 From the Aug 2000 of 911 & Porsche World Retro-fit cat to pre-cat 3.2L and Turbo cars (Euro) SWS process is three parts "The restrictive factory air-mass sensor is replaced with the hot-wire sensor from the 993.... Then the catalytic converter is fitted and the exhaust modified to take the lambda sensor. Bigger injectors are fitted because the standard items are right on the limit.... Finally, the Bosch ECU is remapped to take the new parameters into account. The result is 258bhp..." (this is all on a Euro car with 10.3:1 comp and 231 stock hp.
