I found the link to this study on a Lincoln Town Car forum:
Air Filter Comparison Study While it was done using air filters for a GM Truck, the conclusions are interesting: 1. choosing a filter type or style for ‘more flow’ for either performance or fuel mileage is useless, as they all flow about the same 2. there is a wide variance in the ability to filter contaminants; the best was an unoiled synthetic fiber passing less than 1% of the contaminants introduced, while the worst was an oiled foam allowing 40% to pass. To bring in some 914 relevance, the K&N was second-worst, passing 35%. I make no claim that this applies directly to our 914s, but I found it interesting since I've always used K&N filters on my performance cars. |

Is this an originality thing? Most don't run rear sways, not even the AXers. Always learning. Rand, I think a rear bar is a personal preference thing. I've been autocrossing 914's for 35 years. 1,600 lb four bangers and currently a 914/6 conversion with 3.2ltr and I've always successfully run a rear bar in order to get the car balanced and get good turn with excellent corner exit. I'm sure lots of folks have gone without a rear bar but don't dismiss them. Thanks Bobby, I appreciate the input. |
