(Matt Dralle) ________________________________ Message 1 _____________________________________ Time: 08:42:51 PM PST US From: Matt Dralle Subject: RV8-List: Std vs. Aerobatic Engine Vibration Mounts... There was some discussion a while back regarding the Standard engine vibration mounts verses the Aerobatic style. I happen to have a set of each and thought others might be interested in seeing what the physical differences actually are. You can see from the pictures, that one half is exactly the same. It is very hard and appears to have a "washer" of some sort molded into the rubber about halfway. The rubber is very hard. It carries the part number "VIP50901-78". The other side, however, is different between the two types. On the Aerobatic style, the other side is simply just another one of the first side. It has the washer inside and appears to carry the exact same part number as a matter of fact (VIP50901-78). On the Standard mounts, however, the other mount is signifificantly different and carries a different part number (VIP50900-71). As you can see from the picture, it is taller by about 25%, it doesn't have the internal washer, and the rubber seems to be a lot softer. On the softness of the rubber, it might just be that it feels that way because there is more of it without any objects molded into it. But I think it does feel a little softer. The long bushing is also a bit longer on the Standard version. What does it all really mean? I don't know, but the aerobatic ones seem more manly, so that's what I'm going to go with... ;-) And, furthermore, I like my engines mounted like I like breasts on woman - firm, baby, FIRM! :-) Matt Dralle RV-8 #82880 N998RV http://www.mykitlog.com/dralle ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv8-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV8-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rv8-list Browse Digests http://www.matronics.com/digest/rv8-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
