So long as you keep them under compression, they are as reliable as steel. The only time I had problems with aluminum rods is when I de; /html/land-speed/2003-06/msg00311.html (9,295 bytes)

Aluminum will also offer a small amount of "give" (in compression) to cushion added cylinder pressure from turbo or supercharger. __________________________________ Yahoo!; /html/land-speed/2003-06/msg00315.html (8,611 bytes)

You do set your engine up accordingly, right? Since RPM stretch does occur, manufacturers suggest a conservative range of cycles before replacement is necessary; /html/land-speed/2003-06/msg00318.html (8,854 bytes)
