I'm in the process of building my first blown alcohol motor for our 8 second bracket boat. The blower combo came of a similar application to ours; a 555 BBC with a 8-71 blower. Although the manifold has space for one, it doesn't have a burst panel or other pressure relief. The guy I got the stuff from said he got away without one, but thought it best I add one. So, is a burst panel necessary. I've also seen the spring loaded pressure relief style as well. Is one style preferable over another.
