In Reply To	How is it so many other turbo cars have tubular manifolds posted by Jayru on May 10, 2012 at 06:54 AM
Message	Inconel tube has to be very thin to be able to bend it, the short manifolds used on a Z with thin Inconel tube simply run too hot. Inconel is much better than 304 or 321 stainless in the same thickness, but any material is only good for so many heat cycles at a given temperature. Most turbo appications that run tube manifolds use longer runners and thicker tube. To understand what Inconel Manifolds go through on a Z with these short thin manifolds, watch this video.

(n/m) - BlackholeZ 01:53:07 05/11/12 Its not the inconel that cracks on the manifolds.. - KongZTT GT28RS MD 14:06:39 05/11/12 There is much more to it than the name of the material. - zellamay 21:36:24 05/09/12 The flanges are not inconel.. they are SS - KongZTT GT28RS MD 01:43:04 05/10/12 Well the RZT mani's where not inconnel but something - MikeVar82 21:11:55 05/09/12 I'm gonna call it a day and buy MS manifolds (n/m) - NextZ 21:55:17 05/09/12 This is the correct answer (n/m) - BigTDogg (MA) 08:44:17 05/10/12 i thought all tubular manifolds cracked... - Shiers69 21:56:32 05/09/12 How is it so many other turbo cars have tubular manifolds - Jayru 06:54:48 05/10/12 I'd have to speculate it has to do with the cramped engine - BigTDogg (MA) 08:45:51 05/10/12 Z turbos are tiny compared to other cars using tubulars. - dogpile 08:58:09 05/10/12 Even with stockers... - BigTDogg (MA) 09:27:42 05/10/12 That's a good 3' sooner than mine. - dogpile 09:41:22 05/10/12 Bracing would be a good thing if the same material - BigTDogg (MA) 09:56:53 05/10/12 I just used rod ends and a threaded rod. - dogpile 10:27:27 05/10/12 Video - Greg D. (Specialty-Z) 14:39:44 05/10/12 A properly designed & made tubular manifold will not crack. (n/m) - induetime 16:45:55 05/10/12 They have problems as well. - BlackholeZ 01:51:46 05/11/12
