Thanks Title: Re: Muffler temp ? Post by: Tony M on March 23, 2009, 20:52:38 pm Higher than the gun goes
Title: Re: Muffler temp ? Post by: Brown-nose on March 23, 2009, 22:58:39 pm Higher than the gun goes hotter than 400 C (750 F) ??? Title: Re: Muffler temp ? Post by: Neil Davies on March 24, 2009, 10:05:31 am I know that they're hot enough to burn your leg and leave a nice patch of skin on the muffler... :o
Title: Re: Muffler temp ? Post by: Brown-nose on March 24, 2009, 10:19:08 am I see Eastwoods do header paint that goes up to 650 C but muffler paint (not for headers,manifolds etc) that withstands up to 150 C
I'm not planning on using either of those but do you guys think those figures are accurate ? Title: Re: Muffler temp ? Post by: Hotrodvw on March 25, 2009, 06:13:24 am Higher than the gun goes On the muffler or the head pipe? I can see the head pipe being up there....... Title: Re: Muffler temp ?

Post by: Tony M on March 26, 2009, 22:14:21 pm At the head pipe over 600 deg - at the muffler it will depend on if your at idle or at speed - 350-400 at idle - after running for some time - and hot ,hot,hot when under full throttle

Post by: Brown-nose on March 30, 2009, 16:52:55 pm so i borrowed an IR gun today. after 30 mins at 70 mph + i stopped and took some readings. then i went for a long (45 min) slow drive at 40-50 mph with some traffic stops and some idling. the header (1 3/4 stainless) temp was 200-250 C max and the muffler a bit below that. the hottest part of the muffler was the flange. even the pipe into the muffler box was 200 C or under
this was just pulling over and reading it with the car idling. |
