Title: How hot is your exhaust?
Post by: Ricco_04 on August 27, 2006, 12:45:41 PM
When my car has warmed up and is idling the EGT out the back box seems really hot.  I thought it was origionally down to having 2 cat\'s but these have now been removed and little or no change.

If I put my hand about a foot from the tailpipe then I can hardly keep it there for how hot it is :3Confused  I also had a look at a mates car and his seemed only slightly warm in comparison :xconfused

Is this normal? (thinking not!)
What are everyone else\'s like in the same situation?
What could be causing it?

Many thank\'s, Ricco. :3Confused

For me it is a toss up between whether I pass out from the pain of the heat or I get asphyxicated from the fumes.

:Giggle  Thanks :D

Well i\'m asking because when I was at Pod I couldn\'t tell if this MR2 was running, so I put my hand by the exhaust and I could feel it but there was hardly any heat - which is what led me to try it on another rex (which was a little hot but still much colder than mine)  

Asked a mate and even he neally burnt himself cause he didn\'t expect it!! :evillaugh :evillaugh

Remember if its the MR2 from 1993 - 1998 there are 2 exhausts but only i really kicks stuff out the one on the left is the working one, left hand side if stood at rear of car.

I had a MR2 hence the remark, mine did this anyway :Laugh

My understanding is the rotary engine does run very hot and hence is expelling hotter exhaust gases that a piston engine. Wouldn\'t want to hold my hand anywhere near the exhaust on mine either.

Lol I know what you mean, saw it on a mates MR2 one on a cold day and could see the moisture coming out of just the one. Luckily for me this other one was just a single exhaust (the MR2 with Celica headlights BTW) else I would have just been confused all day! :Giggle

Well I guess it all helps spool those tubbies up quicker! :D :driving
