Exhaust Header Temp.

[cusso ken]

Just to put things into prospective the turbo inlet pyrometer on our Mack Diesel would often raise to 1200degrees I have seen 1320 degrees pulling up the Toowoomba range now that is HOT!

Exhaust pipes are hot?

AND you need heat shields on all the sytems .

without going through 8 pages of this thread, can i wrap the exhaust pipes with cloth tape and then refit the stock chrome shield? or is there a 3rd party vendor that sells other chrome heat shields?

i'd really like to decrease the engines heat on the block side of the engine without doing any fancy electronic/computer re-mapping for enriching the engine a bit!

Not cloth....well strictly speaking the pipe wraps are a kind of cloth, but it's more like rock wool or something heat tolerant.

I think if you wrap it just right you may be able to refit the heat shields. You may need screws a little bit longer, and I would use stainless steel if you find that to be true.

i'm sorry i used the word "cloth" in the general sense.

i used DEI's Titanium Exhaust wrap on my Bobber's down pipes and it worked out great! was just wondering if anyone using this same stuff (or a similar product) had fit it under the chrome shielding?

Before I had the CES headers I had a set of Sam's Thug headers they were Stainless and Ceramic coated with twin layer Heat shields Sam only supplied the heat shield for the Thug header and the Predators because the pipes were mainly straight and even he said that making the heat shield were a pain in the arse to make so I can understand these other system makers not wanting to make them as as the heat shield would cause a Dramatic rise in Price .... would you be prepared to pay an extra $500 + (only a guess as they would be very much time consuming to make them follow the lines of the headers.

Do these look familiar Hans?

One of the reasons I like these headers so much is because of the amount of work that has gone into the shields - making them almost look like they could be factory pipes. As you can see making the shields for this system would have been very time consuming indeed. I still owe you a beer or two regarding these mate.

I think the best solution for the OP would be to finish off any other engine related mods which he may want to do, use a Hanso tune to run safely until he can get to a good dyno operator for a proper tune. I know the tune Hanso gave me was very safe (in reference to lean/rich - rich being safe). If it were me I would make sure I have a new fuel filter installed and a full tank of the fuel I USUALLY run - nothing exotic before heading to the tuner. No point tuning your engine on a fuel you never use or have trouble accessing.

I find it hard to see any positive gain exhaust heat or otherwise in switching to a low octane fuel. There will be negligible difference in exhaust temp on any given standard machine going from say 98 to 95 with no other changes. Certainly not the difference between a leg which is well done to a leg which is medium rare. The reason we use higher octanes is not generally heat related but it's resistance to pinging which allows us to do lots of fun things like cram more air (and fuel) in, and increase the timing. Of course alcohol is a different matter but doesn't really apply here.

I have found, as I'm sure many of us have is that one of the best value for dollar for mods is a good dyno tune. Not only in the peak figures but in the delivery. Even on something just rolled off the showroom floor, if I recall correctly there is a thread on here somewhere where Neville had great gains on a dead stock brand new Rocket.

Super D if you get your bike tuned you at least remove that variable possibly solving your issue, and get an almost guaranteed performance increase as well. Aside from that well, the heat is just normal and you may need to shield yourself.

They Look Awesome Luke Ol' Mate you did them proud but having seen your collection I knew you would Hows the Vet business going

Thanks mate, they were exactly what I was after. Business is good! Really enjoying the change and constantly learning something new. Make sure you drop in next time you're up our way

I kinda scanned through this whole thread, and thought I'd add. The first time I ran my 2005 basket case with no heat shields, it was so hot I thought I had exhaust leaks. Put the shields on, and all is well. These engines do get hot, even with everything correct.

Just a little story:

I left the key on, the battery drained a little. I still got it started and on the way home I stopped at a Taco Bell drive thru. They took a long time to get my order, so by the time I pulled away, the temp light was on and the motor died. I barely got it cranked again and hit the road. The engine cooled right away.
So when i checked the temperature setting for the fan to come on, it was high. I reset it to the minimum which is around 200oF.
Now when i ride it seems to keep the radiator cooler which seems to make the bike a little cooler at stop lights. Now it might be my imagination but might be worth a try.
Good story?
