hey ken you want to post some pics of your exaust setup on your nytro?

 

[nitro express]

Do you have yours tunnel dumped????

Hey Summitking guess what I"m picking up tommorow????????

 

[Ted Jannetty]

SO what if you turn the exhaust to go WITH the wind and snow in the tunnel??? That whould even help it spool quicker??? NO?? Terry

Still far to turbulant.

Blah blah bla! From what I've seen the exhaust into tunnel works great! This guy doesn't know everything!

Your right Ken I don't know everything.

But I do know this.

Maybe you can explain your theories so everyone can understand them in english, not just it worked for me.

I am always up for an intelligent debate.

Tunnel dump on a sled looking for speed on the flat lands plain does not work beein there done that. As Ted said the snow and air pressure from the track at high speed 100+ mph causes the exhaust to back up. Anything outside the tunnel area is fine but tunnel dumps don't work.

nitro express your a lucky bugger man make sure you post some pics

There are 100's of us out west here who have done this with little or no issues. I hope your new log style header works out for you Ted cause it sure did'nt work out for the okanagon turbo builders here in BC. They scrapped the idea quickly many years ago!

We are talking flatland speeds of 100+ MPH you guys out west don't see that speed going up a hill its a different situation.

Log style header from Ted works awesome over here just as quick of spool as the PL header and way more power with my new turbo!

Hey Ted how about kicking down with some figures. MPH loss? and Torq Loss??? Seems to be the East vs. West debate .... Out West it is way more than just high end speed on a flat. My gut feeling is if I was to race you on a lake you would beat me by a few sled lenghts ( yes probably more) BUT if you were to come hill climbimg / Boondocking out West It would be a much different story ;-)
My opinion is that quiet helps keep our areas open. I for one think this mod is good. Quieter in the parking lot and just a little less of a pain in the ear the rest of the day. Again NO noticeable loss in power, No head ache or ear plugs, more foot room, no sh!# on the tunnel and a hand warmer when you stop. If you are going to dog on a mod then maybe you could back it up with some numbers. in the end If you could prove 10 HP loss I might start to rethink. 5 HP ( you purest will have to forgive me here) will give it up for the benifits. 1 HP, 3 HP really dont care or notice.......

Being a western mountain rider,I like the idea and applaude you for posting and stating your findings.I believe there may be a power loss at top end/hig speed as Ted appears to have quite a bit of knowledge on the subject,however,I am going to try something of this nature to try to queit mine down as well. Thanks for the post as well as the open discussion concerning the affects turbulent air/snow has on exh pulse/backpressure.

Thanks and well said.
I add this for anyone doing a search later on this mod.
Looking back I could have shortened the side distance of the pipe by another inch at least and the diamond plate 1/2 inch but was nervous about building too much heat. but it is running 10-20 deg cooler so I most likely could have done it. next time I would also use plain alumimum and not diamond plate. much easyier to buff and I think it would look better.

I didn't take this as Ted dogging on a mod - I know the subject came up last year and there were guys on the flats that were having the problem Ted describes at speed. Jamie was one of them, can't remember who else, but the threads are there if you want to search.

I think the concensus from last year was that this was more an issue when over ground speeds started getting ovewr 100MPH, so it's less likely this would ever be an issue for you guys out west.

Another example of something that works great in the mountains is letting the turbo breathe behind the windshield. That also kills MPH going WFO on a lake.

Like everything in this sport, your methods (and results) may vary. I agree with you that doing what we can to keep noise down is a good thing. I hope your set-up performs for you as expected, and for your conditions I'm sure it will.

Again where is your technical data?????????????
You obviously have a problem with me and would rather throw stones than have a intelligent conversation and bring real data to the table.

I have guys in the mountains using my manifold and they are Thrilled with the fact that they don't have to worry about cracking and losing a few weeks of riding or worse a fire under the hood.

I for one are all about Quiet I also love this sport and want to keep it going.
If I lived in near any mountains where I could go powder riding I believe I would still have an advantage as far as the sled design goes, but I would need a lighter Rider I am a Large man and this would burry me, He He.

I only offer information that I hope will help you out in one way or another, I am not bashing your design but only hope to help you improve on it with technical information that you can put to use.

There are many variables that make it impossible to nail down a specific figure of loss of power or loss of speed but there is no denying it is real.

Ted.

My new header works great to!!
