The graphs shown are for a 500 with Wirges (1 cylinder) What would be the affect of increasing the belly diameter? If you wouldn't mind...lol just curious

Having easy and quick access to the pipes in storage.Just for kicks I went and checked the pipes out.Measuring the silenced Wirges 500 I get 9.5".The Stinger 750 Dencos measure 6 3/4". The Stinger Wirges 500 pipes measure only 5 1/2" ? I measured a set of Denco H1 500 Silenced chambers and they are 6 5/8 ".When I cut open the silenced Wirges and remove the baffles and modify them, I will probably use that as a base line.

It's always better to cut "gradually" and try it ? Than to cut too much off ? Much easier to reconfigure by cutting than cutting too much and having to add back on ? All time consuming and who has that much spare time LOL !!

I've been following here with interest. I have a few Wirges h1/h2 sets as well. I'm considering hacking up a set just for the fun of it too! 5 1/2" centre section and gutted silencers... might be a hoot on Seaglider's FBG/Tracy Project. We have a set of Denco's, as well as a WTF 'cone set' too. We like options.

Silencers do act like stingers. Essentially they are stingers. Yes, the pipe design includes the resistance to flow provided by the stinger, and in fact relies on that resistance to work.

Yup carpenter "measures" and "knows" what measurement to cut the piece and double checks it,that always works best.Working with V8 engines and headers.In theory the shorter the header tubes into the collector, makes more torque, and the longer tubes makes more HP.Tuner has to experiement or find the correct length for the combo or what the happy medium is ? And when opening up the headers the power and torque drops off until you put a torque tube on the header collector.That too requires finding the correct length for the torque tube and it usually is where the torque tube starts to cool off is where you cut it.But that's headers.Exhaust systems and pipes of any kind are a real science? What works on one combo does not always work on another.There is sometimes some tuning and experiementation, involved, variaton in some respects,and using a base line and a rule of thumb ? I have enough better chambers that my first mind tells me to just use them ? And spend the time on something else.But my second mind is curious to see what would happen messing with the Wirges ? The mind is like a parchute ? It does not work unless it's open ? I listen to what everyone else says from their experiences and their ideas.That's the best way for me to learn ?

Long tube header actually make more low end torque, shorty headers just fit but are too short to work properly in an average v8...so they just make the primaries smaller in diameter, two stroke chamber are different animal. Way more complicated, not that I can really help you much with that...I'm still learning too

There is some basic but good information about chamber design on the resource site, in the form of books by Bell and Jennings. I'm pretty sure some or many of the chamber design programs are based on formulas from those books.

Yes you are absolutely right about the tube lengths, long more torque, and shorter more HP.Thanks for confirming that.Excuse me.That is what I meant.And I know that.Thinking backwards today LOL !! Differences in tube diameter and collector sizes too have an effect.Headers And two stroke chambers for sure are a different concept.Two stroke chambers need to be carefully designed.As previously mentioned by Jim even stinger length is important among other things.Like I said expansion chambers a science.Much to be considered and always a learning process.Lots of formulas and info used in their design found in many books available on the subject.All very interesting and facinating.

I may be only 29, but I've involved with hotrods since I was 14...read every magazine I could get my hands on...I love two stroke because it's completely different but with the same hotrod feel, and you triple guys are more passionate then any group of car guys I've ever met...kinda wish I bought a triple when I was 14 instead, probably would have killed myself though
