    Fixing 2-Stroke Engine Issues for C125R Honda Motor

    I am in the process of working on a 2 stroke motor that I am looking into converting to fuel injection. One thing in particular that I find with the 2 stroke is that is less efficient than than a 4 just because fuel mixture goes out the exhaust port while it is still open. Is there any ideas...

    Exhaust and engine accoustics for asthetics and performance

    This is all in relation to a 90 degree v8 I am looking for the highest frequency/note/tone/pitch I can get. I very much enjoy the higher, crisper, cleaner sound the european v8 makes. I hate with a passion the rumble of the harley/dumptruck American v8. I have heard flowmasters on these cars. I...

    Chamber design (mufflers). I'm stuck,

    my lonesome have been working on a set of mufflers that don't sound like fecal matter. I am having a difficult time finding just the mufflers (race mufflers). I DO NOT want an entire exhaust system. I do have the capability of fabing up mufflers, I have custom made equal length headers to an x...

    How Does Acoustic Resonance Affect Frequency in Open Tubes?

    I am working with a 336.6 CID sbc. At 7000rpm VE is at 83.8. Peak VE is at right around 5500rpm being at 92.1 RPM is a factor of cfm, it doesn't make sense to me that cfm is not a factor in the sound and the rpm is seeing that they are related. The higher the rpm the higher the cfm and vise...

    How Does Acoustic Resonance Affect Frequency in Open Tubes?

    Accoustic Resonance of an open tube -- help please So I am trying to make sense of the different varying formulas that I have found. Some of the formulas are not fully explained hence my questions. This is a music related topic. I am attempting to figure out what the formula is to determine...

    Automotive Heads are tested need cam help (classic sbc)

    I thought you ment that there was a forum within the physics forums for chevys. Yes I am on a myriad of different websites. I like to keep my options open. I have had good help from the Physics forum in the past. Thought to post here and see what guys have to say.

    Automotive Small block Chev (classic) exhaust notes/tuning physics etc

    Where does one find said 4 pinion carrier? I have never seen them available for the r200. The heads are aftermarket AFR nockoffs that are getting done up by Travis knowlton at Knowlton's thunderhead in bethel mn. So I am not worried a damn about quench. He think I can take it higher on...

    Automotive Small block Chev (classic) exhaust notes/tuning physics etc

    Well I suppose that is the exact reason why I am here asking questions. Also I have been told to make as short an exhaust as I possibly can, for basically the reason you just gave. If I can get the headers from an x pipe immediately to a muffler that takes the exhaust out the side immediately...

    Automotive Small block Chev (classic) exhaust notes/tuning physics etc

    weekend road racer/street/show car I did three years of research before I bought an engine block, 6 months of research before I bought my heads, another 6 months of looking at every engine builder in MN before I chose a guy to do the heads and block. I am well acquainted with what I am doing...
