    Rear Wheel Torque Values

    Thanks kcj, Yes it is at high speed I am interested in, much testing to do. I am building a 500cc motorcycle for a land speed record, if I can get the power I want out of this thing, a class record that is. Trials Bike riding is a skill on it's own, I remember when I was younger I used to race...

    Rear Wheel Torque Values

    Thanks kcj, Yes I am aware of the torque gain or reduction of different diameter sprockets. I am looking more at how the pitch radius affects the Chordal action & it's effect on various things. Thanks for helping out.

    Rear Wheel Torque Values

    Hi Mike, Maybe that's why nothing seems to make sense, can you help me with the correct formula's please. I have found many different so called formula's on the net that don't seem to be correct either. Basically I want to see if the pitch radius of both sprockets has an influence on the output...

    Rear Wheel Torque Values

    I found some differing equations on the internet than what I thought on how to arrive at the rear wheel torque value for motorcycles, so I thought I had better ask here to make sure. One site said Rear Wheel Torque = Chain Tension X Tooth Count Ratio (front & rear sprockets) I was under the...

    Piston skirt/rod length question/issues

    Gday Pat, I have to agree that the old IC engine will want to fire & run no matter what condition the internals are in, but you have to admit for a new build for a semi race engine this is really horrid work. It does look like the hone hasn't had much vertical movement at all in the honing...

    Piston skirt/rod length question/issues

    I'm surprised about some of the comments on the honing, that is an absolute terrible hone job, in fact it's not a hone job. The only worse hone job I have seen was two elephants mating at the Zoo! The engine is not going to make power with a finish like that--full stop!! Correct ring seal is...

    Honda Normally Aspirated B22 Exhaust Header Pipe Lenght?? Disscuss

    What is the application of the engine & what fuel are you using?

    Head Gasket

    Interesting reading some of the comments, brings back memories of head gasket woes. One thing years ago that was near sudden death to a head gasket was the quick cooling down of engines behind pace cars. We tried just about every machining technique, sealing compound etc some worked some not...

    Stirling Engine

    Gday Greg, FFFOORRD would love it, sorry that word is hard to say around here HaHa, especially on some Sunday's. Like always the BS stops when the flag drops. So, to banty around numbers without others actually being there to verify things becomes a little unrealistic, some will say WOW others...

    Stirling Engine

    Some time ago i was asked to look into a similar project for a customer, after testing many seal types etc i settled on Rulon. We also settled on Water lubrication between an upper & lower seal arrangement which worked great. The placement of the ring lands was critical in design & were kept...

    Brain fart, coolant system

    It would be a nightmare, just thinking how many times i have had to drop a bit of coolant out to repair something in a hurry, if this was oil--what a mess. Not to mention the danger of having cars run around dripping or spilling oil all over the roads or tracks. The system would have to be...

    Anti-surge turbo compressor housing machining.

    Forgot to mention that these jets can be used with & without the MWE groove, jets when used with the MWE grooves are then called J-Groove & not MWE groove.

    Anti-surge turbo compressor housing machining.

    NobleConcepts, Just wanted to make sure it wasn't Rotating Stall conditions. The fix to rotating stall conditions & mild & true surge are one & the same--well almost. By applying a jet--jets of air via active control to the comp impellor when approaching stall-surge conditions can & will make...

    Anti-surge turbo compressor housing machining.

    NobleConcepts I was thinking more along the lines of improvements & not de tuning as such. Just a question about your issue, Does your Net Flow Rate remain constant when you encounter what you believe to be Surge or are you getting a COMPLETE or Partial reversal of flow. There a lot of...

    Anti-surge turbo compressor housing machining.

    Just thinking, have you thought of controlling your surge problem to eliminate it before modifying your housings? This could make a very interesting & informative thread as there are members here with good Turbo knowledge. Warpspeed & Pat come to mind among many others.
