DTM Brian Posted March 4, 2009 Report Share Posted March 4, 2009 1. Does anyone have bicycle they can donate for this. Possibly bring it the day before the dyno day or in the morning? 2. Should we have a set amount of time to pedal the bike? Say 20 or 30 seconds?3. Do you want to offer a reward for top speed?4. What time in the day do we want to do this? I would like to limit it to know more then a 1/2 hour so we can make sure all customers are taken care of. I have a feeling I am going to be extremely busy.5. If people want to pay a sign up fee of say $5.00 bucks, I will give away gift certificate good for some dyno time to be used at a later date. I am thinking possibly an hour of dyno time which is a $75.00 value. We can use the sign up fee to either donate to the forum or pay towards our food and drinks. I am already donating $5.00 per bike that I dyno to Ohio Riders. Let me know your thoughts. I would like to have this somewhat organized.I almost forgot. Who is going to win?????????????

kawi kid Posted March 4, 2009 Report Share Posted March 4, 2009 Are you saying we should have a prize for the lowest power?Hmm.What would that prize be? then the crippled kid would walk away feeling like a winner i think you will be best doing just highest speed and hp. unless you wanns throw a handicap out there Quote Link to comment Share on other sites More sharing options...

wrillo Posted March 4, 2009 Report Share Posted March 4, 2009 don't you need rpm's to get hp? how you gonna work that out? Quote Link to comment Share on other sites More sharing options...

Benyen Soljax Posted March 4, 2009 Report Share Posted March 4, 2009 don't you need rpm's to get hp? how you gonna work that out?http://en.wikipedia.org/wiki/Dynamometeryou can have massive torque at low rpm. Quote Link to comment Share on other sites More sharing options...

wrillo Posted March 4, 2009 Report Share Posted March 4, 2009 (edited) http://en.wikipedia.org/wiki/Dynamometeryou can have massive torque at low rpm.okay, so what is K then?edit: the only way to find power without knowing rpm, would be if speed was constant... you gonna pedal a constant speed? count me out... I don't wanna play bicycle hp game anymoreedit # 2: ohhhhhh... so if the dyno forced a constant speed, would that be an "active" dyno?

DTM Brian Posted March 5, 2009 Author Report Share Posted March 5, 2009 When using an inertia dyno you do not need rpm for horsepower. You do need rpm for torque. Quote Link to comment Share on other sites More sharing options...
that dude Posted March 5, 2009 Report Share Posted March 5, 2009 care to explain? I really don't knowso are you in or out? Quote Link to comment Share on other sites More sharing options...
wrillo Posted March 5, 2009 Report Share Posted March 5, 2009 okay, I get it all now. I searched inertia dyno and got some good results. I was thinking inertia dynos measured hp, but they don't. They measure other stuff then use the moment of inertia of the drum to find hp, so it makes sense now.so are you in or out?yeah I am, I should kick some arse Quote Link to comment Share on other sites More sharing options...
wrillo Posted April 3, 2009 Report Share Posted April 3, 2009 Is this still happening? Quote Link to comment Share on other sites More sharing options...
DTM Brian Posted April 3, 2009 Author Report Share Posted April 3, 2009 Is this still happening?To be honest I am not sure. Really depends on how long the line is to dyno. I want to make sure everyone who wants to dyno is taken care of. Quote Link to comment Share on other sites More sharing options...
Dweezel Posted April 3, 2009 Report Share Posted April 3, 2009 http://en.wikipedia.org/wiki/Dynamometeryou can have massive torque at low rpm.Thats my preferred method Gobs of TQ below 5k rpms will give you good hp numbers (muscle car method), or you can spin it to 50k rpms (Import method). HP=Tq*RPM/5252 There is no such thing as HP, it's a number achieved from mathematical formula. Torque, is a measurable twisting force around a center point that can be measured, nominaly in Nm or, Lbs/Ft. Quote Link to comment Share on other sites More sharing options...
mrbret Posted April 3, 2009 Report Share Posted April 3, 2009 I'd be up for this as long as i'm not working.Whatever bike you use better be able to take the life being peddled out of it. Quote Link to comment Share on other sites More sharing options...
