Re: It lives
So you had 10Hp missing AND got a record - I'd be happy with that

Re: Vespa Dry Lake Racer lives...
OK more info... Added the "Bad" Hp results (mapped against the 4 gears) and left the old good results (dotted lines) and then tweaked the Hp to overcome drag (red line) to emulate what happened at the lake. To fit the Hp to overcome drag I just added more frontal area (as I was not sitting...

Re: Vespa Dry Lake Racer lives...
How does the lower hp look with your achieved speeds , does it correct the calculations ? I'll need to do some more scribbling on the chalk board - I suspect the RPM on the chart is wrong as it is based on my rev counter and I don't trust it to be correct. The rear wheel speedometer reading showed ...

Re: Vespa Dry Lake Racer lives...
Good news?! The dyno run today shows me quite a few horses have bolted and I only have 22Hp (down from 32Hp) - this explains a lot! 1-2Hp is due to the side panel alone! This is probably even more at higher speeds due to even more restricted air flow - though I tried measuring a pressure drop on my ...

Re: Vespa Dry Lake Racer lives...
Actually I just found that I noted down my googling result and found a motorcycle version :) http://www.vespalabs.org/Projects/Scooter_Computer_II/Sensors/Wheel_Torque_Sensor but that is about as far as I got. Don't know where you get them or how much: http://www.gtme.co.uk/Torque.aspx?id=14 but it ...

Re: Vespa Dry Lake Racer lives...
I was talking to a guy at the canteen one night about dyno's. He had built one using a load cell like this. Easy conversion from ft/lbs to HP. http://www.ebay.com.au/itm/221386078007?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Very nice! - just added to my list of sensors to include - I ...

Re: Vespa Dry Lake Racer lives...
Yes - I need to hit the dyno - from last measurement if I put my engine in JP's bike it should have done 100mph ;) dplecko I'll also be blowing the dust off my homemade data logging kit (shelved after a long long exercise in discovering how to accurately measure wheel rotation speed). You have a pre...

Re: Vespa Dry Lake Racer lives...
More evidence that 32Hp should be enough - Tony O'Brien just got 116.2 mph in the UK! He has approx 32Hp but a lower frontal area.

Gary - hit your local tyre shop - they normally biff the old weights in a bucket. I got 30Kg for free

Re: Vespa Dry Lake Racer lives...
Paul, dose the "closeness" of the web indicate negative pressure regions, ??,, No that is just resolution of the mesh it was calculated with - think of it as a balloon in "opposite world" - if you could blow up a balloon with negative pressure that is the shape it would make. Ho...

Re: Vespa Dry Lake Racer lives...
Yes - low as possible is on my list but there are a few other things I am pursuing as the possible contributors... I estimate that 30 Hp should be enough for 100mph and after that a rapid increase in Hp is required to make small improvements (as we all know). dplecko your results support this theory...

Re: Vespa Dry Lake Racer lives...
Yes indeed - I still am scratching my head and need to dyno the scoot to see what is up. I went through my old dyno results and mapped it against gearing and even adding a 20% increase in frontal area (because I could not sit as low) and 20% increase in Cd I still should have seen 100mph. The way th...
