NuVinci CVP Transmission

[checkered]

Are these

the rules you have to abide by? http://www.greenpower.co.uk/racing/rules_f24.php ... I suppose one of these motors is customised for the series: http://www.fracmo.com/english/motors/index.htm ... had a tougher time finding the exact batteries (by specification) in the Yuasa website: http://www.yuasabatteries.com/index.html

Checkered - They are indeed the rules we abide it's quite a nice formula but they just keep getting tighter. If any of you visit the forum there my handle is Horsfallracing.co.uk and if you type in NuVinci CVP into youtube you should find some short videos of us testing at our local supermarket. (dw I had permission.)

Carlos - The plan was originally to lower the driver below the bodywork however the rules now forbid that as the drivers head needs to be visible from either side and from the front to form more of a cockpit.

I currently have a 3" pipe running from the front of the car over the motor then out of the back. I have also included a small rear diffuser since the start of the season. I may add some water cooling as well - possibly into the airline to atomise the water and thus cool it quicker/more efficiently.

At the moment I am looking to make the car more aerofoil shape in plan veiw however this is proving rather difficult with the wheel base, track, max width and max length rules. luckily I can use a Kammback to get the rear pretty good but the front end is proving rather tough. I have 3 weeks until my last race of the season at Goodwood under the "F35" formula with the same car and I feel that at the moment we have reached the limit with this shape especially given the fact that we now have to have an average draw of around 20-23amps to survive the distance.

The plan is to just run an interim bodywork made out of corregated plastic (correx) which can be done in very little time.

Sorry to hijack the thread but I really want to go all out to make this a good car.

I was looking at a picture a few weeks ago of a '68 Brabham F1 car that was testing a vacuum formed lexan bubble top that looked like a WW11 fighter plane canopy with a section cut out of the top so the driver could shimmy in. Maybe make one out of coroplast clear . Put it on and take it off with snaps. Some e-motors have a water jacket. Was there a thread that included your car greenpower dude reloaded? I think so.

Thanks for the links checkered. I'll look through the the rulebook first.

About the NuVinci, I´m not that familiar with the liquid it uses but there´s no way it can handle anything above 500Nm, right?

EDIT: the bike hub handles 130Nm with 6 balls, so one ball handles 20Nm
500/20=25 balls
