Re: Electric Motorsport - Hillclimbing and Sprinting

Did you see the Race of Champions last month? They had some Tesla Roadsters on track. The crowd were puzzled to start with by the lack of noise after the wailing V8s that preceded them, but I think they were won over in the end. The lack of noise from EVs is both a blessing and a curse for motorspor...

Electric Motorsport - Hillclimbing and Sprinting

I thought some of you may be interested in the conversations ongoing at Uphill Racers about using electric power in hillclimbs and sprints, where cars compete over distances of no more than 3 miles. It's the ideal application of an EV in motorsport, I think.

Re: Electric Hill climbing/motorsport

The Blue Book says (J5.1, page 152) that electric cars should contact the MSA directly for "additional requirements" which is what you've had confirmed as something they've clearly yet to define! As far as Modprod goes, it's all a bit hazy when it comes to kit cars. So many engine options ...

Re: Electric Hill climbing/motorsport

You could possibly enter as road going (if it is road legal). I haven't raced for a few years but I seem to remember that that road going cars had to be filled with pump fuel. So is mains electricity classed as pumped fuel? Maybe you could argue that you don't need fuel, depends on how the rules ar...

Re: Electric Hill climbing/motorsport

The Blue Book doesn't specifically ban electric cars but it does say that there are extra regulations that you need to contact the MSA for. When I spoke to the championship coordinator of the British Sprint Championship, he said that they'd worry about regulations for an electric car when one was ac...

Re: Experiment with li- poly batteries in a greenpower racecar

One big advantage of your approach is that ultimate hp isn't the primary factor with a sprint car, as you know. Getting the highest possible torque to the wheels, commensurate with maintaining traction, is what counts, as it's almost always acceleration, rather than top speed, that determines the w...

Re: Experiment with li- poly batteries in a greenpower racecar

I've been looking at the PolyQuest XF LiPos, but it seems the new PolyQuest NanoTech have similar power density for half the money. About £130 buys 20Kw of peak power (12S1P) with the 5Ah Nanotech cells from just 2Kg. I could build a 100hp pack for about £500 and under 7kg, which makes the power sou...

Re: Tyres

Bit like the way they waffle on about changing caravan tyres every x number of years :roll: That's because caravans are often to be found scattered across the road in small pieces after a tyre blow-out. I suspect it's down to the fact that they sit dormant for 51 weeks, then travel a few hundred mi...

VW Audi Group's W12 engine sounds fantastic - I'll take one of those, please!
