Re: Noosa EV Expo, Sat 22nd June 2019

I was signed up to attend. But I had to withdraw as my car is unregistered and they are asking for a copy of my CTP. It was a bit late for me to organise any way around it. I am disappointed as I enjoyed the event last year. But at the same time it is my wife's birthday and she wasn't totally happy ...

Re: Electric Motorkhana and khanacross car

It's generally good practice to have more than one contactor anyway, though not really a rule as such. Interesting. I assume the two would need to be in series? Otherwise a failure on one would not be compensated by the other. Also would you be able to just have the Precharge resistor across one co...

Re: Electric Motorkhana and khanacross car

Zeva bms checks for earth leak. There are others too. Thanks, yes that is the system I have. As you say it does provide a warning and it would probably disconnect the contactor if a leak is detected but the precharge resistor would still complete the circuit. So it really depends how they write the...

Re: Electric Motorkhana and khanacross car

Thanks Bryce, Yes that is one of my goals, to make people realise the shift to EVs does not spell the end of grass roots motorsport. Not much resistance. Some people just lack interest, and just walk past without more than a glance. Some are very interested. Some would even follow the same path but ...

Re: Electric Motorkhana and khanacross car

Absolutely. It is a hoot. Even after shoving my nose in the nuts I cam away smiling. It might not have been the case if there was damage. Keeping the cost low and having fun are my main two objectives. Times and results are a secondary consideration. I would love to attend Mt Cotton more frequently ...

Re: Electric Motorkhana and khanacross car

I had a great day at the Mt Cotton hill climb. I only managed a 52 second lap which isn't too impressive but not too bad for a first attempt. I need to learn the track and get brave to achieve better times. But the main issue was brake bias. I need more brake power in the back. I had to brake way to...

Re: Electric Motorkhana and khanacross car

Hi all, I will be competing at the Mt Cotton Hill climb tomorrow. It is an informal day but should still prove interesting with the torque of the Batt mobile. I haven't had much track time at Mt Cotton and it has been quite a few years. I will go on record as saying the following: A sub 50 second ru...

Re: Electric Motorkhana and khanacross car

Thanks. The torque is great for motorkhana as it is for other standing start forms of motor sport. I have struggled to strike a good suspension setup though. It is starting to come good. My design is a bit of a compromise as I am not willing to give up hill climbs and khanacross in order to be outri...

Re: Electric Motorkhana and khanacross car

Its been a while since I last posted here. To be honest there really wasn't that much interest from this group. But anyway I figure it is probably time to post an update as a lot has changed. I ditched the old chassis as I was losing too much acceleration through front wheel drive wheel spin. I have...

Re: EV autocross

The motorkhana i've competed in in australia reverse is not allowed, if you engage reverse, you get the slowest time plus a penalty. All you need is a suitably scrutineered car, long sleeve cotton clothing and helmet. It would be ideal for EVs. And i reckon you'd have a fair chance of doing all rig...

Electric Motorkhana and khanacross car

I have lined up a new controller. I am going for the 1000amp variant. I believe I will be able to easily double the power compared to how it was performing before. It will be about a month before I will have it all installed

Electric Motorkhana and khanacross car

Yes, other than the extra expense I am not too upset. Luckily the failure on this event was on the last run. At the event we did two attempts at each test and the best time from each pair counted. So I really didn't lose much. The past two events have been motorkhanas. The car is unlikely to ever be...

Electric Motorkhana and khanacross car

Didn't go to plan. The car and driver were performing reasonably well. Although the car performance was OK it certainly wasn't up to the level I would expect from the combination. But it was still an improvement on previous attempts. I was fairly competitive, at the time I expected to be top 3. It t...

Electric Motorkhana and khanacross car

It's difficult to quantify how much more potential it could / should have. But think of it this way. This setup is normally used for great results in road cars up to around 1200KG. I would expect that to mean 0-100 in say 8 seconds and a top speed around 110kmph assuming no gearbox is used. In mine ...

But am I understanding that your 178wh pack is 56kg? If thats the case it won't work for me. My total battery weight at the moment is...
