Thats pretty impressive, considering we (Fenton's locality) had a 30C day yesterday!

Edit: put me on the list too PLEASE!

Also, don't worry guys... lots of folks out there will take over your 250's. I have a line up waiting. The 250, will be more than enough to overjoy, countless enthusiasts with cars that can't handle any more, but will be an absolute blast with this system! In fact, I wouldn't be in too much of a rush to let them go just yet. More work has to be done yet... Fentons testing is promising, but you already have an extentively tested, and proven system available. I just totally walked, all over a 2013 Lexus RX350 (0-60 in 6.4 sec., 14.7 sec 1/4 mile), with my 1993 Camry (0-60 in 8.2 sec., 16.5 sec 1/4 mile), to 60mph, yesterday in 30C heat, and the car was still walking away at that point. (4 car lengths!) Rolling runs are actually a little more impressive, because I run into traction issues, launching at full power, due to traditional, front wheel drive issues.

This is great news, but you already have some pretty darn good stuff.

THIS^ Also don't feel bad I have traction issues with RWD just the same lol

That's some wonderful news Fenton and rob?
Got a question though
When I order the 250tq kit can I get the new beefed up parts " controller, wires and other misc " that's for the 300tq setup with the 250tq kit
That way when I upgrade to 300tq I can just get the compressor

I just thought I might through this into the mix for Fenton. At certain locations, you can buy 94 octane fuel from Husky/Mohawk locations. I used to use this stuff on my 14psi boosted Mazda, and it is still apparently available at selected locations. I wonder if it might be a good substitute for e85?

Its actually available at pretty much every location. My car has never seen a drop of anything else.

No it is not a replacement for e85. E85 is about the same as 105 to 109 octane because of its knock resistance and the fact that it cools the charge.

The knew parts will be more money and they are not in production yet...actually just went into test last week on my car. There is only one kit in existence and its on my car

All the wires are connected to the controller so its kind of a packaged deal. The wires around the batteries and the aux charger remain the sane as the base kit.

I'm really enjoying driving my car again. It can get pretty boring NA. Now it goes like a bat out of hell. The E85 tune is really nice.
But I noticed something different. My voltage meter used to always read 28.7 as default voltage. Now it reads 28.5. And it used to recharge super quickly. If I did a 0-80 mph run full throttle it would take less than 5 seconds to come back to 28.7. Now it takes a lot longer. I used to wonder why anybody would need the aux charger but maybe now I need it. Do you think that maybe I had the super secret experimental super rapid charge version and it just didn't hold up?
Another possibility is maybe the batteries got damaged by sitting idle for a couple weeks.
I don't know. I'll run it for a couple days and see if it goes away.
Now don't get me wrong. I'm not bitching or complaining. Just stating an observation.
The car runs fantasticly and I would never give up my ESC.

Your voltmeter behaves as mine always has.

My "resting" voltage is 28.7 - 28.8. If I do more than a 2 second burn, the voltmeter will quickly recharge back to 28.4, but it'll be a good 10-15 minutes before it gets all the way back to 28.8. I've never thought anything of it.

I don't think I've ever seen more than 28.5. If I leave the ESC switch on in the car overnight, it reads 28.2 when I start the car and gets up to 28.5 shortly thereafter.

Completely normal. Just because it doesn't read 28.8 doesn't mean it isn't charged. As soon as back stable in the 28s you are "full"

Rob has explained this to me a couple times but I don't remember the details.

When I was without mine for awhile it recharged slower as well. A few weeks in all went back to normal.

If I get the chance and remember, I'll take a video of the rate of discharge and recharge and post it... I'd be curious to see how similar/different it is from others.

.

Than batteries aren't "damaged" by sitting idle for for a few weeks, but they do need to be conditioned. When the battery pack is fully reconditioned, you will note the recharge rate that you enjoyed in the past.

Regarding the recharge rate, it's always 8:1. However, with well conditioned batteries you have a certain amount of reserve with the first few engagements of the day, so the recharge rate is somewhat better then 8:1. After that reserve is depleted , you're back to 8:1. If there is considerable delay between engagements, you once again build up that reserve.

Regarding the voltage, there is a tolerance of +/1 0.2 VDC from controller to controller. I've had four of them and they all had a different charge point. My current controller sits at 28.5 to 28.6 VDC.
