Don't know who pays for electricity but now there is a big Supercharger box there (pix on Recargo) Will that also be free land? Maybe if the proprietor thinks the car owner will be buying overpriced snacks and burgers but will this always be the case for land (parking for two cars) and power?vfxhttps://www.blogger.com/profile/17374947704873793916noreply@blogger.comtag:blogger.com,1999:blog-6676835811534572362.post-25013039130465541592012-06-30T21:06:53.345-05:002012-06-30T21:06:53.345-05:00Figured it OutFigured it OutMarkhttps://www.blogger.com/profile/14514315717843004115noreply@blogger.comtag:blogger.com,1999:blog-6676835811534572362.post-54961039912338292052012-06-24T02:58:44.955-05:002012-06-24T02:58:44.955-05:00That gear calculator is real handy, I will have to...That gear calculator is real handy, I will have to add the link to my favorites. :)<br /><br />I feel the torque provided by the 11HV is great at 1000 amps and would like the car to last a long time, especially keeping the gearbox in place.Suzahttps://www.blogger.com/profile/17045521635067750085noreply@blogger.comtag:blogger.com,1999:blog-6676835811534572362.post-35330731891119018972012-06-23T20:36:41.349-05:002012-06-23T20:36:41.349-05:00Hey guys,

IRS 2.73 differential.<br />You will notice that the gearing,(shifting m.p.h.) is still lower than the stock i.c.e. combination, but then again you will not be making as much horsepower and you are not concerned about going fast.<br />http://xse.com/leres/bin/gearratio?title=SS+%23670+with+MM6+manual+and+3.73+gears&rpm=3000&mph=100&gear1=3.48&gear2=2.02&gear3=1.39&gear4=1.00&gear5=0.79&reverse=3.28&axle=2.73&tire=diameter&diameter=26.00&circumference=81.68&revs=776&section=&profile=&wheel=<br />So how do you mount this Ford 8.8 I.R.S?

This occurs with a WarP9 starting at almost 0 RPM and continues up to around 3700 RPM if your voltage is high enough. and you can feed the motor 800 amps. You can see this in Jack's dyno graphs from Speedster Redux. The Tuesday April 12 2011 blog includes these graphs. This is a wider range than the original motor, it is just shifted down into what is actually a more useful rpm range. So a WarP9 equipped 3rd gen RX-7 could be faster than factory.<br /><br />I didn't mean to imply it is a heavy car, it isn't but it is heavier than the earlier cars.

Not everyone wants to do that and for what ever reason he has it is just fine. It's his choice and he has that right to choose. I actually agree with Jack about the URL issue. Forcing me to exclude URL's when I should be able to do so is just plain wrong. I hate it. It sucks. I want to turn you to MY site. YouTube wants you to stay on YouTube. In that light they totally suck. Far from Girly to get ticked because of that. It is a BUSINESS and PERSONAL decision. If I could afford a different avenue I would. I don't do enough video yet to warrant moving elsewhere. So it is YouTube for me URLless and all. <br /><br />There are other play grounds to go play in you know.Pete McWadehttps://www.blogger.com/profile/08288980906309612950noreply@blogger.comtag:blogger.com,1999:blog-6676835811534572362.post-64556346166754915342012-06-22T04:05:38.191-05:002012-06-22T04:05:38.191-05:00Doug,

Thanks for the information regarding the 3.909 final drive ratio.<br /><br />The plan is to build the car as it is and then make changes to the transmission when needed. It would be nice to have the gearing set up so that rpms would be ideal at 55mph or so regarding efficiency.<br /><br />Yes, the car is a bit on the heavy side, but I guess it could be worse. I'm aiming for a 60 mile range and using the EVSource battery calculator it seems quite attainable with enough of smaller cells.<br /><br />Top speed is really not a priority.Suzahttps://www.blogger.com/profile/17045521635067750085noreply@blogger.comtag:blogger.com,1999:blog-6676835811534572362.post-88607086971149111422012-06-22T03:14:39.164-05:002012-06-22T03:14:39.164-05:00You're quite welcome Mark.

As you know, we recommend a very light scrubbing of mostly the tops of the battery terminals, which take on a patina of corrosion and oxidation - sometimes almost imperceptible as Aluminum pretty much protects itself with an almost molecular thin layer o oxidation which forms in minutes.<br /><br />By "brightening" those terminals just a bit with that abrasive sponge, you do a surprising amount to ensure a clean tight electrical connection.<br /><br />Those straps and washers seem like a very simple incremental improvement. I would say that more than any other thing, those tiny bits of metal represent more accurately what we've learned about battery care than any other single thing.<br /><br />They're a couple of bucks at Lowes. Little enough to include in the shipment and save you a trip down to the hardware store.<br /><br />But yes, pleased you noticed.<br /><br />JackJack Rickardhttps://www.blogger.com/profile/15936311474215791697noreply@blogger.comtag:blogger.com,1999:blog-6676835811534572362.post-76090655739167453882012-06-22T03:02:21.458-05:002012-06-22T03:02:21.458-05:00Indeed, indeed.

Just don't use first gear anymore and maybe not even 2nd. This will push everything up where you want it to be. The Wankel peak torque is way up high, around 6000 RPM. The big series DC motors start to drop off about half that. So you start out in a higher gear and shift early. If you want to get to 300kph for a top speed you will need to change things but the car will be more than just fine to drive around. For not too much money you could change the final drive ratio to 3.909 (down from 4.100) but this isn't really enough to notice.<br /><br />The third gen RX-7 is on my short list for my second conversion. They are certainly pretty cars but quite a lot heavier than the 1st gen.Doug Ingrahamhttps://www.blogger.com/profile/07850270222054815728noreply@blogger.com
