Oh, and send an email to Big O. With the gov't now owning a big chunk of GM, and full electrics are the future, I'm sure it would be easy to get approval to refit/improve the EV1 to become the EV1.1 or EV2.

JCG wrote:Hi Luke, still shooting for an ammonia-powered spark ignition engine that will run at around 20:1. I have a friend in Michigan working with me on this at Eliminator Products. I think it'll be fuel-flexible (diesel, propane, or ammonia) but that's a job for this summer. The generator head needs to be rated around 30 kWe or so. With luck and those high compression ratios, we'll be knocking on the door of 50% efficiencies (early dyno tests confirm). We really just need it to fit in the trunk.

evdriver wrote:Seriously, you have bigger issues to deal with.
(1) Look under the dash, drivers side, kickpanel. Yeah, all that dangling crap is where the BTCM used to be.
(2) Now go over the passenger side and look in the same area. A ghost of where the HTCM once resided.
There's a couple more surprises lurking too.
And after all that; you can't drive it on the streets.
JCG wrote:Well... it's not so bad as all that. I'll be able to operate without the BTCM, as standard brakes still work (no ABS functionality though), and the repaired inverter has inputs I can use to directly connect potentiometers to run traction and regen braking signals.
evdriver wrote:It's not just ABS. There are no standard brakes on the EV1. The EV1 uses 4 wheel electric brakes. The two front wheels also include a small emergency hydraulic backup (without assist) that GM's lawyers demanded be included just in case the EV1 brake by wire system failed. You'll need both feeties on the brake pedal to stop it using those front only emergency backup hydraulics.
Don't get me wrong, I applaud your effort. Posting that you'll operate it without a safe and functional brake system makes it difficult to take your efforts seriously.
The EV1 braking and steering systems are both unique in that they are electro-hydraulic systems. The front disk brakes are hydraulically actuated and powered by electrically driven pistons (12-volt power); the rear drums are electrically actuated (12-volt power).

IIRC from the brochure the 88-91 crx was .29 and the 88-91 civic hatch was .31.. probably a little on the optimistic side.
