Wish I'd added the meter option. Great
charger though.
Heater1500 Watt Ceramic Heater
DC/DC ConverterIota DLS-55
Two wired in parallel along with a SLI
backup battery. The power steering pump
can draw up to 85 amps on a hard turn, so
one Iota wouldn't cut it.
InstrumentationeXpert-Pro
Top Speed80 MPH (128 KPH)
There was still plenty of throttle left,
and the car was pulling nicely. I need
somewhere I can really test it (legally).
Acceleration0-40 mph is much faster than stock, but
then acceleration tapers off. 0-60 is
just under 10 seconds. Stock was 7.5.
Range62 Miles (99 Kilometers)
In the interest of maximizing the life of
the batteries, I'll be limiting my trips
to 50 miles or less.
Watt Hours/Mile320 Wh/Mile
This is in average stop and go traffic. I
have seen results as good as 265
Watt/hours per mile.

Tires225/50 R16 Bridgestones that came on the
car. Will look into LRR tires when time
comes to replace these.
Conversion TimeFrom engine pull to out of the garage was
1 year and 3 weeks. There were about 5
months spent idle waiting on various
parts. All in all I'd estimate between
550 and 600 hours of work.
