DIY Chevy Avalanche conversion to parallel hybrid

From the EVDL:

I am actually planning on trying this in a full size 2004 Chevy Avalanche.
I already have the batteries mounted and the charging system in place. I am
working with NetGain and will install the EMIS module due to arrive this
week. I am getting a special ADC 8: motor with a larger comm end so I can
connect it to the transmission and then attach the output shaft to a
shortened driveshaft. The motor should be here by the end of the month so
hopefully I can have the vehicle running by the end of the year.

In my 6000lb vehicle I was not able to tell any MPG drop due to the first
300lb of batteries. I now have all 12 installed so I am carry and extra 600
lbs which will grow to 800 with the motor. Time will tell if I can get a
noticeable boost in MPG. In the test done by NetGain they have seen a
25-30% improvement in in-town driving.

If interested you can see the plans to date at

Cool experiment, but what a waste. It's like trying to strap enough turbochargers and intercoolers on a V6 Mustang to get it to outrun a Mustang GT. Sure it's pretty cool once you've done it, but in the end you could just go buy the Mustang GT and have some pocket change leftover.
