Ok... here are my findings:
The bare 2005 tank weighs in at 25.380 lbs. (11.51 kg). Disappointing! (I wanted it to weigh more!)
The ProAlloy tank weighs in at 15.480 lbs. (7.02 kg).
The two black chassis foam pads that are not reused weigh 0.681 lbs. (0.31 kg).
Overall net weight loss (including all hoses, clamps, foam, etc): 9.64 lbs.
Here's my latest corner weights with absolutely
no gas in the tank
LF 366 RF 359
LR 520 RR 528
Total
1773
Left 886 50.0%
Right 887 50.0%
Front 725 40.9%
Rear 1048 59.1%
LF/RR 894 50.4%
RF/LF 879 49.6%
So my Elise now weighs in between 1773 lbs. (804 kg) completely empty to 1861 lbs. (844 kg) completely full (54 liters, 88 lbs. of gas)... and no fuel surge on track!
I've updated my
home page with all the new weights.
Enjoy!
