Yes you have really read TUNING.. and i dont mean the "tuning" most website are offering like adding cf spioler, racing rims etc... .. but MOTOR , Controller and battery tuning !!
I would dream having someone asking me to hack his Tesla for drag racing performance purpose!
ONe of the first thing i would do is remove that big 90kWh battery pack and replace it by LiPO !!
In fact the Tesla S use a 1200 pounds battery of 90kWh that is useless for drag racing!
It contain 96 group in serie and is capabel to deliver 1500Aburst.
Now with the top performance LiPO actually availlable how much weight and what performance gain ww could obtain!!
The Known Lonestars lipo in the National Electric Drag Racing Association ( NEDRA), many, including me are using the true 100C lipo they offer. These are in a 4.5Ah pack.
Now the question is howe many of these LiPo cells and what weight reduction we could acheive!
let's calculate a bit:
let assume we use the cells to 50C for more safety purpose: This represent 225A per 1P cell.
The P90D can take 1500A so that's about 7p
The Tesla use voltage that use 96 in serie so for a drag racing lipo pack that would be 640 cells for a total of 11.8kWh and weight
Each cells weight 114g. That mean for 640 cells that's a total weight of just 160 pounds !!!
The original battery weight is 1200 pounds... so we would save 1040 pounds !!! :wink:
Now what it represent...:
original weight is 4647 pounds
New weight: 3607 pounds 8)
a diff of 23% less weight !!
The actual E.T on teh 1/4 mile according to the test that Motor Trend did is 10.9s.. and it still really impressive!
Now with 1040 pounds of battery removed the calculated E.T drop to 10.009s !!!
