CALBs? Discharge?

[DIYguy]

Looks nice though. Shiva will definitely be starving. Might be a good idea to run the motor cables together also.

What blowers are they using?

Please use more words. Are you saying that CALBs suffer a discharge problem? Are you asking how many amps they get? Hard to tell. Please elaborate.

The car has more power than traction, so not sure I would say the controller is "starving". Not maxed out is different than starving.

I say nice job.

Definitely a nice job.
Calb's will only do about 8C maybe 8.5 and they need to be warm to do that. So, 200ah cells will give you 1600 amps or so. Roughly half of Shiva's capability. Just seems like an odd match. . however, they have other battery plans so, it's just a start. As for traction, it's likely the wheel spinning was purposeful. Of course this can be solved if desired. . . where current limitations are a bit tougher.

ONLY 8C!! my how times have changed. 3C used to be considered a lot.

You can't really do anything to fix a rwd car. Oh sure, bigger tires, weld the diff, but that is only mildly effective. Mate Rimacs BMW shows that rwd can only be taken so far. If it was a Subaru or DSM it would be MUCH faster. BMW doesn't win any rallys. There's a reason. RIP 2wd.

p.s. I live in MT so 4wd is a must.

yes, times have changed. Now lipo is looking at 130C and higher.

ACtually, the comment about RWD is pretty much off base for dragging. RWD makes the best dragsters. Mate's car with the 11hv was putting 650hp to the wheels or something like that. Keeping this amount of power stuck on RWD is easy done. Many burnout shows are done on purpose. Brake stands, line lock, slight quick turn of the steering etc. Cars much fast than mates have no problem sticking. Even John Waylands Datsun running 15" DOT radials (street tires) runs low 10's. Quite a bit faster than Mate's at the time. John Metric, Shawn Lawless and Olly's Black Current all run 9 seconds with RWD. Of course ICE RWD cars are running much faster . . . in this discussion, it's not so important what is generating the power. Sticking 1000 hp is easy done with the right RWD set up.

For Rally driving sure... 4wd. . but this was not the discussion.... I don't think...
