Stall change on N20

[Super73]

I’m wondering what is seen as far as stall flash difference between motor and N20. If you could fill me in on the following, that would be great.

Weight of car
Rear Gear Ratio
Tire size
Stall size
Current RWHP NA
Current N20 shot (out of the hole)
Flash speed NA
Flash speed on the bottle


Thanks in advance.
