It's really hard to say. It's not a drastic difference by any means. I would say that it would outrun the green Jeep though. May have to see...haha.
The power really comes in around 1800RPM. It's pretty weak out of the hole, but from 1800 to rev limiter it does pretty good.
It's got 5:13's but 39's are pretty dang heavy.
In 4:1 it's very strong though. 1st gear is basically useless. It pulls 2nd gear hard. I wish it was a 5 speed, but I think the auto will help keep it together. In comparison to Neil's JK buggy, it has very noticeably more power.
