300ex rev box

[exkid110]

I was wondering if anyone knew if they make a bigger rev box for the 300 and if so where could i find one

we carry one that increases the rpm's 1000.

how much is it for the rev-box that increases it by 1000 rpms

$49
We just drove through Papilloin NE last weekend going to the brooks IA harescramble.

What gains do you really see?
Will it hurt the motor in the long run?
Should this be done with a motor with no mods?
Are there any starting issues like I read on the 400, battery life stuff?:)
