what the limit to how how rpms you should go on stock internals im going to change it from 5500 and want to know how high i can go

 

I would not go over what it is now, I forgot what the max is but it's not much more than where your at now.

 

i have mine re tuned and still have it at 5500rpm's this will save your tail if for some reason you go in to neutral or something happens while your pushing the car.

Also it is a good idea to allow you to go over the gov. but at the same time will not allow you to hurt the motor as easily
