Well I run a 12.7 @ 111 now w/ a 2.0 60'. That time is bouncing off of the rev limiter at the traps. I am going to goto Hypertech and get my limiter raised 300 rpms, but What will I need to do to rev to about 6300?

If I change the springs will that help? Also What all, if any, needs to be changed if I can get away with just changing the springs? Thanks Guys!

 

i think its generally recommended that if you are going to some higher rpms that new springs and some good retainers are a good idea.

 

I've gone to 6300 on stock springs and nitrous, no problems. But those were fresh, low miles motor.
