06 six speed 5-114 w/brembos

i did break in for 750 miles. i had my tuner remove the rev limit he put on during break in. my question is what is safe to rev to(fuel cut is 7400 right now)? by safe i mean 100% no worries what so ever safe. the car is only at 15psi right now on 91 w/o meth. should i stay in the 7500 range?

i dont know it all what so ever, but i have done tons of research. From what ive read, our cars (subies) arent built for high revving. Your setup IS built compared to factory setups, but i doubt your going to get much up top anyways. just my .02. Hope some other more experienced members can chime in.

I would not push it farther then stock rev limit. You do not have anything in your build that will support high rev. Where is your hp peaks?(rpm)

+2 on both accounts.
I also see you have an 02 and that would mean you have shim over buckets for cam lash...those and high RPM aren't exactly friends

i havent had it on the dyno yet. should i lower the redline to 7200 then? the car is daily driver and must be reliable so im not worried about maxing it out anyways.

How do you figure that? My bike motors all have shim over bucket.

And they have a lot lighter valvetrains and they are not Subaru motors.

Very good question. As long as there is no valve floating, shim over bucket is OK. However people will switch to shimless buckets to reduce weight of the valve tain thus being able to rev higher.
