To me its reliable and should be able to go well past 9k as well but I didnt feel like risking it. I was making power all the way to 8700 rpm and it would have still climbed.
Wow, not bad. Yeah, I was reading about that, you need the ve oil pump and RR lifters and it'll be similar as running solid lifters right? There's no advantage of that setup over actual solid lifters right?
What year/model and all that stuff did you get the RR lifters from?
And the twin grooved shims just keep the arm from sliding out or something like that??
Did you use different shims, or the ones that were already in your engine?
What size turbo do you have? That must be pretty awesome having that crazy powerband.
Thanks!
